Tanshinone compounds, natural antioxidants found in the roots of Salvia subg Perovskia plants, offer various health benefits and can serve as natural food additives, replacing synthetic antioxidants. In this study, the nanoparticles were created using the antisolvent method, which were then evaluated for their antioxidant and antibacterial properties, as well as their ability to release tanshinone and withstand environmental stress. The results of the study demonstrated a significant improvement in the antioxidant capabilities of tanshinone with the nanoparticle coating. The T/Z/P NPs exhibited enhanced tanshinone release under simulated gastrointestinal conditions compared to T/Z nanoparticles. These nanoparticles displayed remarkable stability against fluctuations in environmental pH and thermal conditions. The study also revealed that the critical flocculation concentration of the system was 0.5 M of salt. Furthermore, the T/Z/P NPs showed good stability during storage at 4°C for 30 days, making them an excellent candidate for use in various food products. •Encapsulating tanshinone in T/Z/P NPs enhanced its antioxidant capability notably.•The T/Z/P NPs exhibited superior tanshinone release under SGF and SIF conditions.•CFC of the system was determined to be 0.5 M of salt.•T/Z/P NPs exhibited remarkable stability against thermal conditions.•T/Z/P NPs exhibited acceptable stability during storage at 4 °C for 30 days.
