In this project, we evaluated the antioxidant properties and sun protection factor (SPF) of LDH composites with natural components from tomato. The results indicated that the 11 % of organic matter content in the composites is sufficient to increase their antioxidant properties, such as higher antioxidant activity towards ABTS·+ than towards DPPH·. The composite also improves degradation in oxygen atmosphere detected in the Rapidoxy assay, while the SPF indicated that the LDH particles play a crucial role as sunscreen rather than the organic content. This study found that the composite formed by lycopene and LDH particles enhances the hydro-dispersibility and improved the antioxidant stability of lycopene which are key properties to develop cosmetics or food ingredients.Show less >
