Effects of Intensification of Vaporization by Decompression to the Vacuum (IVDV) and frying on physicochemical, structural, thermal, and rheological properties of chickpea (Cicer arietinum L.) powder

초록

Hard textural attributes of chickpea necessitate the employment of specialized pretreatment prior to roasting. As compared to frying, the Intensification of Vaporization by Decompression to the Vacuum (IVDV) as a vacuum expansion (VE) technique was utilized to improve and preserve the nutritional, textural, and structural properties of chickpeas. It was clearly demonstrated that frying (FR) caused decrease in degrees of lightness in chickpeas as compared to VE samples. Raw and VE samples showed a combination of green and red colors. VE caused C=O stretching in chickpeas and imparted desirable color. The surface fissures were more evident in FR grains as compared to VE grains. The grain structure was modified from largely ovoid to round or spherical forms. Enhanced cross-linking was observed in VE samples due to stable rheological properties. IVDV improved nutritional, color and structural attributes of chickpeas were preserved after texturization.
