Emerging Freeze Drying and Spray Drying Techniques

Dear Colleagues,

The journal Pharmaceuticals is planning to publish a Special Issue titled “Emerging Freeze Drying and Spray Drying”, and I am cordially inviting you to contribute with communications, research articles, or high-quality review papers in this volume.

Microencapsulation methods are useful techniques to increase the quality of products and to protect active substances, such as polyphenols, essential oils, probiotics, and others, from various environmental factors. The most popular microencapsulation methods are freeze drying and spray drying. Spray drying is simple, fast, cost-effective, and scalable, while freeze drying is a more expensive and longer-lasting method, but it is also simple, effective, and more suitable for heat-resistant compounds.

This Special Issue aims to host research and review papers on the benefits of and comparison between freeze-drying and spray-drying techniques, using novel compounds as wall materials, and analyze the impact of process parameters and powder's physicochemical characteristics. Areas of interest include but are not limited to active compounds/wall materials interactions, characterization of emulsions/powders, biological in vitro/ex vivo/in vivo evaluation of obtained formulations, spray-dried or freeze-dried powders/cell interactions, encapsulation efficiency of active substances, and adaptability of obtained powders for pharmaceutical forms.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. 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. Pharmaceuticals is an international peer-reviewed open access monthly 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 2900 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
