Solvent-driven extraction of bioactive compounds from propolis for application ...

Propolis is a resinous substance collected by honeybees from plant exudates and enriched with beeswax, pollen, and enzymes. Known for its antioxidant, antimicrobial, and anti-aging properties, it has attracted interest for applications in food, nutraceutical, and cosmetic industries. In this work, Portuguese propolis from the Guarda region was characterized to evaluate how different solvents influence extractio...

Cascading recovery of added-value cocoa bean shell fractions through autohydrol...

In this work, an autohydrolysis treatment was applied to cocoa bean shells (CBS) to obtain different potentially added-value fractions rich in phenolic compounds with antioxidant potential and oligosaccharides with potential prebiotic properties. The final residue was enzymatically treated to deliver sugars that can undergo fermentation-based biotransformation. This hydrothermal pretreatment was assessed for ma...

Protein fractions from seaweeds: evaluating fractionation techniques to improve...

From grape pomace to valuable products: sequential fractionation using ohmic he...

[Excerpt] Conclusions The sequential OH-SWH fractionation of GP shown as promising strategy for its integral valorisation, and the resulting products could have potential applications in human nutrition, cosmetics and biopolymers production. Nevertheless, more research need to be performed in order to optimize extraction conditions, produce the new valuable products and achieve the zero waste biorefinery cascad...

C-Phycocyanin as a natural alternative to the synthetic blue food dye E133 in b...

[Excerpt] E133 is a synthetic blue dye derived from petroleum, commonly used in processed foods and drinks. Replacing it with a natural alternative would be a step towards eliminating synthetic additives and preservatives in food products.

Innovation on vegan ham analogues using new protein sources

[Excerpt] Introduction The challenges in food production, driven by environmental and health concerns, are leading to a shift in consumer preferences towards alternative and more sustainable protein sources. The market for vegetarian and vegan meat alternatives is growing, yet market acceptance poses a challenge when talking about the appearance and sensory qualities of these formulations, as they differ greatl...

Microalgae extracts reduce appetite in zebrafish larvae linked to long-chain fa...

Appetite modulation is a promising strategy for obesity treatment. The presented research screened 103 microalgae extracts from three strains of microalgae (Chlorella sp., Chlorococcum sp. and Nannochloropsis oceanica) for appetite reducing activity, using high pressure processing and moderate electric fields. Two different feeding assays with zebrafish larvae were applied using either fluorescent labeled lipos...

Aqueous extracts of Moringa oleifera and Cinnamomum cassia as promising sources...

Bacterial biofilms formed by Staphylococcus aureus and Pseudomonas aeruginosa pose significant challenges in treating cystic fibrosis (CF) airway infections due to their resistance to antibiotics. New therapeutic approaches are urgently needed to treat these chronic infections. This study aimed to investigate the antibiofilm potential of various plant extracts, specifically targeting mucoid and small colony var...

Advancing 3D-printed seafood analogues with Tetraselmis chui and Tetraselmis ch...

The urgent need for sustainable agrifood practices has driven the exploration of alternative protein sources. This study investigates the potential of Tetraselmis chui and its extract as ingredients in 3D-printed seafood analogues. The rheological, textural, and color properties of Tetraselmis chui and Tetraselmis chuis extract were compared with pea protein. The results demonstrated that Tetraselmis chui and T...

Advancements in ulvan valorization from Ulva rigida: unveiling a combined appro...

Ulvan is the sulphated polysaccharide present in the cell wall of the green seaweed Ulva sp., exhibiting some rheological and biological features. The traditional recovery of this polysaccharide has certain drawbacks, including high energy and time consumption and the use of chemicals generating dangerous residues in the environment. Green alternative processing technologies have drawn attention due to their sh...
