Abstract
Lipid-based wax compositions and their methods of making are provided for compositions substantially free of fat bloom. The compositions comprise 0.1-10 percent by weight triacylglycerides, 30-95 percent by weight monoacylglycerides and diacylglycerides combined, and 0.1-65 percent by weight fatty acids. The methods comprise blending the monoacylglycerides, diacylglycerides, triacylglycerides, and fatty acids by heating the lipid-based wax composition at a sufficiently high temperature to destroy substantially all crystal structure within the lipid-based wax composition. The methods further comprise pouring the lipid-based wax composition into a mold or a container having a surface and a core, wherein the pouring is conducted at a temperature at least 15° C. greater than the congeal point of the lipid-based wax composition. The methods further comprise cooling the lipid-based wax composition under conditions sufficient to cool the core to at least 5° C. below the congeal point of the lipid-based wax composition in 30-90 minutes.
