Is there a difference between Mrs Chicken Essence and Mai Sha Chicken Essence?

Taitai Le Chicken Essence is different from Mai Sha Chicken Essence. Relevant information shows that Taitai Le Chicken is produced by Shanghai Taitai Le Food Co., Ltd., and Jingsha Maiji Essence is produced by Sichuan Guosha Industrial Co., Ltd., with different producing areas and different production techniques. Chicken essence is prepared from monosodium glutamate, edible salt, chicken bone powder or its concentrated extract, disodium flavor nucleotide and other auxiliary materials, with or without spices and/or flavoring agents, through mixing and drying. Compound seasoning of chicken flavor and fragrance is more than twice as fresh as sodium glutamate. Because chicken essence contains odorous nucleotides as flavoring agent, it has refreshing effect and its purity is lower than that of monosodium glutamate.
