Food giant HJ Heinz is set to sell its packaged frozen dim sum business Long Fong to China-based frozen food manufacturer Sanquan Foods for an undisclosed amount. The move is part of Heinz’s strategy to de- emphasize non-core frozen food businesses outside the US. Sanquan Foods has signed the acquisition deal with Heinz’s subsidiaries – Country Ford Development and Heinz (China) Investment. Sanquan Foods is involved in the production, distribution, and export of frozen food products made of wheat flour and rice in China. Its products include quick-frozen glutinous rice balls, boiled dumplings, rice dumplings, and flour pastries.
