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 - 1.58% d.b. and 3.34 - 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 605 mg %, d.b. respectively. The lipoxygenase activity of 163.6 - 403.5 unit was shown in the 19 soybean varieties, and Padal, Jangbaek and S-133 were the varieties with the higest activity.
