Abstract

Kurisi fish oil is a promising omega–3 fatty acid source, particularly eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). In Indonesia, this oil is commonly obtained from a surimi processing industry product. It is predominantly utilized as an additive in animal feed due to its failure to meet the quality standards required for human consumption. Therefore, purification is essential to enhance its quality and broaden its potential applications as a food–grade oil. This study evaluated the effectiveness of two purification methods: (A) a three–step process involving degumming, neutralization, and bleaching; and (A+), which includes winterization following the A process. The study commenced with the characterization of crude kurisi fish oil, followed by applying both purification techniques. Quality parameters analyzed included free fatty acids (FFA), peroxide value (PV), acid value (AV), p–anisidine value (p–AnV), total oxidation value (totox), and fatty acid composition. The results indicated that both purification methods significantly reduced oxidative degradation indicators. Notably, the A+ method yielded the most favorable results, achieving a polyunsaturated fatty acid (PUFA) content of 33.69% and demonstrating superior oxidative stability. These findings suggest that the A+ purification method effectively enhances the quality of kurisi fish oil, supporting its potential use as a functional food ingredient.

Abstract

A training program on the application of chitosan as a natural coating agent for smoked fish products was conducted for the Smoked Fish Processing Group at the Mushola Bukit Salam Rest Area, Prigi Village, Trenggalek Regency. The objective of this training was to enhance participants' knowledge and skills in utilizing chitosan as a natural preservative to extend shelf life and improve the quality of smoked fish. The training activities included interactive lectures, practical demonstrations on the preparation of chitosan solution, and evaluations comparing the shelf life of treated and untreated smoked fish products. Observational results indicated that smoked fish coated with chitosan exhibited a longer shelf life and greater resistance to fungal growth and insect contamination compared to uncoated samples. Additionally, questionnaire-based evaluations revealed a significant increase in participants’ understanding of the benefits and applications of chitosan. The training received highly positive feedback, with participants expressing interest in the continuation of similar programs. These findings suggest that chitosan training positively contributes to the capacity of local fish processors to produce safer, more hygienic, and market-competitive smoked fish products.
