초록

Affinity chromatography법에 의해 해바라기씨 유래 $\alpha$-galactosidase정제를 수행하여 locust bean gum 증점 대체자원의 개발을 위한 기초연구로서 정제효소처리된 guar gum 과 locust bean gum의 구성당인 galactose와 mannose의 구성비율을 비교 검토하였다. 정제효소처리된 guar gum의 중점효과는 galactose와 mannose비율이 1 : 3.2일 때 가장 증가하였다. 이와같은 비율은 효소적 처리시간을 24시간으로 하였을 때 나타내었다. 해바라기씨 유래 $\alpha$-galactosidase처리에 의한 guar gum으로부터의 galactose의 유리가 증점효과에 영향을 미치는 것으로 사료된다. Xanthan gum과 guar gum의 혼합, xanthan gum과 guar gum 및 정제효소처리된 천연 유래 copra meal과의 혼합물에 대한 증점효과도 비교하였다.
