Gelatin merupakan suatu protein yang diperoleh dari hidrolisis kolagen kulit dan tulang hewan. Penggunaan gelatin sangat luas dalam bidang industri pangan, non pangan dan farmasi. Umumnya gelatin diperoleh dari tulang atau kulit hewan mamalia, seperti sapi dan babi. Hal ini yang menjadikan gelatin dari tulang ikan tenggiri sebagai bahan alternatif untuk menghasilkan gelatin halal. Penelitian ini bertujuan membuat ekstrak gelatin dari tulang ikan tenggiri dengan menggunakan larutan NaOH konsentrasi 1 -5%. Parameter analisis yang diuji adalah analisis proksimat meliputi kadar air menggunakan metode thermogravimetri, kadar abu mengunakan metode drying ash, kadar nitrogen total dan kadar protein menggunakan metode Kjeldahl. Hasil penelitian diperoleh untuk kadar air sebesar 7,9568%, kadar abu 1,9444%, kadar N total 4,3356% dan kadar protein 27,097%. Dan rendemen terbanyak dari ekstrak gelatin diperoleh pada konsentrasi NaOH 5% yaitu 7,93%.Downloads
