Evidence Details
The extraction was conducted at 50 °C using both 600 W ultrasonic power and 500 W microwave power for 20 min.
UMAE resulted in the highest protein yield at 86.94%, followed by UAE (61.68%), MAE (58.74%), and AAE (56.64%).
The results demonstrate that UMAE significantly enhances the functional properties of Se-RBP, achieving an emulsion stability index of 86.76% and a foaming capacity of 188.63%.
The extraction was conducted using a microwave-ultrasound combination synthesizer (XH-300B, Beijing Xianghu Technology Development Co., Ltd.).
Furthermore, UMAE-treated Se-RBP exhibited a 35.43% increase in selenium bioavailability following gastrointestinal digestion.
UMAE also delivered the highest antioxidant activity, reducing the IC50 for DPPH radical scavenging to 0.85 mg/mL.
Average particle size: 295.17 nm
Average particle size: 281.33 nm
