Browning in raw and processed yams resulting from enzymes, polyphenol oxidase (PPO) and peroxidase (POD), activities is a major limitation to the industrial utilization of Dioscorea varieties of yams. Two elite cultivars of D. rotundata species were…

Changes in acidification and sugars of cocoa pulp during fermentation of pulp pre-conditioned cocoa (Theobroma cacao) beans were investigated using a 3 × 3 full factorial experimental design with tree level treatment (control (TI), inoculum added in…

The unique impact of roasting conditions on the aroma quality of cocoa beans has been demonstrated in many studies. However, information on the additional impact of pod storage (PS) and its combined effect with roasting temperature (RT) is unknown.…

Fortification of cereal-based traditional foods with legume protein can improve their nutritional value. It is, however, important to find out the extent to which the addition of cowpea affects the desirable quality characteristics of traditional…

Response surface methodology was used to optimize the processing conditions in the preparation of cowpea tempeh. The independent factors studied were boiling time (varying from 5 to 30 min), incubation time (varying from 12 to 48 h) and incubation…

Farmer Preference, Utilization, and Biochemical Composition of Improved Cassava (Manihot esculenta Crantz) Varieties in Southeastern Africa
Cassava (Manihot esculenta Crantz) varieties are ethnobotanically classified by farmers into two distinct…

Spontaneous lactic acid fermentation is an important process in cereal processing. It is applied to develop and enhance taste and flavour, modify texture and improve the microbial safety of foods. When applied to nixtamalized corn mixed with…

Response surface methodology was used to study the effect of extruder characteristics on product quality of rice‐groundnut‐cowpea extrudates using a single‐screw extruder. The combined effect of cowpea (0–20%), groundnut (0–10%) and feed moisture…

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…

Palm sugar is highly produced and patronised in the south-eastern part of Asia, e.g. Indonesia which is also the world’s third largest cocoa producer. Recently, interest in palm sugar sweetened chocolate and better approaches for production methods…
