Calcium plays a significant role in the human body, since most of it is in the
skeleton and teeth, and the smaller part in the form of ions participates in blood clotting
processes, is one of the universal secondary mediators inside cells and regulates various
intracellular processes - muscle contraction, exocytosis, secretion of hormones and
neurotransmitters [11-13]. The results of our studies showed that the highest calcium
content is 448.2 mg/100 g in the biologically active supplement of kelp.
Of all the seaweeds we studied, more magnesium was found in cystoseira - 875.1
mg/100 g, respectively, in quantities 2 times more than the minimum daily need, and
therefore they can be recommended as valuable ingredients with this macroelement.
In terms of iron content, all the additives studied by us satisfy from 23 to 90% of
the daily requirement for this microelement.
High content of iodine is especially valuable, in all samples it exceeds the daily
norm, human body needs this microelement for normal functioning of the thyroid
gland. Scientists have studied that iodine deficiency leads to a decrease in the
intellectual potential of a significant part of the population. Studies conducted in recent
years in different countries of the world have shown that the average indices of
intellectual development in regions with a pronounced iodine deficiency are 10-15%
lower than in regions where there is no iodine deficiency.
Deficiency of selenium in the diet of the population is the second most important
medico-social problem in Ukraine after iodine deficiency, as the chronic shortage of
selenium in the body is a dangerous factor in the deterioration of health.
The greatest amount of selenium is found in spirulina seaweed 7.2±1.3.
Safety indicators are one of the most important criteria for assessing raw materials
for food technology. The results of seaweed studies for presence of toxic elements are
given in Table 12.
