Relationship between Crystallization Behavior and Structure in Cocoa Butter
Cocoa butter was crystallized statically from the melt to various temperatures in the range of -20 to 26 °C and annealed for up to 45 days. During this period, the polymorphism of the solid state was monitored using differential scanning calorimetry and powder X-ray diffraction. Moreover, the microstructure of the materials was imaged using polarized light microscopy. Below -15 °C, a mixture of...
متن کاملEffect of Sorbitan Monoesters Addition on the Crystallization and Polymorphic Behavior of Cocoa Butter
Crystallization behavior of fats and oils is an important structuration characteristic when developing products with desirable and stable microstructure, texture and quality during processing and storage. Depending on the lipid matrix composition and on the production process, different crystalline network will be formed, with specific physicochemical properties. Therefore, the crystallization ...

متن کاملCrystal Morphology of Cocoa Butter
Introduction The multiple melting points of triglycerides have been known and studied for more than a century by numerous workers. The ability of fat to undergo polymorphic changes is important mainly due to its effect on product texture and appearance. Polymorphic resolidification during storage of cocoa butter into higher melting forms can destroy the smooth glossy appearance of a confectione...
متن کاملComparative study of chemical and technological properties of Brazilian cocoa butter and industrial blends: crystallization kinetics and polymorphic behavior
Cocoa butter is the characteristic fat ingredient of chocolate industries, presenting itself as the most important component in all formulations. Its crystallization is a critical factor associated with the structure and properties of many confectionery foods. The stability of rich-fat processed products is influenced by changes in crystallization processes. With respect to these characteristic...
