Embodiment 1

[0025] When the surface of the fresh fruit is completely bright red, it is hand-picked with a stalk. Choose a fruit with large grains (thousand-grain weight is more than 1200g, the same below), bright color, with a stalk, and no pests and diseases. Use tap water to remove the silt and other sundries on the fruit surface, soak in 0.5mg / L ozone solution for 40 seconds, drain, wash once with pure water and drain; use a strong wind blower to dry the surface water Blow dry; put the dried goji berries into a fresh-keeping tray with a height of 5cm and a thickness of 3cm; stack 5 trays of fresh goji berry into a polyethylene fresh-keeping bag, open the mouth of the fresh-keeping bag and put in- 1°C cold air pre-cooling room for pre-cooling. After the core temperature reaches 0°C, the pre-cooling ends; high-efficiency ethylene remover (1 pack per 5 kg of fresh fruit, 10 g per pack) and SO 2 Slow-release preservative (one pack per 5kg of fresh fruit, using the special preservative for ...

Embodiment 2

[0027] When the surface of the fresh fruit is completely bright red, it is hand-picked with a stalk. Choose a fruit with large grains, bright color, a stalk, and no pests and diseases. When picking it, handle it gently and set it aside for use; use tap water to clean the surface of the fruit. Wait for the sundries to be removed, soak in 0.7mg / L ozone solution for 35 seconds, drain, wash once with pure water and drain; dry the drained wolfberry fresh fruit with a strong wind dryer to dry the surface water; dry the dried wolfberry Put the fresh fruit into a fresh-keeping tray with a height of 5cm and a thickness of 3.5cm; stack 5 trays of fresh goji berries into a polyethylene fresh-keeping bag, open the mouth of the fresh-keeping bag and put it in a cold air pre-cooler at -1°C for pre-cooling. After the fruit core temperature reaches -1°C, the pre-cooling ends; high-efficiency ethylene remover (one pack per 7kg of fresh fruit) and SO 2 The slow-release preservative (one pack pe...

Abstract

The invention relates to a preservation method for fresh lycium barbarum. The preservation method for the fresh lycium barbarum includes the following steps of (1) taking the fresh lycium barbarum, washing the fresh lycium barbarum, removing impurities on the surface of the fresh lycium barbarum, soaking the fresh lycium barbarum in ozone solution with concentration of 0.5-1.0 mg / L for 30-40s, draining the fresh lycium barbarum, washing the fresh lycium barbarum with purified water, draining the fresh lycium barbarum, blow-drying the surface of the fresh lycium barbarum, putting the fresh lycium barbarum in a preservation plate for later use, (2) putting every 5-8kg of the fresh lycium barbarum processed through the step (1) into a freshness protecting package, putting the packaged fresh lycium barbarum with the opening of the package opened into a refrigeration house, precooling the fresh lycium barbarum, putting a pack of first preservatives and a pack of second preservatives into the freshness protecting package after the temperature of the core of the fresh lycium barbarum reaches 0-1 DEG C, tightening the opening of the package, putting the packaged fresh lycium barbarum into the refrigeration house with the temperature ranged from minus 2 DEG C to minus 1 DEG C, and refrigerating fresh lycium barbarum. The preservation method for the fresh lycium barbarum is low in process cost, simple and convenient to operate and practical in technology, and prolongs the preservation period of the fresh lycium barbarum.
