Abstract
•Whey powder prepared by freeze drying of bovine colostrum obtained from high.•altitude cow breed Himachali Pahari.•Freeze-dried BCWP contained a considerable amount of amino acids, minerals and.•IgG.•BCWP has a resistance of ∼57M-ohm (Ω) which decreases with frequency and.•temperature.•BCWP can find utilization as functional food ingredient in health and infants’ formula.
Colostrum samples of recently registered cow breed “Himachali Pahari” were assorted from high altitude zone (901-2200 meters). Prepared bovine colostrum whey powder (BCWP) was analysed for chemical composition, amino acids, minerals, surface morphology (SEM-EDS), FTIR and dielectric properties. Results showed that freeze-dried BCWP contained a considerable amount of nutritional parameters viz IgG (18.55 g/100g), protein (71.72 g/100g) and total amino acids (69.64 g/100g). Additionally, the concentration of essential minerals was found to be adequate, and there was no presence of heavy metals. The BCWP exhibits good dielectric properties (resistance ∼57M-Ω). SEM-EDS showed the broken up-wards layer structure with the uniform distribution of minerals on the surface. The FTIR spectra confirmed the presence of a higher proportion of β-sheets and β-turn structures in BCWP. Thus, on account of good functional and nutritive properties, BCWP could be foreseen as the future of functional food.
