Abstract
In this study, the characteristic qualities of whole soymilk were examined based on differing hydrolysis condition. The results showed that as the concentration of enzyme preparation(KMF-G) increase, $^{\circ}Brix$, calcium-binding capacity, and the content of free amino acid components also increased. Additionally SDS-PAGE analysis revealed a similar pattern of in the molecular weight of proteins at enzyme preparation concentration 0.20 and 0.35%(w/w). The quality of whole soymilk hydrolysate was shown to be best at a enzyme preparation(KMF-G) concentration of 0.20%(w/w) and hydrolysis time of 60 min. When sterilized at 115, 130 and $145\;^{\circ}C$ for 15 sec each the change in whole soymilk quality was not substantial. Based on the above results, a 0.20%(w/w) enzyme preparation(KMF-G) concentration and 60 mim hydrolysis time was determined to be the optimal hydrolysis condition for whole soymilk. It is anticipated that soymilk hydrolysis will a food material that is diverse in its application and uses.
본 연구에서는 전두유의 가수분해 조건에 따른 품질 특성을 조사하였다. 그 결과 효소제(KMF-G) 농도가 증가함에 따라 전두유 가수분해물의 당도, 칼슘 내인성, 및 총 유리아미노산 함량은 증가하였으며, SDS-PAGE 분석 결과 단백질의 분자량 변화는 0.20%(w/w)와 0.35%(w/w) 농도에서 유사한 패턴을 나타냈다. 전두유 가수분해물은 효소제(KMF-G) 농도 0.20%(w/w), 가수분해 시간 60분에서 가장 우수하게 나타났다. 전두유 가수분해물을 115, 130 및 $145^{\circ}C$에서 15초간 살균하였을 때 품질변화는 크지 않았다. 이상의 결과 전두유의 가수분해 최적조건은 효소제(KMF-G) 농도 0.20%(w/w), 가수분해 시간 60분으로 설정할 수 있었으며 식품소재로의 다양한 활용이 기대된다.
