Lecture 1 Flashcards
Food Science is a science that consists of
the continuum from the farm to the consumer
What was the turning point in the food industry
World war 2
In the 1950’s
marketing of food for convince of processed food
What did food marketing target
housewifes
Industry built up what idea
that life was a constant state of panic
Why WW2
made food for distribution to the troops
needed to be safe
needed to be healthy
they needed calories
Why do people buy food
taste, appearance
Our health depends upon the
nutritional quality, safety, and balance of foods we eat
Technology makes possible the staggering variety and availability of
frozen, baked, dried, fermented, canned, refrigerated, packaged and fresh foods.
Part of the technological equatin is related to the numberous traditional non-food substances that are formulated into manufactured foods as processing aids and increased the shelf stability and safety of many foods. They are
emulsifiers
artificial sweeteners
dough conditioners
What is food science
food science is the discipline in which biology, physical sciences and engineering are used to study
the nature of foods, the causes of their deterioration
and the principles underlying food processing
What is food technology
application of food science to selection preservation, processing, packaging, distribution, and use of safe, nutitious and wholesome food.
Food Manufacturing
mass production of products generated from raw animal and plant matter using principles of food technology
Food Science is more than cooking and food additives it is
feeding the hungry with dried milk, fish flour, single cell protein (yeast)
it is preventing food borne illness
and product development/improvement
for space travel, military rations, imitation meats, non-caloric sweeteners, reduced fat
What are some of the dimensions of food science and technology
food processing and manufacture food preservation and packaging food wholesomeness and safety food quality evaluation food distribution consumer food preparation use
What are other components of food science
growing and harvesting packaging marketing and retail food service consumer services regulatory issues
Food science is an interdisciplinary field of study. who all is involved
microbiology chemistry biology physics nutrition engineering
Biology and food science
foods are living organisms
Food scientist must understand how raw food sources are organized on the cellular level
This foundation is needed to understand how changes thatoccur during processing ,storage
Important in food safety (microbiology)
Chemistry and food science
chemistry of the atoms and molecules that make up substances their arrangement into structures and the reactions they participate in
Food scientists want to know and understand the molecular structures of these food components and to study changes to them that might affect quality.
Physics and food science
physics is the study of matter and energy and is concerned with the physical changes that matter experiences under certain circumstances.
Thermodynamics, or the study of heat and other forms of energy, seeks to explain the properties of matter such as the solid or liquid state of food.
Engineering and food science
applies to food processing
The unit operations of the food industry invoke engineering principles that are applied to food processing (heat tranfser, refrigeration, freezing, evaportation , drying)
Wide Variety of foods available
fresh produce meats and seafood dairy frozen food and entrees refrigerated foods and beverages deli foods
Food scientist do not work in isolation
research and development advertising and merchandising production and manufacturing sales and marketing regulatory issues environmental issues
How did the food industry begin
need for safe food supply to feed the worlds population
Europe-mid 1700
Started with simple machine
Development of modern organized food industry
Technology had a major impact on thedevelopment fo the food industry
Careers in food science
largest employer in theUS 17 percent of US is employed by the food industry Food technologis foodmicrobiologist technical sales sensory specialist process specialist bakery scientist
Food Industry is
Extremely large employs lots of people raw material production food processing transportation wholesalers retail and food service
