Compositional Changes in the Extra Virgin Olive Oil Used as a Medium for Cheese Preservation.

The influence of semi-hard (C1), hard (C2), and soft whey cheese (C3) immersed in extra virgin olive oil (EVOO) on its oxidative and hydrolytic parameters, fatty acids, and phenolic composition during two months of simultaneous storage was investigated. Accelerated hydrolytic and oxidative degradation was noted in EVOO stored with the immersed cheese compared to control oil. Oxidation indicator (K), myristic (C 14:0), and -oleic fatty acid (C18:1t) exceeded the prescribed limit for the EVOO category in oils stored with immersed C1 and C2, which indicated that standard analytical parameters are ineffective as tools to examine the declared quality and authenticity of such topping oils.

Large-scale mitogenome sequencing reveals consecutive expansions of domestic taurine cattle and supports sporadic aurochs introgression.

The contribution of domestic cattle in human societies is enormous, making cattle, along with other essential benefits, the economically most important domestic animal in the world today. To expand existing knowledge on cattle domestication and mitogenome diversity, we performed a comprehensive complete mitogenome analysis of the species (802 sequences, 114 breeds). A large sample was collected in South-east Europe, an important agricultural gateway to Europe during Neolithization and a region rich in cattle biodiversity.

Beneficial Effects of Laurel ( L.) and Myrtle ( L.) Extract on Rat Health.

Polyphenols of Laurel and Myrtle exhibit structural diversity, which affects bioavailability, metabolism, and bioactivity. The gut microbiota plays a key role in modulating the production, bioavailability and, thus the biological activities of phenolic metabolites, particularly after the intake of food containing high-molecular-weight polyphenols. The aim of this study was to investigate whether the polyphenolic components of Laurel and Myrtle aqueous extract have beneficial effects on rat health.

Cyclic imines in shellfish and ascidians in the northern Adriatic Sea.

The aim of this study was to determine the occurrence of the most representative cyclic imines (CIs) gymnodimine (GYM), pinnatoxin G (PnTX-G), and 13-desmethyl SPX C (SPX1) in Mediterranean mussels ( Lamarck, 1819) (n = 416), European oysters ( Linnaeus, 1758) (n = 104), Queen scallops ( Linnaeus, 1758) (n = 52) and edible ascidians of the . (n = 104) originating from nine harvesting and breeding areas in the northern part of the Adriatic Sea using ultra-performance liquid chromatography-tandem mass spectrometry (LC-MS/MS). All CI concentrations were far below the guidance level of 400 μg SPXs/kg proposed by the EU Reference Laboratory for Marine Toxins.

Efficacy of low pressure DBD plasma in the reduction of T-2 and HT-2 toxin in oat flour.

T-2 and its major metabolite HT-2 toxin are naturally occurring contaminants in cereals, with the highest concentrations determined in oats. Because of their toxicity and resistance to conventional methods used in mycotoxin degradation, development of new effective procedures for reduction of T-2/HT-2 toxin levels is needed. The aim of this study was to investigate the effect of different gas types within various timeframes on the efficiency of T-2 and HT-2 toxin degradation by low pressure dielectric barrier discharge (DBD) plasma in oat flour.

Analytical methods used for the authentication of food of animal origin.

Since adulteration can have serious consequences on human health, it affects market growth by destroying consumer confidence. Therefore, authentication of food is important for food processors, retailers and consumers, but also for regulatory authorities. However, a complex nature of food and an increase in types of adulterants make their detection difficult, so that food authentication often poses a challenge.

Deoxynivalenol and zearalenone in unprocessed cereals and soybean from different cultivation regions in Croatia.

The aim of this study was to investigate the occurrence of deoxynivalenol (DON) and zearalenone (ZEN) in unprocessed cereals and soybean sampled in 2014 and 2015 from different fields located in Croatian regions. A total of 306 samples were analysed for DON and 415 samples for ZEN concentrations using quantitative ELISA methods. In 2014, DON and ZEN were determined in all samples in the mean concentrations of 1,461 ± 2,265 µg/kg and 656 ± 853 µg/kg, respectively, while in 2015 these means were 2,687 ± 2,731 µg/kg and 1,140 ± 1,630 µg/kg, respectively.

Survey of T-2/HT-2 toxins in unprocessed cereals, food and feed coming from Croatia and Bosnia & Herzegovina.

The aim of this study was to investigate into the level of T-2/HT-2 toxins in different unprocessed cereals (n=201), as well as in marketed cereal-based products (n=58), feed components (n=191) and feedstuffs (n=91) coming from Croatia and Bosnia & Herzegovina. The number of positive samples of unprocessed cereals for food production (>LOD) ranged from 30.4% in barley to 68.

Citrinin in cereals and feedstuffs coming from Croatia and Bosnia & Herzegovina.

The aim of this study was to investigate the occurrence of citrinin in different cereals (n = 341) and feedstuffs (n = 67) coming from farms and feed factories established in Croatia and Bosnia & Herzegovina. The highest mean citrinin concentration (103 ± 102 µg/kg) was observed in cereals sampled in Bosnia & Herzegovina during 2014, although significantly different levels between the two countries were not observed. Across the cereal samples, the maximal citrinin concentration was determined in wheat (429 µg/kg), while across the feedstuffs, the highest concentration was found in pig feed (63 µg/kg).

Ochratoxin A reduction in meat sausages using processing methods practiced in households.

The aim of this study was to investigate the possibilities of ochratoxin A (OTA) reduction in home-made meat products. Meat sausages (n = 50) produced from raw materials coming from pigs exposed to OTA-contaminated feed, were subject to common heat processes practiced in households (cooking, frying and baking). Concentrations of OTA in pre- and post-processed products were quantified using a validated immunoassay method, enzyme-linked immunosorbent assay, and confirmed using a high-performance liquid chromatography with fluorescence detection.

Detection and characterisation of hepatitis E virus in naturally infected swine in Croatia.

Hepatitis E is a viral zoonotic disease infecting swine worldwide. Since pigs represent a likely animal reservoir for the hepatitis E virus, the epidemiology of naturally occurring hepatitis E was investigated in Croatian swine herds. Nearly all tested animals were seropositive for antibodies against the hepatitis E virus (55/60, 91.

Ochratoxin A in raw materials and cooked meat products made from OTA-treated pigs.

The aim of this study was to determine ochratoxin A (OTA) concentrations in the raw materials and cooked meat products made from pigs sub-chronically exposed to OTA. The treated animal group (n=5) was administered with 300 μg OTA/kg of feed for 30 days, whereas the control group (n=5) was left untreated. OTA concentrations were quantified using immunoassay (ELISA) and high performance liquid chromatography with fluorescence detection (HPLC-FD).
