Unveiling the Potential of Southern Elderberry (Sambucus australis): Characterization of Physicochemical Properties, Carbohydrates, Organic Acids and Biophenols.

Sambucus australis is a wild species with purple fruits like berries. It is native from South America and can be found in Argentina, Uruguay, Paraguay, Bolivia, and Brazil. A comprehensive characterization of S.

Effects of the geometry of reinforcement on physical properties of sodium caseinate/TiO nanocomposite films for applications in food packaging.

Plastic materials for food packaging are being replaced by biodegradable films based on biopolymers due to the adverse effects they have had on animal life and the environment. In this study, nanocomposite films containing 2.5 wt% sodium caseinate and 2 wt% glycerol were reinforced with 0.

Protein recovery from brewery solid wastes.

Brewing produces significant amounts of solid waste during the process: spent cereals (BSG), hops and spent yeast (BSY). These residues are sustainable sources of valuable nutrients and functional compounds like proteins, polyphenols, and polysaccharides. This review describes the three solid wastes and the different extraction techniques for protein recovery.

Nanoreinforcement as a strategy to improve physical properties of biodegradable composite films based on biopolymers.

Food packaging is evolving from inert plastic to renewable biopolymer film that acts as barrier against gases, light radiation, and microorganisms, reducing food waste without environmental damage. Distinct starting systems were selected to prepare films: single polymer matrix, blend of polymers, cross-linked polymers, and emulsion-based matrix. The blend of polymers was one of the best approaches to improve mechanical and barrier properties of films, especially when one of the polymers was pectin, gelatin or xanthan gum.

Changes in physicochemical properties at different development stages of fruit, an underutilized South American species.

The aim of this work was to study the evolution of fruit size and weight together with the soluble solid and total titratable acidity contents during development of fruit. Also, the patterns of accumulation of chlorophylls, carotenoids, phenols and antioxidant activity were analysed to define the optimal time for harvesting to obtain maximum nutraceutical characteristics. Fruits were harvested from plants growing at the experimental field of the University of Morón (Moreno, Buenos Aires, 34°35'4.
