Liquid sucrose cannot be freeze-dried directly . However, if it is mixed with other ingredients such as maltodextrin, liquid sucrose can be freeze-dried into powder , or other drying methods can be used . 1. Why can’t liquid sucrose be freeze-dried alone? Freeze drying (lyophilization) works by freezing a substance and then removing the water …
Introduction Freeze-drying (also known as lyophilization) is one of the most commonly used methods for preserving probiotics. It makes transportation and storage more convenient – but many people still wonder: Can probiotics survive The answer is yes. When properly processed, stabilized and stored in appropriate packaging, probiotics can survive freeze-drying and maintain their effectiveness. 1. How Freeze-Drying Technology Affects Probiotic Viability The freeze-drying process involves freezing probiotic cultures and then removing moisture through vacuum sublimation. This low-temperature drying technique puts probiotics into a dormant state without killing them. With proper formulation, most probiotic strains can maintain over 80% viability after freeze-drying. This is because protective agents like trehalose, skim milk or sucrose added during the formulation process help protect them. Without protectants, probiotic survival rates can drop dramatically, sometimes losing over 90% of activity. However, if residual moisture content is kept below 4%, survival rates improve significantly, allowing the product to maintain a shelf life of 24-36 months. 2. Efficacy of Freeze-Dried Probiotics Freeze-dried probiotics remain in a dormant state and will reactivate and restore activity when ingested or mixed …
