Abstract

The contents of the several antinutritional factors and lipoxygenase activity of 19 soybean varieties recommended for cultivation in Korea were analyzed. The ranges of raffinose and stachyose contents, which are the flatulence factors, were $0.74{\sim}1.58%\;d.b.\;and\;3.34{\sim}5.30%d.b.$, respectively and the total amount of these sugars was high in the varieties of Hill, Baekun and Jangbaek. The contents of trypsin inhibitor and phytate phosphorus in the soybean varieties ranged from 21.2 to 37.0 TI/g, d.b. and from 337 to 605mg%, d.b. respectively. The lipoxygenase activity of $163.6{\sim}403.5unit$ was shown in the 19 soybean varieties, and Padal, Jangbaek and S-133 were the varieties with the higest activity.

장려품종 콩 19종에 함유된 몇 가지 영양저해 인자의 함량과 리폭시게나아제의 역가를 조사하였다. 복부팽만인자인 라피노오스와 스타키오스의 함량은 각각 $0.74{\sim}1.58%\;3.34{\sim}5.30%$ 범위이었으며 힐, 백운, 장백 등의 품종에서 이 두 종류 당의 합량이 높았다. 콩에 함유된 트립신 저해제는 $21.2{\sim}37.0mg$ TI/g, 피트산 형태로 존재하는 인은 건물 100g 당 $337{\sim}605mg$ 정도로 품종에 따라 큰 차이를 보였다. 한편, 콩에 함유된 리폭시게나아제의 역가는 $163.6{\sim}403.5unit$로 팔달, 장백, S-133등의 품종이 높은 값을 나타내었다.
