Aflatoxin B1 (AFB1) incidence in cereal, especially in wheat products, is a serious worldwide challenge for human health. The objective of the current study was to survey the effect of various factors, including fermentation times, yeast levels, ingredients, and time/temperature combinations of the baking process on aflatoxin B1 (AFB1) reduction in order to modify parameters of the traditional cookie‐making process. AFB1 levels were analyzed by an HPLC‐fluorescence detector. The results revealed AFB1 levels significantly decreased during fermentation (%23.7), depending on an increase in the yeast level (2%) and fermentation time (90 min). Furthermore, there was a significant correlation between pH reduction and AFB1 decomposition. However, the formulation of the recipe did not show a significant effect on the detoxification of AFB1. The baking temperature increase in an admissible technological range (280°C for 15 min) more effectively reduced AFB1 content (%53.9). As a result, the exact control of the traditional process was able to significantly decreased AFB1 content as a serious health‐threatening toxin in the final product (%75.9). However, AFB1 toxicity reduction should be considered seriously in the raw materials and such products. Biological (yeast), physical (heat), chemical (spices) methods on AFB1 reduction were surveyed. The cookie‐making process was controlled by modifying technological factors on AFB1 decrement. AFB1 levels in all samples were analyzed by reverse‐phase HPLC with a fluorescence detector.
