• The annatto dye was able to reduce of S. enteritidis in mayonnaise.
• The bactericidal effect of the annatto dye was stronger in 25 °C than 4 °C.
• GA-ANN could predict S. enteritidis population with correlation coefficient of 0.999.
• The overall agreement between ANFIS predictions and experimental data was very good .
• Temperature was the most sensitive factor for prediction of S. enteritidis population.
Annatto is commonly used as a coloring agent in the food industry and has antimicrobial and antioxidant properties. In this study, genetic algorithm-artificial neural network (GA-ANN) and adaptive neuro-fuzzy inference system (ANFIS) models were used to predict the effect of annatto dye on Salmonella enteritidis in mayonnaise. The GA-ANN and ANFIS were fed with 3 inputs of annatto dye concentration (0, 0.1, 0.2 and 0.4%), storage temperature (4 and 25 °C) and storage time (1–20 days) for prediction of S. enteritidis population. Both models were trained with experimental data. The results showed that the annatto dye was able to reduce of S. enteritidis and its effect was stronger at 25 °C than 4 °C. The developed GA-ANN, which included 8 hidden neurons, could predict S. enteritidis population with correlation coefficient of 0.999. The overall agreement between ANFIS predictions and experimental data was also very good (r = 0.998). Sensitivity analysis results showed that storage temperature was the most sensitive factor for prediction of S. enteritidis population.
