Milk composition, antioxidant activities and protein profile of Gaddi goat milk

This study reportsGaddi goat milk composition and antioxidant activity in different lactation stages. A significant (p <  0.05) higher pH (7.05 ± 0.03) and lactose (4.28% ± 0.07%) were noted in late lactation. Total phenol (mg TAE/100 ml) was 56.99 ± 2.32, 8.15 ± 0.44, and 7.05 ± 0.03 in whole milk, whey and casein, respectively. 2, 2‐Diphenyl‐1‐picrylhydrazyl radical scavenging activity and pro tein (4.06% ± 0.19%) were higher, whereas fat was lowest (6.00% ± 0.28%) in late lactation milk. It is envisaged that late lactationGaddi goat milk with splendid biological activities, could be a source of milk ‐derived bioactive nutraceuticals to thwart oxidative stress and aging.Practical applicationsMilk is an important source of complex proteins, enzymes and peptides of diverse biological activities. Goat milk has assumed importance in humans, particularly in infants, as alternative to cattle milk. Milk composition and antioxidant activity ofGaddi goat milk and its protein fractions were assessed for bioactive potential. The casein protein fraction ofGaddi goat milk proved to be a potent antioxidant component and may be used as futuristic nutraceuticals. This is the first study unravelling antioxidant traits ofGaddi goat milk, whey and casein in different lactation stages.
