The aqueous soluble phase of acidified and autolyzed fish viscera was used as the nitrogen source in a growth medium for bacteria. The bacteria tested grew faster and produced higher yields of cell mass on this growth medium than on corresponding media with standard tryptone preparations as the nitrogen source.

Squid viscera, a byproduct of squid processing, contains oil rich in omega-3 fatty acids (up to 10% by mass) and the antioxidant astaxanthin. However, its high free fatty acid (FFA) content compromises stability. To address this, pilot-scale (200 L) enzymatic re-esterification of squid oil using immobilized lipase (Lipozyme RMIM) was demonstrated, resulting in high acylglyceride yields.

Fish visceral waste, which is normally discarded, is considered one of the richest sources of proteinases with potential biotechnological applications. For this reason, alkaline proteinases from viscera of Argentine hake Merluccius hubbsi, Brazilian flathead Percophis brasiliensis, Brazilian codling Urophycis brasiliensis, and stripped weakfish Cynoscion guatucupa were characterized. Individuals were caught by a commercial fleet off the coast of the Argentinean Sea.

Five metabolism assays were performed to determine the metabolizable energy (ME) content of soybean oil, coconut oil, fish viscera oil, physical mixture of coconut oil and fish viscera oil (3:2, in kg: kg) and structured lipid prepared from interesterification of fish viscera oil and coconut oil (3: 2, in kg: kg), and one assay to evaluate the effects of including these lipid sources in piglet diets on performance, digestibility of diets, incidence of diarrhea and intestinal morphometry at nursery phase. Soybean, coconut, fish viscera, physical mixture and structured lipid oils showed ME values of 8239, 8199, 8839, 8268 and 8523 kcal/kg DM respectively. In the performance trial, a total of 90 piglets with 23 days of age were distributed among 5 diets, differing in the lipid source used (soybean oil, coconut oil, fish viscera oil, physical mixture or structured lipid).

To investigate the impacts of glycation modification on the structure and flavor of fish viscera-derived protein hydrolysates, channel catfish viscera was utilized and hydrolyzed by Flavourzyme, followed by glycation with glucosamine, xylose, ribose and glucose, respectively. The structural characteristics, taste and odor of glycated products were evaluated. The results revealed that glycation led to an increase in peptides (<1 kDa) and a decrease in peptide fraction (>5 kDa).
