Penelitian ini bertujuan untuk mengetahui efek lama stimulasi dan tegangan listrik terhadap komposisi kimia, kualitas fisik, dan sensori daging ayam petelur afkir. Penelitian ini menggunakan Rancangan Acak Lengkap pola faktorial 3 x 4 dengan 6 kali ulangan pada setiap kombinasi. Sampel penelitian adalah 72 ekor ayam petelur afkir yang dibagi menjadi 3 kelompok perlakuan dengan lama stimulasi 0, 1, dan 2 menit, dan 4 kelompok perlakuan stimulasi listrik 60, 75, dan 90 volt, dan kontrol dengan jumlah ulangan masing-masing 6 kali. Interaksi lama stimulasi dan tegangan listrik berpengaruh nyata terhadap kualitas fisik daging, yaitu pH, daya ikat air, susut masak, keempukan, dan kadar protein daging. Stimulasi listrik selama dua menit dengan tegangan 90 volt dapat memperbaiki kualitas fisik daging ayam petelur afkir, dibandingkan dengan kombinasi lainnya. Interaksi antara lama stimulasi dan tegangan listrik dapat memperbaiki kualitas sensori daging yaitu keempukan, warna, aroma, dan tekstur daging ayam petelur afkir.
<p>The aim of this research was to study the effect of different length of conditioning time and types of cooking on sensory quality of meat from goats under traditional way of keeping in remote villages. The result of this research would lead to the ability to decide the better conditioning processes post slaughtering to increase meat quality. The research was done following a completely randomized design of 4x2 factorial, each combination of experimental treatment had three replications. The first factor was the length of conditioning (A), which were consisted of without conditioning (A0), three hour conditioning (A1), six hour conditioning (A2), and nine hour conditioning (A3). The second factor was the types of cooking (B) which were cooking by boiling (A1), and cooking by roasting (A2). The<br />result from a panel test indicated that conditioning processes for nine hours had capable of increasing quality of local native goat meat especially on aroma, flavor, juiciness, and final pH, mean while in the case of tenderness it did not<br />show any affect of different length of conditioning and types of cooking. Better quality would be obtained when conditioning was done for nine hours in side refrigerator.</p><p>(Key words: Goat meat conditioning, Type cooking, Sensory quality)<br /><br /></p>
Penelitian bertujuan untuk memanfaatkan hasil sampingan karkas sapi dan meningkatkan nilai guna serta mengevaluasi tingkat kesukaan konsumen melalui uji nilai kesukaan dan uji fisik. Penelitian ini dilaksanakan di Laboratorium Jurusan Peternakan Fakultas Peternakan Universitas Haluoleo, Kendari pada bulan Februari sampai bulan Maret 2012. Penelitian menggunakan Rancangan Acak Lengkap, 4 perlakuan dan 3 ulangan. Perlakuan terdiri atas N1= daging ayam ras petelur afkir 100% dan otak sapi 0%, N2= daging ayam ras petelur afkir 90% dan otak sapi 10%, N3= daging ayam ras petelur afkir 80% dan otak sapi 20%, dan N4= daging ayam ras petelur afkir 70% dan otak sapi 30%. Variabel penelitian meliputi uji fisik (pH dan susut masak) dan uji sensorik (warna, aroma, tekstur, rasa, keempukan dan penampakan umum). Hasil penelitian menunjukan pengaruh yang nyata (p<0,05) terhadap nilai pH dan susut masak nugget dimana subtitusi otak sapi pada nugget daging ayam petelur afkir hingga 30% meningkatkan nilai pH dan menurunkan susut masak serta tidak memberikan pengaruh yang nyata (p>0,05) terhadap nilai kesukaan nugget. Otak sapi dapat digunakan hingga 30% dalam pembuatan nugget daging ayam petelur afkir. Kata kunci: Nugget, Kualitas fisik, Tingkat kesukaan, Daging ayam dan Otak sapi
