✦ Synopsis
The effects of ?-irradiation on the browning reaction in the model system of fructose-phenylalanine solution were investigated. The optical absorption recorded for irradiated and heated solutions of fructose-phenylalanine was different from those of only irradiated or only heated solutions.
T o explain the role of carbonyl compounds formed during radiolysis of fructose and phenylalanine investigations of their N-methyl-benzothiazolone hydrazone hydrochloride derivatives were undertaken. It has been found that as a result of irradiation of the model system mainly aliphatic aldehydes are formed, besides a small amount of cyclic aldehydes. However during heating the contribution of aliphatic and cyclic products is similar.
