Dr. Amihud Kramer, 68, a professor-emeritus at the University of Maryland and an authority on food production, processing and quality control, died at Suburban Hospital Tuesday following a heart attack.
Dr. Kramer, who was born in Austria, grew up in Baltimore. He earned bachelor's, master's and doctoral degrees at Maryland, where he began teaching in the Department of Horticulture in 1942. He was named a professor-emeritus in 1980.
Despite his formal retirement from the university, he was engaged in full-time research for the Maryland Agriculture Experiment Station at College Park at the time of his death.
Dr. Kramer was internationally known for research and development of food processing procedures such as "GASPAK," a new method still under study designed to preserve raw or partially processed food in a more energy-efficent manner than canning or freezing.
He also was credited with inventing a number of instruments and procedures widely used in the food industry, including the shear press, an instrument used throughout the world to measure the maturity of vegetables and the texture of food products.
He once helped revise the nutritional tables used by the U.S. armed forces. He was an adviser to a number of foreign governments on the development of their food industries, including Israel, Egypt, Brazil, South Korea, Iran, Portugal and Ghana. He also was the science adviser to the Refrigeration Research Foundation.
Dr. Kramer, who lived in Bethesda, was the author of several books on quality control in the food industry and of more than 400 publications in scientific and trade journals. He was a member of the American Academy of Sciences, a fellow of the Institute of Food Technologists and a recipient of its Nicholas Appert Medal, and a member of the Cosmos Club.
Survivors include his wife, Diana, of Bethesda; two sons, Dr. John B. Kramer of San Jose, Calif., and Dr. Marc S. Kramer of Boston; a sister, Shoshana Puder of Tel Aviv, Israel, and a grandchild.
The family suggests that expressions of sympathy be in the form of contributions to the United Jewish Appeal.
