Abstract: Scientific control of the processing parameters of bovine colostrum is of great significance to the development and processing of colostrum products. The purpose of this experiment is to explore the effects of heat treatment on the physicochemical properties and functional proteins of colostrum. In this study,seven different heat treatment conditions(55 ℃/30 min,55 ℃/60 min,60 ℃/30 min,60 ℃/ 60 min,63 °C/30 min,63 °C/60 min,and 72 °C/15 s)were designed,and changes of colostrum physicochemical indexes,microbial colony count, immunoglobulin IgG and lactoferrin after heat treatment were analyzed. The results showed that after treatment at 63 ℃ for 30 min and 60 min,and at 72 ℃ for 15 s,obvious protein clots appeared; physical and chemical indicators such as TS,citric acid,casein and urea were all significantly decreased,all heat treatment conditions in this study significantly reduced the total plate count,effectively controlling the number of Bacillus coli and Staphylococcus aureus. The IgG level in colostrum was significantly reduced after the heat treatments used in this study while the lactoferrin content was not. In summary,it is recommended that the thermal processing temperature of colostrum be controlled below 63 °C,and the thermal processing parameters should be controlled according to the production purpose. This study can provide detailed scientific data support for the process parameter control of bovine colostrum processing.

Key words: bovine colostrum, physicochemical properties, immunoglobulin, lactoferrin, heat treatment
