Studies on Physical and Microbial Parameters of Bovine Colostrum Powder

This study investigates the physical and microbial parameters of bovine colostrum powder. Colostrum is the first mammary secretion for 24 - 48 hours after parturition and is a complex fluid rich in immune factors and growth factors. Studies have indicated that the immune boosting properties of bovine colostrum are beneficial for human beings with no reports of allergic or anaphylactic reactions. Colostrum powder was prepared by spray drying the whole colostrum. Physical and Microbial parameters were analyzed in colostrum powder. The total viable count found to be increased as the advancement of storage and coliforms were not detected. While comparing the water activity on initial and final day no changes were observed. With regard to physical parameters viz. texture analysis, insolubility index and bulk density no difference was found between cow and buffalo colostrum powder. Storage study of colostrum powder was carried out up to 6 months period
