STUDI PROSES PENGOLAHAN PRECOOKED TUNA LOIN FROZEN JENIS SKIPJACK TUNA

Abstract

Skipjack Tuna (Katsuwonis pelamis) is included in the large pelagic fish group as one of the marine fishery commodities with important economic value. Therefore, proper and efficient processing is needed which aims to maintain the quality of the fish and obtain optimal results. One of the processing skipjack tunas is precooked tuna loin frozen. The aim of this research was to analyze the process of precooked frozen tuna loin and analyze the production of precooked frozen tuna loin based on mass balance calculations. The work method was carried out by directly following the processing stages of frozen precooked tuna loin and recording the rendement yields in each process. Results of the research were that the processing of precooked tuna frozen loin consisted of three main stages. The first stage is preparation which includes the process of receiving, size grading, thawing, washing 1, butchering, washing 2, racking, and cooking. The second stage is production which includes the process of cooling, misting, deskin/skin off, cleaning, sorting, packing, and ABF freezing. The third stage is finish which includes the process of sacking, cold storage, and stuffing. The processing of precooked frozen tuna loin produced final products of 8.08 kg (45.39%), 6.93 kg (38.93%) in loin forms and 1.15 kg (6.46%) in shredded form.
