Abstract
Riau Province is the region that has the largest plantation area in Indonesia with 2.4 million hectares of land in 2017 and production contributes 6 million tons per year and contributes 28.2 percent of Indonesia’s total CPO exports. On the other hand, the Kampar and Pelalawan districts are centers for the production of special freshwater fish for catfish (Pangasius hypoptalmus), where from year to year they have increased rapidly. This study aimed to charaterized oil mixed of red palm oil and catfish oil byproduct of catfish fillet. This research was conducted using a one-factor factorial experimental method, namely the difference in the ratio of the mixture between red palm oil and catfish oil. Red palm oil and catfish are stirred in a ratio of 70: 30 (B1), 60: 40 (B2), and 50:50 (B3). A serial of organoleptic and chemical test (saponification rate, iodine number, number acid, and fatty acid profile) were carried out. The results showed saponification rate was - 295.36, iodine concentration was 80.33 and acid number was 0.05. Furthermore, the fat content of each ratio B1 (14.28%, B2 (16.21% and B3 (17.11%), while the types of fatty acids obtained are saturated fatty acids (SAFA), unsaturated fatty acids single (MUFA) and polyunsaturated fatty acids (PUFA). The quality of the mixture of red oil and catfish oil produced in this study meets the FDA (Food and Drug Administration) standards, in which the best one was B3 (50: 50). It can be interpreted that the mixture can be used as a source of fatty acids needed by the body which contains omega-9 fatty acids, omega-6 and omega-3.
