The story
Morningstar Farms was introduced by Worthington Foods (originally part of Miles Laboratories). The frozen food line of soy-based meatless meats was introduced into supermarkets and grocery stores in the U.S. in 1975. It was widely advertised and introduced Americans to the use of soy as a base for meat analogs. Kellogg's purchased Worthington Foods from Bayer AG's North American division for $307 million in October 1999, at which point it acquired the Morningstar Farms brand. Kellogg sold Worthington in 2014 but retained the Morningstar line of products.
In 2021, Kellogg's announced it would spend $43 million to expand their Zanesville, Ohio, Morningstar Farms manufacturing plant.
