Kraft Inc. said it agreed to buy a Quaker Oats unit.

The two companies announced that Kraft will pay $235 million for the Anderson Clayton Foods Division. The businesses in the division going to Kraft include Seven Seas salad dressing, Purity cheeses, Anderson Clayton edible oils, Chiffon margarine and Avoset food packing. Quaker bought the Anderson Clayton division last year solely to obtain the Gaines pet food business and planned from the start to sell off the other operations, said William D. Smithburg, chairman and chief executive of Quaker.
