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. A material that can be put to good use has been compiled by the author on the chemistry and the toxicological characteristics of chloropropanols and glycidol esters, unwanted byproducts that form in food industrial heat treatment technologies.
In our summer issue, the topic of two papers is related to the history of the profession, and can be viewed as a kind of retrospective.
The manuscript of Zoltán Győri deals with the microelement content of Hungarian wheat. The test material consisted of wheat grains harvested several decades ago, and some of the valuable samples were well over 100 years old. Thus, the paper provides priceless data on the composition changes that took place over the last 150 years.
In his article, László Varga looks back not at hundreds of years, but at several millennia. The topic of his work is the development of dairy farming and the changes in the processing and consumption, by mankind, of milk produced by different animal species. Based on the data of his literature review it can be assumed that humans were originally unable to digest milk sugar, i.e., lactose. Lactose tolerance, also known as lactose persistence, developed in about 25% of the human population over the course of history.
The manuscript of Helga Tima et al. reports on the enzyme-based analysis of the Fusarium mycotoxin contamination of feeds of plant origin. The ELISA tests used by them are suitable for fairly sensitive analyses that are performed rapidly; in addition to highly sensitive, more precise, selective techniques using large instruments, they can be useful for the assessment of mycotoxin contamination, for example, due to climate change, in the future.
The Rapid Alert System for Food and Feed (RASFF) of the European Union has been serving the safety of the EU food chain for nearly four decades. In the article of Enikő Dorogházi et al., the history and the operation of the alert system, having better and better technical possibilities each year, are presented with a few interesting cases.
I hope that all of our Readers will find something interesting to read in our summer issue again. After the first six months of work well done, I wish our Readers a pleasant vacation.
