Pengaruh Ekstrak Daun Belimbing Wuluh (Averrhoa blimbi L) Terhadap Ketahanan Mutu Ikan Patin (Pangasius sp) Segar
This study aimed to determine the effect of belimbing wuluh (Averrhoa bilimbi L.) leaf
extract on the shelf-life quality of fresh Pangasius sp. fish and to determine the optimal concentration of the extract. The study used a completely randomized design (CRD) with non-factorial treatment, consisting of four levels of extract: (P0) no extract, (P10) 10% extract, (P15) 15% extract, and (P20) 20% extract. The treatments were further grouped based on the storage duration, which included 4, 8, and 12 hours. The results of this study showed that the belimbing wuluh leaf extract affected the sensory characteristics of Pangasius sp. fish. For appearance, aroma, taste, and texture, the hedonic organoleptic scores for treatments P0–P20 ranged from 6.99 to 7.25, while quality organoleptic scores ranged from 6.56 to 7.94 (appearance, aroma, taste, and texture). The fish displayed visual characteristics including flattened eyeballs, a cloudy cornea, a grayish pupil, and gills that were dark red or light brown with cloudy mucus. The fish's body surface was covered with cloudy mucus. Regarding the fish's flesh, the cuts appeared less glossy, the flesh tissue was firm, and the odor remained fresh with a less-specific fishy smell. The taste of the fish was fresh, slightly sweet, and mildly sour, while the texture was soft and elastic. As for the chemical and microbiological characteristics, the fish had a pH value of 6.61, a TVB level of 11.32 mgN/(100 g), and an TPC of 1.44 × 10⁴ cfu/g.
