Alginate edible films containing essential oils: characterization and bioactive...

Essential oils (EOs) are natural substances rich in phenolic compounds with notable antimicrobial and antioxidant properties. However, they present some limitations, such as low stability and bioavailability. Incorporating EOs into polymeric films offers a novel approach to overcome these challenges while enhancing their efficacy. In this study, we produced and thoroughly characterized alginate-based edible fil...

From waste to worth: upcycling peanut skin via green extraction for bioactive a...

Aim: The valorisation of agro-industrial by-products represents a strategic approach toward reducing food processing waste while fostering circular bioeconomy practices. Peanut skin, a by-product of peanut processing, is particularly rich in phenolic compounds with significant antioxidant and antimicrobial properties, making it a promising candidate for sustainable applications in the cosmetic and textile indus...

Alkaline extraction of phenolic compounds from Eucalyptus leaves: influence on ...

Introduction: The valorization of agro-industrial by-products is a strategic approach to reducing biomass waste while advancing circular bioeconomy practices. Eucalyptus leaves, an abundant residue from the forestry and pulp industries, are particularly rich in phenolic compounds with well-known antioxidant and antimicrobial activities. These bioactivities highlight the potential of eucalyptus extracts for sust...

Phenolic Profile and Antioxidant and Biological Activities of Plant Extracts Ri...

In this work, hydroethanolic plant extracts (acorn husk, laurel, eucalyptus, and rockrose leaves) were screened for their content in condensed tannins (HPLC-DAD/MS), polyphenol content, antioxidant, antimicrobial, and antiviral activities, and lack of toxicity. The results showed the highest values of condensed tannins found for laurel and eucalyptus extracts, while the total phenolic content ranged within 204....

Be@t: sustainable chemical processes for developing regenerative materials and ...

Introduction: The reuse and valorization of waste and by-products generated by other industrial sectors in the textile sector currently represents a strategy of 'sustainable waste minimization,' leading to the achievement of economic development and environmental sustainability goals. In recent years, waste and by-products from industrial processing, e.g., agro-industry, agroforestry, marine, canning, mining, l...

Evaluation of antimicrobial and antioxidant activities of alginate edible coati...

Plant extracts (PEs) are natural substances that perform interesting bioactivities. However, they have some limitations. In this work, PEs from licorice, eucalyptus, sage, and thyme were produced and characterized. These extracts showed good bioactive properties. Alginate-based edible coatings and films incorporated with the extracts were produced and their antimicrobial and antioxidant properties were determin...

Red grape pomace extract: bioactive potential against bacteria, fungi and SARS-...

The outbreak of COVID-19 disease caused by SARS-CoV-2 forced the scientific world to search for new alternatives to help control the virus. Grape pomace, which is an industrial residue obtained from the winemaking process, has bioactive compounds derived from the grape [1], which can be a starting point for research on the use this residue as a source of new antiviral agents. Thus, the objective of this study w...

Chemical characterization, cytotoxic evaluation and anti-SARS-CoV2 activity of ...

Evaluation of minimum inhibition concentrations of plant against environmental ...

The outbreak of COVID-19 disease eaused by SARS-CoV-2 has led the seientifie eompmnity to seareh for new alternatives to help eontrol the virus. In this context, the use of face masks has been reeommended as a preventive measure against the spread of SARS-CoV-2. The application of antimierobial agents in the tissues used to produee masks would be an additional hurdle on the prevention of other respiratory infee...
