ABSTRACT Incorporation of omega-3 polyunsaturated acids (n-3 PUFA) into Tuna (Thunnus thynnus) fish oil was investigated by using acidolysis enzimatis Process. The product of this modification is expected to be used as an ingredient nutrifition food products, especially in milk and baby food as well as pregnant and lactating The purpose of this study was to optimizing the used of lipased papaya latex (Carica papaya latex) in the product to incorporation fatty acids rich in omega-3.Bioreactor acidolysis enzematik development and Optimization of process the productivity of fatty acids rich in omega-3. Reaction Acidolysis was conducted between tuna (thunnus thynnus) fish oil by microbial lipase (5% of the weight of the substrate mixture) or vegetable lipased (Carica papaya latex) (6-10% by weight subtract mixture) as biocatalist.Acidolysis mixture the bioreactor at 40 o C for (2-6 hours) and the stirring speed of 200 rpm, pH (4.5 to 6.5). to eliminate free fatty acids from the product acidolysis performed neutralization with NaOH The results are expected to show that the lipase papaya latex (Carica papaya latex) can be used as biocatalyst incorporated omega-3 fatty acids in   tunaIthunnus thunnyl) fish oil . In this study sought conditions for optimum incorporation rate, ie the use of papaya latex lipase concentration of 8%, the ratio of concentrations of omega-3 fatty acid and palm oil (1:1), pH = 5.5, Optimal time of 4 hours and the temperature (40oC) .

Abstract   Red palm oil is source of p carotene and vitamin E, while Tuna fish is source of omega-3 and 6. Diversification of palm oil and tuna fish oil can be used as food supplement. The utilization of high concentration of minor vitamin is one of strategy to increase the additional value of both oil and also to provide minor vitamin from local product in order to increase the healthy of the society. There was some research conducted on micro encapsulation process of red palm oil which is rich of P carotene, provitamin A, and provitamin E. And there was also research subjected to microencapsulated fish oil which is rich of omega-3. In this research we combined the microencapsutaion of both red palm oil and tuna fish oil through enzymatic cytolysis process. From the cytolysis process, we will got type of fatty acid which is rich of omega 3 and P carotene . The objective of the research were to study the activity of rice bran lipase as biocatalisator in the conversion of palm oil fatty acid into fatty acid which is rich of omega-3, and to develop the bioreactor for the enzymatic cytolysis for fatty acid production. The research result showed that optimum condition for the cytolysis process was the ratio of red palm oil tuna fish oil 3:1, temperature 40oC; reaction time 4 hours, where the yield of fatty acid has EPA and DHA concentration 35,92% and 5,65%, respectively. While the rate of the reaction was 619,67 mol/hour. Red palm oil is an alternative source of fatty acid which is rich of omega 3 (EPA and DHA), and it can be produced by enzymatic cytolysis by using rice bran lipase. Lipase enzyme of R Meithei found to be a good biocatalyst in the red palm oil and tuna fish incorporation process of the fatty acid which is rich of omega-3.   Key words: citolysis, red palm oil, tuna fish oil
