Orange Biomass Lignin and Hesperidin for the Synthesis of Lignin-Based Nanoparticles as Promising Photoprotective Agents Against UV Radiation

Short Introductive summary

Orange biomass is generated in high amounts every year in Brazil because more than 50% of all of the produced oranges are processed into juice. This biomass represents a source of high added-value compounds amongst which hesperidin and lignin stand out due to a variety of benefits to human health and applications. For example, hesperidin is a flavonoid that belongs to the flavanone class and has properties like anticarcinogenic, antioxidant, and photoprotective. Lignin is an aromatic macromolecule composed of phenylpropanoid-derived units, and has the property of sun protection, due to the structure features. However, these compounds can not be used directly depending on the application, since many of their properties need to be improved. In topic applications, for example, the particle sizes need to be low for better skin absorption. There are a lot of scientific works about the use of lignin as a photoprotective agent, both in its natural form and in its nanoparticle form. In this regard, we aimed to produce lignin nanoparticles (Np_Lig), and hesperidin-loaded lignin nanoparticles (Np_LigHsd), by using the compounds extracted from orange biomass.
