1. Choose dates to see the color and shape. First look at whether the jujube color is purple, the particles are large and uniform, and then look at whether the fruit shape is short and round, with few wrinkles and shallow traces; The skin is thin and the core is small, and the meat is thick and thin; If there are many wrinkles, deep traces and concave fruit shape, it is a dry product with poor meat quality and immature fresh dates.

2. Check whether there are holes in the dates. If there is a hole, it may be a wormhole. See if there are brown powdery objects around the hole. If there is, it means that the jujube was eaten by insects. Can't eat.

3. Open the taste. If the taste is sweet enough, knead the jujube with your hands. If it feels slippery but not loose, it means that the quality is fine and tight, and the jujube is dry and small; If the sweetness is poor and the taste is sour, the quality will be poor, soft and rough if it is pinched by hand. If it is wet and sticky, it means that the jujube is wet, not durable and easy to rot and deteriorate.
