  • Title: Modification of quinoa flour functionality using ultrasound.
    Author: Zhu F, Li H.
    Journal: Ultrason Sonochem; 2019 Apr; 52():305-310. PubMed ID: 30559081.
    Abstract:
    Ultrasound has potential to modify physicochemical properties of food systems. Quinoa (Chenopodium quinoa) has become more popular due to the attractive nutritional quality. Whole grain quinoa flour was treated by ultrasound (20 kHz, 250 W) to different time length (up to 19 h). The treatment for more than 5 h significantly increased the water solubility and in vitro starch digestibility of quinoa flour, while decreasing the gelatinization temperatures and enthalpy change, viscosity during pasting event, gelling capacity, in vitro antioxidant activity, and total phenolic content. These changes were seen to depend mostly on treatment time, and indicated degradation and modifications of the chemical components (starch in particular) of quinoa flour. This study suggests the potential of ultrasound as a non-thermal processing tool to modify grain flour functionality.
