Abstract

The nutritional content of catfish allows this freshwater fish to be processed into a variety of products, one of which is fish floss. Fish floss is a product that is popular among the people so that many use it for sale and increase income. However, unfortunately many fish floss products that are of poor quality, for example, oil appeared in the packaging which consequently makes the fish floss products quickly rancid. The purpose of this study was to determine the optimal shelf life of floss catfish with the best quality. The experimental laboratories of this study was divided into three treatments: spinnered, pressed and combination of spinnered and pressed. The quality of fish floss were observed every 12 days for 48 days.The results showed that there were significantly effect of floss catfish with different treatments of oil reduction. The best quality of floss catfish was achieved at 36 days storaging, with an average value of water content 4.99%, 28.39% of protein content, 9.15% of fat content, 4.99 meq kg-1 of peroxide value and total plate count 6.9 x 10-3 cfu g-1.

Abstract

Karagenan merupakan hidrokoloid yang diperoleh dari hasil ekstrak rumput laut merah (Rhodophyta). Alginat merupakan salah satu jenis hidrokoloid, yaitu suatu sistem koloid oleh polimer organik di dalam air. Keduanya mempunyai fungsi sebagai pembentuk gel. Tujuan dilakukannya penelitian ini adalah untuk mengetahui pengaruh kappa karagenan, iota karagenan dan alginat terhadap kualitas pasta ikan (bakso) selama penyimpanan suhu dingin. Penggunaan karagenan dan alginat sebanyak 3% dari berat daging ikan, pengujian pasta ikan dilakukan setiap  1 minggu sekali selama 21 hari meliputi uji gel strength, kadar air, kadar Aw. Hasil penelitian menunjukkan  bahwa pasta ikan (bakso) dengan penambahan kappa karagenan mendapatkan nilai kekuatan gel terbaik yaitu: 1884,500±0,36 g.cm, lalu iota karagenan yaitu: 1313,567±0,90 g.cm, alginat: 1278,010±0,61 g.cm dan kontrol: 1149,397±0,94 g.cm. Selama 21 hari proses penyimpanan suhu dingin (4oC) didapatkan nilai gel strength terbaik dengan penambahan kappa karagenan yaitu 2727,460±0,56 g.cm. Penambahan kappa karagenan memberikan pengaruh paling tinggi terhadap kekuatan gel selama penyimpanan suhu dingin dibandingkan iota karagenan dan alginat.
