Special Issue Information

Dear Colleague,

In the last decades, theoretical and technological developments in emulsions have opened up new opportunities for the food industry. This has led not only to a wide variety of emulsion-based foods, but also to innovation in formulations leading to efficiency and sustainability. In this field, the expansion of natural ingredients (proteins, polysaccharides, starches, and dietary fibers), the modulation of formulations, the extension of preparation techniques, and the regulation of the structure–property relationships of emulsion systems have been of great interest. The behavior of water, edible oil, stabilizers, and additives at the interface and in the continuous phase, as well as the interaction between these components, have become important factors in the study of overall product quality. In addition to traditional emulsion products such as homogenized milk, dressings, sauces, and cream, the recent advances in delivery vehicles, multifunctional edible films, fermented dairy systems, and low-calorie foods have attracted interest.

We welcome both original research and review articles on topics including, but not limited to:

  • The development and utilization of novel food emulsion ingredients;
  • Novel technologies for the preparation of food emulsions;
  • Relationship between the structure of emulsifiers and the properties of emulsions;
  • Interactions of common components in food emulsions at interfaces or in continuous phases;
  • Applications of emulsion systems in the food industry;
  • Upgrading traditional food emulsion formulations.

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. Foods is an international peer-reviewed open access semimonthly journal published by MDPI.

Cream-type emulsions containing candelilla wax-based oleogels (EC) were analyzed for their physicochemical properties compared to palm oil-based creams (EP). The microstructure, rheological behavior, stability, and color of the creams were determined by means of non-invasive and invasive techniques. All the formulations exhibited similar color parameters in CIEL*a*b* space, unimodal-like size distribution of lipid particles, and shear-thinning properties. Oleogel-based formulations were characterized by higher viscosity (consistency index: 172–305 mPa·s, macroscopic viscosity index: 2.19–3.08 × 10−5 nm−2) and elasticity (elasticity index: 1.09–1.45 × 10−3 nm−2), as well as greater resistance to centrifugal force compared to EP. Creams with 3, 4, or 5% wax (EC3–5) showed the lowest polydispersity indexes (PDI: 0.80–0.85) 24 h after production and the lowest instability indexes after environmental temperature changes (heating at 90 °C, or freeze–thaw cycle). EC5 had particularly high microstructural stability. In turn, candelilla wax content ≥ 6% w/w accelerated the destabilization processes of the cream-type emulsions due to disintegration of the interfacial layer by larger lipid crystals. It was found that candelilla wax-based lipids had great potential for use as palm oil substitutes in the development of novel vegan cream analogues. Full article
