Bioactive potential of a grape stem blend: a sustainable approach to skin regen...

The 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...

Development of cytisus flower extracts with antioxidant and anti-inflammatory p...

Plant flowers are recognized as a rich source of bioactive phenolic compounds. In this study, for the first time, the recovery of antioxidant phenolic compounds from Cytisus striatus flowers (CF) was optimized using microwave-assisted extraction (MAE). The variables (% of ethanol, temperature, and time) were studied using a response surface methodology (RSM). Extraction efficiency was assessed by total phenol c...

Grape stems as sources of tryptophan and selenium: functional properties and an...

The Douro Demarcated Region's winery industry produces million tonnes of by-products annually, making their reuse essential to minimize environmental impact. Grape stems, rich in bioactive compounds and nutrients, have demonstrated potential health benefits. This study analysed four red grape stems from the Douro region to assess their nutritional value and potential health benefit. Tryptophan, selenium, and ph...

Characterizing the phenolic composition and exploring the antioxidant, anti-can...

Natural products and their derivatives have played important roles in various fields, including nutrition, medicine and cosmetics. In this study, different formulated plant infusions, namely Purifying Body (PB), Boost Training (BT), Calm Night I Spirit (CN), and Boost Energy (BE) were analyzed regarding their phenolic composition and biological properties such as antioxidant, anti-inflammatory, and its influenc...

Stable and functional cosmetic creams enriched with grape stem extract: a susta...

The 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...

Microwave-assisted extraction of raspberry pomace phenolic compounds, and their...

Raspberry pomace (RBP) is rich in phenolic compounds. This study aims to optimize the extraction of phenolics from RBP and assess their bioaccessibility and bioactivity. The extraction process revealed that ethanol 50% was the most effective solvent. Microwave-assisted hydroethanolic extraction (MAE) significantly outperformed conventional methods, with optimal conditions of 200°C for 10min yielding the highest...

Phytochemical and biotechnological valorisation of winery by-products for prost...

Extraction of phenolic compounds from grape pomace using ohmic heating: Chemica...

This study addresses the effectiveness of ohmic heating technology (OH) for the sustainable recovery of phenolic compounds from Grape Pomace (GP) by hydroethanolic extraction. GP extracts biological potential was evaluated in terms of antioxidant activity, cytotoxicity and preventive effect against reactive oxygen species (ROS). To understand if GP extracts can be used as a functional ingredient, simulated gast...

Physicochemical properties of a bioactive polysaccharide film from cassia grand...

(1) Background: Polysaccharide films are promising vehicles for the delivery of bioactive agents such as collagenases, as they provide controlled release at the wound site, facilitating tissue regeneration. This study aimed to investigate the physicochemical properties of Cassia grandis polysaccharide films with immobilized collagenase from Streptomyces parvulus (DPUA/1573). (2) Methods: Galactomannan was extra...

Exploration of polyphenols extracted from cytisus plants and their potential ap...

The increasing world population means an increased demand for sustainable processes and products related to foods, particularly those with added health benefits. Plants can be an alternative source of nutritional and biofunctional ingredients. Cytisus plants are an underexploited bioresource, currently prevalent in the Mediterranean Basin and western Asia. This manuscript addresses the processing potential of C...
