The effects of wheat flour substitution by sweet potato powder on rheological parameters of wheat dough and physical parameters of cookies and crackers were analyzed. Wheat flour was substituted with sweet potato powder at level 2.5%, 5%, 7.5%, and 10%. Sweet potato powder was characterized by high water holding capacity (9.00 g/g) and swelling capacity (8.16 cm/g). The addition of sweet potato powder significantly changed the rheological properties of wheat dough (water absorption and mixing tolerance index were increased, dough stability was reduced, and dough development time was prolonged). It was also found that volumes of cookies and crackers were decreased, and spread ratios were increased with the addition of sweet potato powder. Lightness of baked products decreased and yellowness increased with the addition of sweet potato powder. Incorporation of sweet potato powder significantly decreased the hardness of cookies and crackers. Sensory evaluation showed that the most acceptable cookies and crackers were the ones obtained after the addition of sweet potato powder at level 2.5% and 7.5%, respectively.

The effects of sugar boiling pretreatment (SBP) with different maltitol concentrations (20 %, 30 %, and 40 %) and boiling time (0 - 6 min) on the physicochemical and functional properties of purple sweet potato flour and the radiofrequency explosion puffing (RFEP) quality were investigated. The results showed that the volume ratio, crispness, anthocyanin retention rate and overall acceptability of the samples were maximized after boiling for 6 min at 40 % maltitol concentration achieving increases of 78.63 %, 437.

The effects of lactic acid bacteria fermentation and in vitro simulated digestion on phenolic bioavailability, phenolic bioavailability, and antioxidant activity of purple sweet potato juice (PSPJ) were investigated. The PSPJ was fermented by and . The viable bacterial count, phenolic components, antioxidant activity, phenolic bioaccessibility, and phenolic bioavailability of PSPJ were analyzed during the simulated digestion process in vitro.

This study aimed to develop tuber bread from purple sweet potato and bambara beans with high satiety and low glycemic index (GI). Different ratios of purple sweet potato to bambara bean were used: 100:0 (F0), 80:20 (F1), 60:40 (F2), and 40:60 (F3). The satiety index (SI) was determined by assessing the consumption of a 240 kcal isocaloric food and collecting data through a visual analog scale.
