OPTIMIZATION OF HYDROTHERMAL TREATMENT ON ANTINUTRITIONAL FACTORS IN SELECTED PIGEON PEA VARIETY IN MYANMAR

Abstract

The presence of anti-nutritional factors negatively affects the bioavailability of protein, calcium, iron and zinc. This study was conducted with the aim of optimizing the effect of hydrothermal treatment and drying on antinutritional factors and protein content in pigeon pea. The Central Composite Rotatable Design of RSM was applied to optimize the hydrothermal condition for reducing antinutritional factors. The experiment was conducted with 2 independent factors (hydrothermal treatment and drying and drying) at five levels ( ̶ α, ̶ 1, 0, 1, + α). The optimum conditions for the lowest antinutritional factors in pigeon pea were 11-minute hydrothermal treatment and drying and 2-h drying.
