Description

A kind of fruits and vegetables composite fresh-keeping nutritional agents and preparation method thereof
Technical field
The present invention relates to a kind of fruits and vegetables composite fresh-keeping nutritional agents and preparation method thereof, belong to preserving fruit and vegetable utilizing field.
Background technique
Fresh fruit vegetables have carbohydrate abundant, and protein, vitamin, the various nutriments such as dietary fiber, are people The indispensable important component of class nutrition.In particular with China's improvement of living standard, the quality of fruit and vegetable is mentioned Higher requirement is gone out.
Fresh fruit and vegetable is after picking, and under the influence of respiration and transpiration, nutrient is gradually used up Be lost, appearance taste flavor is deteriorated, simultaneously as the sugar and moisture content in fresh fruit of vegetables are excessively high, storage transport with And during selling, bacterium easy to breed causes to rot.According to incompletely statistics, every year there are about 30% fruit and vegetable, It is picking, is transporting, rotting in storage and retail sales process or commodity property is lost, cause the huge wasting of resources And economic loss, how to extend the period of storage of fruits and vegetables, keeps the original flavor of fruits and vegetables, be fruits and vegetables production unit, storage stream Logical unit, wholesale and retail unit and the common focus of attention problem of terminal consumer.
Preservation technology currently on the market is broadly divided into following a few classes: cryopreservation is fresh-keeping, controlled atmosphere, and irradiation storage is protected Fresh, electrostatic is fresh-keeping, and ozone and anion are fresh-keeping etc..Above-mentioned preservation method, from the storage after fruit and vegetable picking, transport is sold Environment is started with, and the storage and transportation environment of optimization fruit is changed, and by the disinfection to environment, deoxygenation, the processes such as sterilizing realize fruits and vegetables storage The extension of phase.While using above-mentioned physical measure, it is aided with the application of fruit and vegetable fresh-keeping agent, further increases fresh-keeping effect.Together When, the extension that fruit and vegetable fresh-keeping agent also becomes the room temperature open environment such as shelf life of supermarket, market mainly selects.
Common fruit and vegetable fresh-keeping agent is broadly divided into chemical synthesis antistaling agent and natural component antistaling agent.Chemical preservation is fresh-keeping Such as adjacent sodium phenate of agent, biphenyl etc. can prevent microorganism from entering fruit from pericarp damage location, but it is to coming into fruits and vegetables The microorganism of epidermis does not work.Multiple spectrum internal-suction type fungicide such as benzimidazole has been widely used for the guarantor of fruits and vegetables It is fresh.But due to its drug resistance, the problems such as medicament residue, is extremely restricted its application, especially currently, food-safe The attention degrees such as pesticide residue are higher and higher, and such preservation and antisepsis fungicide is gradually backed out use.In addition there is fumigation type fungicide, Such antistaling agent volatilizees at normal temperature, using more for sulfur dioxide releasing agent, but, mistake more demanding to its operation concentration High sulfur dioxide residue will have a direct impact on the quality of fruits and vegetables.
Biological preservative is a kind of mode of fungus treatment, and external very active to this research, the country is still at the initial stage. Since this mode does not have the problems such as environmental pollution brought by chemical preservation antistaling agent, pesticide residue and drug resistance, and there is storage The advantages that condition is easy to control, processing target is clear.It is relatively successfully used to the fruits and vegetables such as pineapple, strawberry, spinach, Chinese cabbage at present.Such as Israel isolates two Yeasts from citrus surface, applies and shows on citrusfruit: energy antagonism penicillium promotes wound Healing.The U.S. has obtained satisfied commercial effect using isolated hay bacillus on the fruits such as apple, citrus.At present to bacterium The research of the antibacterial substance-bacteriocin generated is also more deep, the subtilin that such as extracts from Bacillus subtillis, from putting Extracted in line bacterium receive his rhzomorph, the poly- lysin that is extracted from the tylosin extracted in streptomycete, from streptomyces albus and from The antibacterial substance etc. found at least 222 kinds of edible mushrooms.It is especially pronounced to the research effect of lactic acid bacteria among these, it therefrom mentions Tens kinds of bacteriocins are taken.It is universally acknowledged and be cream in the biological preservative that more than 50 a countries and regions carry out industrialized productions Sour lactococcin.The microbiological antiseptic that China's approval uses is Lactococcus lactis rhzomorph and Na Ta rhzomorph.
The chemical preservative of biological source is increasingly becoming research emphasis, and a kind of high-efficiency multi-function fruits and vegetables that the U.S. develops are protected Fresh dose, safe and non-toxic at being grouped as by four kinds: sodium pyrophosphate, citric acid, ascorbic acid and calcium chloride can delay fruits and vegetables to aoxidize And enzymatic browning, it is preferable to the semi-finished product fruit and vegetable materials fresh-keeping effect after peeling (core), its color and tissue can be kept in 5d Structure.Britain develop a kind of arthropod shell extraction object-chitosan based on antistaling agent, for it is colourless, tasteless, nontoxic, Edible antistaling agent for fruit-vegetable pollution-free, without side-effects, can inhibit fruits and vegetables respiration and moisture evaporation, strawberry, cherry, apricot, Apple, tangerine, achieves comparatively ideal effect on grape at bergamot pear.
In various antistaling agents, the considerations of for people to factors such as environment, health, the application of chemical bactericide It is increasingly under suspicion, substitute technology (such as envelope, salt treatment) becomes the hot spot of research in recent years, but these technologies are so far not yet Obtain satisfied commercial effect.From at this stage, the integrated application of substitute technology combination low dosage chemical bactericide is undoubtedly one The reasonable selection of kind, the exploitation of safe and non-toxic natural antisepsis fresh-keeping agent, biological antiseptic preservative will be a broad aspect.Furthermore by In importance of the ethylene in fruits and vegetables ripening and senscence, new resistance to storage kind is cultivated with biotechnology or develops high effect nontoxic, nothing The ethylene receptor function inhibitor such as methyl cyclopropene (1-MCP) of pollution will be effective selection from now on.
In terms of the analysis to current preserving fruit and vegetable utilizing process and articles, current postharvest technology of fruits and vegetables, mainly from picking fruit Start with later, by means such as physics, chemistry, biologies, the storage condition of fruits and vegetables is changed, the fruit after picking is carried out Degerming is sterilized, film prevents moisture from evaporating, and slows down respiration, postpones afterripening, to achieve the effect that extend storage period.
