Molecular structure, physicochemical properties, and in vitro digestibility of starch from Korean rice cultivars for special uses (Baegjinju 1, Hanareum, Deuraechan, and Goami 4) were investigated. The starch from Baegjinju 1 had the lowest amylose content (9.7%) and Hanareum, Deuraechan, and Goami ...

쌀은 아밀로스 함량에 따라 어떻게 분류되는 가? | 3%의 아밀로스를 함유하며 찰벼를 제외한 자포니카 쌀품종 내 전분은 8-37%의 아밀로스와 나머지는 아밀로펙틴으로 이루어져 있다. 일반적으로 쌀은 아밀로스 함량에 따라 waxy(1-2%), 저 아밀로스(7-20%), 중간 아밀로스(20-25%)와 고아밀로스(25% 이상)로 분류된다(5). | |
천천히 소화되는 전분은 어떤 효능을 갖는 가? | 전분은 소화되는 속도에 따라 크게 3가지로 분류 할 수 있으며, 빨리 소화되는 전분(rapidly digestible starch, RDS), 천천히 소화되는 전분(slowly digestible starch, SDS), 소화되지 않는 전분(resistant starch, RS)이 있다(6). 이들 중 SDS는 소장에서 느리지만 완전히 소화됨으로써 포만감을 오래지속 시켜주며 주로 당뇨병과 관련하여 건강에 유익하다고 알려져 있다. 또한 RS는 소장에서는 소화되지 않지만 대장에서 완전히 또는 부분적으로 발효됨으로써 대장 환경에 유익한 환경을 미치며 고지혈증, 심혈관계질환 등에도 좋은 영향을 미치는 것으로 알려져 있다(7). | |
쌀은 무엇인가? | 쌀(Oryzae sativa L.)은 밀과 옥수수와 함께 세계 3대 주요 곡물 중 하나로 동남아시아를 비롯한 여러 국가에서 주식으로 이용되고 있는 주요 에너지 공급원이다(1). 우리나라는 1970년대 이후 산업화 시대에 따른 생활환경의 급속한 변화로 식생활의 형태가 동물성 식품 위주의 서구화로 변화되면서 쌀 소비량이 감소하기 시작하였다(2). |
