Bioactive Properties of Microencapsulated Anthocyanins from and .

Anthocyanins, widely recognized for their antioxidant properties and potential health benefits, are highly susceptible to degradation due to environmental factors such as light, temperature, and pH leading to reduced bioavailability and efficacy. Microencapsulation, which involves entrapment in a matrix to enhance stability and bioavailability. This study aims to investigate the bioactive properties of microencapsulated anthocyanins derived from (Andean blueberry) and (Andean blackberry).

Microencapsulation of Anthocyanins from and : Impacts on Antioxidant, Antimicrobial, and Cytotoxic Activities.

This study investigates the biological activities of microencapsulated anthocyanins extracted from two Andean ancestral edible plants, , and , with a focus on their potential applications in functional foods and therapeutics. The primary objective was to evaluate their antioxidant, antimicrobial, and cytotoxic properties alongside structural and functional analyses of the microencapsulation process. Anthocyanins were extracted and microencapsulated using maltodextrin as a carrier.

Spray Drying of Chitosan Acid Salts: Process Development, Scaling Up and Physicochemical Material Characterization.

We investigated a spray drying process for preparing water-soluble salts of high molecular weight chitosan (CH) intended for pharmaceutical excipient applications. CH was derived from chitin of marine lobster origin (). The effects of organic acid (acetic or lactic acid) and the ratio (difference) of inlet/outlet air temperature (140/90 °C or 160/100 °C) on spray drying were studied.

Effects of spray drying on physicochemical properties of chitosan acid salts.

The effects of spray-drying process and acidic solvent system on physicochemical properties of chitosan salts were investigated. Chitosan used in spray dryings was obtained by deacetylation of chitin from lobster (Panulirus argus) origin. The chitosan acid salts were prepared in a laboratory-scale spray drier, and organic acetic acid, lactic acid, and citric acid were used as solvents in the process.
