| Abstract: | In this paper,yogurt fermentation conditions of lactobacillus acidophilus and bifidobaterium adolescentis were researched.The thermal power-time curves were determined by microcalorimetric method,and the growth rate constant were calculated.The optimum growth temperature and optimum growth pH of the lactobacillus acidophilus,bifidobacterium adolescentis and their mix bacteria were obtained.At last yogurt was produced and its quality was assessed. |
