Dataset on guarana–pea protein conjugates for vitamin D3 emulsions

The experimental data include the physicochemical and stability characterization of O/W emulsions produced using pea protein isolate (PPI) conjugated with guarana extract (GE) as stabilizing agents. The dataset comprises measurements of particle size distribution, microstructure, vitamin D3 retention during storage under different conditions, and in vitro bioaccessibility. The study evaluates how the combination of heat treatment and PPI–GE conjugation influences emulsion stability and vitamin D3 protection.
