Mechanism and Application Prospects of Protectants Applied in Viable Strain Formulation

Abstract:

Viable strain formulation is widely used in various fields including food, cosmetics, agriculture, environmental governance, and healthcare, due to their unique bioactivity, stability, and convenience. The author reviews the physiological structure of bacteria and the influencing factors leading to the inactivation of viable strain formulations during production, processing, and storage. It enumerates the mechanisms of proteins, sugars, lipids, and other components as protective matrices in viable strain formulation. Additionally, the different requirements of protectants for strains of different genera and physiological states were summarized, aiming to provide research insights for the development and selection of protectants related to viable strain formulation.
