Abstract
In order to utilize protein hydrolysate produced from hoki (Johnius Belengeri) frame among many different fish processing wastes, hoki frame peptide (PHFP) and phosphorylated hoki frame peptide (PHFP) were prepared, and their calcium absorption accelerating effects were investigated in comparison to control and casein phosphopeptide (CPP). In in vitro experiment, HFP and PHFP inhibited calcium phosphate formation as high as 1.5-fold and 2.5-fold, respectively, comparing to control, In addition, the inhibition rate of calcium phosphate precipitation as increasing concentrations of HFP and PHFP was risen and was similar to that of CPP at 2.0 mg/ml of PHFP concentration, In in vivo experiment using the rats, the groups fed HFP and PHFP indicated significantly increased calcium content in the femur. In particular, the calcium content in the small intestine of the rat fed PHFP was higher than that of control group by approximately
수산가공공장에서 부산물로 대량 생산되고 있는 민태 frame 단백질로부터 회수된 펩타이드의 이용성을 탐색할 목적으로 민태 frame 단백질 유래 펩타이드와 이를 인산화시킨 펩타이드에 대한칼슘흡수 촉진효과를 칼슘의 침전형성 저지율을 이용한 in vitro 실험과 칼슘 결핍 흰쥐를 이용한 in vivo실험으로 검토하였다. 먼저 in vitro 실험에서 칼슘의 침전형성 반응시간의 변화에 따른 상충액중의 칼슘농도는 민태 frame 펩타이드(HFP)와 인산화시킨 펩타이드 (PHFP)를 첨가한 경우 대조군보다 각각 약 1.5배 및 2.5배 높은 것으로 나타났으며, 펩타이드의 첨가농도에 따른 실험에서도 HFP는 농도가 1.0mg/ml일 때 가용화율이
