Special Issue Information

Dear Colleagues,

The importance of designing new materials supported by bio-based polymers or their derivatives, and with bioactivity imparted by natural functional ingredients, is progressively gaining relevance. This requires the combination of sustainable strategies for coatings preparation, and the effective use of the renewable entities and additives to concurrently satisfy the specific requirements of potential applications. Among others, it is worth noting the importance of coatings holding bioactivity (e.g., antioxidant, antimicrobial, anti-inflammatory, or immune system stimulation capacity) for applications such as food, cosmetics, sanitization/disinfection, biomedical, etc. Diverse strategies can be used for this purpose, from the anchoring of functionalities to the modification of natural polymers holding intrinsic bioactivity, and the incorporation of natural functional ingredients able to provide functional attributes to the base coating. Moreover, the processing method selected for the coating’s preparation (casting, electrospinning, spraying, layer-by-layer, etc.) offer a broad range of possibilities in terms of formulations application.

Therefore, this Special Issue aims to give an overview of the most recent trends in the field of bio-based bioactive coatings, aided by your expertise in the area. We welcome the contribution of your latest works covering topics from the modification of natural polymers, the incorporation of bioactive compounds, or green coatings preparation methods to their characterization and applicability evaluation in concrete applications.

In particular, the topics of interest include but are not limited to:

  • Sustainable bio-based coatings;
  • Coatings preparation through green chemistry strategies;
  • Coatings processing methods;
  • Coatings with added natural functional ingredients;
  • Coatings with antimicrobial properties;
  • Coatings holding bioactive/functional properties;
  • Applications of bio-based coatings.

Mango is a highly preferred seasonal tropical fruit with a maximum shelf-life of five to seven days. Hexanal is a plant volatile compound assayed in green tissues and showing significance in enhancing storage life and fruit quality attributes by preserving membrane integrity. This experiment explored the effect of the pre-harvest application of an aqueous hexanal composition (active ingredient: 0.02% hexanal) in altering the post-harvest storage behavior of four mango cultivars. The pre-harvest application of the hexanal formulation to the fruit surface twice before the harvest date drastically slowed down the physiological loss in weight by 70% to 80%, and reduced the ethylene evolution rate by two to three folds, respectively. The pre-harvest hexanal formulation spray combined with post-harvest cold storage prominently improved the storage life along with the total soluble solids, total sugars, ascorbic acid and carotenoid content compared to untreated fruits stored in ambient conditions. Though ripening coincides with the increased activity of enzymes, the hexanal formulation spray acts predominantly in bringing down the activities of fruit softening enzymes viz. pectinmethlyesterase (43%) and polygalacturonases (37%), and antioxidant enzymes viz. peroxidase (67%) and catalase (45%), respectively.
