| Abstract: | With pressed kBr disk technique the methyl-sulf amino-acid--the nutritious restrictive amino-acid of poultry was determined by internal standard-derivative infrared spectroscopy. The suitable internal standard--CaSO4 was selected, and peak height, peak area, first derivative and second derivative methods were used. In the determination, we selected undisturbed peak at 553 cm-1 as standard. The correlation coefficient of standard curve equation were in the range of 0.994-0.998. The result was satisfied. |
