Periodic UV-C light treatment for reducing the formation of free fatty acids in crude palm oil during storage

The formation of free fatty acids (FFA) during long term storage of crude palm oil (CPO) is inevitable, and it can reduce the quality and losing the CPO. Therefore, this study aims to evaluate the effect of UV-C light on lipase enzyme deactivation and the effect of periodic UV-C light treatment t...
