Honey is a natural sweetener and as such it can be greatly affected by fraudulent practices like mislabeling (blossom honey sold as honeydew honey) or the addition of illegal substances (syrup or water). Phenolic compounds, flavonoids and phenolic acids, are the most abundant antioxidant nutritive constituents and proved to be beneficial to human health. The concentration and the presence of these compounds are strictly connected to the geographical and/or the botanical origin of the honey. To this end, a method has been optimized and validated for the simultaneous determination of 25...

Nowadays more and more people are opening up to a healthier way of life and follow a diet that includes foods which promote healthy aging. Some of these foods are superfoods and superherbs that possessed functional health properties beyond its nutritive value. These foods containing exogenous nutrient and phytochemical antioxidants that could protect the human body from damage arising from chronic oxidative stress caused by excessive production of free radicals. The main purpose of this work was the study of superfoods and superherbs produced in Greece and which consist the raw material for...

Water is a basic human need and is provided to the crew of International Space Station (ISS) from the water storage/transfer systems that are placed in there. Except of the direct regular supply of drinking water, the development of proper water recycling systems is equally critical as the employment of reliable automatic water quality monitoring systems. A fully automated on-line analyzer for ammonium determination in consumed drinking water and/or recycled hygiene water produced on board the ISS is needed according to ESA requirements. In this work, a trade-off methodology similar to a...

As a consequence of general awareness with respect to food safety issues, there is a current requirement that eggs have a clean shell, devoid of microbial contamination. This work refers to a method of evaluation of antimicrobial action of cold atmospheric plasma, a technology employed herein for the decontamination of egg surface. The treatment with cold atmospheric plasma is a new technology that achieves inactivation of microorganisms potentially contaminating the surface of foodstuffs. Several microorganisms can contaminate eggs during production and/or processing, as well as during food...

Ochratoxin A is structurally related compounds produced as secondary metabolites mainly by toxigenic strains of Aspergillus and Penicillium species in/on food and feeds. Among the mycotoxins, ochratoxin A has several toxicological effects such as nephrotoxic, hepatotoxic, neurotoxic, teratogenic and immunotoxic. As a result of their potential threat for health, regulations on mycotoxins have been established in many countries in order to protect consumers from their harmful effects. Based on the regulatory limits, accurate and reliable determination of mycotoxins in foods becomes very...

In this study, a highly selective molecular imprinted polymer (MIP) sorbent was used for the determination of six sulfonamides (sulfanilamide, sulfacetamide, sulfadiazine, sulfathiazole, sulfamerazine and sulfamethizole) from milk samples. MIPs particles were applied as sorbent in the solid phase microextraction (MIPSPE). The determination was achieved by an accurate and sensitive liquid chromatographic analytical method which was developed and validated according tothe European Union Decision 2002/657/EC. Several experimental parameters such as the amount of the MIP and milk, the amount and...

The Institute of Public Health is the first public health institution in the FYROM that has established Quality Management System according to ISO/IEC 17025. The accreditation has been granted by the National Institute for Accreditation in December 2006. Since then, the maintenance and improvement of the Quality Management System remains a key element in our policy. It is well-known that one of the elements by which laboratories can demonstrate their competence is through participation in Proficiency Testing (PT) activities. Therefore, our laboratory adopted practice to participate in at...

Chemical metrology is a specific field where the process in order to achieve a traceable and comparable results is difficult to be standardized. Moreover, a more holistic approach is required for the evaluation of their reliability. On the other hand, a continuous increasing number of contaminants are intended to be determined in foods and for a high percentage of them e.g. the more toxic, at very low quantification levels. At these low levels, close to detection, the classical way of GUM using statistical techniques for the determination of uncertainty, as the range of values that could...

Small changes in the 18 O/ 18 O ratio can provide a fingerprint that provides a unique identifier for the origin of particular compounds within a food, which has been proved be a valuable tool for fighting against fraud food. As the backbone of triglyceride in fat, glycerol contains three non-exchangeable oxygen, which could be used to reveal the biosynthetic origin of corresponding fat. However, the need for highly pure glycerol using tedious procedures for off-line IRMS methods or GC-IRMS analysis limited the researches and applications of glycerol 18 O/ 16 O ratio in edible oil...

In this study, it was determined the content of some amino acids from 3 types of wheat based bread: White, Whole Wheat and Sylvester Graham before and after RF treatment. The amino acids content was monitored at two different moments: T0 - initial moment and at T10 - after 10 days of storage at in controlled conditions. The main conclusion of this preliminary study was that treatment with RF at 100 ºC does not affect the nutritional value of the core regarding the content of analysed amino acids. Further it is necessary to be studied the effects of RF treatment over the general nutritional...
