    The article provides information about a study conducted to investigate behavioral reactions and stress tolerance in rats that were administered chemical food additives (monosodium glutamate, sodium nitrite, Ponso-4R) for different durations. In the study, experimental subgroups of laboratory rats were administered complex chemical food additives daily once orally for 1, 4, 8, 12, 16 and 20 weeks. Cognitive functions were assessed using the “Extrapolation Escape” test. The analysis of the obtained results showed that the estimated indicators at the initial stages of the experiment (up to 8 weeks) had positive dynamics, which was characterised by a reduction in the time of occurrence of reactions. After 12 weeks of introducing the complex of food additives, negative changes occurred, which were manifested by a gradual postponement of the studied indicators. The worst indicators were recorded after week 20 (significant at p<0.05. It was found that the use of a complex of chemical food additives leads to blunted reactions under conditions of acute stress, as well as impaired ability to find a way out of the acute stress situation.

    The effect of a complex of food additives on cognitive functions and the speed of conditioned reflex formation

    The article provides information about a research study conducted to establish changes in behavioral reactions of rats at different times of use of a complex of chemical food additives (monosodium glutamate, sodium nitrite, Ponceau 4R). The study was based on administering experimental laboratory rats subgroups for 1, 4, 8, 12, 16, and 20 weeks of a complex of food additives once a day orally. Cognitive function was determined by assessing the formation rate of a conditioned food-retrieval reflex in a complex maze. The assessment of the behavior of experimental animals in a complex maze showed that at the initial time of introducing a complex of food additives (up to week 8), the obtained results had positive dynamics, with values of p<0.05. All evaluated parameters had a negative trend from the 12th week of the experimental study. Significantly (p<0.05), the worst indicators were registered after the 20th week of the experimental 136 study. It was found that consumption of a complex of food additives leads to cognitive dysfunction in rats, which was characterised by impaired memory function as well as learning ability
