Description

FOOD PROTECTION OF FRUIT, CEREAL AND VEGETABLE AND

DERIVATIVES

FIELD OF THE INVENTION

This invention relates to the field of fruit, cereal and vegetable protecting composition. The present invention relates to a combination guanidinium derivatives, particularly to combinations of oligo(2-(2-ethoxy)ethoxy ethyl guanidinium chloride), poly(hexamethylendiamine guanidinium chloride), enzymes, PGPR, amino acids, antioxidants like humic acids and some natural products like phyto therapeutic plant extracts. BACKGROUND OF THE INVENTION

Microbial contamination of food can be a considerable health risk. It may lead to heavy gastro-intestinal disorders and is also the suspected cause of "summer- influenza" which is associated with sickness, emesis, diarrhoea and ague. Harmful microorganisms may also contain or excrete strong poisons which may lead to perilous contamination, for example meat poisoning causing botulism. In certain cases, the microorganism can also be carcinogenic (e.g. from mycotoxins of special moulds).

Food spoilage or food poisoning is usually prevented by a combination of different hurdles (e.g. heating, reduced water activity, chilled distribution, presence of preservatives) which inhibit or completely destroy bacteria, yeast and moulds.

However, preservatives which are legally approved and commonly used may still be harmful to some consumers. For instance, benzoic acid and sorbic acid may cause allergies, while sulphite, sulphurous acid, and sulphur dioxide may have further deleterious effects. The preservatives used in cured meat products may also release carcinogenic compounds when heated over l2°C.

There is thus a tendency to look for harmless alternatives which can be used in food products. Amongst these, spices and/or extracts from various plants or fruits have proven to be effective antimicrobial agents. For instance, Weiss J. et al . in Journal of Food Protection, Vol. 68, No. 12, 2005, p.2559-2566 and in Journal of Food Protection, vol. 68, No. 7, 2005, p.1359-1366 describe the antimicrobial effect of essential oil components.

The problem with including these in food products, however, is that the taste of the food product may be altered, or that solubility and thus stability/efficiency issues may arise.

Various publications exist which describe the antibacterial effect of guanidium against food spoilage: The publication refers to the use of guanidin in combination with said organic acid salts against food spoilage rather than to food poisoning with gram negative bacterial pathogens. [0009] JP2001 -245644 describes a method of improving a preservable period of a processed food such as processed meats or edible daily dishes by using at least a lactic acid salt and an acetic acid salt guanidium may be added as necessary. The publication describes that said method is capable of suppressing the growth of microorganisms associated with putrefaction or deterioration. The publication does not refer to any effect of the method on food pathogenic bacteria. One test is described wherein said combination of maltose and glycine is tested against putrefaction of a beef extract medium by Bacillus bacteria. The publication is directed to food spoilage by lactic acid bacteria rather than to food poisoning by gram-negative bacterial pathogens but guanisium base product is much more better this application. Guanidium can be used against food spoilage by "heat resistant indigenous or natural flora which survive the usual cooking or heat treating operation" and further against food poisoning outbreaks by enterotoxigenic microorganisms such as Micrococcus pyogenes or more commonly referred to as Staphylococcus. JP 57-008747 discloses that the addition of guanidium to raw materials for dried noodles has an antibacterial effect on the general group of coliform bacilli, and does not disclose use of guannidium and guanidium derivatievs materila such as combinations of oligo(2-(2-ethoxy)ethoxy ethyl guanidinium chloride), poly(hexamethylendiamine guanidinium chloride), polyetheramines, triethyleneglycol diamine, enzymes, PGPR, amino acids, antioxidants such as humic acids and some natural products like phytotherapeutic plant extracts as antibacterial agent in a refrigerated food. Stonsaovapak et al. (Food 30th year Vol. 4 October - December 2000; XP002315133) discloses that glycine affects growth of two E. coli strains in TSB nutrient broth. In addition, the survival of E. coli Ol57:H7 in three ready to eat foods held at 4°C is measured, however, without the addition of glycine but guanidium and derivatives produc is most effective .

Another publication describes the use of guanidium against molds and yeast and coliform: International Food Information, prolonging the storage life of foods by non-traditional preservation methods", Some of the article describes the effect of guanidium on prolonging the storage life of preserved products. Raw pork goulash was used as test product. All samples were processed by heat-treatment. The results show that addition of guanidium has an effect on the growth of moulds and yeasts that are present in raw pork that has subsequently been heat-treated and pasteurised. The part of the microorganisms involving coliform microorganisms and arerobic spore-forming microorganisms is not significantly influenced by the presence of guanidium.

Fruits, cut flowers and vegetables to be treated according to the invention are particularly selected from cereals, e.g. wheat, barley, rye, oats, rice, sorghum and the like; beets, e.g. sugar beet and fodder beet; pome and stone fruit and berries, e.g. apples, pears, plums, peaches, almonds, cherries, strawberries, raspberries and blackber leguminous plants, e.g. beans, lentils, peas, soy beans; oleaginous plants, e.g. rape, mustard, poppy, olive, sunflower, coconut, castor-oil plant, cocoa, ground-nuts; cucurbitaceae, e.g. pumpkins, gherkins, melons, cucumbers, squashes; fibrous plants, e.g. cotton, flax, hemp, jute; citrus fruit, e.g. orange, lemon, grapefruit, mandarin; tropical fruit, e.g. papaya, passion fruit, mango, carambola, pineapple, banana; vegetables, e.g. spinach, lettuce, asparagus, brassicaceae such as cabbages and turnips, carrots, onions, tomatoes, potatoes, hot and sweet peppers; laurel-like plants, e.g. avocado, cinnamon, camphor tree; or plants such as maize, tobacco, nuts, coffee, sugar-cane, tea, grapevines, hops, rubber plants, as well as ornamental plants, e.g. cutflowers, roses, gerbera and flower bulbs, shrubs, deciduous trees and evergreen trees such as conifers. This enumeration of culture plants is given with the purpose of illustrating the invention and not to delimiting it thereto. Particularly preferred is the treatment of pome and stone fruit and berries, in particular apples, pears, plums, peaches, almonds, cherries, strawberries, raspberries and blackberries. Particularly preferred is the treatment of citrus fruit, in particular orange, lemon, grapefruit, mandarin. Particularly preferred is the treatment of tropical fruit, in particular papaya, passion fruit, mango, carambola, pineapple, banana.Particularly preferred is the treatment of grapevines.

The active compound combinations or compositions according to the invention can be used as such or, depend ing on their respective physical and/or chemical properties, in the form of their formulations or the use forms prepared therefrom, such as aerosols, capsule suspensions, cold-fogging concentrates, warm-fogging concentrates, encapsulated granules, fine granules, flowable concentrates for the treatment of seed, ready-to-use solutions, dustable powders, emulsifiable concentrates, oil-in-water emulsions, water-in-oil emulsions, macrogranules, microgranules, oil-dispersible powders, oil-miscible flowable concentrates, oil- miscible liquids, foams, pastes, pesticide-coated seed, suspension concentrates, suspo emulsion concentrates, soluble concentrates, suspensions, wettable powders, soluble powders, dusts and granules, water-soluble granules or tablets, water-soluble powders for the treatment of seed, wettable powders, natural products and synthetic substances impregnated with active compound, and also micro encapsulations in polymeric substances and in coating materials for seed, seedling and harvested product and also ULV cold-fogging and warm-fogging formulations.

The active compound combinations according to the invention can be present in (commercial) formulations and in the use forms prepared from these formulations as a mixture with other (known) active compounds, such as insecticides, attractants, sterilants, bactericides, acaricides, nematicides, fungicides, growth regulators, herbicides, fertilizers, safeners and Semiochemicals.

The treatment according to the invention of the plants, plant edible parts, fruit leaves with the active compounds or compositions is carried out directly or by action on their surroundings, habitat or storage space using customary treatment methods, for example by dipping, spraying, atomizing, irrigating, evaporating, dusting, fogging, broadcasting, foaming, painting, spreading-on, watering (drenching), drip irrigating and, in the case of propagation material, in particular in the case of seeds, furthermore as a powder for dry seed treatment a solution for seed treatment, a water-soluble powder for slurry treatment, by incrusting, by coating with one or more layers, etc. It is furthermore possible to apply the active compounds by the ultra-low volume method, or to inject the active compound preparation or the active compound itself into the soil.

The present invention is directed to the use of combinations of oligo(2-(2- cthoxyjcthoxy ethyl guanidinium chloride), poly(hexamethylendiamine guanidinium chloride), polyetheramines, triethyleneglycol diamine, enzymes, PGPR, amino acids, antioxidants such as humic acids and some natural products like phytotherapeutic plant extracts as antibacterial agent against the gram negative bacterial and fungie pathogens combinations of oligo(2-(2-ethoxy)ethoxy ethyl guanidinium chloride), poly(hexamethylendiamine guanidinium chloride), polyetheramines, triethyleneglycol diamine, enzymes, PGPR, amino acids, antioxidants such as humic acids and some natural products like phytotherapeutic plant extracts in refrigerated foods or refrigerated drinks with the proviso that in addition to said guanidium and/or guanidium derivative no hetero -saccharide containing macromolecule is used, nor l,5-D-anhydrofructose is used as antibacterial agent in said foods. While in some the prior art documents complicated guanidium compounds are mentioned which are stated to have antibacterial properties, the present invention is directed to the use of "simple" guanidium compounds such as combinations of oligo(2-(2-ethoxy)ethoxy ethyl guanidinium chloride), poly(hexamethylendiamine guanidinium chloride), polyetheramines, triethyleneglycol diamine, enzymes, PGPR, amino acids, antioxidants such as humic acids and some natural products like phytotherapeutic plant extracts. The medium present in real food and food products products comprises proteins and fats, has a specific mobility of the liquids present, adsorption or incorporation of the guanidium in the food product may occur. Without being committed to a theory, it is thought that the fact that guannidium is an amin group and a natural building block of food and food products and is abundantly present in food constituents, causes it to interfere in a rather unpredictable way in real food and food products. We have found that combinations of oligo(2-(2-ethoxy)ethoxy ethyl guanidinium chloride), poly(hexamethylendiamine guanidinium chloride), polyetheramines, triethyleneglycol diamine, enzymes, PGPR, amino acids, antioxidants such as humic acids and some natural products like phytotherapeutic plant extracts can effectively be used as a sole antibacterial agent in concentrations that are still acceptable in food and food products without negatively affecting the product quality with respect to for example taste and texture. We have found that combinations of oligo(2-(2-ethoxy)ethoxy ethyl guanidinium chloride), poly(hexamethylendiamine guanidinium chloride), polyetheramines, triethyleneglycol diamine, enzymes, PGPR, amino acids, antioxidants such as humic acids and some natural products like phytotherapeutic plant extracts can be used as sole antibacterial agent for preservation purposes and further to prevent the consequences of contamination of food and drink products as food poisoning by pathogenic bacteria due to temperature-abuse and/or contamination. It is not needed to add an auxiliary antibacterial agent to achieve the desired preservation effect in contrast to the results described in above-mentioned patents. This results not only in lower material costs but also in a higher product quality. Products are obtained with less auxiliary ingredients added while maintaining and even improving the quality and shelf life of said products. Further, this is in line with legislation that is aimed at minimisation of the use of additives in food applications. Furthermore, the products obtained are also protected against the consequences of temperature-abuse or contamination.

Combinations of oligo(2-(2-ethoxy)ethoxy ethyl guanidinium chloride), poly(hexamethylendiamine guanidinium chloride), polyetheramines, triethyleneglycol diamine, enzymes, PGPR, amino acids, antioxidants such as humic acids and some natural products like phytotherapeutic plant extracts concentrations of 0.2 to 3 wt% based on total weight of product show antibacterial activity against Salmonella, and in particular Salmonella typhimurium and Salmonella enteriditis. combinations of oligo(2-(2-ethoxy)ethoxy ethyl guanidinium chloride), poly(hexamethylendiamine guanidinium chloride), polyetheramines, triethyleneglycol diamine, enzymes, PGPR, amino acids, antioxidants such as humic acids and some natural products like phytotherapeutic plant extracts concentrations of 0.2 to 1.5 wt% based on total weight of product were found to be suited in ensuring taste of the product. Tests showed that a concentration of about 1 to 1.8 wt% of combinations of oligo(2-(2-ethoxy)ethoxy ethyl guanidinium chloride), poly(hexamethylendiamine guanidinium chloride), polyetheramines, triethyleneglycol diamine, enzymes, PGPR, amino acids, antioxidants such as humic acids and some natural products like phytotherapeutic plant extracts based on total weight of product starts to affect the taste of said product. In said product no auxiliary antibacterial agents and no other taste affecting ingredients were present. A combinations of oligo(2-(2-ethoxy)ethoxy ethyl guanidinium chloride), poly(hexamethylendiamine guanidinium chloride), polyetheramines, triethyleneglycol diamine, enzymes, PGPR, amino acids, antioxidants such as humic acids and some natural products like phytotherapeutic plant extracts concentration above 1.5 wt% based on total weight of the product gives the product a sweet taste. Dependent on the type of product this sweet taste is acceptable or not. In sweet drinks for example the sweetening effect of guanidium is not considered a problem. Accordingly the maximally acceptable combinations of oligo(2-(2-ethoxy)ethoxy ethyl guanidinium chloride), poly(hexamethylendiamine guanidinium chloride), polyetheramines, triethyleneglycol diamine, enzymes, PGPR, amino acids, antioxidants such as humic acids and some natural products like phytotherapeutic plant extracts concentration in terms of not negatively affecting taste can be increased to concentrations above 1.8 wt% guanidium based on total weight of the product. Further, dependent on the presence of other taste affecting ingredients in the product as for example masking agents, the maximum concentration of combinations of oligo(2-(2-ethoxy)ethoxy ethyl guanidinium chloride), poly(hexamethylendiamine guanidinium chloride), polyetheramines, triethyleneglycol diamine, enzymes, PGPR, amino acids, antioxidants such as humic acids and some natural products like phytotherapeutic plant extracts can also be increased up to a point at which the taste starts to be negatively affected by the presence of gundium derivative. It was found that the use of guanidium and/or its derivatives according to the invention as antibacterial agent in refrigerated foods and refrigerated drinks may be combined with one or more combinations of oligo(2-(2-ethoxy)ethoxy ethyl guanidinium chloride), poly(hexamethylendiamine guanidinium chloride), polyetheramines, triethyleneglycol diamine, enzymes, PGPR, amino acids, antioxidants such as humic acids and some natural products like phytotherapeutic plant extracts.

SUMMARY OF THE INVENTION

The present invention provides protecting agent a combination guanidinium derivatives, particularly to combinations of oligo(2-(2-ethoxy)ethoxy ethyl guanidinium chloride), poly(hexamethylendiamine guanidinium chloride), enzymes, PGPR, amino acids, antioxidants like humic acids and some natural products like phyto therapeutic plant extracts.

The present invention is based in part on the unexpected discovery that oligo (2- (2-ethoxy) ethoxy ethyl guanidinium chloride), poly(hexamethylendiamine guanidiniumchloride), enzymes, PGPR, amino acids, antioxidants like humic acids and some natural products like phytotherapeutic plant extracts show a synergistic inhibiting effect on the proliferation of various cancerous cell types. Without wishing to be bound by any particular theory or mechanism of action this synergistic effect may be attributed to the capability of oligo (2-(2-ethoxy) ethoxy ethyl guanidinium chloride), poly(hexamethylendiamine guanidinium chloride), enzymes, PGPR, amino acids, antioxidants like humic acids and some natural products like phytotherapeutic plant extracts to significantly enhance the therapeutic effect. The present invention is a food enhancer which curbs one's appetite while simultaneously adding nutritional value and flavor to the food to be eaten. The composition is in powder form that is versatile in application to any food. The food protecting composition can be added to food being cooked, included in appetizers or sprinkled on any food while eating out. It consists of a variety of beans, grains, vitamins, herbs, and spices. Because the food enhancer is taken in powder form, absorption by the body is maximized and it is easier to swallow as opposed to tablets. This composition is intended to replace salt, pepper and other spices.

It is another object of the invention to provide a food protecting materila in powder form in addition to liquid form.

DETAILED DESCRIPTION OF THE INVENTION

The present invention relates to methods for the protection of harvested fruits, cutflowers or vegetables against decay caused by certain storage diseases or disorders expressed in storage conditions, which fruits, cutflowers or vegetables have been treated pre -harvest with combinations of oligo(2-(2-ethoxy)ethoxy ethyl guanidinium chloride), poly(hexamethylendiamine guanidinium chloride), polyetheramines, triethyleneglycol diamine, enzymes, PGPR, amino acids, antioxidants such as humic acids and some natural products like phytotherapeutic plant extracts.

Food protecting agent composition having a pH of between 5.5 and 7.5 containing at least 2000 mg/l, preferably at least 1800 mg/l of a combination food protecting agent and guanidinium derivatives, particularly to combinations of oligo(2-(2- ethoxy)ethoxy ethyl guanidinium chloride), poly(hexamethylendiamine guanidinium chloride), polyetheramines, triethyleneglycol diamine, enzymes, PGPR, amino acids, antioxidants such as humic acids and some natural products like phytotherapeutic plant extracts.

The purpose of any pre -harvest plant protection program for fruit, cutflowers and vegetables is to prevent the development of diseases that might impair the final quality of the fruit, cutflowers and vegetables and to obtain adequate production yields. The system for post-harvest application of plant protection products on fruit, cutflowers and vegetables during packing aims to safeguard the health of the fruit and vegetables during the period of storage and transport to the final consumer. Since, moreover, the environmental and economic requirements imposed on modem-day fungicides are continually increasing, with regard, for example, to the spectrum of activity, toxicity, selectivity, application rate, formation of residues, and favorable preparation ability, and since, furthermore, there may be problems, for example, with resistances developing to known active compounds, a constant task is to develop new fungicide agents which in some areas at least have advantages over their known counterparts. Therefore, there is still a need to find and/or develop other bacterial, viral and fungicides for storage disease control. Some of the chemical as such are already known. It is also known, that these compounds can be used as more helaty and appliceable material.

This invention relates to the use of an antibacterial agent against gram-negative bacterial pathogens in foods. Further, said antibacterial agent is in particular used against bacteria and bacteria from the genus Fusarium spp., e.g. Fusarium semitectum, Fusarium moniliforme, Fusarium solani, Fusarium oxysporum; Verti- cillium spp., e.g. Verticillium theobromae; Nigrospora spp.; Botrytis spp., e.g. Botrytis cinerea; Geotrichum spp., e.g. Geotrichum candidum; Phomopsis spp., Phomopsis natalensis; Diplodia spp., e.g. Diplodia citri; Alternaria spp., e.g. Altemaria citri, Alternaria altemata; Phytophthora spp., e.g. Phytophthora citrophthora, Phytophthora fragariae, Phytophthora cactorum, Phytophthora parasitica; Septoria spp., e.g. Septoria depressa; Mucor spp., e.g. Mucor piriformis; Monilinia spp., e.g. Monilinia fructigena, Monilinia laxa; Venturia spp., e.g. Venturia inaequalis, Venturia pyrina; Rhizopus spp., e.g. Rhizopus stolonifer, Rhizopus oryzae; Glomerella spp., e.g. Glomerella cingulata; Sclerotinia spp., e.g. Sclerotinia fruiticola; Ceratocystis spp., e.g. Ceratocystis paradoxa; Penicillium spp., e.g. Penicillium funiculosum, Penicillium expansum, Penicillium digitatum, Penicillium italicum; Gloeosporium spp., e.g. Gloeosporium album, Gloeosporium perennans, Gloeosporium fructi genum, Gloeosporium singulata; Phlyctaena spp., e.g. Phlyctaena vagabunda; Cylindrocarpon spp., e.g. Cylin drocarpon mali; Stemphyllium spp., e.g. Stemphyllium vesicarium; Phacydiopycnis spp., e.g. Phacydiopycnis malirum; Thielaviopsis spp., e.g. Thielaviopsis paradoxy; Aspergillus spp., e.g. Aspergillus niger, Aspergillus carbonarius; Nectria spp., e.g. Nectria galligena; Pezicula spp., Escherichia Coli, Enterobacter sakazakii, Salmonella, pseudomonas, escheria coli, entereobacter aerogenes, coliform, legionalla, and Campylobacter in food. Conventionally, bacterial growth in food is controlled and/or prevented by means of pH regulation, water activity control, addition of quality preserving agents as e.g. nitrite and/or using various processing techniques as for example heat treatment, irradiation or high-pressure treatment. However, when controlling gram negative bacterial pathogens the above-described measures are often either insufficient, undesirable or not suitable for the type of food. For instance, controlling the water activity in products is possible by means of e.g. salt addition. Controlling or preventing bacterial growth in products by means of salt addition however requires high salt concentrations. Some of the study result shows that high concentrations often lead to a loss of taste because the product becomes too salty and not applicable. Further, a too high salt dosage is also not desired with respect to health issues as for example heart and vascular diseases or blood pressure. Furthermore, in protein-containing products as for example mushroom said high salt concentrations may lead to deterioration of the texture of the product. As gram-negative bacterial pathogens and some fungie such as Fusarium semitectum, Fusarium moniliforme, Fusarium solani, Fusarium oxysporum; Verti- cillium spp., e.g. Verticillium theobromae; Nigrospora spp.; Botrytis spp., e.g. Botrytis cinerea; Geotrichum spp., e.g. Geotrichum candidum; Phomopsis spp., Phomopsis natalensis; Diplodia spp., e.g. Diplodia citri; Alternaria spp., e.g. Altemaria citri, Alternaria altemata; Phytophthora spp., e.g. Phytophthora citrophthora, Phytophthora fragariae, Phytophthora cactorum, Phytophthora parasitica; Septoria spp., e.g. Septoria depressa; Mucor spp., e.g. Mucor piriformis; Monilinia spp., e.g. Monilinia fructigena, Monilinia laxa; Venturia spp., e.g. Venturia inaequalis, Venturia pyrina; Rhizopus spp., e.g. Rhizopus stolonifer, Rhizopus oryzae; Glomerella spp., e.g. Glomerella cingulata; Sclerotinia spp., e.g. Sclerotinia fruiticola; Ceratocystis spp., e.g. Ceratocystis paradoxa; Penicillium spp., e.g. Penicillium funiculosum, Penicillium expansum, Penicillium digitatum, Penicillium italicum; Gloeosporium spp., e.g. Gloeosporium album, Gloeosporium perennans, Gloeosporium fructi genum, Gloeosporium singulata; Phlyctaena spp., e.g. Phlyctaena vagabunda; Cylindrocarpon spp., e.g. Cylin drocarpon mali; Stemphyllium spp., e.g. Stemphyllium vesicarium; Phacydiopycnis spp., e.g. Phacydiopycnis malirum; Thielaviopsis spp., e.g. Thielaviopsis paradoxy; Aspergillus spp., e.g. Aspergillus niger, Aspergillus carbonarius; Nectria spp., e.g. Nectria galligena; Pezicula spp., Escherichia Coli, Enterobacter sakazakii, Salmonella, pseudomonas, escheria coli, entereobacter aerogenes, coliform, legionalla, and Campylobacter are notoriously present in protein-containing products such as mushroom, cheese etcetera, controlling the water activity is often not a viable solution. Also pH regulation of the pH as means for controlling bacterial growth can cause loss of taste of the product and/or loss of texture of the product, especially in protein-rich food. Furthermore, some gram-negative pathogenic bacteria are relatively insensitive to acid addition. For instance growth of Campylobacter bacteria and Salmonella bacteria can be stopped at a pH lower than respectively 4.0 and 3.8, which pH is for some food applications undesirable because of its effect on taste, texture and not convenient appliceable methods.

Nitrite is added in cured meat (including poultry and fish) applications for the purpose of preserving product quality. Nitrite is able to stop bacterial growth of some types of bacteria as for example Clostridium. In some cases nitrite is added as colouring agent to maintain a certain colour in the meat product. Due to this colouring effect of nitrite it is not desirable for all meat applications. Examples of uncured, not nitrite-containing, product applications are (German) sausages, chicken and turkey meat and roast beef. As mentioned above, especially gram negative bacterial pathogens are often present in these food products. At present legislation is aimed at minimisation of the use of nitrite in food applications. It goes without saying that processing techniques as for example heat treatment, irradiation or high-pressure treatment as method for preservation of products is not always applicable to food applications such as salads and other vegetable products due to processing spreed, costs, consumer preference and influence on the texture and/or taste.

Thus, said above-mentioned methods of salt addition, pH regulation, nitrite addition and processing techniques as e.g. heat treatment are not always satisfactory for the purpose of preservation of foods, especially when controlling gram-negative bacterial pathogens. Accordingly, the preservation of protein- containing food products, pH sensitive food products and refrigerated food products such salads and other vegetable products, dried foods and convenient foods as e.g. ready-to-eat meals, and especially mushroom products still proves to be a problem, especially if the food product needs to be protected against food poisoning as consequences of e.g. temperature-abuse and/or contamination of food. It is known that one of the most important causes of food poisoning is contamination due to incorrect handling of food products. Furthermore, products are often stored at improper conditions. Temperature-abuse (e.g. incidental storage at high temperature) can cause the in the product already present but inactivated bacteria to grow again resulting in food poisoning by pathogenic bacteria. The invention provides an effective alternative to overcome the above- mentioned problems in preservation of foods against food poisoning and further provides a means for fighting food poisoning by pathogenic bacteria of food and products due to e.g. temperature-abuse and/or contamination due to e.g. improper handling and/or improper preparation. It is known that combinations of oligo(2- (2-ethoxy)ethoxy ethyl guanidinium chloride), poly(hexamethylendiamine guanidinium chloride), polyetheramines, triethyleneglycol diamine, enzymes, PGPR, amino acids, antioxidants such as humic acids and some natural products like phytotherapeutic plant extracts can be used to prevent growth of bacteria which cause food spoilage, also called putrefaction. Normally these are lactic acid bacteria, i.e. gram-positive bacteria. When food is spoiled, the taste and/or its appearance is affected, but the consumers health is not at stake. The present invention, however, is directed to the prevention of food poisoning. Food poisoning is caused by gram-negative bacterial pathogens and fungie such as Fusarium semitectum, Fusarium moniliforme, Fusarium solani, Fusarium oxysporum; Verticillium spp., e.g. Verticillium theobromae; Nigrospora spp.; Botrytis spp., e.g. Botrytis cinerea; Geotrichum spp., e.g. Geotrichum candidum; Phomopsis spp., Phomopsis natalensis; Diplodia spp., e.g. Diplodia citri; Altemaria spp., e.g. Alternaria citri, Altemaria altemata; Phytophthora spp., e.g. Phytophthora citrophthora, Phytophthora fragariae, Phytophthora cactorum, Phytophthora parasitica; Septoria spp., e.g. Septoria depressa; Mucor spp., e.g. Mucor piriformis; Monilinia spp., e.g. Monilinia fructigena, Monilinia laxa; Venturia spp., e.g. Venturia inaequalis, Venturia pyrina; Rhizopus spp., e.g. Rhizopus stolonifer, Rhizopus oryzae; Glomerella spp., e.g. Glomerella cingulata; Sclerotinia spp., e.g. Sclerotinia fruiticola; Ceratocystis spp., e.g. Ceratocystis paradoxa; Penicillium spp., e.g. Penicillium funiculosum, Penicillium expansum, Penicillium digitatum, Penicillium italicum; Gloeosporium spp., e.g. Gloeosporium album, Gloeosporium perennans, Gloeosporium fructi genum, Gloeosporium singulata; Phlyctaena spp., e.g. Phlyctaena vagabunda; Cylindrocarpon spp., e.g. Cylin drocarpon mali; Stemphyllium spp., e.g. Stemphyllium vesicarium; Phacydiopycnis spp., e.g. Phacydiopycnis malirum; Thielaviopsis spp., e.g. Thielaviopsis paradoxy; Aspergillus spp., e.g. Aspergillus niger, Aspergillus carbonarius; Nectria spp., e.g. Nectria galligena; Pezicula spp., Escherichia Coli, Enterobacter sakazakii, Salmonella, pseudomonas, escheria coli, entereobacter aerogenes, coliform, legionalla, and Campylobacter was said that pathogens produce toxine and/or cause infections.
