Abstract:
Recently, there has been a major concern about fisheries waste produced by tuna processing factories. There are many ways to handle the waste from tuna processing factories, specifically the tuna viscera which contains the stomach, pyloric caeca, kidneys, and intestines. The tuna viscera have been known as a source of digestive enzymes, one of them is a protease, including trypsin. The objective of this research was to analyze the enzymatic characteristic of trypsin extracted from two different tuna species. In this study, the trypsin extracted from the intestines of yellowfin and bigeye tuna

Abstract:
The viscera of skipjack tuna (Katsuwonus pelamis) is often regarded as an underutilised waste in the fishing industry, with approximately 20% of the total weight of skipjack waste being discarded, which presents a cost burden for producers. Although skipjack tuna has been studied previously, the nutritional potential of its viscera as a food source still requires further exploration. Therefore, this study aims to evaluate the nutritional content of skipjack tuna viscera obtained from the fish processing industry. Analysis was conducted on the proximate composition, including moisture, protein,

Abstract:
Tuna viscera as a common waste product from the tuna processing industry contributes to environmental pollution. The effects were determined of peptide fractions and amino acids on the antioxidant properties of protein hydrolysate from tuna viscera. We converted this waste into protein hydrolysate, a high added-value product, using autolysis. Tuna protein hydrolysate was fractionated by ultrafiltration into four fractions (>10 kDa, 5–10 kDa, 1–5 kDa and <1 kDa) and each was examined for its antioxidant properties (DPPH, ABTS, FRAP and metal chelating) and amino acids composition.

This study aims to analyze the nutritional composition of the degree of hydrolysis and amino acids in the internal organ waste of tuna and the protein hydrolyzate of tuna's internal organs after fermentation using the Bacillus licheniformis bacteria. The analysis showed that the protein content of tuna offal was 53.52%, and after fermentation by Bacillus licheniformis, bacteria were able to increase protein levels from 56.04. The degree of hydrolysis of protein (DH) showed an increase of 13.24% in tuna offal to 22.28% of protein hydrolyzates are fermented tuna innards. The total essential amin

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.

Abstract:
Proteinaceous wastes from the fishery process are an abundant renewable resource for the recovery of a variety of high-value products. This work attempted to utilize several proteinaceous wastes to produce proteases using the Streptomyces speibonae TKU048 strain. Among different possible carbon and nitrogen sources, the protease productive activity of S. speibonae TKU048 was optimal on 1% tuna head powder. Further, the casein/gelatin/tuna head powder zymography of the crude enzyme revealed the presence of three/nine/six proteases, respectively. The crude-enzyme cocktail of S. speibonae TKU048

Abstract:
Southern bluefin tuna (Thunnus maccoyii) warm their viscera when digesting food. Through surgical implantation of archival tags, this thesis explores visceral warming patterns in southern bluefin tuna (SBT) with the aim of identifying relationships between visceral heat, nutrient supply, feed frequency and efficiency in SBT. Based on six trials with different but related objectives, it was found that dietary energy influences visceral warming, time taken to reach peak visceral temperature and duration of visceral warming when SBT receive one meal per day. When SBT are fed more than one meal p
