Application of coconut shell liquid smoke on dried skipjack tuna (Katsuwonus pelamis) quality

Abstract

Liquid smoke is produced from incomplete combustion, contains various compounds with functional properties that can provide aroma, taste, and color. Liquid smoke can be used as a preservative because it contains phenols and acids as anti-bacterial and antioxidant. Application of liquid smoke as a preservative can be done in the drying process using an oven. The purpose of this study was to determine the effect of the use of liquid smoke on the quality and organoleptic of dried skipjack tuna. The use of liquid smoke in the study was 0.5%, 1% and 1.5% consisting of 3 replications. Using a completely randomized design (CRD) and the smallest real test (BNJ). Parameters observed include water content, protein content, ash content and organoleptic test consisting of 25 panellists. The results showed that the lowest water content and the highest protein were found in the A2 treatment (use of liquid smoke 1%) at 47.7% and 50.71%, respectively. The highest ash content was found in treatment A1 (0.5% liquid smoke) at 4.56%. While the highest overall organoleptic assessment of color, taste, texture and aroma were the dried Skipjack Tuna with 1,5% liquid smoke with a score of 4.4.
