“…This finding was in an agreement with previously reported data on the dynamic changes of elemental profile during germination in different plant species. Studies showed increases in most of the mineral elements during germination in cereals like buckwheat and wheat sprout [15,29], sunflower sprouts [30], Cruciferae sprouts [31] and soybean sprouts [15,32]. The differences in mineral content may be due to the loss in dry weight and increase in the proportion of inorganic matter and decrease in organic nutrient during sprouting, and hence can be treated as apparent [14].…”

Considering the growing interest in functional foods, the identification of the individual species of elements is of great importance in understanding specific nutraceutical properties. The present study aims to compare the dynamic of the elemental content (K, Na, Ca, Mg, Fe, Cu, Zn, Mn, Ni, and Se), total polyphenols, and antioxidant activity of Trifolium pratense L. and Medicago sativa L. sprouts in different germination stages. The elemental profile was established by atomic absorption spectroscopy after the microwave acid digestion of the samples, while total polyphenols and anti-radical activity were evaluated by UV-Vis spectroscopic methods. Phenolic compounds and anti-radical activity of both alfalfa and red clover sprouts varied with germination stages. Germination can significantly increase the anti-radical activity in the first 3 days of germination, followed by a decline in the following days. An increase in total polyphenols was noticed, starting from the second day of germination in both plant species. There were significant (p < 0.05) differences for Ca, Na, Fe, K, Zn, and Mg contents among the sprouts, depending on the germination stage and plant species. The calcium contents of alfalfa ranged between 200.74 µg/g DW (raw seeds) and 2765.31 µg/g DW (sprouted), while in red clover between 250.83 µg/g DW and 601.59 µg/g DW. Maximum selenium content in alfalfa sprouts, reached in the 3rd day of germination (11.42 µg/g DW), exceeded the maximum value measured in red clover (9.42 µg/g DW). The data were subject to statistical processing using analysis of variance (ANOVA), multivariate analysis (PCA) and hierarchical clustering analysis (HCA).

The article is aimed at unifying technological approaches to production of functional drinks from hemp and soybean seeds. We studied the change in chemical states of calcium and phosphorus during swelling and germination, as one of the factors that enable the osmoregulation of the protein complex and increase stability of plant dispersions from bioactivated seeds. Seeds at rest, swelling seeds and germinating seeds and aqueous dispersions based on them were studied. The sources of insoluble and soluble forms of macronutrients in the cellular structures of bioactivated seeds were studied. It has been established that swelling forms of calcium included in the general metabolism become mobile. A further increase in calcium content in the aqueous dispersion up to 98.5% is accompanied by a rapid increase in conditionally soluble calcium (14.6 times) and an increase in stability of the system. Calcium metabolism in seeds is accompanied by changes in the phosphorus-salt composition. Within 48 hours, with an insignificant (4.7%) decrease in total phosphorus, an increase in soluble inorganic phosphorus (67.5%) and a decrease in organic phosphorus (51.9%) were observed. The appearance of inorganic phosphates and calcium ions in cell juice can be associated with the hydrolysis of phytin. In such forms, digestibility of phosphorus and calcium increases. Similar results were obtained for dispersions from germinating soybean seeds.
