Special Issue Information
Dear Colleagues,
The term "carrageenan" refers to a group of non-branched anionic polysaccharides found in red algae. Macromolecules of carrageenans are built from repeating carrabious units, each of which consists of two units. Both units may be variously sulfated D-galactopyranose residues, or one of the units may or may not be a sulfated 3,6-anhydro-D-galactopyranose residue. There are various types of "ideal" carrageenans, denoted by Greek letters, of which three types are commercial: λ-carrageenan exhibits the properties of a thickener, while ι- and κ-carrageenans exhibit the properties of gelling agents. The network nodes of the carrageenan gel are spiralized areas at the points of interlacing of polysaccharide chains. Carrageenans are capable of forming supramolecular complexes with other biopolymers, in particular, polysaccharides and proteins, in the aqueous phase. Carrageenans are non-toxic and biodegradable and have antiviral activity, due to which they are widely used both in pure form and as part of complexes in the production of functional materials used in biotechnology, medicine, pharmaceuticals, the food industry, and other industries related to human health and nutrition. This Special Issue welcomes all contributions on the formation of complexes, the functional properties of foams, emulsions and gels based on carrageenans, and their rheological behavior and surface activity. Topics related to the use of carrageenans in the above industries are also welcome.

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. Polymers 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). 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.
