The Effect of Shear on the Crystallization of Cocoa Butter

 · A number of studies on the effect of shear on the crystalliza-tion of CB have been conducted. In 1962, Feuge et al. (7) was the first to report a solid-to-solid transformation of CB from a less stable form (Form II) to the more thermodynamically sta-ble one (Form V) by mechanical work consisting of repeated extrusion under pressure ( ≤1000 psi).

Polymorphism of chocolate STK-Online

 · Cocoa butter is composed of triglycerides which are in motion in the liquid state. When these triglycerides solidify, they will form structures. If these structures are regular, we can speak of crystallization. The characteristic of cocoa butter is that it can crystallize in different structures this is called polymorphism. There are six

Isothermal Calorimetric Studies of Cocoa Butter

The quality of chocolate relies almost completely on its cocoa butter content. Solidifying the cocoa butter into the desired polymorph and maintaining it over storage to give a glossy and firm chocolate with a perfect snap is a concern of every chocolatier. In past studies on cocoa butter crystallization, various techniques such as Differential Scanning Calorimetry, X-ray diffraction, Magnetic

Melting Point of Cocoa Butter The Physics Factbook

Cocoa butter naturally melts at the temperature in your mouth, ~37 °C, and this gives it a very unique property. When substitute oils, such as palm and coconut oils, became more commonly used in place of cocoa butter, a special process was necessary to give it this appealing characteristic.

The Polymorphs of Chocolate chemeurope

Cocoa butter has at least six different structures, or 'crystal forms'; the ability of a substance to display different structures is known as 'polymorphism'. These crystal structures differ in how the molecules are arranged, which in turn influences their properties, such as appearance, taste, and texture.
