(2022) Biochemical, dielectric and surface characteristics of freeze-dried bovine colostrum whey powder. Food Chemistry: X, 15, 100364: 1-8.http://hdl.handle.net/10400.19/7293Colostrum 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.engBovine colostrumSurface morphologyFreeze-dried whey powderMicronutrientsDielectric propertyAmino acidsjournal article
