Abstract
Dry fish block is a food product from by-product of tuna loin. It is salted, liquid smoked, and dried.This study was aimed to determine fatty acid profile of the dry fish block after the addition of liquid smoke.The dry fish block was composed of twelve saturated fatty acids (SFA), six monounsaturated fatty acids(MUFA), and nine polyunsaturated acids (PUFA). The total of SFA in dry fish block without and with liquidsmoke was 19.94% and 21.29%, while MUFA was 9.35% and 11.77% and PUFA was 14.45% and 16.04%,respectively.

Summary
Bahan baku utama dari penelitian ini adalah tetelan tuna beku yang diperoleh dari PT Harta Samudera Ambon, Maluku, garam (merk dolfin) 4% dan asap cair 2% (dari berat tetelan ikan tuna). Asap cair yang digunakan diproduksi oleh Program Studi Teknologi Hasil Perikanan Fakultas Perikanan dan Ilmu Kelautan, Universitas Pattimura Ambon). Bahan kimia untuk analisis asam lemak adalah NaOH, BF3, NaCl, heksana, dan Na2SO4. Peralatan utama yang digunakan adalah alat pengering kabinet (buatan Balai Pelatihan dan Penyuluhan Perikanan Ambon), GC (Shimadzu GC 17+, Japan), timbangan digital (Shimadzu, AUY, Indonesia) meat grinder (OX-861 N, Oxone-Indonesia), HI-power mixer (Megafesa, Korea)
