Effects of Co⁶⁰γ-Rays on Fried Bean Curd (VI)

Examination of Heated Soybean Oil and the Oil Absorbed in the Outer Crust of the Bean Curd in Relation with the Irradiation Odor

Abstract

An irradiation odor of the oil extracted from the crust of irradiated (37times;10⁶γ) fried bean curd was found to be much stronger than that of the irradiated heated-soybean oil. Chemical, paper chromatographic and ultraviolet spectrophotornetric an-alyses of these oils revealed some effects of irradiation. The results also indicated that the chemical compositions of the two oils differred remarkably from each other.
