A comparative analysis of the data in Table 8 shows that the obtained results are
consistent with the literature data, and the number of all mineral elements is much
higher than the adequate level of consumption, which indicates the value of this raw
material as their source.
One of important parameters of fish raw material is the data on toxic elements
content (Table 8).

Analysis of the data in Table 8 shows that the selected fish raw material is food
safe and can be used in food production.
Characteristics of nutritional value of biologically active additives of seaweeds
are given in Table 9.
