The aims of this study were to compare the effectiveness of different drying methods and to investigate the effects of adding a series of individual protectant such as skim milk, sucrose, maltodextrin, and corn starch for preserving Lactobacillus acidophilus FTDC 3081 cells during spray and freeze-drying and storage at different temperatures. Results showed a remarkable high survival rate of 70–80% immediately after spray- and freeze-drying in which the cell viability retained at the range of 10⁹ to 10¹⁰ CFU/mL. After a month of storage, maltodextrin showed higher protective ability on both spray- and freeze-dried cells as compared to other protective agents at 4°C, 25°C, and 40°C. A complete loss in viability of spray-dried L. acidophilus FTDC 3081 was observed after a month at 40°C in the absence of protective agent.

这项研究的目的是比较不同干燥方法的效果，并研究添加一系列单独保护剂（如脱脂牛奶，蔗糖，麦芽糖糊精和玉米淀粉）在喷雾和冷冻过程中保存嗜酸乳杆菌FTDC 3081细胞的效果。在不同温度下干燥和储存。结果显示，喷雾干燥和冷冻干燥后，立即存活率高达70-80％，细胞存活率保持在10 ⁹至10 ¹⁰ CFU / mL范围内。储存一个月后，与其他在4°C，25°C和40°C的保护剂相比，麦芽糖糊精对喷雾和冻干细胞均显示出更高的保护能力。喷雾干燥的生命力完全丧失 在没有保护剂的情况下于40°C放置一个月后观察到嗜酸乳杆菌FTDC 3081。
