Abstract :

The compatibility and non-isothermal crystallization properties of oils and fats have important effects on the taste and quality. For extension application scope of coconut and palm stearic oil, development special oil products based on them,Gas phase mass spectrum measured coconut oil and palm stearin oil with different mixing proportion of total fatty acids and Sn - two fatty acid composition of the fatty acid composition and melting characteristics of correlation,the compatibility of coconut oil and palm stearic oil, and the non-isothermal crystallization behavior of different proportions Physical blend oil and enzymatic preparation of structure lipid of the combined systems have studied by Pulsed NMR and DSC respectively. The results showed Different proportions of enzymatic preparation structure Sn-2lauric acid content (12.35-46.72%) is significantly higher than physical blend oil (5.86-30.75%).that there was a certain degree of eutectic phenomenon in complex system on the whole, and at a higher temperature (25-450C) had better compatibility. In the process of non-isothermal crystallization, the double chain length�?²â�?�?crystals changed for three chain length�?²â�?�?crystalsoflow-melting-pointof proportion of coconut oil under the same cooling rate.
