| Popis: | Lignin, as one of the most abundant natural polymer compounds in wood and annual plants, has a complex chemical structure. It is fundamentally an aromatic polymer, composed of many aromatic rings with methoxyl and hydroxyl functional groups. Because of its multifunctional side groups, lignin can act as a free radical scavenger, thus acting as a natural antioxidant agent. However, extraction conditions, source species and structure affect the antioxidant activity of lignins. As a relatively safe and natural antioxidant, lignin can be used in foods, pharmaceuticals, cosmetics, and industrial materials. In this chapter, the correlation of lignin between structural characteristics and its radical scavenging capabilities, the relationship between antioxidant capacity and potential cytotoxicity, and the advances in commercial applications of lignin as an antioxidant were reviewed and analyzed. |
