Synergistic combination of cryoprotectants improved freeze-dried survival rate and viable counts of Lactiplantibacillus plantarum
Well-designed cryoprotectants are crucial for successful probiotic application. In this study, based on literature analysis, characteristics and economic analysis of cryoprotectants, the sucrose (8.2%)–skim milk (8.0%)–inulin (8.2%) combination was proposed and optimised to enhance freeze-drying resistance of probiotics. Survival, viable cell counts and inactivation rate during storage at 4°C of Lactiplantibacillus plantarum grx16 protected by the combination was 94.9%, 1.89 × 1011 cfu/g and 0.0116. The optimised sucrose–skim milk–polymer prebiotics combination could also effectively protect several other probiotics, with the survival rate being 89.2–95.6%. These results will aid in the rational development of synergistic cryoprotectant formulations for probiotics.
期刊介绍：
The International Journal of Dairy Technology ranks highly among the leading dairy journals published worldwide, and is the flagship of the Society. As indicated in its title, the journal is international in scope.
Published quarterly, International Journal of Dairy Technology contains original papers and review articles covering topics that are at the interface between fundamental dairy research and the practical technological challenges facing the modern dairy industry worldwide. Topics addressed span the full range of dairy technologies, the production of diverse dairy products across the world and the development of dairy ingredients for food applications.
