KARAKTERISTIK KIMIA DAN MIKROBIOLOGI BAKASANG JEROAN IKAN TUNA SIRIP KUNING (Thunnus Albacares)
Abstract
Tuna is a raw material with low quality if not utilized it can cause environmental problems, therefore processing is necessary to increase added value. Tuna fish innards are processed traditionally by fermenting them into bakasang. This study aims to determine the chemical and microbiological quality of the viscera of yellowfin tuna (Thunnus Albacares). The method used is an experimental method with the treatment carried out is a salt concentration of 10%, 20%, 30%, and the duration of fermentation is 2 weeks, 4 weeks, 6 weeks. Objective tests carried out in the study included water content, protein content, pH value and total LAB. The results showed that the length of fermentation and the concentration of salt in yellowfin tuna meatballs had a significant effect on decreasing water content, protein content, pH value and increasing the total value of lactic acid bacteria. A good yellowfin tuna is a fermentation/storage period of 4 weeks and 6 weeks with a salt concentration of 20% and 30%, respectively.
