The traditional method with amino acid analyzer is accurate but time-consuming and rather expensive in cost. Therefore, the quick and less-expensive dye-binding method was evaluated for its accuracy. Hybrid corn varieties Tainan No. 5 and Tainan No. 11 and No. 13 double cross opaque-2 lines were used for comparing the two methods of lysine determination. |
