Advances in the development of gluten detection and quantitative determination methods

 



Authors: Krisztina Takács, Erika Koppányné Szabó, Anna Jánosi

 

1. Summary

The detection of gluten in foods is an essential, extremely important test for the protection of celiac patients. It is important to pay close attention to a safe, gluten-free diet and to the control of gluten-free foods, and for this, a reliable measurement method should be available.

Gluten and gluten-containing cereal flours are widely used in the food industry. They may be present in several food products in which lay consumers would not expect it. It can be a flavor enhancer or texturizer in various food products (e.g., meats or confectionery), and on the other hand, a gluten-free food may get contaminated accidentally with celiac active cereals during harvesting, transport, storage or processing.

Dear Readers,


In the 2nd issue of Volume LX of ÉVIK I wrote about how quickly the time of the editor-in-chief flies with the accumulation of our years, to quote my own line, the deadline is already here for issue no. 2..., with the words of Mónika Kurucz: Time flies on eagles’ wings, / … / As is uninterrupted / It all continues1. Now, in December 2018, we are celebrating the small anniversary of the renewal of ÉVIK: we have been editing our scientific journal for 5 years under the flag of WESSLING Nonprofit Kft. During this time, a total of 20 issues were published, in a volume of 2337 pages.

Phosphates in our foods: benefits and risks

Friday, December 14, 2018

Author: Mária Szeitzné Szabó


1. Summary

Phosphorus-containing food additives are authorized substances widely used in the food industry, the use of which has many technological advantages. For a long time, these compounds had been regarded as practically harmless, however, recently more and more research results warn us that their extensive use and increasing consumption increases the risk of certain civilization hazards, such as cardiovascular diseases and osteoporosis at the population level.

Food safety knowledge and awareness of primary school children

Friday, December 14, 2018

Authors: Annamária Dorkó, Ágnes Balogh-Berecz, Barbara Szabó-Bódi, Gyula Kasza

 

1.     Summary

The National Food Chain Safety Office (NÉBIH) is working to ensure the highest possible level of food safety from farm to table. As an integral part of this, particular attention is paid to minimizing risks that result from the potential lack of knowledge or from the misconceptions of consumers by its awareness-raising programs, and emphasis is put on this even in the case of young children who are most receptive to these ideas. In our paper, the results of the survey intended to form the basis of this activity and investigating the knowledge level and awareness of the children are presented.

Effect of fertilization on the fat content and fatty acid profile of sorghum flour samples

Friday, December 14, 2018

Authors: Szintia Jevcsák, Attila Bíró, Judit Remenyik, Gábor Lehocki,  Eszter Murányi, János Jóvér, Gerda Diósi, Péter Sipos

 

1. Summary

In our experiments, changes in the fat content and fatty acid composition in the flour of sorghum cultivated in growing areas treated with different nitrogen fertilizer doses were studied by the gas chromatographic analysis of the fatty acid methyl esters. The fat content exhibited a slight increase as a result of increasing fertilizer treatment, there were significant differences between the individual treatments. The fatty acid composition showed different results, depending on the treatments

Incorporating single cell proteins in the diet of IBD patients

Friday, December 14, 2018

Authors: Judit Molnár, Dávid Vasas, Balázs Ásványi


1. Summary

Worldwide, and also in Hungary, more and more patients are diagnosed with inflammatory bowel disease (IBD) each year. In the case of IBD patients, to supplement a normal diet, alternative solutions, such as, for example, the dietary use of single cell proteins intended to be examined by us are required. Ensuring the proper nutrition and liquid supply of the human body is one of the major tasks of modern food science.

Danube analysis: 50 microplastic particles per cubic meter

 

Of the Hungarian rivers investigated so far, the most microplastics were found in the Danube: 50 particles per cubic meter. During the Tiny Plastic Puzzle project, following the investigation of the river Tisza, the microplastic contamination of the Danube and its tributaries has been measured by WESSLING Hungary Kft. and its partners. In the opinion of the researchers and expert proficient in the practice of environmental protection and laboratory analyses, presented at the project conclusion conference held at the WESSLING Knowledge Center on October 10, 2018, the results of the measurements are disturbing.
