Abstract

The mineral composition of buckwheat and products, produced from it, may significantly vary depending on growing conditions. The aim was to study features of the mineral composition of buckwheat groats different brands in the trading network Ukraine. For the experimental studies were selected samples of buckwheat groats of first grade in supermarkets of Dnieper city under three brand names: "Khutorok", "Avhust" and "Varto". Metals content measurements performed on atomic absorption spectrophotometer S-115 FCM with atomization in flame gas mixture acetylene-air. Phosphorus content was determined colorimetrically. Ash content in groats was at level 1,5–2,0%. For the total mineral content of buckwheat brand "Khutorok" probably prevailed other samples on 18,6–28,6%. Calcium concentrations in buckwheat groats different brands, according to our data, had no reliable difference and fluctuated in narrow range: 0,27–0,29 g/kg. However, the concentration of phosphorus was probably the lowest in buckwheat brand "Khutorok" and amounted to 3.70 g/kg. Phosphorus content in buckwheat trademark "Avhust" was 21,6% and the brand "Varto" – 25,7% compared with the "Khutorok". Magnesium levels in our study was 1,08–1,18 g/kg. That probably did not depend on the manufacturer of groats. Similarly, had no reliable difference compared with each analyzed sample by content of manganese (8,45–9,81 mg/kg) and cobalt (0,44–0,60 mg/kg). Analyzing the data obtained, it should be noted that the concentration of copper and zinc exceeded 50%, and the content of Lead and cadmium accounted for 30–100% of the permissible level. That may indicate a significant level of human impact on the territory of growing food raw materials. Conclusion. On the content of greater number of macro and micronutrients reliable difference between buckwheat groats of the various producers not installed. That may indicate no significant relationship mineral composition and process of manufacturing products. Found significantly higher content of phosphorus in groats of brands "Avhust" and "Varto" and iron – in groats of brands "Khutorok" and "Avhust". That shows the influence of the chemical composition of raw materials due to various agronomic production conditions on the quality of the finished product. All samples of buckwheat's groats on the content of heavy metals contain copper, Zinc, Lead and Cadmium within allowed limits.
