Soprole or Sociedad de Productores de Leche is a Chilean maker of dairy products. Under the Soprole brand, the company markets yogurt, milk, pastries, and butter.
Soprole was created in 1948, initially as a milk
producer. In the 1970s, it diversified its production into more value-added products like juices, pastries and yogurt. Juan Luis Undurraga Aninat
, one of the founders, acquired the shares of other investors allowing him to control more than 40 percent of the company. In 1986, The New Zealand Dairy Board, now part of Fonterra
, acquired more than 50 percent of Soprole's shares, giving it majority control. That same year, Juan Luis Undurraga Aninat transferred his shares of the company to create the Fundación Isabel Aninat. Under the control of the New Zealand Dairy Board, Soprole bought out some of its competitors like Lácteos Pirque
in 1994 and Dos Álamos
in 1997. Today, 76 percent of the Chilean dairy market is controlled by four companies: Nestlé
