As the second most abundant biopolymer on Earth, with millions of tons generated annually, lignin possesses powerful antioxidant properties due to its complex polyphenolic structure. This natural ability to neutralize free radicals is unlocking a wide range of sustainable, high-value applications for this versatile and abundant resource.

According to the Food and Agricultural Organization (FAO), 1.3 billion tons of food are wasted annually, with agri-food by-products being a rich source of polyphenols. Determining the best way to extract polyphenols from these materials is crucial for minimizing waste and creating valuable compounds for the food, cosmetic, and pharmaceutical industries.

Yes, some types of propanediol are made from corn, with a significant bio-based version like Zemea® originating from corn sugar fermentation. This provides a sustainable, eco-friendly alternative to the petroleum-based ingredients found in many personal care and cosmetic products.

The human body is unable to produce its own vitamin C (ascorbic acid), requiring it to be obtained from external sources, primarily through diet. The process of extracting this vital antioxidant varies widely, from simple kitchen-based methods using common fruits to highly complex, multi-step industrial and laboratory procedures.
