pH-shifting and high-intensity ultrasound enable the functional design of quinoa protein isolate as a plant-based emulsifier.
Quinoa protein isolate (QPI) derived from dehulling by-products was structurally tailored using a combined pH-shifting and high-intensity ultrasound (HIU) approach to enhance its functionality as a plant-based emulsifier. Alkaline conditions (pH 11) promoted protein unfolding, increasing solubility, surface charge, and...
