Nostoc flagelliforme biscuit and preparation method thereof

The invention belongs to the technical field of food processing, and particularly relates to a nostoc flagelliforme biscuit and a preparation method thereof. Dried nostoc flagelliforme cells and nostoc flagelliforme exopolysaccharide solutions are added into the biscuit disclosed by the invention, so that the flavor of the biscuit is improved, at the same time, the biscuit also has the effects of improving the immunity of human bodies, resisting tumors, reducing blood lipid, reducing blood sugar and resisting viruses, and the health of the human bodies is promoted. The nostoc flagelliforme cells and the nostoc flagelliforme exopolysaccharide solutions are dried by a refrigerating and drying method, the technology can dehydrate heat sensitive materials more thoroughly, and dried samples are quite stable, so that the samples are convenient to store for a long term. Because the materials are dried under the state of refrigeration, compared with other drying methods, the changes of the physical structures and the molecular structures of the materials are minimal, the organizational structures and the appearance shapes of the materials are preserved better, the destruction rate of constituents of the nostoc flagelliforme cells is reduced, and original nutrient substances and flavor of the nostoc flagelliforme cells are better maintained.
