Prebiotic effects of olive pomace powders in the gut: In vitro evaluation of th...

Olive pomace is a biowaste rich in polyphenols and insoluble dietary fibre with high potential to develop new value chains towards a sustainable and circular bioeconomy. Regarding gut health, olive pomace phenolics and insoluble dietary fibre (after possible fermentation) could act as antioxidants, antimicrobial and prebiotic agents. These potential beneficial effects on the gut were analysed for two powders fr...

Textile dyes loaded chitosan nanoparticles: characterization, biocompatibility ...

Textile dyeing is a hazardous and toxic process. While traditionally it has been managed through effluent treatment, new approaches focused upon improving the dyeing process are gaining relevance. In this work, we sought to obtain, for the first time, an eco-friendly chitosan-nanoparticle based textile dyeing method. To that end, yellow everzol and navy blue itosperse loaded chitosan nanoparticles were produced...

Are olive pomace powders a safe source of bioactives and nutrients?

BACKGROUND Olive oil industry generates significant amounts of semi-solid wastes, namely the olive pomace. Olive pomace is a by-product rich in high-value compounds (e.g. dietary fibre, unsaturated fatty acids, polyphenols) widely explored to obtain new food ingredients. However, conventional extraction methods frequently use organic solvents, while novel eco-friendly techniques have high operational costs. The...

Potential prebiotic effect of fruit and vegetable byproducts flour using in vit...

Fruit and vegetable byproducts (FVBP) present high content of bioactive compounds and dietary fibers and have demonstrated a positive modulatory effect upon gut microbiota composition. In the present study, the prebiotic potential of a FVBP flour obtained from solid byproducts after fruit and vegetable processing was evaluated after in vitro gastrointestinal digestion. An initial screening with three strains of...

Impact of plant extracts upon human health: a review

With the increase in evidences directly linking diet and health, several foodstuffs, such as phenolic rich fruits and vegetables, have emerged as possessing potential health benefits. Plants, given their fiber and phenolic content (and their intrinsic biological potential), have long been considered as contributing to health promotion. Therefore, the present work aimed to review the existing evidences regarding...

Health promoting properties of blueberries: a review

With the strengthening of the link between diet and health, several foodstuffs have emerged as possessing potential health benefits such as phenolic rich fruits and vegetables. Blueberries, along with other berries, given their flavonoid and antioxidant content have long since been considered as a particularly interesting health promoting fruit. Therefore, the present work aimed to compile the existing evidence...
