Content of inorganic elements in snails meat

Abstract

Currently, there are several classifications of inorganic elements, although each has its own advantages and disadvantages. The most studied group is macroelements, because they have a significant spread in the body and serve as a function of structural elements. The trace elements perform their functions, being part of the biologically active substances, which makes it difficult to study them, since the same element, depending on the form, can have a toxic effect or be vital. The macroelements include: K, Ca, Mg, Na, S, P, Cl. The trace elements are distributed as follows: Al, B, Br, V, I, Li, Si, As, Rb, Se, F, Sr and heavy metals, namely Zn, Cr, Ge, Fe, Cd, Co, Cu, Mn, Mo, Sn, Ni, Pb. Macroelements are contained in our body in a significant amount (more than 0.01% of the body weight, in other words, their content in the body of an adult is measured in grams and even in kilograms). The trace elements are involved in all processes of life and are the catalysts of biochemical reactions. Their daily intake is less than 200 mg, and they are contained in the body in small doses (less than 0.001% of body weight). The article presents the results of our own research on the content of inorganic elements in the meat of snails of various species Helix pomatia, Helix aspersa maxima and Helix aspersa muller. It is established that fresh meat of Helix aspersa maxima snails contains the least amount of heavy metals and the highest amount of selenium. Of the 12 inorganic elements that we studied in meat of snails from trace elements, Bromus is most often kept by Helix aspersa muller snails and is 1.91 ± 0.23 mg, Selenium and Manganese from Helix aspersa maxima snails are 0.32 ± 0.01mg and 29.29 ± 0.27 respectively. In the case of heavy metals in the meat of Helix aspersa maxima, there was no evidence of flatulence at all, and the most commonly found zinc in this specimen was 27.64 ± 0.22 mg in accordance. The calcium is the most enriched meat of Snails Helix pomatia and is 12571.25 ± 304.51 mg. As for the vital calcium macroelement, most of all it enriched the meat of the grape snail Helix pomatia. Based on the foregoing, it can be concluded that the fresh meat of Helix aspersa maxima snails contains the least amount of heavy metals and can be successfully used in the relevant industries, and especially in the food industry.
