摘要：In this study, a number of the most common methods used in assessing the efficiency of soybean heat treatment were compared. All the methods proved to be useful in assessing the efficiency of heating soybean seeds and soybean products. However, considering the sensitivity, precision, time consumed, and the effectiveness of determination of the characteristics of the samples, the use of the bromocresol purple index (BCPI) appears to be justified. The BCPI method turned out to be universal, allowing distinguishing unheated (BCPIBSM < 70 mg·g−1), under-heated (70 mg·g−1 < BCPI BSM < 130 mg·g−1), properly heated (BCPI BSM = 130–140 mg·g−1), and over-heated samples (BCPI BSM > 140 mg·g−1).
