Abstract

The objective of this study was to evaluate the survival rate of spray-dried Lactobacillus plantarum TISTR 2075 grown in Job's Tears extract, with the addition of maltodextrin and various protectants (protein, trehalose, fibersol, and acacia gum). Probiotic properties, including gastrointestinal tract tolerance and antimicrobial activity, were not affected by the spray-drying process. Storage temperature and relative humidity were found to influence the glass transition temperature and subsequently the viability of cells. Increasing the relative humidity and temperatures during storage resulted in higher loss of cell viability.
