Method for delaying aging and yellowing of broccoli

Abstract

The invention belongs to the technical field of the storage and fresh keeping of fruits and vegetables, and specifically relates to a method for delaying the aging and yellowing of broccoli. The method adopts a compound solution of glycine betaine and arginine to soak postharvest broccoli and includes the following steps: (1) compounding 10 mM of the glycine betaine and 1 mM of the arginine according to the mass ratio being 3: 7 so as to obtain the compound solution; and (2) soaking the surfaces of the postharvest broccoli into the compound solution obtained by the step (1) for at least 15 min, taking the postharvest broccoli out to perform bagging after natural air-drying, and storing the postharvest broccoli in a cold storage with the temperature being 4 + / - 0.05 DEG C. The yellowing speed of the broccoli processed by the compound solution is slower than that of the broccoli individually processed by the glycine betaine or individually processed by the arginine, and the efficiency ofdelaying aging can be higher.

Description

technical field [0001] The invention belongs to the technical field of fruit and vegetable storage and preservation, and in particular relates to a method for delaying aging and yellowing of broccoli. Background technique [0002] Broccoli, also known as broccoli and green cauliflower, is an annual plant of the genus Brassica in the family Brassicaceae. It is a very popular vegetable with delicious taste, rich nutrition and high medicinal value. It is widely used in the north and south of my country. are widely planted. Because of its crisp taste and rich nutritional value, it is very popular among people. But broccoli is very easy to age and turn yellow at normal temperature, rot and deteriorate, which seriously affects its commodity value and nutritional value. Thus, using proper treatments can delay the yellowing of broccoli and extend its shelf life. [0003] The postharvest physiological characteristics and causes of rot of broccoli are as follows: [0004] 1. Respir...

AI Technical Summary

Problems solved by technology

Physical fresh-keeping technology is relatively easy to implement, and the operation is relatively simple, but the effect of fresh-keeping and delaying yellowing is not ideal; chemical treatment uses chemical preservatives for fumigation, spraying or soaking, and it is necessary to strictly control the amount of chemicals used and pay attention to the safety of the chemicals. And the treatment effect is not ideal
