The present investigation aimed to assess chemical monosodium glutamate as flavoring agent in processed hen meat products. One hundred random of processed hen meat samples were estimated. The highest concentration mean± SE chemical Food additive Monosodium glutamate (mg/g.) as an flavoring agent was found in samples of canned hen (3.950 ± 0.51) than in hen pannae samples (1.850 ± 0.28), hen minced meat samples were the highest concentration (2.750 ± 1.05), followed by hen shawerma samples (1.730 ± 0.220), and fried hen meat samples (1.470 ± 0.850) mg/g. of chemical Food additive Monosodium glutamate as flavoring agent. So, the current estimated chemical Food additive Monosodium glutamate as flavoring agent contents in the examined processed hen samples were less than the acceptable levels stated by Egyptian Standards, FDA stated that contamination of the examined chicken meat samples in this study revealed that the amount of chemical monosodium glutamate as flavoring agent causing reactions in human being ranged from 0.500 to 3.00 mg. so a typical serving of a foodstuff with added chemical Monosodium glutamate as flavoring agent has less than 0.50 g. of Monosodium glutamate as flavoring agent. Reduction the public health hazards of exposure to these food additives as flavoring agent. The corrected and safe doses of chemical Food additive Monosodium glutamate as flavoring agent in food of human.
