Emil M. Mrak, an internationally known nutritionist and food technologist who was chancellor of the University of California, Davis, from 1959 to 1969, has died.
A campus spokesman said Mrak suffered an apparent heart attack at Sacramento Metropolitan Airport Thursday night as he and his wife were returning from visiting their son in Arkansas. He was pronounced dead at University Medical Center in Sacramento. He was 85.
Mrak, who was chairman of the pesticide advisory committee for the federal Department of Health, Education and Welfare and a consumer affairs commissioner for New York City, was noted for his work on the preservation of foods and was one of the world's authorities on the biology of yeast.
He was an outspoken foe of so-called organic foods, maintaining that the word organic is meaningless and that naturally grown fruits and vegetables are often deprived of natural vitamins in their processing.
