Abstract
Abstrak
Objectif. Salami adalah salah satu produk asal daging yang dibuat dengan penambahan kultur bakteri yang kemudian difermentasi selama ±48 jam. Penelitian ini bertujuan untuk mengetahui kosentrasi penggunaan tepung umbi uwi (Dioscorea spp.) sebagai prebiotik terhadap kualitas kimia dan kualitas mikrobiologi yang meliputi uji kadar pati, uji pH, uji TAT, dan uji BAL salami daging ayam broiler.
Materi dan Metode. Bahan yang digunakan dalam penelitian ini adalah ayam broiler yang ditambahkan tepung uwi dengan kosentrasi yang berbeda. Penelitian ini menggunakan rancangan acak lengkap (RAL) dengan pola searah yang terdiri dari 4 perlakuan yaitu dengan konsentasi 0%, 5%, 15%, dan 25%, masing-masing perlakuan terdiri dari 3 ulangan sehingga diperoleh 12 kali ulangan atau 12 unit percobaan.
Hasil. Hasil penelitian menunjukkan konsentrasi 5% (P1) sampai 25% (P3) mampu meningkatkan viabilitas bakteri asam laktat sebesar 6,58% sampai 6,94% log CFU/g serta dapat meningkatkan nilai TAT. Penambahan tepung umbi uwi dengan konsentrasi 5% (P1) sampai 25% (P3) juga dapat menurunkan kadar pati dan pH dari salami.
Kesimpulan. Kesimpulannya penambahan tepung uwi dengan kosentrasi yang berbeda mampu mempengaruhi kualitas salami daging ayam broiler.
Conclusion. The conclusion is the addition of uwi flour with different concentrations can affect the quality of broiler chicken salami.
Abstrack
Objectif. Salami is one of the meat products made with the addition of bacterial culture, fermenting for ± 48 hours. This study aims to determine the concentration of the use of Uwi tuber flour (Dioscorea spp.) As a prebiotic on chemical quality and microbiological quality, which includes starch test, pH test, TAT test, and BAL test for broiler chicken salami.
Material and Methods. The material used in this research is broiler chicken, which added with uwi flour with different concentrations. This study uses a completely randomized design (CRD) with a unidirectional pattern consisting of 4 treatments, with a concentration of 0%, 5%, 15%, and 25%. Each treatment consists of 3 replications so that 12 replicas or 12 units of trials obtained.
Results. The results showed a concentration of 5% (P1) to 25% (P3) could increase the viability of lactic acid bacteria by 6.58% to 6.94% log CFU / g and could increase the TAT value. The addition of Uwi bulbs with a 5% (P1) to 25% (P3) can also reduce starch levels and pH from salami.
Conclusion. The conclusion is the addition of uwi flour with different concentrations can affect the quality of broiler chicken salami.
