Symposium: Dairy Foods and Imitations in Nutrition and Markets¹

Department of Food Science, University of Wisconsin, Madison 53706

ABSTRACT

I wish first to present a background for your consideration. The history of man might well be evaluated in terms of the changes in the world in which he lives. He found it convenient to abandon the nomad way of life, and to adapt or domesticate plants and animals for food; he has been creative for food, fiber, and comfort. Perhaps in their time, some of the changes were fully as dramatic, in effect, as some which we now observe.

The wheel enabled a change in conveyances and transmission of power: chariots, buggies, trains, tractors, autos, and airplanes. Trails to freeways. The sequence in defense (or offense) could be noted in the pit, snare, sling, blowgun, bow and arrow, crossbow, ... to the missile. Economists have rated the use of various fuels: wood, coal, fossil, hydraulic and nuclear energy. The homemaker adapted for cookery, containers of clay, glass, copper, iron, aluminum, and steel; and for her clothes, jute, silk, linen, cotton, nylon, and dacron.

¹ Presented at the Sixty-fourth Annual Meeting of the American Dairy Science Association, University of Minnesota, June, 1969.
