Information on the mycotoxin contamination of rice in Africa is limited although risk high. In this study, domestic milled processed by actors using suboptimal methods was purchased and total fumonisin (FUM), zearalenone, aflatoxin concentrations determined at 0, 90, 180 days after storage. Three different climatic locations, Cotonou (Benin) Guinea savanna, Yaoundé (Cameroon) Tropical forest, N'diaye (Senegal) Sahel, were selected as storage sites.

Abstract To elucidate the effect of different parboiling steaming time on physicochemical and nutritional quality rice, four varieties, NERICA 1, 7, IR 841, WITA 4, were soaked at same initial temperature (85°C) steamed for 5, 15, 25, 35, 45 min. 7 25 min recorded highest head rice yield (71.9%). Nonparboiled 841 shortest cooking (17.0 min), while 1 35 longest (26.1 min). was hardest (63.2 N), nonparboiled softest (28.7 N). higher peak final viscosities across all times compared to other...

Bambara bean is a rich low-cost protein source and functional ingredient in the food industry. We investigated effects of temperature different pH on physicochemical properties isolate. Vicilin was major as revealed by SDS PAGE analysis. The emulsifying capacity isolate highest at 80 °C, 9 while emulsion stability 4. Generally, increase decreased solubility 4 7, observed 100 °C. hydrophobicity lowest 9, regardless temperature. Protein possessed highly compact β-sheet α-helix secondary...

Abstract In order to increase the quality of locally produced rice, artisanal parboiling process in West and Central Africa was reconceptualized. A novel unit constructed using stainless steel (Inox 304) fitted directly on an improved stove made from fired bricks. The heat profile at different locations unit, physicochemical properties, cooking properties parboiled fuel efficiency were evaluated compared with that traditional system. flow new top bottom while reverse occurred unit. percent...

Abstract Consumers with diabetes mellitus have shown interest in products low postprandial glucose. To produce rice for this group of consumers, the effect parboiling steaming time (0, 5, 15, 25, 35, and 45 min) variety ( NERICA 1, 7, WITA 4, IR 841) on resistant, damaged starch fractions glycemic response rats was investigated. Resistant were influenced by but not case index. Nonparboiled 7 steamed 25 min recorded highest (10.07%) lowest (2.49%) resistant fraction, respectively. correlated...

Abstract The reduction of postharvest losses in rice and safou is imperative to increase productivity their respective value chains. In this study, fine broken grains were used produce flour subsequently rice‐based biscuits. biscuits further fortified with powder, the physical, nutritional, sensory quality stability during storage different types analyzed using standard methods. Fine or nonsandy had peak particle size 500 µm, while medium (slightly sandy) large (sandy) sizes 1,000 µm 1,400...

Abstract Wild meat and freshwater fish are widely consumed in the Congo Basin, but some areas, they at risk of disappearing due to unsustainable hunting fishing changes their habitat. is also being eliminated from local diets potential policy such as wild bans. In order understand impacts these on nutrition design appropriate policies, it critical contributions animal source foods individual nutrient intake. this study, we focus young children who among most nutritionally vulnerable. We use...

Widely consumed forest fruits in Gabon were analysed for nutrient and bioactive compositions their potential contributions to meeting the requirements of consumers. Edible pulps Panda oleosa Pierre, Gambeya lacourtiana (De Wild.) Aubrév. & Pellegr. Poga Pierre contained substantial amounts compounds; flavonoids (13.5–22.8 mg/100 g), proanthocyanins (2.4–7.6 polyphenols (49.6–77.3 g) vitamin C (6.7–97.7 g). The highest content β-carotene (76.6 µg/100 was registered Pseudospondias...

This article explores the challenges faced by agricultural cooperatives in South West Region of Cameroon, with a particular focus on cassava value chain. Cassava plays significant role Region's sector, serving as vital staple crop and source income for many smallholder farmers. However, despite its importance, engaged production processing encounter numerous obstacles that hinder their productivity overall development. analyses key these proposes prospects enhancing The study draws insights...

<title>Abstract</title> A simple liquid chromatography method with UV detection was developed for the rapid screening of arbutin, hydroquinone, dexamethasone, hydrocortisone and clobetasol propionate in four skin-whitening cosmetic products. The chromatographic conditions their less than 15 min were optimized on a Kinetex® 2.6 µm Polar C₁₈ column (150 x 4.6 mm) gradient mobile phase made 0.025% TFA water acetonitrile ) performed at two wavelengths, 240 nm 270 nm. Under these...

Bobolo is a thick fermented, popular traditional food, derived from cassava (&amp;lt;i&amp;gt;Manihot esculenta Crantz&amp;lt;/i&amp;gt;) in Cameroon. The physical, sensory, chemical and microbiological characteristics of were analyzed, order to identify the suitable varieties local fermentation method with best nutritional industrial properties. range L* (lightness / darkness), a* (redness greenness), b* (yellowness blueness) 75.00±0.65-80.07±0.60, 3.7±0.57-4.90±0.60, 11.9±08-17.2±0.75...

Abstract Mycotoxins such as aflatoxins (AFs), fumonisins (FBs), zearalenone (ZEN), and deoxynivalenol (DON) pose a risk to public health due their carcinogenic potency (AFs FBs) anti-nutritional effects. The hazards associated with mycotoxins are accentuated where food management practices, control, regulatory systems from farm plate sub-optimal. Information on the frequency of these in rice commercialized markets sub-Sahara Africa (SSA) is limited. current study examined AF concentrations...

The magnitude of rice grain losses during storage is huge and warrants critical attention. We investigated the diversity fungi insect contamination related to domestic imported from local mills markets, stored under room conditions for 10 weeks in Cameroon. highest percentage discolored was on milled white (3.5%), after storage. In general, samples contained fungal load with a proportion 65.90% compared 34.3% samples. Weight loss due damage up 19.9% rice. Among 67 isolated strains, genus...

Loss in quality and quantities of rice during storage is an important issue to focus on. Moulds contaminating were investigated their injuries on evaluated. Local imported samples sold markets mills stored for 3 months under laboratory conditions. The contaminated grains counted analyzed characterize moulds.
