Changes in acidification and starch behaviour were investigated during co-fermentation of cassava and soybean into gari, an African fermented product. Non-volatile acidity, pH and starch content were evaluated using standard analytical methods.…
Hunger and malnutrition have reached crisis proportions in much of Africa where about 200 million people are undernourished. Africa is the only region in the world to have experienced such substantial increase in the number of undernourished in the…
Polyphenols are phytochemicals responsible for the astringency, bitterness, green flavours and antioxidant activities in Theobroma cacao beans. Polyphenols degradation in cocoa beans during roasting is crucial to the flavour outcome and it is…
Pod storage and fermentation are critical to the development of nib acidification and flavour precursors that generate into distinctive chocolate flavour notes during industrial manufacture. This work investigated changes in nib acidification,…
Yoghurt produced by fermenting milk from peanut and soy milk are considered to have poor sensory attributes due to the off-flavours legumes generate in food products. Improvement in flavour requires a combination of treatments. This study employed…
Response surface methodology and central composite rotatable design (CCRD) for K= 3 were used to investigate the combined effect of blanching time (0-1 min), processing time (10-30 min) and sodium metabisulphite (Na2S2O5) salt concentration (0%-2%)…
Studies were conducted to establish changes in nib acidification and biochemical composition (sugars concentration, proteins and free fatty acids) during fermentation of pulp pre-conditioned cocoa beans using a 4 x 3 full factorial experimental…
Changes in total polyphenols, O-diphenols and anthocyanin concentrations during fermentation and drying of pulp pre-conditioned cocoa (Theobroma cacao) beans were investigated using standard analytical methods. Increasing pod storage, fermentation…
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…
