The aim of present study was to investigate the effect of freeze drying on total antioxidant
and immunoglobulin levels of bovine colostrum in desi breed (Zebu cattle). A total of 12
colostrum samples were collected from the desi breed (Zebu cattle) reared at LPM section
of IVRI, Izatnagar. Collected colostrum was converted aseptically into dry powder form
by freeze drying at (-) 40ยบ C with low pressure. Antioxidant content was analysed using
free radical scavenging activity (DPPH assay) and total antioxidant capacity (FRAP
assay).Qualitatively and quantitative immunoglobulin level was assessed by zinc sulphate
turbidity and IgG estimation respectively. Average reduction in DPPH scavenging activity
was found to be 35.04 % on freeze drying whereas average reduction of FRAP value was
found to be 14.96 % on freeze drying. Immunoglobulin content of bovine colostrum was
decreased by 23.86 % of ZST unit after freeze drying whereas with respect to IgG level,
the average percentage reduction was 26.05 % after freeze drying of bovine colostrum.
Present study concludes that freeze drying reduces antioxidants and immunoglobulin level
of bovine colostrum.
