Stabilitas Foto-Oksidasi Campuran Minyak Ikan Patin (Pangasius Hypopthalmus) Dan Minyak Sawit Merah

---

Patin (Pangasius hypopthalmus) is one of the economically important freshwater fish in Indonesia. Patin waste as a by-product of smoking fish industry can be used as an ingredient of feed and oil in order to increase the community's economy. Polyunsaturated fatty acid in patin oil causes the oil susceptible to oxidation reactions. Therefore, fish oil needs to be added antioxidants. One of the natural antioxidants that can be applied is an antioxidant that found in red palm oil. This study aims to determine the effect of a mixture of patin and red palm oil on photo-oxidation stability. The treatments were ratio of patin and red palm oil which were stored in a different light condition. The treatments were P1 (100% patin oil, light control), P2 (100% patin oil, dark control), P3 (80% patin oil: 20% red palm oil, 10000 lux), P4 (50% patin oil: 50% red palm oil, 10000 lux), and P5 (20% patin fish: 80% red palm oil, 10000 lux). Stability of the oil was evaluated based on peroxide and TBA number, rancimat test, total carotene content, and organoleptic test. The fastest oxidation rate was show on P3 which had the highest k value of 0.20 (R2 0.99). The highest TBA value and induction time was shown on P5, respectively k value of 0.06 (R2 0.79) and 7.9 hours. Meanwhile, there was no significant change on total carotene content in mixed oil up to 14 day of storage. The result of descriptive and hedonic test showed that the ratio of patin and red palm oil had a significant effect on color, aroma, and overall assessment, but no significant effect on aroma and overall assessment after 14th day of storage. Keywords: patin oil, red palm oil, photo-oxidation, oil stability
