Progress report of the fifth period of the post-doctoral research project 1.1.2/VIAA/1/16/219

The activities over the fifth period (01.10.-31.12.2018) of the project No. “Development and application of mass spectrometric methods for the occurrence assessment of regulated and emerging mycotoxins in agricultural and dairy products in Latvia, providing contribution to the priority bio-economy sectors” were mainly dedicated to the development of method for the analysis of mycotoxins in blue and white mould cheeses distributed in the Latvian market.

Main activities and events of the fifth period where as follows:

  • Publication of a scientific article entitled "Recent applications of carbonaceous nanosorbents for the analysis of mycotoxins in food by liquid chromatography: a short review” (In Press paper) in the World Mycotoxin Journal (indexed by Scopus, WoS, CiteScore index: 1.7), doi: https://doi.org /10.3920/WMJ2018.2339 (result of WP 1, M 1.5).
  • Revision of scientific article “Occurrence of mycotoxins in herbal teas marketed in Latvia” and resubmission according to the recommendations of reviewers in the journal of analytical chemistry field - Food Additives & Contaminants: Part B (magazine indexed by SCOPUS and WoS, cit. Index 2.4).
  • Publication of additional paper within the framework of knowledge transfer – a full page proceeding of the international scientific conference “Chemical technologies; Science, Economics and Production”(November 1416, 2018, Shostka, Ukraine) entitled “Carbon nanomaterial use for the extraction of mycotoxins”, which summarizes results obtained during implementation of project’s periods 1. to 3. Available at: http://himtec.sumdu.edu.ua/doc/1_2018.pdf.
  • Participation with an oral report in the international scientific conference “EcoBalt 2018” on the content of mycotoxins in herbal tea. Conference theses available at: www.ecobalt.chgf.vu.lt/wpcontent/uploads/2018/10/Conference-book_EcoBalt.pdf (WP2, M 2.2).
  • Development of analytical method for the analysis of selected mycotoxins in cheeses (result of WP1, M. 1.1).

Work on the development of a scientific dataset on mycotoxin distribution in mould cheeses is in the progress (WP 2, deliverable 2.1.). More than 70 samples of blue and white mould cheeses including sorts produced in Latvia were purchased from different markets in Latvia. The first results of the studies indicated roquefortine C as the major mycotoxin forming blue-veined cheeses (concentrations ranged from 52 to 2674 ng/g). Mycophenolic acid was also found in 36% of the tested blue-veined cheeses such as Roquefort and other types at the concentrations ranged between 42 and 508 ng/g. Research on the mycotoxin content in cheese samples will be completed during the implementation of the next project stage.

The cooperation institution is The State Education Development Agency (SEDA). Project duration is 36 months. Total costs are 133 806 EUR where 85% is financed by European Regional Development Fund (ERDF). 

The publication was prepared on 27.12.2018.
