In the process of wolfberry acquisition, the evaluation of the quality of wolfberry mainly includes the following five aspects: (1) the size of a single wolfberry, (2) the color of a single wolfberry, (3) the integrity of the wolfberry fruit, (4) whether there are foreign objects, (5) Chemical quality of wolfberry (such as sugar content). Among them, (1) and (2) belong to sensory quality, (3) and (4) belong to physical quality, and (5) belong to physiological and biochemical quality.

In the traditional process, the sorting method for the size of wolfberry mainly adopts the sieving method, which is simple but rough in classification.
