Special Issue Information

Dear Colleagues,

Food contamination constitutes one of the most important potential food safety hazards and risks. Traditionally, the contamination of fresh and processed foods includes biological, physical, chemical, and allergenic hazards which can derive from microorganisms, natural toxins, chemical compounds, packaging materials, and poisons. A single hazard can also introduce more than one type of contaminant.

This Special Issue focuses on the conventional and emerging technologies for the monitoring, detection, and control of food contaminants. Additives, microbiological issues, and pesticide and animal drug residues are all major concerns.

Topics of interest for this Special Issue include, but are not limited to:

  • Methods for controlling contamination in food processing (GMPs, HAACP, packaging, temperature, sanitation, freezing, UV radiation, and others);
  • Technologies for decontamination (heat, radiation, chemicals);
  • Conventional techniques (spectroscopic/colorimetric techniques, chromatography, immunoassays, etc.);
  • Nanomaterials and biosensors for detecting food contaminants;
  • Emerging technologies (ultrasound, plasma, nanotechnology, natural antimicrobials, etc.).

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. Processes 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 2400 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.

This research evaluated two methods of arginine encapsulation, melt emulsification and nanoprecipitation, using a lipid matrix of carnauba wax and commercial polymers (Eudragit®) as a protective material. The ratios of wax–arginine were 1:1, 2:1, 3:1, and 4:1, while those of Eudragit [...] Read more.
This research evaluated two methods of arginine encapsulation, melt emulsification and nanoprecipitation, using a lipid matrix of carnauba wax and commercial polymers (Eudragit®) as a protective material. The ratios of wax–arginine were 1:1, 2:1, 3:1, and 4:1, while those of Eudragit® RS:RL were 30:70 and 40:60 in proportions of 1:0.5 and 1:1 Eudragit®–arginine. The microcapsules were morphostructurally characterized by scanning electron microscopy, and a microelement analysis was performed via energy-dispersive X-ray spectroscopy and Fourier transform infrared spectroscopy. Additionally, in vitro digestibility was used to determine the protection efficiency. Both encapsulated systems presented regular (crystals) and spherical (microcapsules) polyhedral morphologies. Qualitative nitrogen decreased significantly as the wax ratio increased in the wax–arginine formulations. The formulations with a 1:1 Eudragit:–arginine ratio (1000 mg arginine) produced a higher nitrogen content in the encapsulated systems than the formulations containing 500 mg of arginine. The 2:1 and 3:1 wax–arginine formulations had the lowest degradability after 5 h of rumen fluid exposure (40.7 and 21.26%, respectively) in comparison with 100% unencapsulated arginine. The 3:1 wax–arginine formulation is an efficient encapsulating system which protects against rumen degradation. The more intense absorption bands at 1738 cm−1 and 1468 cm−1 associated with the C=O and C-H groups in carnauba wax indicate that arginine was more protected than in the other systems. Full article
