COMPOSITION CONTAINING SILK FIBROIN HAVING A HIGH MOLECULAR WEIGHT FOR LOWERING BLOOD SUGAR AND CHOLESTEROL, AND A METHOD OF PRODUCING SAME

摘要

The present invention relates to silk fibroin with a high molecular weight that has the property of lowering blood sugar and cholesterol, and a method of producing same. More particularly, the present invention relates to a composition which contains high-molecular silk fibroin having an average molecular weight (Da) of 190 000 to 400 000 as an active ingredient for lowering blood sugar and cholesterol, and a method of producing the composition. According to the present invention, high-molecular silk fibroin exhibits superior effects of lowering blood sugar and cholesterol than low-molecular silk fibroin peptide, and thus the composition of the present invention can be usefully used to manufacture functional foods and medicines for treating or preventing diabetes, obesity, or hyperlipidemia. Also, since a process of reducing the molecular weight of fibroin can be skipped which must be performed using conventional production methods of silk protein, the present invention has the advantage of reducing overall production costs.
