THE VITAMIN AND MINERAL CONTENT OF BUCKWHEAT GROATS
Background. Nowadays the structure of Ukraine people’s nutrition has a significant deviation from a balanced formula for consumption level of vitamins and minerals. Biofortified plant material usage for food production, especially mass consumption, which is available to all segments of the population is important for solving this problem. Buckwheat groats is one of these products. Due to the emergence of new buckwheat varieties, it is appropriate to determine the content of some micronutrients. The aim of the study is a comparative analysis of vitamin and mineral content of buckwheat groats from buckwheat of 6 breeding varieties in order to select biofortified raw materials.
Material and methods. The objects of the research are varieties of buckwheat grown in the fields of the V.Ya. Yuriev Plant Production Institute of NAAS of Ukraine: Ukrainka, Yaroslavna, Kvitnyk, Kosmeya, Duimovochka, Doshchyk. The content of thiamine and riboflavin was determined by the fluorometric method, nicotinic acid by colorimetric, tocopherol and β-carotene -spectrophotometric, phosphorus -spectrophotometric, calcium -titrimetric, magnesium, manganese and iron -atomic-absorption [12–17].
Results. It was experimentally confirmed that the content of vitamins and minerals can vary considerably depending on the buckwheat variety the groats is made of. Significant differences were observed for vitamins B1, B2, B3, E, iron and manganese. The consumption of 100 g of buckwheat provides from 10 to 25 % of the daily adult micronutrient requirement, and for some of nutrients (tocopherol, magnesium, iron, manganese), this figure reaches 45-56 %.
Conclusion. Groats of buckwheat varieties Kvitnyk, Kosmeya and Duimovochka were found to be balanced in mineral and vitamin content. They can be considered as the most promising and regarded as biofortified plant material for manufacturing products of functional purpose.
Keywords: buckwheat groats, buckwheat, selection variety, vitamin and mineral composition.
