Abstract
The invention discloses a controlled freezing point refrigeration and preservation method of red Fuji apples, and relates to a fruit and vegetable refrigeration and preservation technology, aiming at solving the problems that after the existing storing method is used, the hardness of the pulp of fruits is rapidly reduced, and the fruits are low in sweetness and poor in quality. The controlled freezing point refrigeration and preservation method of the red Fuji apples comprises the steps of packaging the red Fuji apples by microporous freshness protection packages, precooling at the set temperature, sending the precooled apples into a fresh-keeping storehouse with the temperature of -1 to -3 DEG C, and maintaining the content of O2 to be 1-6% and the content of CO2 to be 0-5% in the fresh-keeping storehouse. The controlled freezing point refrigeration and preservation method is high in practicality and operability, and can be used for remarkably improving the storage effect of the red Fuji apples and improving the quality of the red Fuji apples, so that the sound development of the whole industry can be promoted.
Description
Technical field
The present invention relates to fruits and vegetables freezing technology, be specifically related to a kind of red fuji apple ice temperature cold-storage and fresh-keeping method.
Background technology
In recent years, along with red fuji apple production link single fruit bagging technique widely uses, the storage property of fruit is declined, but preservation technique still adopt the seventies and eighties earth kiln hole, ventilation storehouse, cool the simple and easy preservatives such as storehouse, and the nineties 0 DEG C of cold storage of constant temperature and air control storage.Use traditional preservative, duration of storage fruit fresh hardness declines fast, and sugariness is low, poor quality, have impact on the sound development of red fuji apple industry to a certain extent.
Ice-temperature technique is the third generation preservation technique after refrigeration and air conditioned storage.Ice temperature (controlled freezing point) refers to the herring bone region from 0 DEG C to organism solidification point.Be still the organism of a work after fruit and vegetable picking, its respiratory metabolism physiological activity does not stop, and the respiration of fruits and vegetables can reduce by ice temperature fresh-keeping, even if it also can be suppressed to breathe in the later stage that fruit is fully ripe, fresh-keeping effect is obviously better than refrigeration and controlled atmosphere.The fruits and vegetables fresh-keeping through Icetemperature Storage still have longer shelf life after outbound, meet the standard of food hygiene and the requirement of environmental protection completely, are a kind of nuisanceless preservation methods.
Therefore, explore the ice temperature fresh-keeping technology of red fuji apple, with permanently effective fresh-keeping after ensureing Fruit, solve Problems existing in its storage, transportation, become a focus of research at present.
Summary of the invention
The present invention is that the fruit fresh hardness existed to solve existing preservative declines fast, and sugariness is low, inferior problem, and provides a kind of red fuji apple ice temperature cold-storage and fresh-keeping method.
The present invention is achieved by the following technical solutions:
A kind of red fuji apple ice temperature cold-storage and fresh-keeping method is packed by red fuji apple micropore freshness protection package, and precooling under DEG C condition, by the apple after precooling, sending into temperature is in the fresh-keeping warehouse of-1 to-3 DEG C, keeps O in fresh-keeping warehouse
2content is to 1-6%, CO
2content 0-5%.
Further, described fresh-keeping warehouse temperature is-1.5 to-2.5 DEG C, O
2content is to 2-4%, CO
2content 2-4%.
This research is compared under the suitableeest reserve temperature condition of ice temperature area, different controlled atmosphere composition O
2and CO
2on the impact of red fuji apple endogenous ethylene, respiratory intensity, physiological damage and storage effect, determine the scope of red fuji apple the suitableeest controlled atmosphere parameter and permission variation under ice temperature condition, and screening is to O
2and CO
2have high osmosis, can ensure again the micropore freshness protection package having higher relative humidity in bag, under solving ice temperature condition, air-conditioned cold store humidification system freezes and cannot keep this technical barrier of ambient humidity.
Utilize the inventive method that red fuji apple is preserved 8 months, percentage of water loss is less than 2%, and rotting rate is less than 2%, and flesh firmness is greater than 6kg/ cm
2, soluble solid declines and is less than 10%, and outward appearance is as before fresh, and quality keeps better.
Compared with prior art, the practicality of the inventive method and strong operability, can significantly improve the storage effect of red fuji apple, improves red fuji apple quality, promotes the sound development of whole industry.
