A fully cooked food-aid product called Instant Corn Soy Blend that supplements meals, particularly for young, has been developed by U.S. Department of Agriculture (USDA) scientists.
The work was led by food technologist Charles Onwulata at the Agricultural Research Service (ARS) Dairy Processing and Products Research Unit at the agency's Eastern Regional Research Center (ERRC) in Wyndmoor, Pa.
Onwulata worked with a team of USDA scientists, program managers, policy administrators and international aid agencies for more than a decade while developing the new emergency aid meal.
Onwulata developed the new food product using the same type of machines that are used to make fully cooked puffed snacks and cereals.
The extrusion technology, used to make Instant Corn Soy Blend, cooks food completely in a short period of time under high heat and high pressure.
The crunchy, fully cooked product exits the extruder through an opening at the end of the machine in less than two minutes.
The resulting Instant Corn Soy Blend is then crushed and milled to form the ration.
The ARS technology significantly enhances the uniform distribution of added vitamins and minerals in a supplemental food ration that can be used for overseas delivery for mass feeding of young children and others.
