Ukraine is ac vely implemen ng safety legisla on and certain indicators of food quality, in par cular, raw milk, to the requirements of the European Union. Modern requirements for raw milk require careful analysis of hygienic indicators. Raw milk materials supplied to "Bila Tserkva Dairy Plant" LLC and dairy plant in PJSC "Vita" of Kyiv Region were studied. The count of mesophilic aerobic and faculta ve anaerobic microorganisms (MAFAM) and the species composi on of milk microflora, in par cular, bacteria of the genus Salmonella, Staphylococcus aureus, Listeria monocytogenes, bacteria of Escherichia coli group, psychrotrophic and spore-forming microorganisms were determined by microbiological methods. Physicochemical methods were used to determine: density, mass frac on of dry ma er, soma c cell content, acidity, purity group, mass frac ons of protein and fat. According to research results, the quality of farm milk is in an order of magnitude be er than milk obtained from private households, in par cular, by MAFAM count. The technology of obtaining farm milk ensures its produc on of extra and first grades, while milk obtained in the condi ons of private households -the first grade and non-grade. According to physicochemical parameters, milk obtained under different condi ons did not differ significantly. Microbiological parameters differed significantly. The average count of MAFAM in the milk from
The procedure of the T-2 and HT-2 toxins determination in wheat grain was developed by high performance liquid chromatography according to the following criteria: specificity, linearity, limits of detection (LOD), limits of quantification (LOQ), trueness (recovery), precision, stability. It was found that the correlation coefficient (R2) for T-2 and HT-2 toxin was 0.9999. Mean recoveries from (R, %) for T-2 and HT-2 toxin at the level of 50–150 μg·Kg-1 from wheat (sample blank) were 91 and 87 %, respectively. The relative standard deviation (RSD, %) of the measurement results under conditions of repeatability and intra-laboratory precision ranged from 0.23 to 3.93 %. The limits of quantification of the method for T-2 and HT-2 toxin was 2.2 and 1.2 μg·Kg-1, respectively. These data are within the range of acceptable minimum levels in accordance with Commission Regulation (EC) No 401/2006. It is confirmed that the standards of T-2, HT2 toxins in solutions can be stored up to 7 days in a freezing chamber, a refrigerator and at room temperature in a tightly closed container without actual loss of concentration. It was found that T-2 and HT-2 in a solution cannot be stored in a lit place, because according to the data obtained, sunlight leads to the destruction of these mycotoxins by 52 % and 59 %, respectively.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
