Grilling has become a widespread method of thermal food processing. However, food prepared in this way may be a source of carcinogenic organic compounds, such as polycyclic aromatic hydrocarbons (PAHs). The present study aimed to evaluate the impact of different marinades and grilling tools on PAH contamination of chicken breast tenderloins. Togeth...

Grilling has become a widespread method of thermal food processing. However, food prepared this way may be a source of carcinogenic organic compounds, such as polycyclic aromatic hydrocarbons (PAHs). The present study aimed to evaluate the impact of different marinades and grilling tools on PAH contamination of chicken breast tenderloins. Together...

Dear Colleagues, Polycyclic aromatic hydrocarbons (PAHs) represent a highly diverse group of chemical contaminants, many of which possess potential mutagenic, genotoxic, and carcinogenic properties. The presence of PAHs in food can result from environmental contamination and can be generated during thermal processes of food production and processin...

The antioxidant capacity and nutritional value of honey are significantly dependent on the content of phenolic compounds. The aim of this study was to compare the antioxidant properties and color of selected honeys and manuka honeys available in the Polish market. The results showed quantitative differences in phenolic acids, phenolic content and a...

To ensure food safety and protect human health, the levels of polycyclic aromatic hydrocarbon (PAH) contamination in model smoked-pork meat products were examined to select which type of casing and variant of raw material contributes to minimizing the content of PAHs in the final products. The sausages were smoked in a steam smoke chamber with an e...

The ABTS and DPPH methods are among the most popular assays of antioxidant activity determination. Attempts to adapt them to different analytes and the search for the highest values of antioxidant activity has resulted in a large variety of assay conditions to be presented in the literature, including the way the measurement is made. This makes it...

Due to the fact that consumers are looking for new, health-promoting products, there is a growing interest in various ingredients with a high biological activity that could enrich conventional foods. As is known, chia seeds are a rich source of various health-promoting compounds. The objective of this study was to determine the content of selected...

Levels of polycyclic aromatic hydrocarbons (PAHs) in cocoa beans of several varieties originating from different countries and their derived products from one technological line were examined. PAHs analysis was performed using HPLC-FLD/DAD and confirmed by GC-MS. Significant differences in total 19 PAHs contents between raw cocoa beans of different...

Volatile aromatic substances are the main factors contributing to the acceptability of cocoa products. The beneficial effect of fat-free ingredients of cocoa beans on human health has been scientifically proven. This encourages the consumption of cocoa products as well as further research on improving their processing technology. The aim of this st...

The aim of this study was to evaluate the effect of a 2% chia seed oil addition to natural yogurt on its quality and to determine whether chia seed oil can be used as an additive in fermented milk products. The dominant species of microorganisms found in yogurt was Lb. delbruecki subsp. bulgaricus. The number in natural yogurt varied from 6.2 to 6....

The aim of this research was to establish the effect of mild roasting on coffee beans contamination level by polycyclic aromatic hydrocarbons (PAHs). The materials investigated were green Arabica and Robusta coffee beans imported from different countries, as well as those already roasted. The experiment was carried out in a coffee-roasting plant, w...

The levels of 4 compounds from the group of light PAHs listed by the US EPA and 15 PAHs listed by the EU Scientific Committee on Food were determined in selected unconventional oils. PAHs determination was performed by high-pressure liquid chromatography with fluorescent and diode array detectors (HPLC-FLD/DAD). Similar quality profiles of PAHs, wi...

The levels of 4 compounds from the group of light PAHs listed by the US EPA and 15 PAHs listed by the EU Scientific Committee on Food were determined in commercially available infant formulae, follow-on formulae and baby foods. PAHs determination was performed by high-pressure liquid chromatography with selective detectors (HPLC–FLD/DAD) and confir...

S u m m a r y The qualitative and quantitative analysis of polycyclic aromatic hydrocarbons contami-nation in selected popular brands of fruit and herbal teas was performed using GC-MS method. Among all teas similar quality profiles of PAHs were observed. In all determined compounds 4 light PAHs (phenanthrene, anthracene, fluoranthene, pyrene) from...

The objective of this research was to determine the contamination of infant formulae, follow-on formulae and baby junior foodstuffs by PAHs: 4 compounds from the group of light PAHs listed by EPA and 15 compounds listed by The Scientific Committee on Food UE. The research material constituted commercially available infant formulae and follow-on for...

According to the Commission Recommendation 20005/108/EC further analyses of 15 genotoxic PAHs (listed by The Scientific Committee on Food) in food are necessary. The objective of this research was to study contamination of canned smoked fish products in oil by these 15 PAHs. The material investigated were canned smoked sprats in oil available in Wa...

The PAHs content in four groups of meat products industrially and traditionally smoked was determined. Methodology applied for the study included fat’s extraction, PAHs isolation using GPC and consequently qualitative-quantitative compound’s determination by HPLC-FLD/DAD. Mostly traditional method of smoking affected the higher total PAHs contamina...
