Embodiment 1

[0027] (1) Picking: Choose to pick fresh goji berries with a maturity of 85%-90%. Pay attention to retain the fruit stems and prevent mechanical damage. At the same time, choose to remove raw, moldy and rotten fruits and residual fruits. The principle of putting more baskets and less is used to prevent the fruits from being squeezed due to excessive blooming.

[0028] (2) Cleaning: Pour fresh wolfberry into a cleaning tank filled with 55°C hot water, and inject ozone from the lower end of the tank to form a slight "boiling" state, driving the fruit to roll continuously, improving cleaning efficiency, and cleaning for 7 minutes.

[0029] (3) Sterilization: Wash and drain for 5 minutes, then immerse fresh wolfberry in 12% garlic extract aqueous solution for 8 minutes to sterilize fresh wolfberry.

[0030] (4) Coating: Drain for 8 minutes after sterilization, and then immerse fresh wolfberry in a mixed solution of 0.2% chitosan, 0.1% glucose oxidase and 0.12% glucose for 4 minute...

Abstract

The invention discloses a pollution-free fresh-keeping method of fresh wolfberry fruits. The technology comprises the following steps: (1) washing; (2) sterilizing; (3) film coating; (4) drying by blowing; (5) sub-packaging; (6) air conditioning and the like. In the fresh-keeping method, a film coating manner is used for keeping fresh, and a packaging bag made of a polyethylene-molecular sieve composite film is matched, so that the respiration effect of the fresh wolfberry fruits is minimized; the fresh-keeping technology provided by the invention does not use any toxic or harmful substance; afilm-coated fresh-keeping agent contains no toxic or harmful substance; meanwhile, the fresh-keeping method provided by the invention does not generate any toxic or harmful substance and the fresh-keeping period of the fresh wolfberry fruits is greatly prolonged; meanwhile, the fresh-keeping method can be implemented and finished on the basis of existing fresh-keeping implementation equipment without adding more new equipment, and therefore the method has cost advantages.

Description

technical field [0001] The invention relates to a fresh-keeping technology for agricultural products, in particular to a fresh-keeping method for fresh wolfberry. Background technique [0002] The value of Lycium barbarum medicinal and edible homology has been recognized by more and more consumers. It has an important position in traditional medicine and its medicinal value is highly respected. "Compendium of Materia Medica" records: Lycium barbarum can nourish the kidney and generate essence, nourish the liver, Improves eyesight, strengthens bones, relieves fatigue, improves color, improves eyesight and calms nerves, and makes people live longer. At present, in the consumer market, most goji berries are processed into dried goji berries from fresh goji berries and eaten by consumers. Compared with fresh goji berries, dried goji berries not only cause a certain degree of loss of nutrients during the drying process, but also have a better taste and The experience is also rel...
