“…Intracellular lipid is strongly bound to the protein matrix (Rubio-Rodríguez et al 2012 ), which requires its removal from FBPs in order to achieve higher efficiency of enzyme isolation (Asaduzzaman and Chun 2015 ). For example, Geethanjali and Subash ( 2013b ) claimed that 45% of fat in the viscera of Indian major carp ( Labeo rohita ) (Pathak et al 1954 ) makes the homogenization of the sample difficult. Furthermore, the resulting extract contains a high quantity of finely dispersed lipid which complicates the subsequent purification steps of enzymes.…”

Supercritical carbon dioxide (Sc-CO2) is an alternative tool to extract lipid for the production of fish oil and enzyme from fish by-products (FBPs). In the application of Sc-CO2, this review covers sample preparation, lipid extraction operation, and characterization of fish oil and enzyme as final products. Generally, the fish samples with moisture content less than 20% and particle size less than 5 mm are considered before lipid extraction with Sc-CO2. Sc-CO2 parameters, such as pressure (P), temperature (T), extraction time (text), and flow rate (F), for simultaneous recovery of fish oil, protein, and enzyme were found to be less severe (P: 10.3–25 MPa; T: 25–45 °C, text: 20–150 min; F: 3–50 g/min) than the extraction of fish oil alone (P: 10–40 Mpa; T: 35–80 °C; text: 30–360 min; F: 1–3000 g/min). The enzyme from the Sc-CO2 defatted sample showed higher activity up to 45 U/mg due to lower denaturation of protein as compared to the organic solvent treated sample albeit both samples having similar pH (6–10) and temperature stability (20–60 °C). Overall, mild extraction of lipid from FBPs using Sc-CO2 is effective for the production of enzymes suitable in various industrial applications. Also, fish oil as a result of extraction can be produced as a health product with high polyunsaturated fatty acids (PUFAs) and low contamination of heavy metals.

The fatty-acid composition of the body and visceral fats of Stromateus cinereus (an Indian ' boundary ' fish) was studied by lithium salt-acetone, lead salt-alcohol fractionations and further by methyl ester distillation. The fats are of intermediate type and form a distinct class from fresh water and marine fish fats although the degree of unsaturation is of the same order in all three types of fats. As compared with British ' boundary ' fish fats, these fats are more saturated. IntroductionThe component acids of fats from different parts of the several Indian fresh water fish and of a few fats from Indian marine animals were studied by Pathak and co-workers.l.
