The processing of fish results in the production of by-products that have potential use in a variety of areas, including the food industry. The purpose of this study is to examine the effects of thermal treatment and cold pressing on the nutritional and functional aspects of the byproducts that are created from the hydrolyzed of fish scraps, with the ultimate goal of maximising the value of these byproducts. According to the results of the studies, fish trimmings are valuable sources of protein, which may be dissolved in pepsin at a rate ranging from 78 to 79 percent after being hydrolyzed. The finished products exhibit functional qualities such as high emulsification activities (ranging from 45 to 49%) and a high degree of stability (ranging from 83% to 76%), regardless of the kind of drying process used. When compared to drying in an oven, the functional qualities that are produced by freeze-drying are somewhat superior.
Fish trimmings could have a high protein content. As expected, pepsin hydrolysis is very effective in emulsification these native molecules. Proteins preserved by drying at 70°C and by dehydrating both show fascinating functional features, although those preserved by freeze-drying have a slight edge. Dehydration at 70 degrees Celsius or freezing is possible for enzymes. Additional study of protein sequence and morphogenesis during evaporation may help corroborate these findings. More research into the most efficient use of this method is required if oven drying is to become more economically viable. Whatever the case may be, using fish scraps as a raw material for commercial products is an intriguing and possibly productive way for the food industry to create new kinds of bioactive components.
