Safety emphasized on mycotoxin and glyphosate in oats and oat-based beverage

Abstract

Oat (Avena sativa L.) is the most consumed cereal as whole grain with valuable healthy nutritional content worldwide, where the Brazilian ranking in South America’s first position accounts for 95% in national production. The occurrence of mycotoxin as well as glyphosate residues was evaluated in 615 post-hulled oat grain from 2019 to 2021 crop. The reliability of analytical analysis was standardized by periodical inter-laboratory validation and participation in proficiency tests. It was detected deoxynivalenol (DON), zearalenone (ZEN) and aflatoxins (AFs) in 82%, 52%, and 61% of the samples, respectively. Glyphosate was detected in 48% of the samples, in which 11% presented glyphosate level higher than the Brazilian legal limit. Although several countries have strict control regulations, mycotoxins and pesticide contamination still occurred from time to time. Such understanding about contamination in food byproducts basis will be essential regarding development of new innovative vegetable-based products. Incentivize the local typically established dry cereal grain agroindustry intended for further advance thorough application of reliable assembled knowledge in improving derived foodstuffs.
