“研发喷雾干燥技术的突破口在于如何从细菌悬液中去除盐类和甘油之类的冷冻保护剂，”爱德华斯解释道。
"The breakthrough for developing the spray drying process involved removing salts and cryoprotectants like glycerol from bacterial suspensions," explains Edwards.
这与使用盐类和冷冻保护剂干燥细菌的传统技术截然相反。
This is counter to conventional thinking: that bacteria be dried in the presence of salts and cryoprotectants.
通过这种方式，碳水化合物发挥低温保护剂和防止因冷冻而破坏结构和组织引起脱水的作用。
In this way, carbohydrates function as cryoprotectants and protect against the dehydration that destroys structure and texture caused by freezing.
