Problems solved by technology

[0006] At present, there are large differences in the sugar content of stored persimmons, and it is impossible to achieve precise temperature-controlled storage of persimmons with different sugar levels, and the precise fresh-keeping method for physiological regulation and coordinated regulation of rot or mildew is still unclear

Embodiment 1

[0033] Embodiment 1: the preservation of low-sugar persimmon fruit

[0034]The first choice is to pick persimmons with inherent fruit shape, hardness, color and flavor that meet the storage requirements. The fruit surface is required to be clean, free from damage, no pests and diseases, and no foreign impurities. Each fruit is packed in a foam net, and the outer packaging is standard Fruits can be packed in cartons, or in clean, porous plastic boxes, 8-10 kg per box. Near-infrared non-destructive online grading was carried out, and low-sugar persimmon fruits (10%2 , the ethylene formation rate is 0.82 μL·kg -1 h -1 .

[0035] Effect comparison: Stored according to the above conditions, refrigerated for 80 days without high-concentration 1-MCP and natamycin antiseptic treatment. After refrigerated for 80 days and stored for 5 days, the mildew rate of persimmon fruit was 15.25%, and the hardness was 17.13 kg / cm 2 , the ethylene production rate was 1.15 μL·kg -1 h -1 .

Embodiment 2

[0036] Embodiment 2: the fresh-keeping of middle and high sugar content persimmon fruit

[0037] The first choice is to pick persimmons with inherent fruit shape, hardness, color and flavor that meet the storage requirements. The fruit surface is required to be clean, free from damage, no pests and diseases, and no foreign impurities. Each fruit is packed in a foam net, and the outer packaging is standard Fruits can be packed in cartons, or in clean, porous plastic boxes, 8-10 kg per box. Near-infrared non-destructive online grading was carried out, and medium and high sugar content persimmons (12%2 , the ethylene formation rate is 0.78 μL·kg -1 h -1 .

[0038] Effect comparison: Stored under the above conditions, no high-concentration 1-MCP and natamycin antiseptic treatment was carried out after refrigerated for 90 days. After being refrigerated for 90 days and stored for 3 days, the mildew rate of persimmon fruit was 15.73%, and the hardness was 16.36 kg / cm 2 , the ethy...

Abstract

The invention discloses a green and precise fresh-keeping method for keeping persimmons crisp and mildew-proof and its application. The method is to carry out non-destructive grading of the sugar content of the harvested persimmons, pre-cool them at 0±0.5°C for 8-12 hours, and at the same time Treat with 0.5~1.0μL / L 1-methylcyclopropene modified atmosphere treatment, acclimate at -1.3~-1.0℃ for 8~12 hours at low temperature, and then at precise temperature control -0.8~-0.5℃ or -0.5~-0.2 After storage at ℃ for 75-90 days, the storage temperature was adjusted to 0-0.5 ℃ for 48-72 h, and at 10±0.5 ℃ for 24-36 h. Fumigate again with 2.5-7.5 μL / L high-concentration 1-MCP, wash with natamycin preservative solution for 1-3 minutes, and dry the surface for personalized packaging and sales. Through the combination of the above technologies and process parameters, the crispness of persimmon fruit can be significantly maintained and the quality can be improved.

Description

technical field [0001] The invention relates to a fresh-keeping technology for post-harvest persimmons, in particular to a crisp, anti-corrosion and green fresh-keeping method for post-harvest persimmons with precise sugar content classification, precise 1-MCP treatment, precise temperature storage technology, and precise natamycin treatment. Background technique [0002] Persimmon fruit is rich in nutrition, unique in flavor, and has high edible value and medical care value. It is one of the five famous fruits (grape, citrus, banana, apple, and persimmon) in China. Every 100 g of persimmon fruit contains 12-14 g of sugar, 0.44-0.79 g of protein, 0.57 g of fat, and 0.46-0.60 g of soluble pectin, and contains a variety of mineral elements and amino acids, which are rich in nutrients; Medicinal value, with clearing away heat and moistening lungs, promoting body fluids and quenching thirst, eliminating phlegm and relieving cough, mainly treating dysphoria and thirst, dryness of...
