Aflatoxins adsorption by lignin treated with sodium hydrocarbonate using technogenic raw materials.
2024
This study examines aflatoxins adsorption by lignin treated with sodium hydrocarbonate. Food safety and security issues are of great relevance in the modern world. Food safety is secured only when healthy and full-value products are in sufficient quantity and accessible for everyone. Numerous organizations worldwide along with researchers work to solve this problem and find ways to ensure food safety. Mycotoxins are one of the major challenges for food safety and security, since they contaminate products during storage and transportation. Aflatoxins, which belong to the class of mycotoxins, are acute carcinogenic, mutagenic and teratogenic toxins. They are the products of Aspergillus fungi metabolism, which grow mainly on cereal crops and nut crops. Aflatoxins are also found in milk and meat products. Toxins penetrate animal organism from contaminated cereals. This study examines aflatoxins adsorption by lignin treated with sodium hydro-carbonate. As an adsorbent a lignin treated with sodium hydrocarbonate was used. We have infected pieces of bread with Aspergillus parasiticus and Aspergillus flavus microorganisms, which generate different groups of toxins. A sample was placed along with lignin treated with sodium hydrocarbonate, and adsorption properties were studied. Using thin-layer chromatography, aflatoxins concentration and type have been identified in the specimen under investigation and in lignin. The method employed by us, is ecologically safe, technologically simple and accessible. We have studied the adsorption properties of lignin treated with sodium bicarbonate with the purpose of aflatoxin deactivation. This method is in full compliance with food safety requirements.
