Abstract
The invention discloses a refrigerating technological process for green soya bean fresh pods, relating to the field of refreshing and storing agricultural products. The refrigerating technological process comprises the steps of picking, cleaning, sterilizing and disinfecting green soya beans, sealing and bagging, disinfecting a storehouse, controlling the temperature, controlling the content of oxygen, controlling the content of carbon dioxide, controlling the humidity of the storehouse, and delivering the green soya beans from the storehouse. According to the green soya bean refrigerating technological process, suitable conditions beneficial to storing green soya beans are determined, reasonable temperature, humidity and gas components in the storehouse are ensured, the problems of water loss, ageing, yellowing and rotting in the green soya bean storage process are solved, the storage time of the green soya beans is prolonged, the color and the texture can not be damaged, the development in the vegetable industry is promoted, the additional value is increased, and the building of a demonstrative mode in a high-efficiency agriculture industry chain is promoted.
Description
Technical field
The present invention relates to a kind of agricultural products fresh-keeping and store field, be specifically related to the bright pod refrigeration of a kind of large green soya bean technological process.
Background technology
Large green soya bean is that late-maturing dish is used soybean, refers in the drum grain phase and cuts edible soybean to blue or green between first ripe breeding time phase, and China is called green soy bean (or blue or green green soy bean), and Japan is called a beans (or beer beans).Bright green soy bean is rich in the several kinds of mineral elements such as protein, vitamin A, B, C, E and calcium, phosphorus, iron, is a kind of high-nutrition food.Protein is the first nutrient that maintains human survival, and soybean protein is one maximum in the vegetable protein that the mankind can utilize in the world at present.In addition, green soy bean has gentle glutinous fragrant and sweet mouthfeel and special beany flavour, can be used for the pantries such as Household diet, restaurant, aviation, is a kind of nutritious, the Specialty vegetable be loved by the people.Fresh green soy bean water content is very high, and very easily dehydration is wilted or rotted, and is difficult to long-term storage, and in selling and transporting, loss is very large.And green soy bean while plucking temperature higher, tend to produce yellow, rot, the germination phenomenon, thereby reduced edible quality and nutritive value, produce the busy season and sell that the proportion of goods damageds are larger not in time.This phenomenon very easily produces market supply and demand contradiction, dampens vegetable grower's enthusiasm for production.The key addressed these problems is that green soy bean is carried out to fresh-keeping processing processing, green soy bean mainly exports with the form of cold storing and fresh-keeping or quick frozen product, or using and sell in country fair as fresh vegetables with the form of pod, value-added content of product is lower, color and local flavor very easily bad change in storage and processing due to green soy bean, it is also quite short to make the green soy bean benevolence can shelf-life, and volatile unhairing beans original color and luster and mouthfeel.Except freezing band pod green soy bean is arranged, also there is no long shelf life green soy bean product on market.In the winter of an expanse of white snow, people are eager to green yearning, if in can be in the winter time particularly Spring Festival to enjoying emerald green bright green soy bean, change dull uninteresting dietary structure in winter, surely can be subject to consumers in general's favor.Therefore, make the green soy bean product keep good color and luster and texture, extend the shelf life in the urgent need to.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of technological process simple, can extend the bright pod refrigeration of the large green soya bean technological process of large green soya bean shelf-life.
Technical problem to be solved by this invention realizes by the following technical solutions:
The bright pod refrigeration of a kind of large green soya bean technological process is characterized in that: comprise the following steps:
1) pluck ripe large green soya bean and carry out the useless bright pod green soy bean of sorting removal;
2) the bright pod green soy bean after sorting is carried out to timely precooling;
3) use 100mg/L stable chlorine dioxide disinfectant or 300-500ppm liquor natrii hypochloritis to carry out the sterilizing processing in the green soya bean after precooling in step 2;
4) by high-quality freshness protection package and sealing that to put into through leak test inspection and wall thickness after the bright pod green soy bean weighing after disinfection in step 3 be 0.025-0.05mm;
5) storehouse is adopted disinfectant fresh-keeping warehouse is carried out disinfection and seal 4 hours, and then open ventilative 1 hour;
6) the sealing freezer is adjusted to 1 ℃-2 ℃ by green soy bean precooling 24 hours by temperature of ice house;
7) by precooling in step 6 after 24 hours storehouse temperature drop to 0 ℃-1 ℃ continue precooling 48 hours;
8) oxygen content in freezer is adjusted to 2%-4%, carbon dioxide content is adjusted to 2%-10%;
9) every 4-5 days, freshness protection package is opened to bag stirs green soy bean gently and standing 4-6 hour envelope again;
10) humidity in storehouse is controlled to 85%-90%;
11) by precooling in step 7 the storehouse temperature drop after 48 hours to-1 ℃-0 ℃ refrigeration until outbound;
The standard that in described step 1, fresh soyabean is plucked is: the large green soya bean maturity of harvesting is that eight minutes ripe, beanpods surperficially have that the thin fine hair of one deck, color and luster are bud green, the harvesting of band handle, disease-free or mechanical wound, shell opening not.
The formalin solution that the disinfectant adopted in described step 5 is 35～40%.
The present invention has determined the suitable condition of the storage that is conducive to large green soya bean, rational temperature, humidity, gas componant in storehouse have been guaranteed, dehydration in large green soya bean storage, aging, yellow, rotten problem have been solved, improved the storage time of large green soya bean and can not destroy color and luster and texture, promoted the development of vegetables industry, improve added value, promote the construction of high-efficiency agriculture industrial chain pattern model.
