Pesticides are used with the aim to control insects, diseases, fungi and other pests.  Along with the benefits, there are potential effects from trace amounts of residues remaining on fruits and vegetables. The objective of this study was to check for compliance with the maximum residue levels in fruits and vegetables from Kvarner region of Croatia. 14 Fourteen sorts of  vegetables and 6 sorts of fruits (n = 263), randomly selected from market,  were analysed for organochlorine, organophosphorus and fungicide residues. Multi residue analysis using GC/NPD, GC/ECD  and spectrophotometric methods were performedapplied. The results of this study indicated that though all the commodities were contaminated with pesticides, the levels were low and residues above MRL were found only in 1.52% of  samples. All other levels were below the criteria for maximum residue limits established by Croatia and the EU.

Abstract

The degree of digitalization and potential of growth in this sector are the new criteria that split the countries into various groups. The aim of this research is to find an easier and faster method of assessing the level of digitalization for countries, over different periods, having a sample 10 countries from Central and Eastern Europe. The research compares and groups these countries, determining the impact of four additional variables on their digitalization level. There were combined multiple analyses including comparative, cluster and panel analysis. As a result, we defined a new standardized indicator, named Digi-Index, which can be adapted for various time ranges, countries or study groups. Academic researchers or business practitioners can use the Digi-Index, the clusters and their characteristics to build development plans for the digital sector, based on each country's conditions, potential and influence factors.

Abstract  

Using a micro-calorimetrical DSC we have compared the acid-catalyzed inversion of sucrose in homogeneous and heterogeneous systems. Acetic acid was chosen as catalyst for homogeneous system, and several carboxylic cationites were used as heterogeneous catalysts. The kinetic apparent parameters (A, E, k ap) for all the systems were calculated from DSC data with Friedmann’s method and catalytic constant, k323 cat, was further inferred. We found that the specific catalyst efficiency, q cat, in heterogeneous system is over 5000 times higher than in case of homogeneous ones. The activity of heterogeneous carboxylic systems is still about 30 times larger than those of a strong mineral acid in homogeneous catalysis. The results indicate the high efficiency of heterogeneous systems for soft acid catalysis of the sucrose hydrolysis.

Abstract  

The kinetic parameters (reaction order, n, activation energy, E, pre-exponential factor, A, constant rate, k) for the dehydration step due to elimination of osmotic water and hydrogen-bounded water with the carboxylic groups, and for the anhydrifying step owing to the dehydration of two neighboring (-COOH) groups, were determined under non-isothermal conditions for some carboxylic resins with acrylic-divinylbenzene (DVB) matrix. The kinetic parameters were evaluated by means of isoconversional methods from (TG/DTG) thermal analysis data. The results show a dependence of the apparent kinetic parameters on the cross-linking degree, granulation, gel/macroporous matrix nature, exchange capacity and heating rate.

Caffeine is a bitter, white crystalline xanthine alkaloid that is synthesized in different parts of more than 60 plant species. In a previous study, caffeine content of 377 food samples obtained from the Hungarian market was measured by a validated HPLC technique. These analytical data were built up into a food composition database called NutriComp. Dietary caffeine intake of the Hungarian population was estimated based on the data of the National Nutritional Status Survey 2009. Daily caffeine intake of Hungarian adult males and females were 147±6.2 mg per capita (95% CI: 135–160), and 138±4.2 mg per capita (95% CI: 129–147), respectively. There was no significant difference between genders. The oldest men and women consumed significantly less caffeine than the people between 35–64 years of age. The main sources of caffeine are coffee and tea with 58–59%, and 35–37% of the total intake in men and women, respectively.

Skin-contact fermented white wines, the so-called orange or qvevri wines, have been gaining international attention from winemakers, importers, sommeliers, consumers, and journalists over the last 10 years. Sommeliers are now regularly pairing orange wines with fine cuisine. This new culinary trend is part of a general move by the consumer wishing to respect the existence of traditions and innovation, combined with a growing interest in environmental awareness and healthy options. Orange wines are made from white grapes using ancient Georgian techniques. The essence of this method is the long skin-contact fermentation in amphorae without any chemicals or specific yeast. In our work, the polyphenol content of orange wines, in particular total polyphenol and catechin content, as well as colour intensity were measured to ensure safe winemaking technology without oxidized components.
