Definitions

an active packaging for transportation and storage of plants on growing substratum and/or of leafy branches and/or of cut flowers and/or of vegetative material for reproduction comprising an adsorbent material made of cellulose, zeolites and starch in an amount of 0,06 - 0.5% by weight, with reference to the overall weight of the active packaging, and a semipermeable film characterized by the following characteristics.
the semipermeable film is thermally welded in order to improve the isolation of the plants and/or of the leafy branches, or of the cut flowers inside said packaging.
the active packaging is formed by an adsorbent material, that is put preferably under the vase of the plant and/or of the stem of the flower, and by a semipermeable film, advantageously sealed in hermetic way.
the choice of the film and the weight of adsorbent material inside the packaging is calculated in function of the typology of the confectioned plant and in function of its respiratory rate and that of transpiration.
the weight of the adsorbing material inserted into the packaging varies between 0,06 and 0.5%.
the adsorbent used in the present invention has been described in European patent application, publication N. 1530998 for use in packaging for alimentary products.
it contains cellulose in an amount of 40-85%, zeolites in an amount 2-30% and starch in an amount of 0,1% to the amount complementary to 100%, said amounts being expressed as amounts by weight with reference to the overall weight of the mixture.
it can also contain kaolin and/or rubber in a percentage of weight of 0,1-0,3%, with reference to the overall weight of adsorbent.
the cellulose used for the production of adsorbent according to the present invention is preferably a mixture of long fibre cellulose and microcrystalline cellulose in ratio from 70 to 30% to 50 to 50%, in particularly preferred way from 60 to 40%.
the used zeolites are preferably present as mixture of 3A and 4A zeolites, in ratio between 80 and 20% and 60 and 40%, preferably between 70 and 30%.
the used starch which must render the mixture more compact, is preferably rice starch and is used in an amount of 0,1% to the complement to 100% of the two other used compounds.
Said adsorbent is obtainable by means of a process comprising the following steps:
the action of the packaging explicates itself through the possibility of the semipermeable film in combination with adsorbent to create micro atmosphere in contact with the plant which is different from that normally present in the atmosphere that permits to reduce to a minimum its metabolic requirements, without irreversible alterations.
the adsorbent is preferably placed under the vase and/or under the stem; in fact it is able to interact dynamically with the elements indispensable for the life of the vegetable material and, releasing 02, CO2 and water can create an equilibrium that brings to a minimum the vegetative activity of the plant.
the preferred positioning under the vase is not connected to the modality of action, that would result unchanged also in other positions, but depends on reasons connected to the operations of plant confectioning into the packaging and on reasons of image.
adsorbent is closely connected to that one of the semipermeable film used also for the confectioning, that specifically modulates the passage of atmospheric gases from the inside of the packaging towards the outside and vice versa.
the choice of the type of film and the weight of adsorbent that is inside the packaging depends on the typology of confectioned plant that is to say its respiratory rate and transpiration.
the semipermeable films used for the active packaging of the different typologies of plants show values of permeability indicated in following table 1.
Table 1 range of permeability to O2, CO2 and water vapour of plastic films used in the active packaging.
Properties Measure unit Tipical values Speed of transmission of the water vapour g/24 h*m 2 (38°C, 100%UR) 20-30 Permeability to O 2 Cm 3 /24h*m 2 *bar 8.000-12.000 Permeability to CO 2 Cm 3 /24h*m 2 *bar 35.000-45.000
the permeabilities to oxygen and carbon dioxide have been determined at constant pressure of gases with isostatic method employing the Lyssy instrument, Model GMP 200 in agreement to what reported by Guisheng et al., 1995. Before the measure the films have been conditioned to 0% of UR. The measure of the speed of transmission of the water vapour has been determined according to what reported by Maner et al., 2000.
Semipermeable films for usage in the active packaging according to the present invention include one or more compounds chosen from the class formed from Polyvinyl chloride, simple polyamide, Polystyrene, Polypropylene, Polyester, aliphatic polyesters, aromatic polyesters, ethylene/vinyl acetate copolymer, polylactates (lactic acid polymers) and polyethylene among which are particularly preferred high density polyethylene (HDPE), low density polyethylene (LDPE), polyester, and polypropylene (PP).
HDPE high density polyethylene
LDPE low density polyethylene
PP polypropylene
the active packaging according to the present invention is able to slow down the respiratory activity of the plant and its correlated metabolic phenomena allowing the normal restoration of the physiology after the packaging is opened.
the preliminary part of the tests has been devoted to verification of the effectiveness of the active packaging (semipermeable film + adsorbent) in comparison with relative controls formed by plants and cut flowers without confectioning and also by plants and cut flowers only with the semipermeable film.
the effectiveness of the active packaging has been following tested on the plants also without light, placing the confectioned samples with the active packaging for a period of 15 days without light and afterwards exposed to the natural cycle of light always inside the active packaging. Below are reported the different types of packaging used for the tests of plants and cut flowers
the qualitative state of the plants in the various modalities of conservation has been evaluated through the normal vegetative parameters according to typology of plant used for test as withering and modification of the colour of flowers and leaves, development of vegetative buds and fungi attacks recorded by digital images.
the qualitative-quantitative evaluation of the vegetative parameters of the plants submitted used for the conservation tests has been carried out by means of sensorial test using a panel constituted from 9 judges of expert of the floriculture sector.
the qualitative descriptions chosen for the sensorial valuation of the samples have been: aspect of the leaves, colour of the bracts, aspect and development of vegetative buds, fungi attacks for the plants and general turgidity, aspect of the leaves and opening of button for the cut flowers.
the evaluation set applied a score variable between 1 and 4, (1 insufficient, 2 sufficient, 3 good, 4 optimal) relative to the average of the scores obtained by means of the overall judgment of the qualitative descriptors.
the insertion of the adsorbent (photos 7-9) inside of the packaging (I6) can regulate all the metabolic phenomena annexed to the vegetative activity of the plant establishing the correct equilibrium between CO2, O2, and water vapour of the internal micro atmosphere of the packaging. In these conditions clear signs connected with water and respiratory stresses have not been found which in the samples (untreated plants and packed plants with semipermeable film) have damaged the structure and the initial quality of the vegetable material.
