First insight into lignin valorization as a promising biopolymer for the modula...
Pereira, Ana Rita; Brandão, Elsa; Pinto, Joana; Pinho, Paula Guedes de; Costa, Carina A. E.; Rodrigues, Alírio E.; Michelin, Michele; Soares, SusanaLignosulfonate (LS), kraft lignin (KL), and organosolv lignin (OL) were evaluated as potential modulating agents of the physicochemical properties of Port wine at two different concentrations for 7 and 30 days. KL and LS demonstrated the ability to remove proteins and potentiate the anthocyanin concentration. LS reduced the tannin content and the interaction of salivary acidic proline-rich proteins with wine ph...
Sugarcane light-colored lignin: a renewable resource for sustainable beauty
Mota, Inês F.; Antunes, Filipa; Fangueiro, Joana F.; Costa, Carina A. E.; Rodrigues, Alírio E.; Pintado, Manuela E.; Costa, Patrícia S.Lignin has emerged as a promising eco-friendly multifunctional ingredient for cosmetic applications, due to its ability to protect against ultraviolet radiation and its antioxidant and antimicrobial properties. However, its typical dark color and low water solubility limit its application in cosmetics. This study presents a simple process for obtaining light-colored lignin (LCLig) from sugarcane bagasse (SCB) a...
Influence of soil copper content on the kinetics of thiram adsorption and on th...
Filipe, Olga M. S.; Costa, Carina A. E.; Vidal, Maria M.; Santos, Eduarda B. H.This work aimed to assess the influence of soil copper content on the sorption processes of thiram, a fungicide widely used in agriculture, most of the times together with copper. Two different types of studies were performed: (1) desorption studies of thiram with acetonitrile after batch adsorption equilibration, and ageing of the wet soil for a variable period of time; (2) kinetic studies of thiram adsorption...
