| 摘 要： | 脂肪酸聚甘油酯(Polyglycerol esters of fatty acids,简写为PGE)在常温下有半固态和固态两种存在状态,本文通过对分别添加这两种PGE的软冰淇淋基料进行粘度、pH、粒径分析和垂直扫描分散稳定性分析(Turbiscan),发现半固态PGE的添加量为0.2%时,乳状液的粘度最低,粒径最小,稳定性最好;固态PGE的添加量为0.4%时.乳状液的粘度最低,粒径最小.通过比较发现,两种PGE对基料的影响有很大差别:半固态PGE能使乳状液的粒子更小,并能有效延长乳状液的稳定性;而固态PGE由于其熔点较高,可以促进脂肪结晶.

| Abstract: | There are semisolid and solid two exist states of polyglycerol esters of fatty acids(PGE) in ambiance.Influence of the two kinds of PGE on the soft-serve mix emulsion in the viscosity,pH,particle size and turbiscan was investigated.There was the lowest viscosity,smallest particle size and longer storage life of soft-serve mix emulsion with 0.2% semisolid PGE,or 0.4% solid PGE.After compare the character differences of two kinds PGE,the result showed that the semisolid PGE could make the smaller particle siz... |
