Abstract

The study aimed to perform a meta-analysis on the fate of ochratoxin A (OTA), zearalenone (ZEN), deoxynivalenol (DON) and total aflatoxin (TAF) during steps of bread and pasta-based products processing. A total of twenty and eight articles (549 data) collected from 1983 through June 2017 were included. Some of the investigated processing such as milling and fermentation caused an increase in the concentration of DON and TAF; although they reduce the concentration of ZEN and OTA. Also, heat processing (cooking) decrease the DON, OTA, and TAF and increase the concentration of ZEN in bread. Cooking reduces the concentration of DON and ZEN in the biscuit. Cooking of pasta reduces the content of DON; however, it increases the concentration of TFA. The findings showed that the mycotoxins and their fate were influenced differently by the unit operations steps involved in the preparation of the different cereal-based products.
