Description

A kind of molecular film fruit and vegetable fresh-keeping agent with the edibility material preparation
One, affiliated field
The present invention relates to a kind of fruit and vegetable fresh-keeping agent, particularly a kind of all with the molecular film fruit and vegetable fresh-keeping agent of edibility material preparation.
Two, background technology
China's fruit cultivated area is big, and is wide in variety, output is high, and the various places that spread all over the country, fruit belt.About 5,000 ten thousand tons of national annual fruits output accounts for 14% of global total output, ranks first in the world.Because China's fruit freshness preserving is backward in technique, has every year a large amount of fruit to rot in storage and transport process, according to statistics, the loss that causes therefrom accounts for about 30% of national annual fruit total output.The shortage of fruit freshness preserving means has become " bottleneck " that the restriction orchard worker increased income and hindered China's fruit industry development.
The backwardness of fresh-keeping means has also influenced the outward appearance and the quality of fruit, and more and more higher to the requirement of fruit quality and outward appearance on the market, this makes the fruit industry of China face a severe challenge.For example, Kiwi berry is the wild fruit tree resource of a kind of high nutrition, high benefit, after cultivation, has formed industrialization production.China is the native place of high-quality Kiwi berry kind, in the known 66 kinds of Actinidias in the whole world, 62 kinds of former China of originating from is arranged, and homemade Kiwi berry occupies very great share on the market at home and abroad in the past always, and enjoys higher price.The Kiwi berry that New Zealand produces all is less than China far away on kind and output, but its product has had remarkable advantages in outward appearance with on storage period after modernized preservation technique is handled.In recent years, New Zealand produces Kiwi berry and has seized increasing share in the international market, even dumps Chinese market in a large number.At present, obvious day by day in the advantage of import Kiwi berry on Chinese market, and price exceeds 2 to 3 times of homemade kinds.This lesson to China is very deep.
This severe situation also is present on other fruit.At present, the price of domestic market upper inlet fancy fruit generally exceeds 2 to 5 times of homemade kinds, and the pressure of " foreign-water fruit " serious threat has contained more that to the survival and development of Chinese fruit industry China's fruit enters the international market.
Trace sth. to its source, why the fruit that developed country produces has so big competitiveness, and key is to rely on advanced fresh-keeping means to prolong the shelf-life, and has improved the quality and the outward appearance of fruit greatly.So, having only the quality that improves China's fruit and outward appearance, prolongation storage period, just can dominate the market.Behind China's accession to the WTO (WTO), solve the fruit freshness preserving problem and improve the key of China's fruit especially in competitiveness in the international market.
At present the fruit freshness preserving technology of China is compared with advanced international standard and is also had suitable gap, especially efficiently, at a low price, safe anti-corrosive fresh-keeping preparation extremely lacks.On the other hand, the fund in the society is also less relatively in the input in this field.Therefore, introducing international advanced technology, financing, each side cooperation by all kinds of means, produce the novel fruits fresh-keeping agent that is suitable for Chinese market, is one of basic outlet that solves China's fruit fresh-keeping problem.Under this background, quaternary Bioisystech Co., Ltd is the requirement of satisfying China's fruit industry development and domestic fruit freshness preserving market, has been introduced molecular film fruit antistaling agent technology by U.S.'s biotechnology research.
In the whole process of fruit accumulating and sale, resolving the fruit fresh-keeping problem all is a key.For a long time, other fruit production of the China and the world and consume big state and all dropped into great human and material resources and financial resources is so that fruit freshness preserving technology and means are more perfect.
The industrialization and the modernization level of China's fruit production at present and the industry that flows are also lower, and domestic fruit freshness preserving means commonly used still rely on following several traditional fruit freshness preserving means.
1. to store be to produce the means that the fruit district generally adopts to polybag, and its method is that fresh fruit is placed in the polybag with certain air permeability, suppresses fruit metabolism, to prolong the shelf life.Because of fruit can produce the ethylene gas with dematuration at lay up period, when this gas concentration is higher, still can cause fruit to take place to rot and go bad, this is the open defect of this kind method;
2. the natural low temperature storehouse is stored fruit is placed in cellar, cave dwelling or the self-built storehouse, is equipped with the measure of easy ventilation and controlled humidity, can prevent in to a certain degree that fruit from rotting or dehydration, but reserves is limited and the acute variation of can't resist temperature and humidity;
3. to store be the method that large-scale fruit accumulating or sale enterprise generally adopt for freezer or air-conditioned cold store, and its advantage is that hoarding effect is good and be not subject to seasonal restrictions.Investment is big, the power consumption height but freezer and air-conditioned cold store are built, and storage capacity is limited, and this has improved the cost of fruit freshness preserving greatly.With regard to 5,000 ten thousand tons fruits output in China's every year, refrigeration ability wretched insufficiency.
Polybag storage method and low temperature storehouse storage method be also intersection use sometimes, and they all are more original fresh-keeping means, mainly controls by operator's experience.Its fatal weakness is limited by season and weather, only is applicable to autumn and winter two low temperature seasons, in case temperature raises or adverse weather, fruit can rot rapidly.
Original local flavor of product and nutrition.Its shortcoming is that the effect of more loaded down with trivial details and anti-rotten, anti-dehydration of application process and the growth that suppresses bacterium is strong inadequately.
3) crude antistaling agent
Adopt granulated sugar, starch, crust amine, aliphatic acid, polyester thing or other by the translucent liquid material that the raw material modulation of extracting in the natural plants forms, cover fruit surface after the method film forming of available spraying, dipping, brushing.Because this antistaling agent can form the film of approximate sealing on the surface of fruit, enter fruit internal so can block most of oxygen, has suppressed the maturing process of fruit, and play the effect that prolongs storage and freshness date.Its shortcoming is that the cost of part material is higher.
