Preservation of gallic acid and methyl gallate on purified Kilka fish oil oxidation by Rancimat
Abstract Kinetic analysis of gallic acid and methyl gallate in purified Kilka oil was studied in the concentration, range 200–1600 ppm, during autooxidation in Rancimat test at 60°C. The stabilization factor (F), the oxidation rate ratio (ORR), the activity (A), and the mean rate of antioxidant cons...
