Aquafaba is a liquid residue of cooked pulses, which is generally discarded as waste. However, it is rich in proteins and, thus, can be used as a plant-based emulsifier to structure vegetable oil. This study investigates chickpea aquafaba (CA) as an agent to structure different oil phase volumes (Φ) of canola oil (CO). CO was structured in the form of conventional emulsions (EΦ65% and EΦ70%) and high internal phase emulsion (HIPE) (EΦ75%) by the one-pot homogenization method. Emulsions were evaluated for a period of 60 days at 25 °C in terms of average droplet size (11.0–15.9 µm), microscopy, rheological properties, and oil loss (<1.5%). All systems presented predominantly elastic behavior and high resistance to coalescence. EΦ75% was the most stable system throughout the 60 days of storage. This study developed an inexpensive and easy to prepare potential substitute for saturated and trans-fat in food products. Moreover, it showed a valuable utilization of an often-wasted by-product and its conversion into a food ingredient.

Fruit drying is a process meant to preserve fruits and to increase its shelf-life by reducing the water and enzyme activities and minimizing microbiologic contamination of the product (Paes et al., 2019). Recent studies on fruit drying have evaluated new drying technologies aiming higher product quality and lower cost (Magalhães

Effects of acid modification on the physicochemical, rheological, microstructural and expansion on cassava starch with lactic, acetic and citric acids in proportions of 5 %, 10 % and 15 % were investigated. This effect was verified on swelling power and solubility index, rheology, pH, scanning electron microscopy, thermal analysis and baking test. The results were available by ANOVA and Tukey test. The study indicates that the acid treatment influenced significantly the physicochemical properties. The lactic and acetic acids did not modify the rheological model of the cassava starch, but showed a reduction in the apparent viscosity. The acetic and lactic acids had a strong influence on the starch granules. Thus, the acid modification of cassava starch promotes the significant changes in starch properties.
