Abstract: Disclosed are a method for preparing a linseed polysaccharide having antiviral activity and immunological activity, food and healthare products and methods of treatment using the linseed polysaccharide. The method comprises the steps of: using the linseeds as raw materials, pulverizing the linseeds, separating the husks from the kernels of the linseeds, extracting by the microwave-assisted hot water extraction, deproteinizing by the Sevage method, carrying out ethanol precipitation, and freeze-drying to obtain the linseed crude polysaccharides, then carrying out ion-exchange column chromatography, Sephadex gel column chromatography, and ultra-filtration so as to obtain the linseed triple-helix polysaccharides.

Abstract: Disclosed is a method for synthesizing diglyceride using a bubble column reactor. The method comprises the steps of: an immobilized enzyme is placed on the bearing mechanism of the bubble column reactor; a hot bath mechanism is actuated to heat the reactor body to 55-75° C.; glycerol, fatty acid and water are added into a feed chute, preheated to 55-75° C.

Abstract: Disclosed is a method for preparing a medium-long-chain triglyceride using a packed bed reactor, and belongs to the technical field of deep processing and modification of lipids. In the present invention, a medium-chain fatty acid triglyceride and a lipid as raw materials are subjected to a catalyzed transesterification using an immobilized enzyme having a 1,3 position-specificity being capable of catalyzing a transesterification reaction in the packed bed reactor to prepare a medium-long-chain triglyceride; the transesterification product is then subjected to an ethanol extraction to obtain a highly pure medium-long-chain triglyceride product; and the product remaining after the extraction useful as a raw material is backfilled into the reactor and continues to participate in the next batch of preparation of a medium-long-chain triglyceride.
