Studies on quality attributes of skimmed colostrum powder

Abstract

Bovine colostrum characterized by its high level of bioactive peptides plays a significant role in curing plethora of diseases in human. In the present study, bovine colostrum was collected within 24-36hours after parturition, pooled and stored at -20 0C and the samples were analysed for total solids, fat, lactose, protein, ash, IgA, IgG, TGFβ1, TGFβ2, IGF1 and IGF2. Pooled samples were thawed and conditions for freeze drying were standardized. Physico-chemical attributes of freeze dried bovine colostrum powder was studied and microstructure of powder particles was observed with scanning electron microscope. Such powder can be used in formulating different food products like infant formula, fermented dairy products, sports drink and dietary supplements.
