Special Issue Information

Dear Colleagues,

As sustainable and nutrient-dense ingredients, microalgae offer immense potential to address global food security and nutrition challenges. We welcome contributions that focus on innovative cultivation techniques, harvesting methods, and processing technologies for edible microalgae. Studies that investigate the incorporation of microalgal biomass into various food products, their effects on nutritional composition, their functional properties, and consumer acceptance are of particular interest.

We also encourage submissions on the use of microalgae in developing novel food products, such as meat analogues and fortified foods. Additionally, research on the scalability and economic feasibility of microalgae-based food production is highly relevant. This Special Issue will provide a comprehensive overview of the current state and future directions of microalgae in food systems, bridging the gap between fundamental research and practical applications in the food industry.

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 250 words) can be sent to the Editorial Office for assessment.

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. Foods 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 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.

Arthrospira platensis and Chlorella vulgaris are popular commercialised microalgae due to their benefits and relatively easy large-scale cultivation. However, recent advances in biotechnology have revealed a new range of promising strains with industrial potential but limited current markets. To bridge the gap in the existing literature, this study provides a comprehensive and simultaneous biochemical characterisation within a unified analytical framework of six additional strains: Phaeodactylum tricornutum, Tetraselmis chuii, Nannochloropsis oceanica, Scenedesmus almeriensis, Tisochrysis lutea, and Skeletonema costatum. The analyses included macromolecular composition, amino acid and fatty acid profiles, and volatile organic compound composition. Key results identified P. tricornutum and T. chuii as high-quality protein alternatives, reaching protein concentrations of 31% and 41% (dw), respectively, with essential amino acid profiles (arginine and tryptophan) that match commercial standards. Additionally, specific carbohydrate and lipid strengths were identified: P. tricornutum showed a high carbohydrate content (37%), while N. oceanica exhibited elevated levels of palmitic, palmitoleic, eicosapentaenoic, and arachidonic acids, marking them as versatile candidates for nutritional applications. Finally, volatile organic compound analyses revealed distinct aroma profiles, highlighting the potential of less-exploited microalgal strains for the food and feed sectors. Full article
