Title : Total phenolic and flavonoid content, antioxidant properties of Oulmes bovine milk in Morocco in different seasons

Abstract :

Milk is a comprehensive diet that comprises many physiologically useful elements. The amount of phenolic chemicals and their antioxidant properties in the milk have not been thoroughly studied. The ferric-reducing antioxidant power assay (FRAP) and the free radical scavenging assay (DPPH) were used in this study to check how antioxidant-rich 48 samples of milk from Moroccan Oulmes cows were. We also determined the total phenol content (TPC) and total flavonoid content (TFC). The investigation was done throughout four seasons because feeding is known to have an impact on the concentrations of these chemicals. The fat contents of autumn milk were significantly high (p<0.05), whereas the protein and lactose contents of both autumn and spring milk were significantly high. Spring season milk had the highest concentration of TPC (454.4 ± 20.6 mg GAE/100 ml) and TFC (145.21±3.16 mg CE/100 ml), whereas winter season milk was found to have the lowest concentration of TPC (379.58±8.16 mg GAE/100 ml) and TFC (100.61±2.17 mg CE/100 ml). DPPH free radical scavenging activity of winter milk had the lowest value (62.49±1.44 mg TE/100 ml), whereas, autumn and spring milk samples showed significantly high (p<0.05) values. The autumn had the highest FRAP value (174.56±6.49 mg AE/100 ml), whereas the summer had the lowest value (138.27±7.68 mg AE/100 ml). On the other hand, spring-season milk also showed significantly high (p<0.05) values in the FRAP assay, which were very comparable to the autumn values. The present findings concluded that seasons played a significant role in designing the chemical and bioactive composition of cow milk. Therefore, moderate changes in the feed of the milking animals may provide milk with the required nutrition.
