Problems solved by technology

[0003] Raspberries have a good taste, are tender and juicy, but due to their soft skin and strong respiration, they are difficult to store, transport and keep fresh
At present, the preservation of raspberries mostly adopts the method of physical preservation, but the physical preservation method has the disadvantages of high cost, complicated equipment, and difficult operation

Abstract

The invention discloses a fresh-keeping method of raspberries. The method comprises the following steps: selecting healthy raspberry fruits which are uniform in size, uniform in color, free from disease and pest and free from damage; conducting washing with flowing water, and conducting soaking washing with acidic electrolyzed water; carrying out compound film coating liquid treatment on the raspberry fruits after the soaking washing with the acidic electrolyzed water; conducting draining, and conducting spontaneous modified atmosphere packaging with 0.015mm thick polyethylene film bags; and conducting storing in a 4 DEG C cold storage. The raspberry fruits treated by the method can be stored for 25 days, and the method effectively inhibits the quality deterioration problem caused by the fruit decay during the storage and preservation process of picked raspberry fruits, and improves the storability of raspberry fruits.

Description

technical field [0001] The invention relates to the field of fresh-keeping of fruits and vegetables, in particular to a fresh-keeping method of raspberries. Background technique [0002] Raspberry is a perennial deciduous shrub-type fruit tree of the Rosaceae Rubus genus, also known as tray, Rubus, etc., and Chinese herbal medicine calls it raspberry. Raspberries are rich in 21 kinds of amino acids and multivitamins necessary for the human body, of which eight kinds of amino acids cannot be synthesized by the human body but play an important role in human metabolism. Raspberry is also rich in plant SOD that can be absorbed by the human body, natural anticancer substance tannic acid, natural aspirin salicylic acid and a large amount of natural weight loss substance raspberry ketone. [0003] Raspberries have a good taste and are tender and juicy. However, due to the soft skin and strong respiration of berry fruits, there are problems in storage, transportation and preservati...
