Since being involved in a scandal over tainted spinach last year, Nichirei Corp., the nation's largest maker of frozen packaged foods, has been working toward recovery by selling products that contain fewer additives than those of its rivals.

In fiscal 2002, Nichirei's annual sales of frozen packaged foods slipped 3.6 percent from a year earlier to 165.6 billion yen.
