other processing problems include both the measurement and forecasting of time-temperature processing-a subject of considerable mathematical complexity and the object of many years of research. A constantly appearing problem centers about the retention of essential nutrients and other qualities in thermally processed foods, factors which affective the competitive character of the preserved foods market. There are a number of other processing problems which are discussed a bit later as specific operations are introduced Evident of continuing research, possibly accelerated during the past decade or so, in thermal processing of foods are the four Food Technology Industrial Achievement Awards(Institute of Food Technologists) which relate to this field. In 1966, Swift& Company and the Carnation Company were joint recipients of the award for the devel- opment and commercialization of the Flash 18 canning process, designed to substantially shorten the processing time and improve the quality of foods packed in institu- tional-size cans. A No. 10 can of beef stroganoff, for example, required a 4- to 6-hour span for a normal retort process, whereas the Flash 18 process required only about one-quarter hour. This is a high-temperature, short-time process in which preheated food is filled at sterilizing temperature into a precleaned can and sealed. The can and its contents are then held at high temperature for a short time to complete the sterilization of both the container and the product prior to chilling
