Abstract
Disclosed is an ultrasonic composite acidic water extraction method for apolysaccharide and cordycepin in, which falls within the technical field of food processing. The method comprises: picking, washing, drying, pulverizing and degreasingfruiting bodies to obtain adry powder; then immersing same in a prepared diluted hydrochloric acid solution to perform three cycles of ultra-low temperature freezing and microwave defrosting, and at the same time using low-frequency ultrasonic waves to carry out assisted stirring and extraction; then subjecting an extract to evaporation and concentration treatments; and finally, performing freeze-drying on the extract to collect a dry powder of a water extraction product. The amount of an additive used in the method meets domestic and foreign usage requirements of food additives, and the operation is simple, practical and uses a combination of chemical and physical methods, thereby saving time and being highly efficient.
