Boston was part of the New England corner of triangular trade, receiving sugar from the Caribbean and refining it into rum and molasses, partly for export to Europe. Later, confectionery manufacturing would become another refined product made from similar raw materials. Related companies with facilities in Boston included the Boston Sugar Refinery (inventors of granulated sugar), Domino Sugar, the Purity Distilling Company, Necco, Schrafft's, Squirrel Brands (as the predecessor Austin T. Merrill Company of Roxbury) American Nut and Chocolate (1927) This legacy continued into the 20th century; by 1950, there were 140 candy companies in Boston. (Others were located in and some moved to nearby Cambridge.) The Boston Fruit Company began importing tropical fruit from the Caribbean in 1885; it is a predecessor of United Fruit Company and Chiquita Brands International.
