Special Issue Information

Dear Colleagues,

As in all other scientific fields, in the 21st century, microbiological research for food safety and quality is evolving rapidly; traditional analytical techniques are increasingly used alongside methods specific to molecular biology, bioinformatics and "Artificial Intelligence" (AI). Observational data have increased enormously ("Big Data”), and even standard techniques provide relevant results if used in a modern and rigorous methodological context, whether computer-assisted or not, on particular or innovative organisms or food. This Special Issue intends to give space to experimental, observational studies or systematic/narrative reviews of the literature in the field of food microbiology concerning methodologies or foods of emerging interest; in addition, studies that define, with greater precision, the quality of food and methods, along with the risks and benefits of microorganisms, are valorised.

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. Applied Sciences 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 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.

Benefits of Publishing in a Special Issue

  • Ease of navigation: Grouping papers by topic helps scholars navigate broad scope journals more efficiently.
  • Greater discoverability: Special Issues support the reach and impact of scientific research. Articles in Special Issues are more discoverable and cited more frequently.
  • Expansion of research network: Special Issues facilitate connections among authors, fostering scientific collaborations.
  • External promotion: Articles in Special Issues are often promoted through the journal's social media, increasing their visibility.
  • e-Book format: Special Issues with more than 10 articles can be published as dedicated e-books, ensuring wide and rapid dissemination.

Aflatoxins are foodborne toxins that occur naturally in various crops because of fungal contamination, particularly from two strains, namely Aspergillus flavus and Aspergillus parasiticus. Given their adverse properties, which are teratogenic, mutagenic, and carcinogenic, aflatoxins present a significant public health concern. Consequently, efforts are underway to inactivate aflatoxins and inhibit the growth of these fungi to prevent toxin formation. Since chemical treatments for food products are undesirable or even restricted in some countries, alternative approaches are also implemented. This study investigated gamma-ray (γ-ray) irradiation as a potential method for reducing aflatoxin levels. Specifically, solutions of aflatoxins B1, B2, G1, and G2 were irradiated with doses of 1, 2, 4, and 8 kGy using a cobalt-60 irradiation source. Following γ-irradiation, a notable reduction in aflatoxin levels was observed, particularly for types B1 and G1, which process higher toxicity. This finding suggests γ-irradiation as a feasible method for aflatoxin deactivation. Additionally, as a proof of concept, almond samples spiked with aflatoxins and A. flavus were irradiated. The results showed a decrease in both aflatoxin levels and microbial load in these samples. Overall, these findings indicate that γ-irradiation is a promising approach to aflatoxin reduction, microbial decontamination, and the potential extension of almonds’ shelf life. Full article
