New Insights into pH-dependent Complex Formation between Lignosulfonates and An...
Pereira, AR; Bravo, C; Ramos, RM; Carina Costa; Rodrigues, A; de Freitas, V; Mateus, N; Dias, R; Soares, S; Joana OliveiraAnthocyanins have limited application as natural colorants and antioxidants due to their color loss and instability under certain conditions. This research explores the formation of a complex between lignosulfonates (LS) and cyanidin-3-O-glucoside (C3G) using a multitechnique approach as well as the effect on C3G ' s red color, oxidative stability, and antioxidant activity in acidic mediums. All data revealed p...
First Insight into Lignin Valorization as a Promising Biopolymer for the Modula...
Pereira, AR; Brandao, E; Pinto, J; de Pinho, PG; Carina Costa; Rodrigues, AE; Michelin, M; Soares, S; de Freitas, V; Mateus, N; Oliveira, JLignosulfonate (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...
Exploring the Potential of Vine Shoots as a Source of Valuable Extracts and Sta...
Pereira, AR; Carina Costa; Nuno Mateus; Victor de Freitas; Rodrigues, A; Joana OliveiraLarge amounts of vine shoots are generated every year during vine pruning. This residue still presents many of the compounds found in the original plant, including low molecular weight phenolic compounds and structural compounds such as cellulose, hemicellulose, and lignin. For wine-producing regions, the challenge is to develop alternatives that will increase the value of this residue. This work proposes the f...
Dietary Interventions to Prevent Childhood Obesity: A Literature Review
Pereira, AR; Oliveira, ASeveral dietary interventions have been conducted to prevent/reduce childhood obesity, but most of them are known to have failed in tackling the obesity epidemic. This study aimed to review the existing literature on dietary interventions for the prevention of childhood obesity and their effectiveness. A literature search was conducted using PubMed Central®. Only articles published between 2009 and 2021, writte...
