Development of Inclusion Complexes With Relative Humidity Responsive Capacity as Novel Antifungal Agents for Active Food Packaging.

Allyl isothiocyanate is an excellent antimicrobial compound that has been applied in the development of active food packaging materials in the last years. However, the high volatility of this compound could prevent a lasting effect over time. In order to avoid this problem, cyclodextrin inclusion complexes have been proposed as an alternative, being beta-cyclodextrin (β-CD) as the main candidate.

Antifungal and physicochemical properties of inclusion complexes based on β-cyclodextrin and essential oil derivatives.

Inclusion complexes based on β-cyclodextrin (β-CD) and antimicrobial compounds, were prepared by co-precipitation method, and characterized by entrapment efficiency (EE), thermal analysis, X-ray diffraction, H NMR spectroscopy, and water sorption. In addition, experiments associated to evaluate the effect of relative humidity on the release of active compounds and antifungal tests were performed. The analysis evidenced the encapsulation of active compounds into the β-CD structure with EE of 91 ± 4.

An assessment of lactobiopolymer-montmorillonite composites for dip coating applications on fresh strawberries.

Background: The use of biopolymer coatings appears as a good alternative to preserve highly perishable fruits, as well as the environment. Proteins generally produce films with good mechanical properties, although their highly hydrophilic nature limits the use in many applications. Nanoparticles, such as nanoclays, can play a critical role in improving barrier properties.

Characterization of beta-cyclodextrin inclusion complexes containing an essential oil component.

An important issue in food technology is that antimicrobial compounds can be used for various applications, such as the development of antimicrobial active packaging materials. Yet most antimicrobial compounds are volatile and require protection. In the present study, the inclusion complexes of 2-nonanone (2-NN) with β-cyclodextrin (β-CD), were prepared by a co-precipitation method.
