Abstract

The aim of the present study was to extend the shelf life of bread by using organic additives and optimization techniques. Quadruple effects of temperature (−18, + 4, + 20 °C), clove oil (0, 1, 2%), orange oil (0, 1, 2%), residence time (7, 14, 21 days) were investigated to determine optimum bread as moisture response. Quadratic model was found to be suitable with an accuracy of 0.9854 for moisture response. Rheological properties remained intact for 7 days at 20 °C in bread with 1% clove oil and 1% orange oil added. The effect of 4 effective parameters from 3 levels was examined with Box-Behnken in Design Expert. Optimum and control samples at two different temperatures were determined with SEM, TG–DTA and polarized light microscope. Consumer survey was conducted as appearance, colour, smell for optimum, control samples for bread and cake. It was concluded that bread samples could be stored with clove and orange oil at + 20 °C with period of 7 days without losing their quality properties.
