According to Indonesian National Standards, the parameter of quality test of cooking oil consists of many aspects, accompanied by its various methods. Both the parameter and methods can't be done simultaneously. It takes a long time and quite expensive costs. Through this paper, proposed that the active optic parameter is an alternative parameter of cooking oil which experiencing some treatments.
