It is the end of September again. I hope that all of our readers could relax during the this year’s unusually hot summer weeks, and the way now „restlessly turns to fall, rises, falls rust on the crown, the celestial breath is cool: the sky does not heat, only smokes, the sun only sighs1”, remembering summer adventures, everyday focus shifts back to creative work. This year, there have been two additions to our editorial board: Dr. Zsolt Hantosi is responsible for English translation and proofreading of the manuscripts, and Dr. Anett Popovics checks manuscripts received for publishing, and keeps close contact with members of the Editorial board, authors of our journal, and also with organizations measuring the professional performance of scientific publications.
In our fall issue, publication of the papers of Andrea Zentai and her coworkers, the next installment of which discusses, under the leadership of Professor Árpád Ambrus, the probabilistic estimation methods of the pesticide exposure of people consuming foods. The essence of their research results is that despite the usually reassuring data obtained during the deterministic estimation of the pesticide residue exposure of the population, for certain consumer groups it is higher than the limit values of current regulation.
Publication of the manuscripts of the research group on this topic will continue in the December 2015 and March 2016 issues. This way, together with our Summer 2014 issue, a regular pesticide tetralogy about the statistical analysis of residual amounts of pesticides will be available for you in our journal. The large number of analytical data that serve as the basis for the calculations in the paper about the probabilistic estimation procedure is pubilshed in five long tables. In his work, Professor András S. Szabó discusses a surprising topic: the essentiality of nickel, which is an element of the d-block, i.e., a transition metal. I have to admit that, before reading the manuscript, I would have answered the question whether nickel is an essential element for any living being with a „no”. Well, according to what is described in the paper of Professor Szabó, it is an essential element for humans, although symptoms of its deficiency have not yet been reported in the scientific literature.
At the same time, we should note that, approximately a decade ago, due to the technology used then, margarine products contained nickel in amounts exceeding the allowable limit. For certain individuals, nickel exposure can cause allergic reactions – reminds us the author of the paper. Katalin Vajda and her coworkers discuss in their manuscript, under the leadership of Professor Jenő Szigeti, the microbiological conditions of low temperature food preparation that has been gaining popularity in recent years. Sterilized meat products were infected with pathogenic microbes, and then subjected to heat treatment using the sous-vide technology. Results of this challenge test are reported in the article.
The mosaic about the state of world economy is completed by a manuscript about one of the most well-known and most often consumed stimulants of our age. The effect of different roasting conditions on changes in the polyphenol content of arabica and robusta coffees was investigated by Anita Imre and her coauthors. For a long time, coffee was considered an expressly harmful beverage, even though the different compounds with a reducing effect that are found in it can have beneficial effects on the health of a person consuming coffee in moderation. The decrease in the amount of reducing substances due to roasting was determined by the research group by measuring the FRAP (ferric reducing ability) value.
Today, in relation to the sustainability of the living environment of mankind, an issue that is raised frequently is that of wasting food. According to the surveys of the FAO, this behavior that can be condemned from an environmental protection, an ethical and a food security point of view as well, affects roughly one third of the food produced in the world. It also our duty to speak up against food waste, because currently available resources of the world could provide livelihood to 9 to 10 billion people in „respectable poverty”, if distribution were more fair compared to today’s practice2. This is the topic of the article of NÉBIH experts, Barbara Bódi and Gyula Kasza. Our Fall issue is concluded with the synopsis of Csilla Kurucz about standardization, the international overview and the domestic panorama. In the latter, an account of the September 3 editorial board meeting is included as well. We wish all our readers useful reading and good luck in this period full of beautiful fall atmosphere:
