Phenolic composition and antioxidant activity of sweetpotatoes [Ipomoea batatas (L.) Lam]
… total phenolics and individual phenolic acids in sweetpotatoes. Quantification of total phenolic content using Folin-Denis reagent provided more reliable results than Folin-Ciocalteu reagent. Individual phenolic acids were quantified by reversed-phase high performance liquid chromatography (HPLC) …

The effect of controlled atmospheres on the keeping quality of sweetpotatoes
… either an alcoholic flavor or an off-flavor. Sweetpotatoes under an atmosphere of 3 percent carbon dioxide and 7 percent oxygen (3-7) had better quality than check lots as evaluated by low total losses due to decay and weight loss, higher dry matter content and a low dry matter loss, high …

Factors affecting susceptibility to - and management of - postharvest soft rot of sweetpotatoes caused by Rhizopus stolonifer.
… growing conditions and postharvest handling of sweetpotatoes. Additional studies were also completed to identify effective decay control products. A three-year study investigated the effect of preharvest conditions on R. stolonifer and Erwinia chrysanthemi susceptibility. Roots were harvested …

Effect of cultivar, storage, cooking method and tissue type on the ascorbic acid, thiamin, riboflavin and vitamin B6 content of sweetpotato [Ipomoea batatas (L.)] Lam
… thiamin and riboflavin in sweetpotato. Curing of sweetpotatoes did not significantly change the content of AA, thiamin, and vitamin B6, but resulted in a decrease in riboflavin content. Thiamin and riboflavin contents were mostly stable after curing. However, compared to at harvest, storage for 6 …

Effects of Grower Management Practices and Field Characteristics on Insect Damage to Sweetpotato (Ipomoea batatas (L. Lam.) Roots.
… growers provided thirteen field locations where sweetpotatoes were planted early (on or before 28 May) and late (after 16 June). Roots were sampled in each of the fields at approximately 90, 105, and 120 days after each planting time, graded, and scored for insect damage. Yield was also obtained. …

Dormancy and sprout control in root and tuber crops
… could be a practical sprout control method for sweetpotatoes stored at >15° C. 5 ppm or greater ethylene increased root respiration rates, but this effect was reduced by 1-MCP or AVG. Sugar content in ethylene treated roots +/- 1-MCP or AVG were lower than untreated roots, with lowest levels in …

Effects of Crop Rotation on Wireworm (Coleoptera: Elateridae) Populations in North Carolina Sweetpotato Fields
… field survey continued into early autumn. Sweetpotatoes were planted in each field used in these studies, and data were analyzed to examine wireworm populations in sweetpotato through the growing season, whether wireworm abundance differed during the growing season or by previous crop, and …
