The invention provides sleep-aiding
solid food based on a spina date seed composite formula and a preparation method of the sleep-aiding
solid food. The food comprises the following components in parts by weight: 20-40 parts of spina date seeds, 15-25 parts of longan
aril, 25-35 parts of raw oysters, 10-20 parts of poria cocos, 4-8 parts of liquorice, 1-3 parts of
ginseng, 3-7 parts of roses and food-grade auxiliary materials. The preparation method comprises the following steps: pretreating raw materials; the spina date seeds are subjected to water decoction and
ethanol microwave extraction, the raw oysters are subjected to alkaline
proteolysis, and the roses are subjected to differential compound extraction such as supercritical CO2 extraction; mixing and concentrating; and finally, mixing with auxiliary materials to form a
solid beverage, a gel candy or a tablet candy. Through a scientific compound and compound extraction process, the extraction rate and the product content of active ingredients such as jujuboside and
ferulic acid are remarkably improved, and multi-target synergistic sleep aiding is realized; by optimizing forming and packaging processes, the taste, the stability and the portability of the product are effectively improved, and the sleep-aiding
solid food which is convenient to take and exact in effect is provided.
