Occurrence of chloropropanols and glycidol esters in foods   – A literature review

Erzsébet Bognár

Chloropropanols and glycidol are transformation products that form during food production, essentially contaminants that form during food processing. Since their production conditions are similar, they are usually mentioned together in the relevant literature, as chloropropanols and related substances. The presence of chloropropanols was first observed in connection with acid-hydrolyzed vegetable proteins, however, they also occur in other foods. They have been detected in fried potatoes, cooking oils, but they also occur in roasted and cooked meats, snacks, biscuits, and practically all thermal-treated products that contain fat.

Welcome 2017/2

Tuesday, September 06, 2016

Dear Readers,

Now, when I write these lines, I’m in a boarding house in Heves county, while „…I listen to how the pine ribs of the mountains creak, because they are being embraced by the giant arms of passing1…” Outside, the elements are raging, the floodgates of heaven have opened completely, summer rain and hail is pouring down, and the wind is twisting angrily the trees and bushes of the vineyard. Nevertheless, it is summertime, the air is excellent, and despite the temporary bad weather, we can look forward to the vacation.

However, before going on a vacation, I would like to recommend to your attention the summer issue of ÉVIK, the leading material of which was chosen to be the review work of Erzsébet Bognár.

Evaluation of the mineral content of winter wheat in light of/as a result of the new studies

Tuesday, September 06, 2016

Author: Zoltán Győri

1. Summary


Today, more and more emphasis is placed by food and nutrition research and practice on the chemical composition of winter wheat, which is considered a staple food, both in terms of organic and inorganic macro- and microcomponents. This attention is the result of several factors, of which should be highlighted the expansion of the possibilities in instrumental analysis (HPLC, HPLC-MS, ICP-OES, ICP-MS), as well as the often changing factors closely related to cultivation technology (varieties, hybrid, plant protection, fertilization, frequency of weather extremes).

DON, F-2 and T-2 mycotoxin assay of plant-based feedstock raw materials using the ELISA method

Tuesday, September 06, 2016

Authors: Helga Tima, Eleonóra Kecskésné Nagy, Anita Rácz, Gabriella Kiskó, Csilla Mohácsiné Farkas

1. Summary


In our study, plant-based raw materials, used for feeding different animal species, are investigated, using a competitive ELISA method. The raw materials most commonly used for feeding (soy and alfalfa pellets, as well as wheat, barley and maize) were used in the tests. Of Fusarium mycotoxins, deoxynivalenol (DON), zearalenone (F-2) and T-2 toxins were measured. Measurement results were evaluated using the mathematical- statistical program RStudio. In our experiment, we found that all three mycotoxins tested could be detected in all of the samples, but the values were not quantifiable with acceptable precision in each case.

The historical role of milk and dairying in shaping European societies

Tuesday, September 06, 2016

Author: László Varga

1.       Summary


Based on results recently published in the scientific literature, the author briefly outlines in this mini-review how dairying has become, over thousands of years, a basic activity of humankind. Following the domestication of cattle, goats and sheep, which had begun approximately 10,500 to 11,000 years ago in the Middle East, milk was already in use in northwestern Anatolia by the seventh millennium BC. In lack of lactase, however, milk consumption resulted in unpleasant outcomes (e.g., flatulence, cramps, diarrhea, etc.) in the vast majority of prehistoric farmers.

Authors: Gábor Szunyogh, Réka Zanathy, Nikoletta Hollinger, Tamás János Szigeti


Hungary’s most important food safety conference and exhibition took place with more than 300 participants, 33 exhibitors and 60 presentations. The focus of the conference titled Hungalimentaria, organized by the National Food Chain Safety Office (NÉBIH) and WESSLING Hungary Kft., an operator of independent laboratories, was on packaging materials this time but, in addition to authority considerations, laboratory analyses and legal regulation, the most important food analytical issues of our age were also covered at the conference, from microplastics, through dietary supplements and pesticides, to organic foods. Several new studies, analyses and methods were presented, and these are reported in detail by the scientific media partner of the event, the Journal of Food Investigations in the compilation below.

EFSA: safe infant formulas

Follow-on formula with a protein content of at least 1.6 g/100 kcal made from either cow or goat’s milk is safe and suitable for infants living in Europe, EFSA says. Current EU legislation sets the minimum protein content at 1.8 g/100kcal.

For the scientific assessment, EFSA considered the dietary protein requirements of infants from 6 to 12 months of age, the protein content of breast milk during the first year of lactation, protein intake from dietary surveys in healthy European infants, and two specific studies.
