Abstract

The invention relates to homogeneous fructan GEIN and application thereof, and belongs to the technical field of food processing. The homogeneous fructan GEIN disclosed by the invention has a sphere-like structure similar to starch particles, and the gelatinization characteristic of gastrodia elata starch can be remarkably improved. Moreover, the homogeneous fructan GEIN also has the effect of improving intestinal flora, can promote the growth of beneficial bacteria in intestinal tracts, and does not cause postprandial blood sugar rise. Discovery and separation of the homogeneous fructan GEIN fill the research blank of the regulation effect of gastrodia elata polysaccharide on starch gelatinization, provide a new active ingredient for deep development of gastrodia elata in the field of homology of medicine and food, and have important significance for development of gastrodia elata food and health care products.
