β-glucan이란? | 보리배유의 세포벽은 특징적으로 β-glucan이 약 75% 함유되며 arabinoxylan 약 25%, 그리고 소량의 glucomannan, cellulose 등을 포함하고 있다[3]. β-glucan은 효모의 세포벽, 버섯류, 곡류 등에 존재하는 식이섬유로 포도당이 β-(1→3, 1→4) glucoside 결합을 한 다당류의 일종이다. β-glucan은 고분자 특성으로 인하여 수용액 상에서 높은 점성을 나타내며[4], 혈당을 낮추고 혈중 콜레스테롤을 감소시키는 긍정적 생리작용을 나타내는 것으로 알려져 있다[5, 6, 7]. | |
β-glucan의 단점은? | 한편 β-glucan은 물에 잘 녹지 않는 단점을 가지고 있는데 이로 인하여 식품에 적용 시 많은 제약이 따르게 된다[10]. 이를 개선하기 위해 물리적, 화학적 처리를 통해 원래 가지고 있던 성질을 변화시켜 이용성을 개선할 필요성이 있으며, 그 중 화학적 변성으로 초산 혹은 옥테닐 호박산 등과 같은 화학적 치환기를 부가하는 방법이 있다[11]. | |
