Investigation of the Microscopic Damage Mechanism of Baijiu Yeast Spray Drying

Abstract

In this paper, the microscopic damage mechanism of Modified Sporidiobolus johnsonii A (MSJA) in spray drying was investigated. The results showed that at a water content of 0.21 or a temperature of 52oC and at a water content of 0.07 or a temperature of 71oC, irreversible damage such as selective-permeable damage and collapse due to the transformation of the gel phase and the inverse-hexagonal phase of the phospholipid molecular layer of the cell membrane bilayer were the main reasons for the beginning of inactivation and large amount of inactivation of MSJA, respectively, in the spray-drying process.
