Abstract
In spite of various bio-functionalities of chitosan, the effects in vivo were still ambiguous because of its low absorption on organism. Therefore, chitosan oligosaccharides (COSs) are necessary to elucidate for an efficient utilization in vivo. COSs were prepared from chitosan using ultrafiltration membrane enzymatic reactor system with MWCO (molecular weight cut-off) 3,000 Da of membrane. Calcium absorption accelerating effect using COSs was examined by two methods, in vitro and in vivo. In vitro experiment, calcium absorption by the addition of COSs in a mixture solution of calcium and phosphate was higher approximately
최근 다양한 기능성의 발현으로 크게 각광받고 있는 키토산 올리고당을 이용하여 칼슘의 체내 흡수율의 효과에 미치는 영향을 in vitro 및 랫트를 이용한 in vivo에 의해 검토하였다. 1. 제조된 키토산 올리고당은 3당류
