PURPOSE: A silk peptide composition having diabetes improving functions is provided to improve diabetes using silk protein and offer a high molecular weight of silk peptide composition which is merely absorbed into the human body.CONSTITUTION: A functional food composition is produced by decomposition of protein and includes an average molecular weight of 10000-100000 of silk protein as an active ingredient. The silk protein is silk sericin or silk fibroin. The silk protein is silk fibroin. The silk protein decomposition is performed by a decomposition method selected from a group consisting of the decomposition of calcium salt solution, acid hydrolysis, decomposition by a mixture solution of calcium salt and ethanol and a combination thereof. The calcium salt is calcium chloride. The calcium salt removal is selected from a method consisting of dialysis, ultrafiltration, gel chromatography, electric desalting and a combination thereof.COPYRIGHT KIPO 2013본 발명은 당뇨에 개선 효과가 있는 고분자 실크 펩타이드의 구성물에 관한 것으로, 실크(견사)를 산 가수분해 방법 또는 염화칼슘을 이용하여 가수분해하여 동결 건조한 후, 분말상으로 제조한 고분자 실크 펩타이드 조성물로써, 본 발명의 실크 펩타이드의 분자량은 10,000~50,000 으로 체내에서 흡수되지 않아 혈당을 낮추는 기능성 식품 또는 의약품으로 개발하거나 각 성분에 대한 활성물질의 개발에 기여할 수 있다.
