Evaluation of the sorption properties of shungite in relation to mycotoxins

Abstract

The problem of mycotoxicosis is relevant for many livestock, pig and poultry farms, as well as for ensuring food security. In most cases, mycotoxin poisoning can take place in a latent form and manifest itself in the form of a decrease in productivity and growth retardation of animals, cicatricial digestion disorders, immunosuppression, etc. Therefore, the requirements of regulatory and technical documents clearly regulate the maximum allowable value of these contaminants in both feed and food raw materials. One of the modern ways to combat mycotoxins is the introduction of sorbents that bind to mycotoxins and prevent their absorption in the gastrointestinal tract. There are a large number of sorbents on the market. The range of complex feed additives of sorption action is expanding, therefore, it is of interest to determine their effectiveness. One of these sorbents is a natural mineral - shungite - an intermediate product between amorphous carbon and crystalline graphite, containing carbon (30%), quartz (45%) and silicate micas (20%). The purpose of the work is to study and evaluate the sorption capacity of shungite in relation to mycotoxins: aflatoxin B1, deoxynivalenol, zearalenone.
Methods. The object of the study were samples of crushed shungite. In the process of work, experimental studies and evaluation of the sorption properties of shungite in vitro were carried out using the high performance liquid chromatography (HPLC) method.
Results. When calculating and analyzing the sorption capacity of the mineral, high sorption properties with respect to mycotoxins were established, namely, aflatoxin B1 is sorbed by shungite by 99.2%, deoxynivalenol - by 99.9%, zearalenone - 99.8%, which makes it possible to recommend the mineral for use in veterinary medicine as a feed additive for the prevention of mycotoxicoses.
