Abstract: To make the nutritional ready-to-eat compound tablets of Pleurotus-eryngii, this experiment adopted spare parts of Pleurotus-eryngii. With fresh Pleurotus-eryngii residues as the main raw material, by single factor experiment and orthogonal experiment, the best formula was obtained through the sensory experiments. The best processing technology was obtained by adding jujube, hawthorn pulp, sugar, carrageenan, starch and other supplementary materials, using different drying methods, and through the determination of moisture, polysaccharides, flavonoids, and vitamin content in the product. The results showed that in the dry group the contents of polysaccharides, flavonoids and Vc were 1%, 16% and 0.19%, respectively, after microwave drying. The best formula appeared with hawthorn pulp 23%, date pulp 23%, sucrose 28%, starch 6%, and carrageenan 0.2%. Compared with the salable red peel of hawthorn fruit, the content of polysaccharide increased by 3.45%. The prepared instant compound tablets of Pleurotus-eryngii has unique flavor, rich nutrition and good quality.

Key words: Pleurotus-eryngii, polysaccharides, compound tablets of pleurotus-eryngii, drying method
