The Effect of Eight Thermal Protectants on the Survival Rate and the Viable Counts of Lactobacillus casei After Heat Treatment in Fermented Goat Milk
In order to improve the survival rate of probiotics and produce probiotic goat milk from fermented goat milk of Lactobacillus casei L61 by spray drying. Spray drying has been applied to large-scale industrial production of milk powder due to its high efficiency and low cost. However, high temperatur...
