Problems solved by technology

The ripening period of blueberry fruit is in the hot and rainy season from June to August. Post-harvest respiration is strong, various physiological metabolisms are accelerated, and storage resistance is low. Corrupted by fungal infection, it can only be stored for 3-7 days at 20-30°C after harvest, which greatly limits the fresh sale period of the fruit and the needs of consumers

Embodiment 1

[0025] Embodiment 1, carry out according to the following steps:

[0026] (1) Picking and selection of blueberry fruit: In the Baima Experimental Base of Lishui District, Jiangsu Province, 8-9 mature "peak" blueberry fruits were picked, and blueberry fruits with uniform size, uniform maturity, and no mechanical damage were selected from them. For two groups, the experimental group and the control group, each placed in a closed PP (polypropylene) plastic box;

[0027] (2) Use 10 μmol / L methyl jasmonate (MeJA) to fumigate the blueberry fruit of the experimental group, put the MeJA solution in a closed plastic box, let it evaporate naturally to the required concentration, MeJA is analytically pure, and the treatment time 10 hours, the treatment temperature is 20°C; the control group is also put into blank distilled water, the treatment time is 10 hours, the treatment temperature is 20°C;

[0028] (3) After processing, open the lid and ventilate naturally at 20°C for 1 hour;

Abstract

The present invention provides a blueberry fruit storage and preservation method. Blueberry fruits with a uniform size, a consistent maturity and no mechanical damages are chosen and directly put into an airtight plastic box. 1-100[mu]mol / L of methyl jasmonate (MeJA) is used to treat the blueberry fruits for a treatment time of 10 h and at a treatment temperature of 20 DEG C, and the treated blueberry fruits are placed at 0-4 DEG C for storage. The blueberry fruit storage and preservation method effectively slows down the ripening and senescence of the blueberry fruits during the storage process, maintains a good fruit quality, and extends the storage period. As a natural agent, the MeJA applied in the blueberry fruit storage has advantages of being low in the processing cost, less in use amount, secure and easy to use, etc.

Description

technical field [0001] The invention belongs to a method for storing fruits and vegetables, and relates to a method for storing and keeping horticultural products, in particular to a method for storing and keeping fresh by screening the concentration of a preservative for blueberry fruit. Background technique [0002] blueberry( Vaccinium spp.), also known as bilberry and blueberry, is a perennial deciduous or evergreen shrub-like fruit tree of the genus Vaccinium in the family Ericaceae. The blueberry fruit is a berry, dark blue-purple, covered with hoarfrost, nearly round, with a moderately sweet and sour fruity taste, unique flavor, and high nutritional value. Blueberry fruit is rich in anthocyanins, ellagic acid, folic acid, flavonoids and other physiologically active ingredients, and these substances have anti-oxidation, remove harmful substances in the body, prevent cancer, prevent brain aging, protect capillaries, eliminate eye fatigue, Improve eyesight, etc. The r...
