About Us


What we do at Kappa

The Stern family has been in the fats and oils industry for over 5 generations. After several successful ventures, Ralph Stern saw an opportunity to use his many years of experience in the industry to open a plant that could turn low cost by-products into a variety of desirable finished oils. Founded in 1969, Kappa Products became Chicago's first and oldest family owned animal and vegetable oil processing plant. One of only a handful of companies nationwide that provide these highly specialized services, Kappa Products stands out for superior quality, service, and product integrity. Serving customers from across the United States and around the World, Kappa Products is centrally located in Chicago, Illinois with easy access to five major expressways and all U.S. and Canadian rail lines. 


A short fat history


For more than 100 years, fats and oils have been used in the feed rations of domestic animals raised for human consumption.  Gradually, the industry has come to understand the nutritional beneficial effects of fat as research studies have demonstrated how its higher caloric value boosts the efficacy of feed conversion.  Of all the food types, fat contains the highest energy loading in terms of calories per unit of weight.



Which fat works the best?


Today to achieve these proven beneficial effects on feed conversion, the industry uses feed grade fats from a great variety of sources.  In fact, our industry uses billions of pounds of these fats annually in the United States; in the feed rations of turkeys, pigs, broilers, laying hens, cattle and other species of human food chain animals.


If you are like most of today’s feed mills, you want consistent quality and dependable service for all feed components.  And because fat plays such a critical role in animal nutrition, it’s especially important that the fat you use meets the quality demands of uniformity, consistency, high energy while meeting all FDA guidelines.  

Recycling at its best!
