Due to the growing concern about the environmental footprint of plastics, one of the key trends in modern polymer science is the development of materials that not only possess useful properties but also have inherent (bio)degradability and/or are derived from renewable resources.

Xanthophylls are oxygenated derivatives of carotenoids and, as natural biologically active compounds with known pharmacological properties, they have many positive effects on human health. For some esterified xanthophylls it was shown that they have superior stability and bioavailability compared to their free form. We have developed an energy-efficient and environmentally friendly synthetic platform for the preparation of a variety of xanthophyll esters. This platform can be applied to pigments in pure form (eg., lutein, zeaxanthin, β-cryptoxanthin, capsanthin, violaxanthin), but extracts…

The invention is biodegradable chitosan-based foil, which is enriched with a potent antioxidant plant extract, obtained from an invasive plant species, Japanese knotweed (Polygonum cuspidatum, Fallopia japonica Houtt.), which due to its fast expansion poses global ecological damage, displaces autochthonous plants and leads to a reduction in biodiversity. Moreover, it is causing huge economic harm (e.g. damage to infrastructure).
