Abstract
The invention discloses a degradable cereal prolamin-chitosan composite packaging film for fruits and vegetables and relates to the technical field of packaging films for the fruits and the vegetables. The packaging film is prepared from raw materials in parts by mass as follows: 90-100 parts of cereal prolamin, 60-70 parts of carboxymethyl chitosan, 20-25 parts of cloves, 20-25 parts of propolis, 18-20 parts of sodium alginate, 15-20 parts of polyvinyl alcohol, 16-18 parts of nano calcium carbonate, 15-18 parts of epoxidized soybean oil, 12-15 parts of fumed silica, 10-12 parts of zinc sulfide, 10-12 parts of konjac glucomannan, 8-10 parts of low-methoxyl pectin, 8-10 parts of curdlan, 6-9 parts of soy isoflavone, 5-8 parts of genipin, 3-6 parts of polyglycerol fatty acid ester and 800-1000 parts of water. The cereal prolamin and the chitosan are used as main raw materials, and various aids are used as auxiliary materials, so that the produced packaging film has higher physical and mechanical properties, selective permeability and antibacterial and anti-oxidation effects; besides, the selected raw materials can be degraded easily, so that the ecological environment is protected.
Description
Technical field:
The present invention relates to vegetable and fruit packaging technical field of membrane, be specifically related to a kind of degradable cereal gliadin-chitosan plyability vegetable and fruit packaging film.
Background technology:
Plastic film packaging is wrapping material most widely used on current fresh fruit and Vegetable produce.It has the transparency, can be clear that the situation of packaging product; It has moisture retention, can reduce the moisture loss of product, increases freshness; It has ventilation property, can play spontaneous controlled atmosphere effect, and extend fresh keeping time, it has stopping property, and product can be protected not contaminated.
At present, it is matrix that domestic used vegetable and fruit packaging film is generally the polymkeric substance such as polyethylene, polypropylene, polyvinyl chloride, by adding the mixing films made such as some softening agent, mineral filler, antiseptic-germicide.On the one hand, these packing films also exist the shortcoming of difficult degradation or degraded required time length, easily cause white pollution, affect environment; On the other hand, the ventilation property of these packing films is bad, if the oxygen concentration in packing film is too low or gas concentration lwevel is too high, fruit will produce anaerobic respiration, cause the volatile matter such as ethanol, acetaldehyde to accumulate, produce peculiar smell and differently to smell, reduce the flavor quality of fruit.
Summary of the invention:
Technical problem to be solved by this invention is to provide that a kind of preparation method is simple, the degradable cereal gliadin-chitosan plyability vegetable and fruit packaging film of good refreshing effect.
Technical problem to be solved by this invention adopts following technical scheme to realize:
