Antioxidant profile of Portuguese and Spanish craft beers

Background: The antioxidant potential of craft beer (CB) may be due to high quality of the raw materials (water, malt, hop and yeast) and traditional techniques [1-4]. The scarcity of studies evaluating the antioxidant potential of CB highlights the relevance of this study. Objective: In vitro evaluation of the antioxidant activity of aqueous extracts of Portuguese and Spanish CB. Methods: Experimental study us...

Potential impact of packaging type material in beer quality

Background: The materials in which beverages are packed are crucial to maintain quality, nutritional properties, and safety of the final product. In what beer concerns, and even under optimal storage conditions, its quality deteriorates as the product approaches the expiration date, regardless of the container type in which it is packed [1]. Therefore, a careful selection of packaging is imperative to maintain ...

Atividade antioxidante de extratos da alga Undaria pinnatifida (Wakame)

O consumo de algas marinhas aumentou nos últimos anos, sendo consideradas importantes fontes alimentares. As algas possuem compostos bioativos, incluindo polissacáridos sulfatados (fucoidano), polifenóis (florotaninos), e pigmentos naturais (fucoxantina). Um exemplo de alga castanha cultivada é a Undaria pinnatifida, conhecida como “Wakame” no Japão, e considerada uma das piores espécies invasoras do mundo. As ...

Development of quercetin-loaded polymeric nanoparticles for topical application

Quercetin, a phenolic compound, has been attracting a growing interest from the scientific community due to its health benefits (i.e. antioxidant, anti-inflammatory, and cardiovascular protection), and may become useful in the prevention and/or treatment of several diseases. Nevertheless, its pharmaceutical industry application is limited, due to its physicochemical characteristics, such as bioavailability. How...

Optimization of an HPLC-DAD method for Quercetin detection

High-performance liquid chromatography (HPLC) is one of the most used liquid chromatographic techniques owing to its versatility that allows an optimal resolution. Quercetin (QUE), a polyphenol, has received increasing attention due to its antioxidant properties. Efforts have been made to overcome the traditional poor oral bioavailability of quercetin, requiring the development of analytical techniques for quer...
