“…Although neutrase generates the least amounts of TAAs, the ratio of EAAs to TAAs was the highest in the yeast protein, reaching 71.80%. According to the ideal model proposed by the Food and Agriculture Organization and the World Health Organization, the reference value for high-quality protein should be over 40% ( Li et al, 2022 ). Therefore, proteins treated with neutrase, flavourzyme, and prozyme 2000P were confirmed to be of high quality compared with the control group.…”

Yeast protein can be a nutritionally suitable auxiliary protein source in livestock food. The breakdown of proteins and thereby generating high-quality peptide, typically provides nutritional benefits. Enzyme hydrolysis has been effectively uesed to generate peptides; however, studies on the potential applications of different types of enzymes to produce yeast protein hydrolysates remain limited. This study investigated the effects of endo- (alcalase and neutrase) and exotype (flavourzyme and prozyme 2000P) enzyme treatments on yeast protein. Endotype enzymes facilitate a higher hydrolysis efficiency in yeast proteins than exotype enzymes. The highest degree of hydrolysis was observed for the protein treated with neutrase, which was followed by alcalase, prozyme 2000P, and flavourzyme. Furthermore, endotype enzyme treated proteins exhibited higher solubility than their exotype counterparts. Notably, the more uniform particle size distribution was observed in endotype treated yeast protein. Moreover, compared with the original yeast protein, the enzymatic protein hydrolysates possessed a higher content of β-sheets structures, indicating their higher structural stability. Regardless of enzyme type, enzyme treated protein possessed a higher total free amino acid content including essential amino acids. Therefore, this study provides significant insights into the production of protein hydrolysates as an alternative protein material.

Clarias gariepinus and Oreochromis niloticus are two important fish species that are widely consumed in many parts of the world. This study investigated the nutritional composition, fatty acid profiles and organoleptic evaluation of these two fish species raised under wild and pond-cultured systems. Five samples each of the species were randomly collected from Ashaka Town, Delta State, Nigeria. The proximate composition was determined using standard AOAC methods. Fatty acid profiles were analyzed using gas chromatography, while organoleptic evaluation was conducted using twenty panelists. C. gariepinus exhibited significantly lower (p<0.05) moisture content (77.76±0.45 and 79.06±0.36) and higher crude fat content (1.75±0.14 and 1.32±0.33) respectively in both wild and pond-cultured species compared to O. niloticus. C. gariepinus had higher protein content than O. niloticus in both wild and pond-cultured species. The carbohydrate content of O. niloticus was significantly higher (p<0.05) than in C. gariepinus, while the ash content of C. gariepinus and O. niloticus was not significantly different (p>0.05). Both species exhibited variations in their fatty acid profiles, with significant differences (p<0.05) observed in the levels of saturated fatty acids (SFAs), monounsaturated fatty acids (MUFAs) and polyunsaturated fatty acids (PUFAs). All wild and pond- cultured fish species had the same pattern of fatty acid composition SFAs > PUFAs > MUFAs except wild C. gariepinus with SFAs > MUFAs > PUFAs pattern. Pond-cultured O. niloticus and C. gariepinus had higher total n-3 PUFAs and lower n-6 PUFAs values while wild O. niloticus and C. gariepinus had lower n-3 PUFAs and higher n-6 PUFAs values. This difference was statistically significant (p<0.05). The results indicated significant organoleptic differences (p<0.05) in consumer preference between wild and pond-cultured C. gariepinus, however, O. niloticus was found to be liked similarly regardless of its source (p>0.05). These findings suggest that the type of habitat, fish species and diets have significant impacts on the proximate composition, fatty acid profiles and organoleptic attributes of fishes.
