Abstract
The invention discloses a longan fresh-keeping method. The method comprises the steps: picking longan with 80 percent of the maturity degree, carrying out simple screening to remove rotten, cracked and damaged fruits and fruits with plant diseases and insect pests, then cleaning surface impurities, and allowing the cleaned longan to go into a conveyor belt for further sorting; sending the sorted longan into an ultrasonic cleaning water tank for further cleaning, and then adding into an ozone aqueous solution having sterilizing and pesticide-degrading efficacies for rinsing, sterilizing and deinsectization of the fruits; after ultrasonic cleaning, allowing the fruits along with the conveyor belt to go into a cold treatment room for cold treatment, and then allowing to go into an isolating room for gas treatment; and after completing gas treatment, allowing the fruits to go into a fresh-keeping treatment procedure, then packaging, and sending into a refrigeration room for low-temperature storage. The method can effectively allow the guarantee period of the fresh fruits to reach more than 50 days and the on-shelf life to reach more than 5-7 days.
Description
Technical field:
The preservation method of the present invention and fruit, the particularly preservation method of a kind of longan, longan.
Background technology:
At present, the preservation method of longan, longan is mainly by medical bactericide soaking and washing the method packing, refrigerate with antistaling agent, but goes out added rear at most also can only the depositing approximately one day of freezer; Gas kill bacteria and the insect that another kind method utilization burning sulphur produces also cut off the sulfenyl of the part organized enzyme in fresh fruit, but process easily pollutes, and makes again pericarp variable color, pulp spoiled, and after stove drying shelf life be also difficult to super two days later.Longan, longan quality are existed to larger destruction, are not desirable methods.
Summary of the invention:
The object of the invention is the drawback existing for conventional art, and the preservation method of a kind of longan, longan is provided, use the present invention effectively the fresh fruit shelf-life to be reached more than 50 days, the added shelf-life reaches more than 5-7 days.
For realizing above-mentioned technical purpose, the technical scheme that the present invention takes is: the preservation method of a kind of longan, longan, comprise and pluck longan, the longan that maturity is 8 one-tenth, through simply screening, remove rotten, split, undermined ill insect pest fruit, then clean surface impurity, the longan after cleaning, longan enter conveyer belt and do further go-no-go; Lichee after go-no-go is sent into Ultrasonic Cleaning tank and is further cleaned, then put into there is sterilization, the ozone water solution of degrading pesticide effect makes rinsing and sterilization and disinfestation to fruit; After Ultrasonic Cleaning, with conveyer belt, enter and between cold treatment, carry out cold treatment, then enter and between isolation, carry out gas treatment; After completing gas treatment, enter Preservation Treatment operation, then pack and enter freezer and make cryopreservation.
The specific embodiment:
Below in conjunction with embodiment, the present invention is further described:
First, guarantee to select high-quality without fruit, the minimizing fruit moth rate of disease and pest, accomplish fluently the basis of preservation and freshness.Owing to utilizing Ultrasonic Cleaning tank to clean, be cleaned longan, longan in relatively static, the cleaning function that ultrasonic cavitation phenomenon is brought is able to effective performance, cleaning efficiency is high, fruit and vegetable surface cleanliness is high, fruit and vegetable not damaged through sterilizing repeatedly repeatedly, has significantly extended the preserving fruit and vegetable utilizing phase.Adopt the cold treatment of indoor ozone sterilization to carry out the cold treatment of darker degree, then enter between isolation and carry out gas treatment, then enter Preservation Treatment operation, pack and enter freezer and make cryopreservation, complete whole preservation process.
Claims (1)
1. the preservation method of a longan, longan, comprise and pluck longan, the longan that maturity is 8 one-tenth, through simply screening, remove rotten, split, undermined ill insect pest fruit, then clean surface impurity, the longan after cleaning, longan enter conveyer belt and do further go-no-go; Lichee after go-no-go is sent into Ultrasonic Cleaning tank and is further cleaned, then put into there is sterilization, the ozone water solution of degrading pesticide effect makes rinsing and sterilization and disinfestation to fruit; After Ultrasonic Cleaning, with conveyer belt, enter and between cold treatment, carry out cold treatment, then enter and between isolation, carry out gas treatment; After completing gas treatment, enter Preservation Treatment operation, then pack and enter freezer and make cryopreservation.
