Special Issue Information
Dear Colleagues,
Edible films and coatings are characterized as thin layers of edible materials that can be applied to food products and play various important roles, such as in protecting the product from mechanical damage or physical, chemical, and microbiological activities. The main difference between these two forms is that an edible coating is a thin layer formed as a coating on a food product, while an edible film is a thin, preformed layer that, once formed, can be placed on or between food components or even sealed into edible pouches. They find applications, especially for highly perishable products, such as horticultural products, or can serve as standalone edible packaging materials. Their functions are based on a range of properties such as availability, mechanical resistance, optical properties, and the barrier effect against gases or water vapor as well as cost and sensory acceptability. Although edible films and coatings are not expected to completely replace conventional packaging materials, they can be used to extend food stability by reducing the exchange of moisture, gasses, lipid, and volatiles between a food and its surrounding environment. Typically, they can be produced from biopolymers (proteins, polysaccharides, and/or lipids); however, novel materials are still being evaluated, especially byproducts and residues, and should conform to achieving sustainability in food production. Edible films and coatings based on fruits and vegetables may be produced from a single macromolecule type, blends, or even composites (single or multilayers). They can be prepared from purees, pomaces, or extracts and show different functions, facilitating their application as protective coatings, thin films, active bags, wraps, leathers, or papers.

Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Molecules is an international peer-reviewed open access semimonthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2700 CHF (Swiss Francs).
