The effect of the structure and composition of acylglycerol emulsifiers on the functionality of a palm-based shortening and quality of layer cake was investigated. The emulsifiers evaluated were distilled monoacylglycerol (DMG) and four acylglycerols (40% monoacylglycerol content) of octanoic acid (8:0), palmitic acid (16:0), stearic acid (18:0), and linoleic acid (18:2), designated as GMOct40, GMP40, GMS40, and GML40, respectively. The addition of GMP40 and GMS40 led to shortening with a higher solid fat content, finer crystals, and higher proportion of β’ form. These changes enhanced shortening’s function in aiding air incorporation and retention in cake batter, which improved the cake’s volume and crumb structure. However, the high monoacylglycerol content in DMG did not improve the properties of shortening and cake as compared to GMP40. In contrast, GML40 and GMOct40 had adverse effects on the functionality of shortening, which generated cakes with inferior crumb structure.

The objective of the present study was to produce one novel low-calorie structured lipids (SLs), that can be used as a healthy alternative of shortening fat. SLs were produced by the interesterification of tiger nut oil (TNO) and methyl behenate using Lipozyme RMIM at a temperature of 85 °C, an agitation speed of 300 rpm, and a reaction time of 1.25 hours. Resulting SLs characterized through a comprehensive set of advanced physicochemical analysis including AV, slip melting point, solid fat content, total fatty acid composition, x-ray diffraction, differential scanning calorimetry, and triacylglycerol composition were analyzed for both SLs and formulated blends. Results showed that novel SLs had high melting point and solid fat content, to further optimize functionality, unique blend formulations of SLs and TNO were prepared, and the best ratio was selected. This blend demonstrated reduced slip melting point and solid fat content than SLs, suggesting its potential for developing low-calorie, health-friendly shortening fats.
