Abstract

The invention discloses a preparation method of quick-frozen Lycium barbarum. The method is characterized by comprising the following steps: cooling ice water; draining; quick-freezing. The prepared quick-frozen Lycium barbarum has bright red color, color consistency, no individual adhesion and uniform size; the preparation method effectively maintains the color and flavor of Lycium barbarum, and extends the storage period; and the bacterial colony count / g is less than or equal to 10000, and fecal coliform (MPN / 100 g) is less than 3. The preparation method of quick-frozen Lycium barbarum effectively solves the problem of serious effective component loss in storage process, retains the nutritional ingredients to the maximum and keeps the appearance and quality of the quick-frozen Lycium barbarum the same to the fresh ones, so as to ensure that people can always eat fresh Lycium barbarum.

Description

technical field [0001] The invention relates to the field of food processing, in particular to a preparation method of quick-frozen wolfberry. Background technique [0002] Lycium barbarum is a multi-branched shrub plant of the genus Lycium barbarum in the family Solanaceae. It is 0.5-1 meter high and can reach more than 2 meters when cultivated. The fruit is called wolfberry, and the young leaves are called wolfberry head. The common species is Lycium chinense Miller, and the main medicinal species is Lycium barbarum L.. [0003] Lycium barbarum fruit is intermittently matured. In production, it is generally divided into: spring fruit wolfberry, summer fruit wolfberry and autumn fruit wolfberry. The fruit that matures from June to early July, that is, the fruit of the old eye branch is the spring fruit Lycium barbarum; the fruit that comes from the spring branch of the year from early July to August is called the summer fruit; the fruit that matures from September to Octob...
