Among the three roasting methods tested, we conclude that SIRHA roasting both reduced the processing time and was the only roasting method that met the pasteurization requirements at all roasting temperatures for medium or higher degree roasted almonds. The zero-order reaction model described the total color change data with satisfactory correlation coefficients for all roasting methods at all roasting temperatures. Therefore, we suggest that the greatest benefit of IR technology in industrial almond roasting would be to install the IR heaters in front of the regular almond roasting process in order to heat the almonds to desired roasting temperatures rapidly, thus reducing the processing time, and then continue roasting the kernels with hot air.
