Sweet potato ( (L.) Lam.) is a tuber root crop with high economical potential and China is responsible for harvesting roughly 70% of the world production. It is relatively easy to cultivate and has high nutritional value, including fiber, vitamins, starch and sugars. Cooking the roots results in deep changes of the carbohydrate profile due to the presence of active endogenous amylases. The objective of the present study was to evaluate the influence of CaCl mashing at different temperature-time conditions on the starch hydrolysis by endogenous amylases of sweet potato in order to suggest potential industrial applications. Three thermal treatments were performed with the aid of a Rapid Visco Analyzer (RVA), which allowed programming temperature-time profiles. After the treatments, the sugar analysis was carried out by high performance liquid chromatography (HPLC). Total starch content was measured in the insoluble residue from the hydrolysis and the hydrolysis efficiency was calculated. The results have demonstrated that the presence of CaCl enhanced enzyme activity, resulting in higher sugar yields when compared to hydrolysis conducted without CaCl. The results from the present study are promising to the use of sweet potato to produce bioethanol, maltose syrup and vinegar.

Regularly consuming orange-fleshed sweet potatoes (OFSP) is widely recognised as an effective way to treat vitamin A deficiency (VAD), particularly in low-income countries. Unfortunately, cultivars of OFSP are poorly disseminated in most countries in sub-Saharan Africa, where VAD is a major cause of blindness. This study was conducted to evaluate the effect of the genotype-environment interaction (GEI) on the performance and stability of the yield components of OFSP cultivars to trigger their adoption by farmers.

This study proposes the use of lyophilized powder of purple-fleshed sweet potato (LP) as a new multifunctional ingredient to improve the identity and quality parameters of stirred yogurts. The physical and chemical properties, color, monomeric anthocyanin content, lactic acid bacteria viability, water retention capacity, microstructure, and texture were evaluated for yogurts enriched with LP at the levels of 2% (YLP2), 4% (YLP4), and 6% (YPL6), stored for 30 days under refrigeration (4 °C). The results indicated that LP provided different intensities and shades of pink coloration to yogurt, in addition to increasing ( < 0.

Recent studies have focused on the generation of biomaterials from natural sources, highlighting the use of starch from different sources to obtain edible films and coatings. In this study, edible films were developed from sweet potato starch, and their potential use in candy packaging was evaluated. Films were prepared by the casting method, and the effects of sweet potato starch (3 %-5 % w/w), glycerol (0.

In this work, the functional activities including α-glucosidase, α-amylase, angiotensin converting enzyme (ACE) inhibitory activity, and antioxidant activity of mixed grains (mung beans, cowpeas, and quinoa) fermented with Bacillus amyloliquefaciens SY07 were investigated. The volatile flavor of the mixed grains collected every 12 h during 72 h-fermentation were further detected as well. The inhibition on α-glucosidase and α-amylase reached up to 89.
