Oksidasi Minyak dalam Emulsi O/W : Mekanisme dan Pengendaliannya

2017
Oxidation can alter the flavor and nutritional quality of foods and produces toxic and color compounds, which make foods less acceptable or unacceptable to consumers. Consequently, lipid oxidation has been extensively studied in bulk fats and oils, and there is a fairly good understanding of the mechanisms and the factors that affect oxidation in such ...

Kinetika Oksidasi Minyak Ikan Tuna (Thunus sp) Selama Penyimpanan

2016
Tuna fish oil (Thunnus sp) contains omega-3 fatty acids. It can be easily damaged by oxidation during storage. The rate of oxidation can be estimated by zero or first order of reaction. This research aimed to study the oxidation reaction during storage by determining the amount of activation energy (Ea) and constant change (k).
