Resumo(s)
Colostrum samples of recently registered cow breed “ Himachali Pahari ” were assorted from high altitude zone
(901 – 2200 m). 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/100 g), protein (71.72 g/100
g) and total amino acids (69.64 g/100 g). 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
~57 M- 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.
