This study investigated the effects of post-harvest pod storage as a means of pulp preconditioning on the souring production, flavour precursors development and free fatty acids during drying of fermented Ghanaian cocoa beans. A 4 x 4 full factorial…

Cocoa and chocolate have been acclaimed for several years for their possible medicinal and health benefits. It is only recently, however, that some of these claims have been more clearly identified and studied. Recent epidemiological and clinical…

Monoglycerides (MGs) and phytosterols (PS) are known to form firm oleogels with liquid oil. However, the oleogels are prone to undergo polymorphic transition over time that lead to crystals' aggregation thus, compromises physical properties. Thus, we…

The practice of pod storage (PS) has been applied in many cocoa producing countries, especially by Ghanaian farmers over the years. However, the study of PS has not received much attention, hence, until now, its potential impact on specific flavor…

Fine flavor cocoa is worldwide renowned to produce origin chocolates with special aromas, e.g. fruity or floral, in addition to its chocolate aroma. This research aims to elucidate fine flavor dynamics during fermentation by analyzing the sugar, free…

Fat bloom development and associated changes in microstructure, texture, appearance and melting properties were studied. Dark chocolates varying in particle size (PS) (D90 of 18, 25, 35 and 50μm) were processed and pre-crystallised to under-temper…

In dark chocolate, rheological properties during processing are influenced by particle size distribution (PSD), fat and lecithin contents with consequential effects on finished texture and melting characteristics. Multivariate regression, correlation…

Changes in acidification, proteolysis, sugars and free fatty acids (FFAs) concentrations of Ghanaian cocoa beans as affected by pulp preconditioning (pod storage or PS) and fermentation were investigated. Non-volatile acidity, pH, proteolysis, sugars…

Consumer demand for healthier alternative sweeteners and attempts to replace the most common sweetener used in chocolate, namely sucrose, continue to increase in recent times. One sucrose alternative that has not been fully explored in chocolate is…

Investigations were conducted to elucidate changes in total polyphenols, o-diphenols and anthocyanin concentrations during fermentation of pulp preconditioned Ghanaian cocoa beans. A 4x4 factorial experiment was conducted with the principal factors…
