Sensory, Chemical and Microbiological Properties of Trout Sausage (Fermented Sucuk)

Abstract

This study aimed to produce fish sucuk using rainbow trout (Oncorhynchus mykiss) fillet and inves-tigate its suitability for consumption. Sensory, nutrient composition, fatty acid and amino acid com-position analyses were carried out in the sucuk prepared with a commercial spice mix. Total aerobic mesophilic bacteria, total coliform, total Enterobacteriaceae, Lactic acid bacteria, yeast and mould counts were found to be smaller than 1 log cfu g-1. It was found that the ratio of water, protein, fat, ash,totalsaturatedFA,totalmono-unsaturatedFAandtotalpoly-unsaturatedFAwere48.63%,17.27%, 22.00%, 2.52%, 50.17%, 43.23% and 6.6%, respectively. Glutamic acid (19.1 g 100 g-1), aspar-tic acid (17.17 g 100g-1), leucine (9.45 g 100 g-1) and lysine (8.05 g 100 g-1) were the main amino acids in fish sucuk. In addition, the sensory analysis results of the sucuk produced entirely from trout meat showed that it was acceptable. This study concluded that a sucuk product suitable for con-sumptioncouldbeproducedusingtroutmeatentirely,withtheappropriatespicemixture,heattreatment and air conditions.
