FORMULATION ACID OPTIMIZATION OF SUCROSE POLYESTER PHYSICAL-PROPERTIES BY MIXTURE RESPONSE-SURFACE METHODOLOGY

The physical properties of sucrose polyester (SPE), prepared from diff erent composite blends of fatty acid methyl esters (FAME) of safflower oil, palm oil, and peanut oil, were evaluated by mixture response sur face methodology. Optimum combinations of fatty acids to achieve speci fic physical properties of SPE were determined. The SPE most similar i n physical properties to peanut oil was obtained with a 55:45 molar ra tio of mixed FAME from safflower oil and peanut oil. The physical prop erties of SPE were significantly affected by the degree of saturation and the average chainlength of their composite fatty acids.
