Description

A kind of preserving fruit and vegetable utilizing plastics film and manufacture method thereof
Technical field:
The present invention relates to a kind of preserving fruit and vegetable utilizing plastics film and preparation method thereof, particularly a kind of preserving fruit and vegetable utilizing plastics film that contains inorganic functional material and preparation method thereof.
Background technology:
Fruit, vegetables are indispensable human foods.Along with agrotechnical development, the improvement of fruit and vegetable varieties, innovation and popularization are very rapid, the value of fruits and vegetables is more and more higher, the postharvest fruit and vegetable preservation technique can overcome the restriction of conditions such as time, space, weather, fruits and vegetables are circulated, and the effect of fruits and vegetables being guaranteed the quality, improving its commodity value is extremely important.
The postharvest fruit and vegetable preservation technique has low-temperature cold store, controlled atmosphere, preservation agent processing, plastics bag or paper bag packing etc., and freezer storage and controlled atmosphere cold facility investment are big, the cost height; Handle gourd, fruit and vegetable with preservation agent, there is safety issue in residual preservation agent; Packing fruits and vegetables with Plastic film Bag, is a kind of simple and easy to do fresh-retaining preserving means.
The plastic film packaging bag that present preserving fruit and vegetable utilizing is used is made with polyethylene, polypropylene, polyvinyl chloride, polyester etc., and fresh keeping time is short.In order to improve the Plastic film Bag fresh-keeping effect, people attempt to improve by following measure, but still can't satisfy fruits and vegetables and change service requirementss such as storage in season, long-distance transport, outlet: (1) makes plastics bag have the performance that absorbs gas:
The inorganic porous material that in polyethylene film, adds 3%-5%, as large space between muscles stone, coral powder etc., can absorb the ethylene gas that produces in the bag, but add porous mass and can not absorb a large amount of ethylene gas that fruits and vegetables send fully, [Chinese plastics only can prolong storage period in the not long time, 2000 (10), 15].Japanese Patent JP58-220648 and JP56-18901 play the effect of decomposing ethylene gas respectively with aluminosilicate and vermiculite, zeolite-loaded potassium permanganate and be compounded in the plastics film.(2) ventilation property of increase plastics bag
Natural radioactivity potter's clay and polyethylene are mixed and made into the plastics film that has superfine micropore, and gas and water-dispersion that fruits and vegetables are produced in storing and transporting send out [Chinese plastics, 2000 (10), 15].Or on film, offer aperture or the micropore of some 20-100 μ m, increase the ventilation property of film and regulate a bag composition of gases within (controlled atmosphere) [packing technique (day), 2000,35 (5), 27].And the window (silicon controlled atmosphere window, China Patent No. 95204859) that on common plastics storage bag, has silicon rubber film.Korean Patent KR2001-39142 obtains good steam breathability by add 500-800 order diatomite in plastic film.But such production quality control difficulty, the fresh-keeping effect instability.(3) give freshness protection package and have germ resistance
The mould inhibitor Top Form Wormer is added in polyethylene film, polypropylene film, polyvinyl chloride film and the various composite membrane with the amount of 0.1%-0.2%, make mildew-resistant plastics film (industrial bactericide, p.257, Chemical Industry Press, calendar year 2001).Sabinol is mixed in the polyethylene multilayer bag, it is slowly distributed, have antibiotic, anti-mildew, inhibition is accelerated the ripening and the function [packing technique (day), 2000,35 (5), 14] of breathing.Japanese Patent JP2001-163999, JP4-112741 and JP3-111264 adopt the method fruit and vegetable preservation that adds antiseptic-germicide in film.But use this class antimicrobial technology separately, only can delay fruits and vegetables to a certain extent and rot.
