Chocolate – The Noblest Polymorphism II
Chocolate – The Noblest Polymorphism II. Chocolate is a unique substance, solid at room temperature and liquid at body temperature. However, this is not the result of simple crystallization and melting. In fact, cocoa butter is polymorphic and can crystallize into several crystal forms with different physical characteristics. Crystallization ...

Understanding the structure of chocolate
Crystallization of cocoa-butter in the β phase from the melt under static conditions is only possible using the memory effect of cocoa-butter. Under all other conditions polymorphs with lower melting temperatures develop, whereas the β phase is the preferred one in chocolate. SAXS experiments proved 1,3-distearoyl-2-oleoylglycerol …
