In the early 1970s, sweeteners such as cyclamate and saccharin were gradually decreased or removed from a variant formulation of Coca-Cola. Consequently, use of stevia as an alternative began in Japan, with the aqueous extract of the leaves yielding purified steviosides developed as sweeteners. The first commercial "Stevia" sweetener in Japan was produced by the Japanese firm Morita Kagaku Kogyo Co., Ltd. in 1971. The Japanese have been using stevia in food products and soft drinks, (including Coca-Cola), and for table use. In 2006, Japan consumed more stevia than any other country, with stevia accounting for 40% of the sweetener market.
