Abstract

Basic data on thermal, structural and rheological properties of cooked maize tortillas were investigated, with the aim of understanding the role of the slaked lime [Ca(OH)2] that is incorporated during the alkaline cooking process. The changes in the thermal parameters, such as thermal conductivity, thermal diffusivity and specific heat, measured by photoacoustic techniques, as well as the changes in texture and X-ray patterns are presented as a function of the Ca(OH)2 concentration. The results show strong evidence that there is a threshold concentration of Ca(OH)2 of 0.25%, above and below which there are different behaviour patterns of the measured properties of the tortillas.
