Comparative Evaluation of Physico-chemical Characteristics of Flours from Steeped Tubers of White Yam (Dioscorea rotundata Poir), Water Yam (Dioscorea alata L.) and Yellow Yam (Dioscorea cayenensis Lam)
The study examined Yam Tuber Species (YTS), Tuber Steeping Duration (TSD) and Flour Particle Size (FPS) as factors of flour. Data were collected using white yam, water yam and yellow yam steeped in water (30 ± 2 °C, pH 6.78) and withdrawn, and the flour classified, and analyzed for each parameter. Results obtained showed that all the test parameters, Water Retention Capacity (WRC), Swelling Ind...
متن کاملFunctional properties of dioscorin, a soluble viscous protein from Japanese yam (Dioscorea opposita thunb.) tuber mucilage Tororo.
A soluble viscous protein was purified from yam (Dioscorea opposita Thunb.) tuber mucilage tororo by chromatographic steps, and its functional properties were estimated. The purified dioscorin having the molecular weight of about 200 kDa exhibited high scavenging activities against hydroxyl radicals (IC50 = 195.1 microg/ml) and superoxide anion radicals (IC50 = 92.7 microg/ml). Moreover, it sho...
متن کاملWithanolides from the rhizomes of Dioscorea japonica and their cytotoxicity.
Edible yams are tropical crops that serve as important staple foods in many parts of the world. The rhizome of Dioscorea japonica , well-known as "Japanese yam", is a food and medicinal source known as "San Yak" in Korea. Bioassay-guided fractionation and chemical investigation of the extract of this yam resulted in the identification of two new withanolides, named dioscorolide A (1) and diosco...
متن کاملIn vitro regeneration of Hypericum patulum Thunb.--a medicinal plant.
A protocol was developed for high frequency plant regeneration in H. patulum by shoot-tip culture. H. patulum plants were collected from a wild source growing at high altitude in the eastern Himalayas. Multiple buds were initiated from shoot-tips cultured on Murashige and Skoog's medium supplemented with BAP, kinetin. Addition of thiamin HCI, Ca-pantothenate and biotin enhanced multiple shoot f...
متن کاملMicrowave and blanch‐assisted drying of white yam (Dioscorea rotundata)
The effect of microwave and blanch pretreatments on the drying kinetics and quality of white yam (Dioscorea rotundata) was investigated. Yam cubes destined for hot air drying at temperatures 70-90°C were predried in a domestic microwave or blanched in hot water for 1-5 min. Microwave pretreatment time had a positive significant effect on drying rate but both pretreatments had a negative influen...
