Abstract

Kulit ikan salmon merupakan salah satu hasil samping yang dapat diolah menjadi kolagen. Kolagen larut papain (PaSC) adalah istilah yang digunakan untuk menggambarkan kolagen yang diekstraksi menggunakan kombinasi asam dan enzim papain. PaSC berpotensi menjadi sumber kolagen halal. Penelitian ini bertujuan untuk menentukan waktu ekstraksi dan konsentrasi enzim papain terbaik dalam menghasilkan kolagen kulit ikan salmon berdasarkan persentase rendemen dan sifat kimia. Kulit ikan salmon diekstrak menggunakan kombinasi asam asetat (0,5 M) dan enzim papain (500; 1.000; 1.500 U/mg/g kulit) selama 1; 2; dan 3 jam. Parameter yang dianalisis dalam penelitian ini meliputi logam berat, rendemen, asam amino, gugus fungsional, dan berat molekul. Hasil penelitian menunjukkan bahwa perlakuan kombinasi asam asetat konsentrasi 0,5 M dan enzim papain 1.000 U/mg/g selama 2 jam menghasilkan kelarutan kolagen yang maksimal dengan rendemen sebesar 15,38% (bk). Kolagen PaSC kulit ikan salmon terdeteksi memiliki asam amino prolina, glisina, dan arginin. Distribusi berat molekul kolagen berada pada rentang 20-142 kDa. Struktur triple helix kolagen tidak mengalami perubahan selama proses ekstraksi berdasarkan analisis FTIR.
