Abstract
Functional foaming food ingredients play a vital role in preparing healthcare foods, however, the weak foamability and low photostability of ingredients severely limit their further development. Herein, whey protein isolate-resveratrol complexes (WPI-RES) were fabricated to address these challenges. Multi-spectral analysis and molecular simulation results revealed the key driving forces of hydrogen bonding and hydrophobic interactions to promote the formation of WPI-RES complexes, leading to the enhanced foamability and emulsifying properties of WPI after binding with RES. Importantly, the robust radical scavenging activity of RES within WPI was maintained under UV light irradiation compared to that of free RES as identified by DPPH assay, which was presumably due to inhibited photoisomerization of RES after binding to WPI. This work provides a promising foaming ingredient with increased ultraviolet stability and radical scavenging activity, paves the way to develop stable health-promoting foaming food products.
