Resumo
Carotenoids such as curcumin and bixin are polyisoprenoids, and are responsible for red, orange
or yellow colors. Curcumin is a yellow hydrophobic polyphenol that presents a low molecular
weight. Bixin is a natural color extracted from the Annato tree and its color varies from yellow to
red due to the presence of the isomer carotenoid trans-bixin. Food and cosmetic industries use
them due to their antioxidant properties. The biodegrading properties of polymer blends can be
improved by the addition of vegetable oil, organic and inorganic additives or by mixing them
with a biodegradable polymer. According to previous studies, polymers produced by a mixture of
Moringa polymer (PMO), polyethylene (PE) and commercial biodegradable polymers (PB),
composed of PBAT (poly(butylene adipate-co-terephthalate)/PLA (polylactic acid), presented
mechanical properties similar to those of PE, except for a higher biodegradation capacity.
Vegetable oils can be used as plasticizers for polymer blends and Moringa oil and improved the
biodegradation properties in other studies.
