Abstract

The invention belongs to the technical field of nutrient extraction and application, and particularly relates to a method for extracting cordyceps polysaccharide from cordyceps flowers and applicationof the cordyceps polysaccharide in wheaten food production. According to the preparation method, the effect of high cordyceps polysaccharide extraction rate is achieved by the steps of pulverization,crushing, extraction, concentration and drying in sequence; before preparation, embedding and coating treatment are performed to form a three-layer structure including an outer layer, a middle layerand an inner layer, so that the innermost cordyceps polysaccharide is still stable in structure under high-temperature cooking of cooked wheaten food. The method has the advantages that the extractionprocess is reasonable and effective, the extraction rate is high, the extraction operation is simple and convenient, the high-temperature resistance of the three-layer structure of the outer coatinglayer, the middle embedding layer and the inner cordyceps polysaccharide is high, the polysaccharide structure stability is good during noodle making and eating, the efficacy loss is small, and the coating and embedding processes are simple and efficient.

Description

technical field [0001] The invention belongs to the technical field of extraction and application of nutrients, and in particular relates to a method for extracting Cordyceps polysaccharide from Cordyceps flowers and its application in noodle making technology. Background technique [0002] Cordyceps flower, also known as Cordyceps militaris, is rich in Cordyceps polysaccharides, and Cordyceps polysaccharides have anti-tumor, hypoglycemic and blood lipid-lowering effects, so Cordyceps polysaccharides have been initially used in food, pharmaceutical and other industries. On the other hand, when Cordyceps polysaccharide is used in food applications, if it encounters high-temperature cooking, its polysaccharide structure will not be stable enough. The health benefits will be greatly reduced, so a new application method is urgently needed in the market to ensure that the Cordyceps polysaccharide can remain stable in a high-temperature cooking environment, so as to expand its app...
