| dc.description.abstract | Value addition of yoghurt with functional ingredients like probiotics and oats (Avena sativa) enhances nutritive and bioactivities of yoghurt. Hence, oats has gained significance due to its β-glucan and antioxidant components. The prepared raw oats‟ powder showed moisture, carbohydrates, fat, protein, ash & crude fibre at 5.31, 61.95, 6.86, 16.34, 1.49 & 8.05 % respectively whereas, the corresponding values were 2.64, 64.01, 6.96, 16.82, 1.50 & 8.07 % respectively in roasted oats‟ powder. Among the levels of yoghurt culture (1.5%, 2% & 2.5%) and probiotic culture B. bifidum (3%, 4% & 5%), the levels of 2 % & 4 % scored maximum respectively. Probiotic yoghurt optimized exclusively with raw oats' powder and roasted oats‟ powder separately (0.5%, 0.75% & 1%), showed 0.5% of raw and roasted oats‟ powders can be incorporated. In-vitro antioxidant activity performed by DPPH radical-scavenging method shown by raw oats‟ powder yoghurt and roasted oats‟ powder yoghurt were 88.79% & 92.71% respectively, which were higher than the control (73.3%). Both optimized experimental samples were effective in significantly lowering the blood glucose level of experimental rats upon feeding for a period of 5 weeks compared to control. Storage studies at 5±1˚C revealed that the product retained acceptability up to 9 days. During storage, there was an increase in % titratable acidity, % FFA and % soluble nitrogen. The viability counts of B. bifidum were higher than the control due to prebiotic effect of β-glucan. Hence, the present study was aimed to explore bioactivities of yoghurt supplemented with oats‟ powder | en_US |
