Effect of ultra-high pressure on the IgG activity of bovine colostrum

Bovine colostrum is rich in diverse nutrients and active ingredients, especially high content of IgG.This study investigated the IgG activity in the bovine colostrum within 48h after calving under different high pressure treatment conditions, taking ELISA to detect the sample. Results showed that when bovine colostrum was treated at the condition of 500MPa, 35℃ and for 20min, the IgG activity increase rate got the maximum.
