Formulation of physical properties of methyl glucoside polyester by mixture response surface methodology.
Methyl glucoside polyester (MGPE), consisting of a methyl glucoside molecule esterified with four fatty acids, is a potential fat substitute. A mixture response surface methodology was employed to model the physical properties (melting point, density, and viscosity) of MGPE prepared from composite blends of fatty acid methyl esters (FAME). The measured physical properties were similar to those of soybean oil, except for a higher viscosity. The physical properties correlated significantly with the degree of saturation of their composite fatty acids. Results showed that the physical properties of MGPE prepared from a FAME mixture derived from high oleic acid safflower oil and soybean oil (molar ratio 1:1) was similar to those of soybean oil. The physical properties of MGPE can be adjusted by modifying the saturated fatty acids of synthesized MGPE to simulate the physical properties of soybean oil.
