Abstract
Composition and structure of synthetic glucitol fatty acid polyesters (GPE)-a potential fat substitute-were investigated. Also degree of substitution (D.S) of GPE was determined according to the relative ester distribution within it to evaluate the feasibility of GPE using as a fat substitute. The GPE was separated into single ester group by a normal-phase HPLC and D.S of it was identified to be 6. Absorption band at
최근 sucrose polyesters(SPE)와 더불어 유지대체 물질로서의 사용이 검토되고 있는 glucitol fatty acid polyesters(GPE)를 합성한 후, 화학적 구조 및 상대적 에스테르 분포에 따른 치환도를 조사하였다. 본 연구에서 합성한 GPE는 순상 HPLC에 의해 단일 에스테르 그룹으로 분리되었으며, 분리된 에스테르 그룹의 치환도는 6으로서 GPE 전체가 glucitol fatty acid hexaester임을 알 수 있었다. GPE의 IR 스펙트럼에서
