摘要：Potency of culled Saanen crossbred goat meat to replace the supply of yearling Boer crossbred goat meat was evaluated. Selected muscles from leg and shoulder cuts were analysed for their nutritional (proximate composition, collagen, amino acids, fatty acids), physicochemical (pH, myoglobin, drip loss, cook loss, shear force, lightness (L*) redness (a*) yellowness (b*), microstructure), and sensory (triangle test, hedonic test) evaluations. Meat samples from culled Saanen crossbred goat exhibited higher values in protein, collagen, and MUFA (P<0.05) than those from Boer crossbred goat, while lower values in ash, soluble collagen, and SFA were obtained (P<0.05). Meat from culled Saanen crossbred goat revealed higher cook loss, shear force, and redness compared to those from a yearling Boer crossbred goat (P<0.05). In addition, thicker perimysium in meat of Saanen crossbred goat was obtained particularly that could be seen on leg part. In sensory evaluation result, the panels could detect the differences between raw meat characteristics of these goat breeds (P<0.05) within the same muscle. However, the panels could not distinguish the difference between breeds in leg meat after being cooked. Shoulder meat of Saanen crossbred goat had less acceptance level compared to the other samples (P<0.05) particularly on its texture and taste quality. In summary, shoulder cut of culled Saanen crossbred goat exhibited a well-intentioned potency to substitute the supply of meat from yearling Boer crossbred goat. Nevertheless, pre-treatment might be applied to leg cut of Saanen crossbred goat to solve the less acceptance level of its textural and taste characteristics.
其他摘要：Potensi daging kambing peranakan Saanen tua untuk mensubstitusi suplai daging kambing peranakan Boer telah dievaluasi. Otot dari bagian kaki dan bahu telah dianalisis untuk melihat kandungan nutrisi (komposisi proksimat, kolagen, asam amino, dan asam lemak), sifat fisikokimia (pH, mioglobin, susut drip, susut masak, shear force, lightness (L*) redness (a*) yellowness (b*), dan mikrostruktur), dan penilaian sensori (uji segitiga dan uji hedonik). Berdasarkan penelitian didapatkan bahwa kandungan protein, kolagen, dan MUFA daging kambing peranakan Saanen lebih tinggi (P<0.05) daripada daging kambing peranakan Boer, sedangkan kadar abu, kolagen terlarut, dan SFA-nya lebih rendah (P<0.05). Susut masak, shear force, dan redness daging kambing peranakan Saanen lebih tinggi daripada daging kambing peranakan Boer (P<0.05). Selain itu, gambaran perimisium yang lebih tebal (P<0.05) pada daging kambing peranakan Saanen telah didapatkan, terutama dapat dilihat pada bagian kaki. Pada penilaian sensori, panelis dapat membedakan daging mentah dari kedua bangsa kambing pada dua bagian karkas, tetapi panelis tidak dapat membedakan daging kaki di antara kedua bangsa kambing setelah dimasak. Daya terima panelis terhadap daging bahu paling rendah (P<0.05) dibandingkan sampel lainnya, terutama terkait dengan kualitas tekstur dan rasanya. Dapat disimpulkan bahwa daging bagian bahu kambing peranakan Saanen berpotensi sebagai alternatif pengganti daging kambing peranakan Boer. Sementara itu, daging bagian kaki kambing peranakan Saanen memerlukan perlakuan lanjutan untuk mengatasi daya terimanya yang rendah terkait sifat tekstur dan rasanya.
