Abstract

This study evaluates the changes in total phenolic content, total anthocyanin content and turbidity withrespect to various processes that are used during the clear red grape juice production. Advancedclarification of grape juice was carried out by ultrafiltration using 50 kDa cut-off membrane. Ultrafiltrationcaused significant lowering in total phenolic content and turbidity value as 30.9 and 99.0 %, respectively.Only 10.5 % total anthocyanin content were lost during the process
