Abstract

Composition and pasting properties of endosperms of one common buckwheat (CB) and two tartary buckwheats (TB) grown in China were investigated. No differences were observed in proximate composition and amino acid content between CB and TB. Content of rutin in TB was 22-fold higher than that of CB. Among minerals, iron, calcium, and magnesium contents were higher in TB than CB, whereas zinc, manganese, and phosphorus contents were similar, Pasting properties measured with Rapid visco Analyzer revealed TB-2 cultivar had highest peak viscosity, trough, and breakdown, followed by TB-1 and CB. Setback of TB was about 2.2-fold greater than that of CB. Significant differences in color were observed between CB and TB, and among TB cultivars.

중국산 일반메밀 1종과 쓴메밀 2종의 껍질과 종피을 제거한 배유의 성분과 호화성질을 비교 분석하였다. 일반메밀은 쓴메밀 보다 상당히 크고 삼각형에 가까우나 쓴메밀-1종은 길쭉한 형태를 취하고 있으며, 쓴메밀-2종은 삼각형에 골이 깊숙이 파져 있는 형태를 보였다. 메밀쌀 가루의 일반성분과 아미노산 함량은 시료간에 차이가 없었고, 루틴 함량은 쓴메밀이 일반메밀보다 22배 이상 많이 함유하고 있었다. 무기질 함량 중 철, 칼슘과 마그네슘함량은 쓴메밀에서 높았고, 아연, 망간과 인 함량은 일반메밀과 쓴메밀 사이에 큰 차이가 없었다. 신속점도계에 의한 호화패턴을 살펴보면 쓴메밀-2종이 최고점도, 최저점도와 breakdown에서 가장 높게 나타났으며, 쓴메밀-1종은 breakdown이 가장 낮은 값을 나타내었다. 쓴메밀의 setback은 일반메밀보다 약 2.2배 컸다. 메밀가루의 색도는 일반메밀과 쓴메밀 사이에 또한 쓴메밀 사이에도 뚜렷한 차이를 보였다.
