Ajinomoto products

Monosodium glutamate

Ajinomoto’s main product, monosodium glutamate (MSG; グルタミン酸ナトリウム) seasoning, was first marketed in Japan in 1909, having been discovered and patented by Kikunae Ikeda. He found that the most important compound within seaweed broth for common use was actually a glutamate salt, which he identified with the taste umami, a word meaning 'pleasant taste' or 'savoriness'. As the simplest such salt for human consumption, the popularity of MSG helped the company rapidly expand to other countries, with Ajinomoto U.S.A., Inc. established in 1956.

Before the eventual publicity, the conglomerate was founded on Ikeda's work: it was the first to suggest that industrially purified glutamic acid salts, residues or analogues, originally found in seaweed or dried fish-based broth, might have a characteristic taste of its own. That idea was rapidly connected to the much older Japanese, culinary term of umami. This led to early adoption of MSG as a culinary agent in Japan.


Ajinomoto is the world's largest manufacturer of aspartame, sold under the trade name Aminosweet. It acquired its aspartame business in 2000 from Monsanto for US$67 million.[5]


Ajinomoto supplies the amino acid L-Glutamine.


Lysine price-fixing (1990s)

Ajinomoto was a member of the Lysine price fixing cartel in the mid-1990s. Along with Kyowa Hakko Kogyo, and Sewon America Inc., Ajinomoto settled with the United States Department of Justice Antitrust Division in September 1996. Each firm and one executive from each pleaded guilty as part of a plea bargain to aid in further investigation. Their cooperation led to Archer Daniels Midland settling charges with the US Government in October 1996 for $100 million, a record antitrust fine at the time.[6] The cartel had been able to raise Lysine prices 70% within their first six months of cooperation.[7]

2000 to 2008

By mid-2000, Ajinomoto's acquisition of NutraSweet and 'Euro-Aspartame' from Monsanto had been completed.[5]

In early 2001, Ajinomoto was involved in a scandal in majority-Muslim Indonesia when it emerged that a pork-based enzyme had been used in its production of MSG.[8]

In January 2006, the company bought the cooking sauce and condiments manufacturer Amoy Food from the French dairy product company Groupe Danone, which had run the division as the "Amoy Asian food unit".[9] At the time of the acquisition, Ajinomoto was the largest Japanese maker of seasonings.[9]

Lawsuits against Asda (2008–2010)

In 2008, Ajinomoto sued British supermarket chain Asda, part of Wal-Mart, for a malicious falsehood action concerning its aspartame product when the chemical was listed as excluded from the chain's product line along with other "nasties".[10] In July 2009, a British court found in favour of Asda.[11] In June 2010, an appeal court reversed the decision, allowing Ajinomoto to pursue a case against Asda to protect aspartame's reputation.[12] At that time, Asda said that it would continue to use the term "no nasties" on its own-label products,[13] however, the suit was settled out of court in 2011 after Asda removed references to aspartame from its packaging.[14]

2010 to present

In late 2012, the Company sold its Calpis beverage unit to Asahi Breweries for US$1.5 billion.[15]

In 2013, the Company acquired the
