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 52 oC 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.

Abstract in Chinese

本文对喷雾干燥中改性约氏掷孢A(MSJA)的微观损伤机制进行了探究。结果表明:在含水率为0.21或温度达到52 ℃时和含水率为0.07或温度达到71 ℃时,细胞膜双层磷脂分子层的凝胶相和反六角相转变导致的选择透过性损伤和坍塌等非可逆性损伤分别是喷雾干燥过程中MSJA开始失活和大量失活的主要原因。
