Mitsubishi Corp. Japan's biggest trading house, will acquire Kirin Holdings Co. domestic food flavoring unit for 30.5 billion yen ($321 million) to expand in consumer businesses. The trader agreed to buy 81 percent of Kirin Kyowa Foods Co. in June and the rest in January 2015, Tokyo-based Mitsubishi said in a statement. The deal will expand the range of businesses at Mitsubishi's Life Sciences division. The unit, formed two years ago, focuses on seasoning, sweeteners and fermentation technology, the company said in the statement. Kirin Kyowa is at least the third food investment by Mitsubishi in as many months as the trader leads domestic rivals including Mitsui & Co. (8031) in shifting focus to health care, utilities and nutrition to counter lower profits from selling bulk commodities such as coal and iron ore.
