Summary
Propolis is a natural product that meets the requirements as functional additive for food packaging due to its antioxidant and antimicrobial activities. In this work, ethanolic propolis extract (EPE) was incorporated in cassava starch films, and characterisations with respect to their microstructure, mechanical properties, water vapour permeability (WVP), moisture sorption kinetics as well as antimicrobial and antioxidant capacities were performed. The results showed that tensile strength was not affected (P > 0.05) by the presence of EPE but Young's modulus decreased about 50% when compared to control films possibly because of EPE plasticiser effect. When 1% EPE was used, changes in moisture sorption properties were detected by a slightly hydrophobic character at films WVP. When extracted from the films, propolis retained its antioxidant activity. The films exhibited antimicrobial activity against Staphylococcus aureus and Escherichia coli even at low EPE concentrations (0.5%) mainly due to its phenolic compounds.read more

Colorimetry of Total Phenolics with Phosphomolybdic-Phosphotungstic Acid Reagents
TL;DR: In this paper, the use of Folin-Ciocalteu reagent rather than the FolinDenis reagent, gallic acid as a reference standard, and a more reproducible time-temperature color development period was investigated.

TL;DR: As a general rule the ethanol extracts of plants belonging to the Verbenaceae family showed lower EC50 values than the other plant extracts, among the partitions, the more polar ones (ethyl acetate and n‐butanol) are those that generally have higher antioxidant activity (AA).

Polymeric materials with antimicrobial activity
TL;DR: The state of the art in the field of antimicrobial polymeric systems during the last decade is described in this paper, where a classification of the different materials is carried out dividing basically those synthetic polymers that exhibit antimicrobial activity by themselves; those whose biocidal activity is conferred through their chemical modification; those that incorporate antimicrobial organic compounds with either low or high molecular weight; and those that involve the addition of active inorganic systems.
