dioscorea trifida/carbohydrate

In some tropical countries, people are suffering from both undernourishment and noncommunicable disorders, such as overweight/obesity. Starchy tropical fruits and tubers are of particular interest for their carbohydrate content and for the micronutrients they provide. The present study summarizes

Tropical roots and tubers (TRT) are important staple foods in the tropics. TRT are produced by small farmers and have received only limited attention. The objective of this paper was to evaluate nutritionally important carbohydrate fractions and proximal composition of cooked cassava (Manihot

We have examined the changes in carbohydrate metabolism in food yam (Dioscorea esculenta (Lour.) Burk.) tubers and in an economically important spice cum medicinal plant turmeric (Curcuma longa L.) rhizomes under storage. Both specimens showed varied levels of dormancy and sprouting appeared at the

This study is aimed at assessing the inhibitory effect of teas on key enzymes (α-amylase and α-glucosidase) linked with type-2 diabetes and their antioxidant properties. Four samples of three brands were used; infusions of green tea (GT), 2 brands of black tea (BT), and a formulated herbal

Different low molecular weight carbohydrates including saccharides, polyalcohols, sugar acids, and glycosides have been identified and quantified in different edible vegetables from Asteraceae, Amarantaceae, Amarylidaceae, Brassicaceae, Dioscoreaceae, and Solanaceae families by gas

Glycaemic index (GI) values for fourteen commonly eaten carbohydrate-rich foods processed by various methods were determined using ten healthy subjects. The foods studied were round leaf yellow yam (Dioscorea cayenensis), negro and lucea yams (Dioscorea rotundata), white and sweet yams (Dioscorea

A 70-kDa galactose-specific lectin was purified from the tubers of Dioscorea opposita cv. nagaimo. The purification involved three chromatographic steps: anion exchange chromatography on a Q-Sepharose column, FPLC-anion exchange chromatography on a Mono Q column, and FPLC-gel filtration on a

Dioscorea opposita Thunb. is widely used as functional foods and traditional Chinese medicine in China for its activity of regulating function of spleen and stomach. Polysaccharides may contribute to the function of regulation. To investigate structure features and bioactivities of polysaccharides

An association of asymptomatic hyperglycemia with dietary cyanogens and socio-economic level was ascertained in 2,000 volunteers in rural communities in South-East Nigeria. The staples of the poor consisted of one or two bulky carbohydrate meals (derivatives of different species of cocoyam, cassava,

The proximate and fatty acids compositions of dehulled African yam bean (Sphenostylis stenocarpa, Hochst ex A. Rich. Harms) flour were reported. The crude protein values ranged from 20.18 +/- 0.02 to 25.78 +/- 0.05 g/100 g; the ether extract values ranged from 1.93 +/- 0.05 to 10.18 +/- 0.04 g/100

Many plant species that are suitable for food across the world are neglected and underutilized. In order to increase their diversified food uses and thus help enhance food and nutrition security, we studied the chemical and functional properties of Pachyrhizus erosus (yam bean), which is a neglected

The proximate analysis, determination of nutritionally valuable minerals and the functional properties of the seed flour of African yam bean (AYB) (Sphenostylis stenocarpa) were investigated. Three different colour varieties of whole seeds and the dehulled samples from the same source were

African yam beans were fermented to obtain an owoh-type product. Microorganisms associated with the fermentation were Bacillus licheniformis, B. pumilus, B. subtilis and Staphylococcus sp. Total microbial counts increased from 1.53 x 10(5) cfu/g to 1.51 x 10(9) cfu/g under aerobic conditions, and

The effects of heat treatments on the proximate composition, energy content, and levels of some antinutritional factors in brown and marble-colored African yam bean (AYB) seed flours were investigated. In raw brown and marble-colored AYB seed flours; moisture content, dry matter, crude protein,

Moinmoin is a steamed cowpea seed-based pudding native to Nigeria. This study evaluated the physicochemical, proximate, and sensory properties of moinmoin from a blend of cowpea and water yam flours. The pudding was prepared by varying the proportion of cowpea to water yam flour (CWYP). The blends
