Effects of convective and microwave roasting on the physicochemical properties of cocoa beans and cocoa butter extracted from this material
Cocoa beans are the basic raw material for the production of chocolate and other chocolate products. To obtain these products, the seeds must be subjected to a complicated technological process in which one of the key steps is roasting. A widely used method of roasting cocoa beans is convection roasting which is based on subjecting the raw beans to a flow of hot air in the temperature range bet...

متن کاملEnhancing Cocoa Beans Quality through Improved Cultural Practices in Major Cocoa Producing States of Nigeria
In West Africa, low adoption of agricultural innovations by farmers has been partly due to the complexity of the innovation structure or new knowledge beyond the farmers’ socio-economic adaptive capacities. Different attempts have been made to improve cocoa beans quality in Nigeria among which was the recommendation of ‘improved cultural practices’ or ‘best known practices’ (ICMP). This had rec...
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 کاملDetermination of milk fat and cocoa butter equivalents in milk chocolate
An analytical approach for the determination of milk fat and cocoa butter equivalents in milk chocolate is presented. By performing a single triacylglycerol analysis using gas liquid chromatography several useful pieces of information can be determined, i.e., (i) the milk fat content of the chocolate sample, (ii) the contribution of triacylglycerols originating from milk fat, (iii) the presence...
