Bioactive potential of a grape stem blend: a sustainable approach to skin regen...
Serra, Mónica; Botelho, C. M.; Sousa, Diana F.; Almeida, Hugo; Casas, Ana; Teixeira, J. A.; Barros, Ana NovoThe European wine industry is embracing sustainability through circular economy principles, particularly by valorizing by-products, such as grape stems. Grape stems are rich in phenolic compounds with recognized health benefits. This study investigates the bioactive potential of molecules extracted from a blend of grape stems (GS blend extract). The GS blend extract was chemically characterized in terms of tota...
Stable and functional cosmetic creams enriched with grape stem extract: a susta...
Serra, Mónica; Botelho, C. M.; Almeida, Hugo; Casas, Ana; Teixeira, J. A.; Barros, Ana NovoThe growing demand for sustainable and effective cosmetic ingredients has prompted renewed interest in winemaking by-products. Among these, grape stem (GS) extract remains relatively underexplored despite its rich content of phenolic compounds distinct from those found in more commonly studied grape seeds or skins. This study validates the potential of GS extract as a novel bioactive component in cosmetic cream...
Polyglutamate: unleashing the versatility of a biopolymer for cosmetic industry...
Serra, Mónica; Gudiña, Eduardo José; Botelho, Cláudia; Teixeira, J. A.; Barros, Ana NovoPolyglutamic acid (PGA), a biopolymer comprising repeating units of glutamic acid, has garnered significant attention owing to its versatile applications. In recent years, microbial production processes have emerged as promising methods for the large-scale synthesis of PGA, offering advantages such as sustainability, efficiency, and tailored molecular properties. Beyond its industrial applications, PGA exhibits...
Revealing the beauty potential of grape stems: harnessing phenolic compounds fo...
Serra, Mónica; Casas, Ana; Teixeira, J. A.; Barros, Ana NovoGrape stems have emerged as a promising natural ingredient in the cosmetics industry due to their abundance of phenolic compounds, known for their antioxidant and anti-inflammatory properties. These compounds have shown great potential in promoting skin health, fighting signs of aging, and shielding against environmental stressors. With high concentrations of resveratrol, flavonoids, and tannins, grape stems ha...
Microbial hyaluronic acid production: a review
Serra, Mónica; Casas, Ana; Toubarro, Duarte; Barros, Ana Novo; Teixeira, J. A.Microbial production of hyaluronic acid (HA) is an area of research that has been gaining attention in recent years due to the increasing demand for this biopolymer for several industrial applications. Hyaluronic acid is a linear, non-sulfated glycosaminoglycan that is widely distributed in nature and is mainly composed of repeating units of N-acetylglucosamine and glucuronic acid. It has a wide and unique rang...
Avaliação nutricional e qualidade de vida em idosos institucionalizados e não-i...
Henriques, Ana Rita; Serra, MónicaO número de idosos institucionalizados em Portugal tem vindo a aumentar. O envelhecimento acarreta diversas alterações, podendo estas comprometer a qualidade de vida, a alimentação do idoso e, consequentemente, o seu estado nutricional. Verificar se a qualidade de vida está relacionada com o estado nutricional de idosos institucionalizados e não institucionalizados. Estudo observacional analítico transversal, c...
