• Combination of ultrasound and enzymatic method improved extraction yield of pecans protein. • Ultrasound-assisted enzymatic method promote the tryptophan residues in protein to be more easily exposed to the protein surface. • Ultrasound reduce the diameter of protein particles to improve the dispersion of pecans protein. • Ultrasound-assisted enzymatic method changed the unfolding of protein and exposure of hydrophobic groups and sulfhydryl groups.

Iron deficiency is a common nutritional disorder worldwide.

The present study was conducted to explore the effects of a purified tartary buckwheat flavonoid fraction (TBF) on insulin resistance and hepatic oxidative stress in mice fed high fructose in drinking water (20%) for 8 weeks.
