Elemental composition of white lupine grain

Abstract

The study was carried out to study the elemental composition of various parts of the grain of white lupine varieties Gamma, Dega and Deter 1, which were cultivated in 2009-2011. in the North- East of the Central Black Earth Region. The content of 19 elements was determined at the Belgorodsky State Center for Agrochemical Service. The elemental composition of grain and its parts has been studied. Intensive consumption of chemical elements allows white lupine to have a unique chemical composition of the grain, which shows that the content of many chemical elements standardized in feeding is much higher than in the seeds of other leguminous crops. In terms of manganese content, white lupine is a concentrator plant. In the grain of white lupine, nitrogen (6.82±0.25 %), phosphorus (0.45±0.07 %), potassium (1.37±0.17 %), magnesium (0.17±) accumulate in significant quantities 0.02 %), sulfur (0.31±0.02 %), iron (41.85±1.36 mg/kg), zinc (48.55±4.33 mg/kg), manganese (390, 70±181.57 mg/kg), cobalt (0.82±0.19 mg/kg), molybdenum (6.80±0.67 mg/kg), which are concentrated to a greater extent in the core. The shell contains calcium (0.35±0.02 %), sodium (0.240±0.006 %), chromium (0.329±0.049 mg/kg), lead (0.60±0.04 mg/kg), cadmium (0.061 ±0.003 mg/kg), arsenic (0.024±0.002) higher than in the core. The separation of lupine grain into core and shell during deep processing can be used to increase or decrease the concentration of chemical elements. The range of variations in the content of chemical elements increases with increasing their concentration. In the analyzed samples, the content of lead, cadmium, arsenic and mercury is less than the maximum permissible values for white lupine grain used in feed. The data obtained are important for use in the production of compound feeds, protein concentrates and for determining standards for the content of chemical elements in white lupine grain and its parts as statistical materials when drawing up feeding programs for farm animals, poultry, and fish.
