Two levels of antioxidants, 0.02% and 0.002%, were added to a concentrated fish product. Two ways of incorporating antioxidants into fish oil were studied. The oxidation rate of the samples was measured by using an oxygen analyzer and the thiobarbituric acid test. The concentrated fish prepared from fresh mullet was stored for 0 hr, 48 hr, and 96 hr. The use of antioxidants in a vegetable oil carrier did significantly slow the breakdown reaction of fish oil and lowered the oxidation rate of the sample. When vegetable oil was used to serve as an antioxidant carrier, the high level of antioxidant (0.02%) stabilized the fatty product more efficiently than the lower level (0.002%) did. At the level of 0.02% antioxidants, using soybean oil to serve as antioxidant carrier, the fish product was quite stable during storage under the conditions of this study.
