Effect of modification treatments on insoluble dietary fiber: A microstructural perspective

Abstract

This paper analyzes the microstructure of Insoluble dietary fiber (IDF) from the perspectives of chemical groups and microscopic morphology, compares the changes of IDF before and after modification under different treatments and raw materials, analyzes the commonalities and differences, establishes the relationship between IDF raw materials and modification methods and final results using microstructure as an entry point, predicts to some extent the performance of a certain type of IDF treated in a certain way, and provides a theoretical basis for the target-oriented modification of IDF.
