Embodiment 1

[0016] Example 1 Under the condition of no dew on a sunny day, 7 mature wolfberries with stalks were selected. After harvesting, 2 kg of wolfberries were put into food-grade plastic trays, and placed in a refrigerator at -1°C within 2 hours to soak the fruits with 30% alcohol. 5 minutes, and then intercooled with cold air at 1°C for 18 hours, so that the temperature of wolfberry reached 0.5°C, then put it into PE cling film with a thickness of 16 μm and a length of 100 cm×width of 80 cm produced by the National Agricultural Products Preservation Engineering Technology Research Center (Tianjin) 1 kg of each film, and then put CT2 grape preservative (provided by the National Agricultural Products Preservation Engineering Technology Research Center) at the amount of 1 pack per catty, seal the plastic wrap and store in a cold storage at 0°C. .

Embodiment 2

[0017] Example 2 Under the condition of no dew on a sunny day, 8 mature wolfberries with stalks were selected. After harvesting, 1 kg of wolfberries were put into food-grade plastic trays, and placed in a refrigerator at 0°C within 1 hour to soak the fruits with 40% alcohol 3 min, and then intercooled in the cold storage at 0°C for 20 hours, so that the temperature of the wolfberry reached 0°C, and then packed into PE fresh-keeping plastics produced by the National Agricultural Products Preservation Engineering Technology Research Center (Tianjin) with a thickness of 20 μm and a length of 110 cm×width of 60 cm. In the film, each film has a loading capacity of 1.5kg, and then puts CT2 grape preservative (provided by the National Agricultural Products Preservation Engineering Technology Research Center) at the amount of 2 packs per catty, seals the plastic wrap, and stores it in a cold storage at 1°C That's it.

Embodiment 3

[0018] Example 3 Under the condition of no dew on a sunny day, select 9 mature wolfberries with stalks and harvest them, put 3 kg of wolfberries into food-grade plastic trays, put them in a refrigerator at 1°C within 5 hours, and soak the fruits with 50% alcohol for 1 minute , and then intercooled with cold air at -1°C for 24 hours, so that the wolfberry temperature reached 1°C, and then put it into a 30 μm thick, 120 cm long × 50 cm wide PE plastic wrap produced by the National Agricultural Products Preservation Engineering Technology Research Center (Tianjin) , each film is filled with 2kg, and then 2 packs per catty are put into CT2 grape preservative (provided by the National Agricultural Products Preservation Engineering Technology Research Center), sealed with plastic wrap, and stored in a cold storage at 2°C.

Abstract

The present invention relates to a fresh-keeping method for fresh eating medlar. The method comprises: picking fresh fruits with the carpopodium, carrying out pre-cooling, and storing by a fresh-keeping film. According to the present invention, the fresh medlar fruits treated by the method of the present invention can be stored for a long time, the keeping time is 6-8 months, the good fruit rate of the medlar can be maintained to more than 95%, the appearance and the internal components of the treated fruit are the same as the appearance and the internal components of the fresh medlar, the fruit is fresh, the carpopodium is green; the fresh-keeping method of the present invention has characteristics of low cost, convenient operation and practical technology, and can be used for long-term storage and long-distance transportation of the fresh eating medlar.

Description

[0001] technical field [0002] The invention relates to a fresh-keeping method for fresh plant fruits, in particular to a fresh-keeping method for fresh goji berries. [0003] Background technique [0004] Lycium chinense (Lycium chinense) is a plant with the same source of medicine and food. The fruit can be eaten fresh or dried and used as medicine. It is a good nutritional tonic. After a lot of research by scientists, it has been proved that wolfberry contains protein, vitamins, amino acids and large and trace mineral elements needed by the human body. With the separation, extraction and identification of biologically active ingredients such as Lycium barbarum polysaccharides, β-carotene and unsaturated fatty acids unique to Lycium barbarum fruit, the medicinal and food homology of Lycium barbarum is more prominent. [0005] With the improvement of people's living standards, goji berry, which has both medicinal and edible effects, is favored, and the planting area ...
