African wild mango (Irvingia gabonensis) is now recognized for its numerous food and medicinal uses. This plant produces seeds rich in fat, which is traditionally used as a soup thickener. In the present study, the fat from Irvingia gabonensis seeds was solvent extracted and characterized. Besides a chemical characterization (fatty acid (FA) and triacylglycerol (TG) profiles), the melting and crystallization behaviour of the extracted fat was studied by complementary techniques: pNMR, DSC and X-ray diffraction in order to get basic information regarding its physical properties and more particularly, about its polymorphism. The seeds from Irvingia gabonensis (IG) represent an important source of lipids (69e75 g/100 g), rich in myristic (49.8%) and lauric acid (37%). Due to its FA composition, this fat can be classified among “lauric fats”. The melting profiles of IG fat indicates that a high amount of fat remains solid at temperatures up to 30 °C; the complete melting was detected at around 40 °C. The most stable polymorph of this fat is the ℬ' 1-form. Moreover, IG fat presents a good oxidative stability due to its low content in unsaturated fatty acid. [less ▲]

A knowledge of rheological properties is of importance in processing, handling, process design, product development and quality control. This study investigates the effect of commercial hydrolytic enzymes (pectinase and cellulase) on rheological properties and glass temperature transition of date syrup. Date syrups obtained by enzymatic extraction exhibited a quasi Newtonian behaviour. The enzyme-treated date syrups showed the highest values of activation energy (Ea). Therefore, these syrups showed the most temperature dependency. Dynamic shear results revealed viscous behaviour for date syrups indicating that both syrups displayed liquid-like behaviour. Temperature significantly affected both (G') and (G''). The glass transition temperature (Tg) of date syrups varied between -39.56 and -45.74 °C depending on their composition. Glass transition temperature of date syrups decreased linearly with an increase in water content. [less ▲]
