Abstract
The invention relates to a preparation method of a honey peach preservative, comprising the steps of taking chitosan, sodium benzoate, sodium polyacrylate and organic acid as main active components and putting the active components into water for stirring and standing reaction to prepare the honey peach preservative; the honey peach preservative of the invention is sprayed on the surface of honey peach to form a layer of colourless, transparent and edible film on the surface of honey peach; due to the unique physical and biological effects of chitosan, the honey peach preservative has the effects of sterilization, preservation and antisepsis, so that the preservation time of honey peach is greatly prolonged, honey peach can be stored for a long time 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 preparation method of honey peach antistaling agent.
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
Purpose of the present invention is overcoming the deficiencies in the prior art, and a kind of preparation method that can prolong the honey peach antistaling agent of honey peach fresh keeping time greatly is provided.
Purpose of the present invention realizes by following technical scheme: described honey peach antistaling agent is main live part with shitosan, Sodium Benzoate, Sodium Polyacrylate and organic acid, drops in the water to make through stirring, arrest reaction step, and the detailed process method is as follows:
(1) take by weighing 4～5 parts of shitosans, 0.5～0.6 part of Sodium Benzoate, 1～1.2 part of Sodium Polyacrylate, 2～2.2 parts of organic acids, they are joined in 91～92.5 parts of water, stirred 5～6 minutes, the temperature of control mixed solution is at 20～25 ℃;
(2) will go up the mixed solution arrest reaction that makes of step 10～15 minutes, promptly make the honey peach antistaling agent.
As a further improvement on the present invention, the shitosan about preferred 600,000 molecular weight of described shitosan.
As a further improvement on the present invention, one or more in the preferred amion acetic acid of described organic acid, ethylenediamine tetra-acetic acid, iminodiacetic acid or the diethylene-triamine pentaacetic acid.
As a further improvement on the present invention, the preferred conductance of described water is no more than the pure water of 50 μ s.
The present invention compared with prior art, utilize the chitosan solution of preparation to be sprayed on the honey peach surface, form one deck water white transparency and edible film on the honey peach surface, because the unique physical and the biological action of shitosan, can play sterilization, fresh-keeping, antiseptic effect, make the fresh keeping time of honey peach prolong greatly, energy longer-term storage and long-distance transport, can not break down at short notice, reduce the cost of storage in the transportation, and be beneficial to consumer's storage, ensured orchard worker and consumer's interests with cheap cost.
