PROFIL ASAM AMINO DENDENG GILING IKAN LELE DUMBO (Clarias gariepinus) DENGAN PENAMBAHAN KONSENTRASI ASAP CAIR YANG BERBEDA (Amino Acid Profiles of Dumbo Catfish (Clarias gariepinus) Jerked Meat Processed with Different Concentration of Liquid Smoke)

Abstract

Lele dumbo merupakan salah satu komoditas penting perikanan budidaya di Indonesia. Perkembangan pengolahan ikan sekarang lebih variatif seperti pengolahan menjadi dendeng. Penambahan asap cair pada proses pembuatan dendeng dapat meningkatkan keawetan dendeng serta memberikan karakteristik sensori. Tujuan penelitian ini adalah untuk mengetahui pengaruh penambahan konsentrasi asap cair yang berbeda terhadap kualitas dendeng. Rancangan percobaan yang digunakan adalah RAL (Rancangan Acak Lengkap). Perlakuan meliputi penambahan asap cair 0% sebagai kontrol, 1%, 3%, dan 5%. Parameter uji yang diamati adalah profil asam amino, kadar air, kadar protein, kadar fenol serta uji hedonik (kenampakan, bau, rasa, dan tekstur). Hasil penelitian menunjukkan bahwa dendeng dengan penambahan asap cair tetap memiliki asam amino yang lengkap. Lisin dan leusin dominan pada asam amino esensial dengan nilai 39702,77 - 51736,24 mg/kg, serta pada asam amino non esensial asam glutamat mendominasi dengan nilai 59915,6 - 64478,57 mg/kg. Perbedaan konsentrasi asap cair pada dendeng giling ikan lele dumbo memberikan pengaruh yang nyata terhadap penurunan kadar air, kenaikan protein dan fenol serta hedonik dendeng. Semakin besar konsentrasi yang digunakan, dendeng tidak diterima oleh panelis (p < 0,05).

Catfish is one of nutritionally important aquaculture species in Indonesia. Nowadays, the development of its processed method becomes more various such as the production of jerked meat. Addition of liquid smoke could increase shelf life of catfish and give sensory characteristics. This study aimed to determine the effect addition liquid smoke with different concentration on quality characteristics of jerked meat. The research method used Completely Randomized Design (CRD) with four treatments such as addition of 0% liquid smoke as control, 1%, 3%, and 5%. Parameters test observed are amino acid profiles, moisture content, protein content, and phenol content also hedonic test. Jerked meat processed with liquid smoke still have a complete amino acid . Lysine and leucine dominated on essential amino acid with range 39702,77 – 51736,24 mg/kg, while glutamic acid dominated on non essential amino acid with range 59915,6 – 64478,57 mg/kg. Meanwhile, addition of liquid smoke gave a significantly different to the moisture content, protein content, phenol content also appearance, odor, flavor, and texture of catfish jerked meat (p < 0,05).
