Food and Machinery
Mycotoxins are metabolized by filamentous fungi and have certain toxic effects. Based on the stable formation of human hepatocellular carcinoma cell lines (HepG2 cells), a variety of plasma proteins were secreted, which could effectively evaluate the in vitro toxic effects of mycotoxins. We reviewed the harm of major mycotoxins to food and their toxic effects on human cells, and this was significant for predicting and preventing the effects of mycotoxins on human and animal health in the future.

Effect Of Processing On Microbiota Accessible Carbohydrates In Whole Grains, Caroline Smith
Department of Food Science and Technology: Dissertations, Theses, and Student Research
There is potential to increase microbiota accessible carbohydrates (MAC) in whole grains through food processing. Therefore, different processing conditions for boiling and extrusion of whole wheat flour were studied for their effect on MAC. Processing conditions had a minimal effect on fermentation response using 2 fecal samples of disparate composition. However, the processing method had an impact on the fermentation of non-digestible carbohydrates and subsequent short chain fatty acids production, but only for a microbiome with high diversity and a predominance of microbes associated with dietary fiber intake. Subsequently, five processing methods: boiling, extrusion, unleavened bread, yeast bread, and sourdough …
