Abstract: Thermal analysis was conducted for roasted, unroasted and defatted date pits powder using differential scanning calorimetry (DSC) and modulated differential scanning calorimetry (MDSC). Endothermic events reflected ice and/or lipid melting dependent on the moisture content of the preparation. High solid materials are capable of holding up to 29.4% unfreezeable water in the matrix. Throughout the experimental temperature range (-90 to 80 °C) there was no evidence of glass related processes, a result which could be attributed to extensive low-mobility or crystalline carbohydrate regions in the matrix. The proximate composition and other chemical compositions were also determined in relation to the thermal analysis. © 2006 Elsevier Ltd. All rights reserved.
