Effect of NaH₂PO₄, Na₂HPO₄, MgSO₄, and Ascorbic Acid on Survival of Lactobacillus acidophilus during Freeze-Drying

Abstract:

Effect of NaH₂PO₄, Na₂HPO₄, MgSO₄, and Ascorbic acid on survival of Lactobacillus acidophilus was investigated before and after freeze-drying. Editing different concentrations of protective agents respectively during freeze-drying. After completion of the pilot, the survival ratio of Lactobacillus acidophilus and the number of viable cells were being measured. Results were as follows: the highest survival rate and the largest number of viable cells was Na₂HPO₄ as the protective agent.
