Effect of (-)-epigallocatechin gallate (EGCG) and (-)-epicatechin (EC) at different concentrations (100-300ppm) on frying stability of soybean oil blended with tea seed oil was studied. Thermal stability of the blended oil increased with the addition of EGCG and EC, especially with increasing concentrations. Frying induced degradation of tocopherols and phenolics of oils, particularly tocopherols. Incorporation of catechin derivatives could retard tocopherol decomposition and formation of polar materials. The highest frying stability was found for the oil added with EC at 300ppm. When the oil added with EC (300ppm) was used to prepare fish crackers, lowered lipid oxidation of the resulting crackers than those prepared using the control oil was noted throughout 12weeks of storage. EC could be effectively used as natural antioxidant in frying oil with carry through effect to enhance oxidation stability of the fried foods during a storage.
