Abstract
The invention relates to a honey peach preservative and an application method thereof; the honey peach preservative comprises the following components according to corresponding parts by weight: 4-5 parts of chitosan of 600, 000 molecular weight, 0.5-0.6 part of sodium benzoate, 1-1.2 parts of sodium polyacrylate, 2-2.2 parts of organic acid and remainder of water; the application method of the honey peach preservative comprises the steps of batching, spraying and drying. By coating preservative on the surface of honey peach, the invention reasonably utilizes filming property, inoxidizability, bacteriostasis and sterilization effects and synergy effect of natural state biological molecules, so that the freshness time of honey peach can be greatly prolonged, honey peach can be stored for along term and transported for a long distance without going bad in a short time, and the storage cost in the transporting process is reduced, thus being favourable for storage by customers and ensuring the benefits of fruit growers and consumers with low cost.
Description
Technical field
The invention belongs to the food preservative technology field, particularly relate to a kind of honey peach antistaling agent and application process thereof.
Background technology
Honey peach is the special product of Wuxi, and honey peach is nutritious, and the meat sweet juice is many, contains and enriches irony, can increase human body hemoglobin quantity, is the fruit that broad masses of the people enjoy a lot.
Honey peach is because to contain sugar part many 10%～15%, washiness about 85%, and the surface dense hair that gathers, dense nominal diameter is 0.2～0.15mm, 80～100/cm of surface area dense hair coverage density
2, dense hair height 2～4mm is because dense hair coverage rate height, anti-corrosion material is not easy directly and the epidermis combination, so do not reach preservation, if big yield soaks fresh-keeping liquid, increase fresh-keeping cost again, agricultural byproducts itself are worth not high, and increasing cost directly influences consumer's interests and orchard worker's interests.Form soft fluorine disease and the brown rot (growth and procreation by brown rot germ cause) of the rotten principal element of honey peach by peach.Add that honey peach just is in maximum temperature season (30～35 ℃) in a year harvest time, so fresh-keeping this technology of honey peach perplexs the orchard worker always, without fresh-keeping, can not longer-term storage, can not transport for long-distance, can not mutual extrusion, directly influence orchard worker's income, wastage is also big.
Summary of the invention
The objective of the invention is at weak point of the prior art, provide a kind of technology simple, cost is low, the honey peach antistaling agent and the application process thereof that can prolong storage period greatly.

Principle of the present invention and advantage are:
Antistaling agent can form the very thin pellicle of one deck on the surface of honey peach, hinders the transpiration of honey peach, thereby reduces the loss of moisture and the weightlessness of honey peach;
Antistaling agent has the characteristics of permselectivity, can hinder O
2Enter in the film, and restriction CO
2Outside the discharge film, allow honey peach ethene between the storage life in film, to overflow simultaneously, make the CO that keeps higher concentration in the film
2, suppress its respiration, keep honey peach chromatic colour and hardness preferably;
This antistaling agent can stop the decline of some honey peach sugar and acid content between the storage life;
This antistaling agent can reduce thick during the fat oxygen of fruit and the vigor of enzyme, thereby suppress the generation of MDA, improved cell membrane stability, prevent the adipose membrane peroxidating of cell and the seepage of content;
This antistaling agent can significantly improve the vigor of superoxide dismutase in the honey peach, reduces the damage of radical pair cell membrane, thereby delays the aging of cell, has promptly prolonged the storage life;
Because chitosan film has limited the respiration of honey peach, reduced " sweating " phenomenon of honey peach between the storage life in this antistaling agent, reduced the globule on honey peach surface, made pathogen be difficult for infecting honey peach;
Shitosan can induce honey peach to produce the series of defence reaction mechanism in this antistaling agent, as stopping up hole skin, produces protective plant protecting agent, and the thickening of fruit cell wall hinders the pathogen invasion and attack.
