Fatty Acids Profile of Dried Block Tuna (Thunnus albacares) with Liquid Smoke Addition

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.

Chemical composition and fatty acid contents in farmed freshwater prawns

The objective of this work was to evaluate the chemical composition and fatty acid contents of Amazonian and giant river prawns. After four-month farming, with the same diet for both species, palmitic and stearic acids were the main saturated fatty acids. Oleic acid was the main monounsatured fatty acid, and the eicosapentaenoic and docosahexaenoic acids were the most abundant polyunsaturated acids. Amazonian prawn has higher levels of protein and polyunsaturated fatty acids than those of the giant river prawn, which shows its potential for aquaculture.
