Ajinomoto

Ajinomoto Co., Inc. is a Japanese multinational company best known for seasonings and food ingredients, including monosodium glutamate (MSG). The company name derives from the flagship seasoning Ajinomoto, whose name in Japanese means “essence of taste.” It arose from the work of Kikunae Ikeda, who in 1908 identified the savory flavor in kombu and sought to commercialize it, leading to the founding of the Ajinomoto Company in 1909.

Over the decades Ajinomoto expanded from MSG into a broad range of seasonings, amino acids, and other food ingredients, as well as pharmaceuticals and specialty chemicals. It operates worldwide, with manufacturing and sales networks across Asia, the Americas, Europe, and Africa. Its product line includes Aji-no-moto MSG seasonings, Hon-dashi dashi products, and various protein and flavor enhancers, as well as corn-based and soy-based ingredients used in processed foods.

Beyond consumer seasonings, the company develops amino acid products for nutrition, feed, and industrial uses, including lysine and glutamate derivatives, and undertakes research in food science, fermentation, and biotechnology.

Regulatory status: Monosodium glutamate is widely recognized as safe by major health authorities when consumed in typical amounts. Some individuals report sensitivity to MSG, but scientific reviews have found no consistent adverse effects at usual intake levels.
