HMF is one of the chemical substances (intermediate)produced during browning process, thus serving as a goodindicator of Maillard reaction. UV-C treated samples showed no signif-icant changes in HMF content except U60, when comparedwith the control. In contrast, the maximum increase in HMFcontent was observed in thermal treated samples (3.96 mg/l)when compared with control (2.20 mg/l).
