Investigation of germinated crops elemental composition

The introduction of the crops germination stage allows increasing their nutritional value by increasing the amount of minerals, vitamins and amino acids, which are easily digested and have a beneficial effect on a human body. At the same time, heavy metals located on the surface of grains pose a danger to human health. When the grains swell, the water treated in various ways (magnetic, ultrasonic, etc.) is used. However, there is not enough information about changes in minerals and the toxic elements content during germination of flax seeds and buckwheat grains processed with physical methods. Therefore, in the work, we investigated the change in mineral substances and toxic elements during germination of flax seeds with the application of magnetized water and buckwheat grains - with ultrasonic treatment of tap water using mass spectrometry and atomic emission spectrometry with inductively coupled plasma. It was found out that the germinated flax seeds and buckwheat grains were characterized by different mineral contents and fewer toxic elements. The content of calcium, potassium, magnesium, phosphorus, selenium, copper, zinc increased in crops in the process of germination.
