Abstract
The invention relates to a cold storage method of selenium-rich strawberries, and belongs to the technical field of preservation and storage of vegetables and fruits. The method comprises the following steps: selecting selenium-rich strawberries, pre-cooling and sterilizing, disinfecting and packaging, warehousing, and regulating humidity, temperature, and gas concentration. The invention has the following beneficial effects that proper conditions which facilitate storage of selenium-rich strawberries are determined, proper temperature, humidity and gas components in warehouses are guaranteed, the storage time of selenium-rich strawberries is prolonged, the quality of selenium-rich strawberries is not destroyed, the development of the industry of selenium-rich strawberries is promoted, and the additional value is increased.
Description
Technical field
The present invention relates to vegetables and fruits fresh-keeping and storing technology field, be specifically related to a kind of cold storage method of selenium rich strawberry.
Background technology
Strawberry is a kind of flowers and fruits of redness, and strawberry nutrition is worth high, and containing abundant vitamin C, effect of helpful digestion, meanwhile, strawberry can also consolidate gums, fresh breath, moist throat.Spring, the irascibility of people was often more vigorous, had some strawberry and can play inhibitory action.In addition, strawberry preferably eats after the meal, because it contains a large amount of pectin and cellulose, gastrointestinal peristalsis can be promoted, help digest, improve constipation, prevention hemorrhoid, intestinal cancer, selenium rich strawberry is a kind of new type of health strawberry that strawberry is extended in planting, not only have the original mouthfeel of strawberry, and be rich in trace element, useful health, all can planting in different regions throughout the year of selenium rich strawberry, but within 1 year, one batch can only be planted in a certain fixing region, therefore in the season of non-Strawberry ripening, have strawberry and must carry out outsourcing import, such cost not only improves, and mouthfeel also has certain difference.
summary of the invention
It is simple that technical problem to be solved by this invention is to provide a kind of technological process, can ensure that strawberry is fresh, the cold storage method of the selenium rich strawberry that mouthfeel remains unchanged.
Technical problem to be solved by this invention realizes by the following technical solutions:
A cold storage method for selenium rich strawberry, is characterized in that: comprise the following steps:
1., when selenium rich strawberry is ripe, collects or purchase qualified strawberry and carry out sorting, reject damaged, rot and the fruit of the unrooted base of a fruit;
2., by the selenium rich strawberry after sorting carry out preliminary precooling in time, forecooling method is that strawberry all to be put into temperature be that the freezer of 0 DEG C stores 1-2h.
3., by the selenium rich strawberry after preliminary precooling, take out, carry out air-dry;
4., 100mg/L stable chlorine dioxide disinfectant or 300-500ppm liquor natrii hypochloritis is used to carry out the process of sterilization spray disinfectant the selenium rich strawberry after air-dry in step 3;
5., by the selenium rich strawberry after disinfection pack, every bag is good with 80-100, and sealing vacuumizes in batches;
6., the selenium rich strawberry after pack in step 5 is sprayed benzoic acid Preservation Treatment after, putting into wall thickness is that the high-quality moisture-inhibiting bag of 0.02-0.05mm seals;
7., adopt disinfectant carry out disinfection to fresh-keeping warehouse and close 4 hours, and then open ventilative 1 hour;
8., be placed in sterile-processed freezer by the selenium rich strawberry of sealing in step 7, ventilation stretcher put in advance by freezer, and selenium rich strawberry is placed directly on ventilation stretcher;
9., close freezer oxygen content in freezer is adjusted to 2%-4%, carbon dioxide content is adjusted to 2%-10%, humid control at 85%-90%, and temperature is adjusted to 1 DEG C-2 DEG C, by selenium rich strawberry precooling 2 hours again;
10., by precooling after 2 hours storehouse temperature drop to 0 DEG C-1 DEG C continue precooling 3 hours;
constant refrigeration 10 hours after the Ku Wen of precooling after 3 hours is down to-0.5 DEG C-1 DEG C again;
freshness protection package to be opened bag and selenium rich strawberry is stirred gently and the envelope that leaves standstill 10 minutes again by During Cold Storage every 1-2 hour;
being loaded in incubator by the selenium rich strawberry of refrigeration after 10 hours adopts adhesive tape sternly to seal, and then control at 0-1 DEG C by storehouse temperature, constant temperature stores, and sells until take out the coming year or eats.
The described step 8. middle disinfectant adopted is the formalin solution of 20-35%.
The invention has the beneficial effects as follows: the present invention determines the suitable condition of the storage being conducive to selenium rich strawberry, ensure that rational temperature, humidity, gas componant in storehouse, improve the storage time of selenium rich strawberry and can not quality be destroyed, having promoted the development of selenium rich strawberry industry, improving added value.
