Definitions
- the present invention generally relates to the field of conservation and transformation of algae for use in particular in human food or animal or plant food or in cosmetics.
- marine algae can be suitable for the invention.
- Gracilaria verrucosa Chondrus crispus, Himanthalia elongata commonly called sea beans
- Laminaria saccarina Laminaria digitata
- Undaria pinnatifida Palmaria palmata
- Ulva lactuca commonly called sea lettuce
- Ulva armoricana Ulva intestinalis
- Solieria Chordalis Porphyra umbilicalis
- Lucus visiculosus Ascophyllum nodosum
- Saccharina Japonica commonly known as kombu algae, Sargassum, Macrocystis pyrifera, Asparagopsis taxiformis, Alaria esculenta, Alaria marginata, commonly known as wakame.
- algae are already recognized for food in general, both human and animal, or for cosmetics and for the treatment of plants.
- algae are already harvested and consumed by humans and animals throughout the world and are also used as soil conditioners, for example in the form of seaweed.
- marine algae are already sought after and exploited for their very high nutritional value in vitamins, proteins, trace elements, omega 3 and 6 fatty acids beneficial for health, etc.
- Algae as a vegetable has been authorized for consumption in France since the early 1980s. Only a limited number of varieties of “vegetable” algae benefit from this authorization. Their sale is subject to strict regulatory requirements, mainly concerning their heavy metal and iodine content.
- Food algae are currently mainly stabilized by brining or drying.
- Silage or lactofermentation is a traditional process in vegetables which can therefore be applied to algae and thus aims to preserve them over long periods while providing organoleptic (texture, taste) and nutritional benefits.
- the aim of the invention is to respond at least in part to these need(s).
- the invention relates to a process for transforming algae comprising the following steps: i) supply of algae harvested in an aquatic environment, where appropriate frozen; ii) washing with water the algae supplied according to step i); iii) optionally, cutting or grinding the washed algae according to step ii); iv) optionally, supply of an inoculum comprising mainly bacteria producing lactic acid; v) either seeding the algae optionally cut or crushed according to step iii) with the inoculum provided according to step iv) which comprises a concentration of lactic acid bacteria sufficient for the growth of the bacteria present in the algae so as to carry out their lactofermentation, i.e.
- the algae provided in step i) are preferably marine algae chosen from one of the following species: Gracilaria verrucosa, Chondrus crispus, Himanthalia elongata commonly known as sea beans, Laminaria digitata commonly known as Breton kombu algae, Undaria pinnatifida, Palmaria palmata, Ulva lactuca commonly known as sea lettuce, Ulva armoricana, Ulva intestinalis, Solieria Chordalis, Porphyra umbilicalis, Fucus visiculosus, Ascophyllum nodosum, Saccharina Japonica, commonly known as kombu seaweed, Saccharina latissima, commonly known as Kombu royal seaweed, , Sargassum,, Macrocystis pyrifera, Asparagopsis taxiformis, Undaria pinnatifida, Alaria esculenta, Alaria marginata, commonly called wakame or a combination of them.
- Washing step ii) is advantageously carried out by soaking and bubbling.
- This improved washing should be considered particularly for stranded algae, that is to say which have been detached/torn from their natural support and which are collected when they are washed up on a beach in particular. This allows you to get rid of unwanted items (sand, stones, plastic waste, etc.). For hand-harvested algae, simple cleaning with water may be sufficient.
- Step iii) is advantageously carried out so that the length of the cut algae is between 0.2 and 5 cm.
- grinding increases the contact surface between the algae and the ferments and therefore promotes the fermentation of the algae.
- the lactic acid bacteria are preferably chosen from one of the following species: Lactobacillus plantarum, Leuconostoc mesenteroides, Lactobacillus lactis, Lactobacillus zeae, Lactobacillus casei or paracasei, Lactobacillus harbinensis, Leuconostoc kimch, Lactobacillus delbruecki, Lactobacillus rhamnosus, Lactobacillus harbinensis, Streptococcus thermophilus, Propionibacterium or a combination of these.
- the process comprises before the seeding step v) conditioning the cut or crushed algae in a storage tank followed by their anaerobiosis.
- step vi) of collection is carried out by drawing off the lactofermented juice.
- the process comprises, once the addition of liquid has been made and before withdrawal, a maceration step for a period of between 1 and 20 days, preferably between 1 and 15 days.
- the invention also relates to the use of lactofermented algae collected in step vii) of the process as described above, for human food.
- the invention also relates to the use of the lactofermented juice collected in step vi) of the process as described above, where appropriate mixed with lactofermented algae collected in step vii) of the process as described previously as as a phytostimulant for plant production and/or to improve soil quality.
- lactofermented juice or a mixture with lactofermented algae can be used to spread soil or spray directly onto soil.
- the invention also relates to the use of the lactofermented juice collected in step vi) of the process as described above, in pharmacology.
- the invention essentially consists of a lactofermentation process for fresh algae which can be natural or with seeding with PH control and advantageously anaerobic and which makes it possible to concomitantly produce algae ready to be consumed in the form of vegetables. and a fermentation juice that can be drunk directly by animals or mixed with animal feed. Once the PH is stabilized, the algae and the fermented juice obtained are separated.
- Lactofermentation can be natural or require seeding depending on the type of algae.
- Seeding can be implemented to accelerate or trigger natural lactofermentation.
- the algae can be cut or ground.
- a cutout makes it possible to increase the fermentation contact surface between algae and ferments.
- co-products are systematically and directly obtained, that is to say algae in lactofermented plant form ready to be consumed and a juice in particular which can be consumed directly by animals.
- these co-products can be mixed once collected for direct use in human, plant or animal nutrition.
- the results of obtaining the food qualities of algae and juices are highly reproducible for a very large number of varieties of algae, particularly marine algae.
- FIG IA [Fig IB] Figures IA and IB show a synopsis of the essential steps of an algae lactofermentation process according to the invention.
- Figure 2 illustrates in longitudinal section view an example of a fermentation tank implemented in the lactofermentation process according to the invention.
- FIGs 3 and 4 illustrate in the form of a curve the monitoring of the fermentation pH of an example of algae, respectively Himanthalia elongata and Saccharina during a process according to the invention.
- an installation can be implemented continuously in the process according to the invention, that is to say at the inlet of the process from a feed hopper into which the discharge of fresh algae is carried out until the tank/container for storing and collecting lactofermented algae and fermented juice, obtained at the end of the process.
- one or more conveying devices in particular with belts, can be arranged in the installation between two stations carrying out distinct stages of the process.
- Marine algae arrives fresh and unrinsed into the facility, directly from where it was harvested in the marine environment.
- One of the advantages inherent to the process is that their Prior transport does not need to be carried out with a refrigerated vehicle. Obviously, they can still be frozen at the start of the process, particularly if they have been harvested for a certain time before implementing the process according to the invention.
- a ginning step i) can be carried out within a gin which can be standard. This ginning makes it possible to regulate the feed rate of an algae cutting machine used afterwards and to carry out, if necessary, a visual sorting of undesirable elements, such as parasitic algae, shellfish possibly present in the algae such as periwinkles. or others.
- This washing which consists of rinsing with fresh water, eliminates any traces of sand within the algae.
- this washing can be carried out within the gin itself. cuts the algae to a calibrated length.
- a conveyor belt with a low slope can be used to pour the algae and feed it directly into the machine. This prevents the algae leaving the gin from clumping/agglutinating, that is to say, mixing themselves by becoming denser, which can harm the quality (homogeneity, precision) of the cutting.
- the cutting length made is carefully chosen depending on the type of algae to be fermented.
- the cutting carried out makes it possible to increase the contact surface between the algae and the lactic ferments used while retaining the morphological properties of the algae that we wish to have for their qualities as food.
- the cut algae are conveyed inside at least one tank or container which serves as a place of storage, seeding and collection.
- This container 1 comprises a tank 10 internally delimiting the volume in which a mixture M of cut algae and water, then with ferments as according to the subsequent stage of lactofermentation, is stored.
- the container 10 can be a rigid plastic box with side walls and a waterproof bottom, such as that marketed under the trade name Geobox®.
- the volume of the mixture present in tank 10 is topped by a plate 2 which forms ballast on the free surface.
- This plate 2 is advantageously made of a non-oxidizing material.
- the tank 10 is preferably filled with water to approximately 20 to 40% of the weight of the stored algae.
- the ballast plate 2 also forms a sealing layer which prevents surface oxidation.
- the tank 10 is preferably closed in a sealed manner above the plate 2 by a cover 3.
- a waterproof film can be placed on the cover 3 to limit gas exchange with the outside.
- a tap 4 is arranged at the bottom of the tank 10 for withdrawing the lactofermented juice at the end of the process by gravity or by pumping.
- the ferments are diluted in physiological water for 30 min at 20/25°C to rehydrate them and to obtain adequate distribution.
- the inoculum is dosed to have a concentration of lactic acid bacteria sufficient for the growth of the bacteria present in the algae so as to achieve their lactofermentation.
- the seeding rate is between 10 5 and 10 7 CFU/g.
- a particularly suitable strain is Lactobacilus Plantarum at a seeding rate of 10 6 CFU/g.
- the mixture M in a given container contains algae cut from the rehydrated ferments according to step iv) and a salt preferably in a proportion of 1 to 3% by weight of the algae and non-chlorinated fresh water preferably in a proportion of 10 to 100% of the weight of the algae.
- This seeding step can take place very quickly after harvesting the fresh algae, typically between 24 and 48 hours after harvest.
- the lactofermentation is regularly monitored and is continued until the measured pH of the lactofermented composition has fallen below a predetermined final threshold.
- this pH should be less than 4.5, preferably less than 4.2. Beyond a pH of approximately 4.2, 4.3, there may be risks of pathogenic bacteria and, where applicable, unrevealed palatability qualities.
- Figure 3 illustrates the evolution of the pH of a mixture with algae of the Himanthalia elongata species, cut to a length between 0.5 and 1.3cm.
- the lactofermentation time according to the invention is considered to be completed when the pH is stabilized below a threshold, in order to be able to offer the algae as food products.
- the process can be optimized to lower and stabilize the pH more quickly for the same species of algae.
- the lactofermentation time which is necessary also depends on the texture of the algae which we wish to give them for their subsequent consumption.
- Table 1 below brings together the feedback from experiments made by the inventor on the texture for two species of algae, over time.
- the fermentation juice is drawn off for a volume of between 5 and 40% of the total volume of the mixture M.
- this withdrawn volume is replaced by a substantially identical volume of water whose pH remains at the predetermined threshold.
- the lactofermented, drawn-off juice is filtered so as to retain the organic elements in suspension.
- a standard stainless steel filter with a very fine mesh typically between 0.5 and 0.8mm.
- Step vi2) Then we proceed to packaging the filtered juice. This can be done in small volume cans or buckets, typically 20 L or larger volume barrels typically 220 L.
- the juice can also be packaged in IBC type tanks (Anglo-Saxon acronym for "Intermediate”).
- Bulk Container which are tank containers of large unit volume, typically 1000L, and which are usually used for the storage and transport of liquids.
- the storage period can go up to a use-by date (DLC) within 6 months at room temperature, for tests carried out on the species of algae tested.
- DLC use-by date
- the juice collected and stored can be directly or indirectly used for animal, plant or human use.
- the inventor carried out tests on the juice obtained for different species of algae.
- Lactofermented algae and juice obtained from Himanthalia elongata (sea beans),
- salting was carried out in a quantity of 1 to 10% relative to the weight of the cut algae.
- the cut and salted algae were stored at a temperature between 10 and 30°C in closed tanks and individually weighted by a plate whose weight is of the order of 10% of the weight of the algae contained in a tank.
- the inventor carried out other complementary tests.
- the lactofermented algae collected and therefore separated from the juice were pressed and dried in a dryer.
- This drying can be carried out at a temperature range of 40°C to 100°C
- the dried algae were then crushed/micronized to obtain lactofermented algae powders with effective functional and nutritional properties.
- This natural biodegradable absorbent consisting of dried and micronized algae can represent an interesting plant-based alternative to food additives (Carboxymethylcellulose (E466) Sodium alginate (E401) Pectin (E440) Gum arabic (E414) Guar gum (E412) Modified starch (E1404 , E1412, E1414) Carrageenan (E407) Alginic acid (E400)
- Food additives Carboxymethylcellulose (E466) Sodium alginate (E401) Pectin (E440) Gum arabic (E414) Guar gum (E412) Modified starch (E1404 , E1412, E1414) Carrageenan (E407) Alginic acid (E400)
- the container serves both for the stages of storing the algae before sowing, as a place for lactofermentation, and for collection, we can consider having one or more storage tanks for the algae before their sowing, a or several other tanks for lactofermentation and for collecting lactofermented algae and juice.
- IBC type tanks can be used, in a version equipped with a valve or tap for drawing off the lactofermented juice by gravity or pumping.
- the example shown above is for Himanthalia elongata with seeding.
- Figure 4 illustrates in the form of a curve the monitoring of the exclusively natural fermentation pH of a Kombu Royal during a process which has just been described.
- the separation of the juice and the algae is also carried out after checking the stabilized pH of the juice below 3.2.
- Color, odor and viscosity are also indicators of the maturity of this algae stored in fermentation.
- an open tank can be used for oxygenation and, if necessary, stirring with a bubbler arranged within the fermentation mixture volume.
- sea water or fresh salt water at 3.5% can be used.
- fresh water is preferred to obtain an osmotic shock and tenderize the sea lettuce to promote the action of lactic acid bacteria and thus dissolve the algae with little or no production of PhS gas.
- Ulva lactuca the inventor tested Lactobacillus Harbinensis and Leuconostoc Kimchi as strains which seem promising.
- the separation of the juice and the algae is carried out after checking the stabilized pH of the juice below 4.2. Color, odor and viscosity are also indicators of the maturity of this algae stored in fermentation.
- Ulva lactuca the inventor plans to mix the algae and the juice obtained to form a nutritional purée.
- lactofermented juice and algae different equipment can be tested and implemented to optimize the extraction, separation and concentration of the co-products obtained (lactofermented juice and algae).
- juices can be concentrated and/or filtered by various mechanical systems (atomization, ultrafiltration, centrifugal, tangential, etc.).
- the choice of system is preferably made according to the degree of transformation of the assets that we wish to obtain.
- the active ingredients present in lactofermented juices vary depending on the varieties and strains of ferments used. Furthermore, we can consider adding enzymes, particularly when the variety of algae makes it difficult to seed bacteria or fermentation strains.
- endoglucanases and pectinases can be added for the transformation of green algae: through their rapid action, these enzymes can release the elements necessary for lactic acid bacteria and initiate fermentation without producing hydrogen sulphide (FhS). ). Enzymes with specific actions can also be considered to improve the quality of lactofermented juices. For example, these specific enzymes can lower the heavy metal load of juices.
- the inventor carried out tests by mixing 30% of lacto-fermented sea beans obtained according to the process of the invention, with ground beef in order to obtain a steak.
- the inventor also carried out tests by mixing lacto-fermented sea beans obtained according to the process of the invention, with sausage meat.
- B/ animal feed in particular sheep, bovine or porcine or poultry:
- lactofermented algae obtained according to the process of the invention can be used as a nutritional raw material, aromatic, texturizing or absorbent factor.
- lactofermented algae can be mixed into cattle feed, to improve the balance of their microbiota and the performance of their digestive metabolism and therefore to improve the quantity and quality of the milk they produce.
- lactofermented algae obtained according to the process of the invention in doses of medication, particularly in boluses: in fact, the texturizing and nutritional qualities of the algae can improve the effects of the medication on the animal. .
- the inventor has carried out encouraging tests, mixing lactofermented algae collected according to the process of the invention to obtain an optimal density of substrates for insect larvae.
- the inventor believes that a mixture of a lactofermented juice obtained according to the invention in a sports drink can make it possible to increase the intake of metabolites.
- Another use envisaged for a lactofermented juice obtained according to the invention is the hydration of poultry while avoiding the formation of biofilm in liquid feeding systems, due to the antibacterial properties of the juice.
