随着食品加工工艺的提高,类可可脂逐渐成为制作糕点涂层、代可可脂巧克力等巧克力制品的较好原料.
但乌桕类可可脂极易氧化酸败。
研究了在无溶剂系统中,利用1,3位置特异性脂肪酶催化POMF与硬脂酸甲酯进行酯交换(反应)制取类可可脂。
Cocoa butter equivalent(CBE)production from palm oil m idfraction(POMF)and stearic acid methyl ester(SAME)by interesterification catalyzed by 1,3 specific lipases in solvent free system was studied.
为了解这一现象与CTCBE结晶行为的关系,拟用X粉末衍射和差示扫描量热法对乌桕类可可脂和天然可可脂在不同条件下的结晶行为进行了研究。
Crystallization behavior of cocoa butter (CB) and Chinese tallow cocoa butter equivalent (CTCBE) are studied using powder X-ray diffraction (XRD) and differential scanning calorimetry (DSC).
