Abstract

“Minyak Ala Muncar” or abbreviated as MAM is a by-product waste of fish canning factory in Muncar Banyuwangi Indonesia. MAM was widely distributed throughout Indonesia to be used as animal feed supplements. MAM was very potential to be converted into oil rich in n-3 through the recycling process. The recycling process needs to be conducted because MAM contained trans-FA especially EA which could have a detrimental impact on health. Therefore, the aim of this research was to produce an oil fraction that rich in n-3 and low in trans-FA content. Three crystallization methods namely crystallization with n-hexane solvent, acetone solvent, and urea were chosen as the recycling method. The MAM Recycling research was carried out through several stages, namely oil hydrolysis, winterization with solvents (acetone, n-hexane), urea crystallization, fractions esterification, Fatty Acid content analysis. The results showed that both crystallization with n-hexane and acetone produced ratio value of PUFA/trans-FA, n-3/trans-FA, EPA/EA, and DHA/EA below 0.3 respectively. While urea crystallization was able to produce ratio numbers for each PUFA/trans-FA, n-3/trans-FA, EPA/EA, and DHA/EA PUFA/trans-FA 1.46±0.05, 1.36±0.04, 0.73±0.021, 0.48±0.035.
