Special Issue Information

Dear Colleagues,

This Special Issue is dedicated to presenting cutting-edge research and comprehensive reviews that investigate the intricate mechanisms of food processing, shedding new light on the underlying chemical reactions and compositional changes involved.

Food processing profoundly influences the physicochemical properties of food, affecting its molecular organization, structural integrity, and functional performance. Understanding the complex interactions that occur during processing is essential for advancing the quality, safety, and nutritional value of food products. For this Special Issue, we invite contributions that focus on the transformation of key food constituents—such as proteins, polysaccharides, lipids, and bioactive compounds—across a range of processing techniques, including thermal, mechanical, enzymatic, and emerging non-thermal technologies.

A central focus of this Issue will be on elucidating the connections between food composition, structure, and resulting properties. By uncovering these relationships at the molecular scale, researchers can better understand how different processing methods affect physical attributes like texture and microstructure, as well as health-related properties such as nutrient stability and bioavailability. These outcomes ultimately shape consumer acceptance and sensory evaluation.

We particularly encourage submissions that utilize advanced analytical methodologies and interdisciplinary strategies. Studies that integrate fundamental scientific understanding with practical applications in food science and technology are highly encouraged.

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. 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). 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.

The study aimed to characterize the quality and evaluate the content of bioactive substances in cold-pressed pumpkin seed and walnut oils obtained from the specific varieties (Cucurbita pepo var. oleifera and Juglans regia L.). The analyses included the determination of acid value, peroxide value, and anisidine value. The content of chlorophylls and carotenoids was identified, and the fatty acid, phytosterol, and tocopherol profiles were characterized. The results were subjected to principal component analysis and compared with the physicochemical parameters of other popular niche oils. It was shown that both oils tested have unique, relatively simple fatty acid profiles (only 5–6 dominant acids were identified). In addition, significant differences in squalene content were observed: pumpkin seed oil showed a higher concentration than other vegetable oils. In contrast, walnut oil was found to lack squalene, which is atypical among the analyzed niche oils. Full article
