Food Science: An Old but New Subject
What is Food Science? Food science is the study of the nature
of food, the causes of deterioration, the principles underlying food processing, and the improvement of foods for consumers
It focuses on what happens to foods before you eat them
What is Food Science? Also address
nutrition, or the study of food components and their use by the body to sustain life
It began to evolve when technology moved food preparation from the home to the factory
Early Food Discoveries How did people obtain food 100’s of
years ago? Civilizations formed where water, game,
and land were abundant
Early Food Discoveries Food, preparation techniques, and
preservation methods were discovered through: trial and error (ex: drying grains) by accident (ex: cheese)
Earliest forms of food processing include: drying, salting, and smoking
Industrial Revolution What happened during the industrial
revolution? How would this affect food?
Industrial Revolution Began to grasp the science behind
many food products Ex: bacteria’s effect on food spoilage and
human health As a result, the canning process was
invented Mass production methods began in the
food industry
Industrial Revolution Machinery for farming increased food
supply Convenience items developed for
military Consumers initially avoided these items WWII caused many women to enter
workforce = less time for food preparation
Government Regulations Early regulations were formed due to
adulteration of food, or lowering quality and safety of a product ground pepper (gravel, leaves, twigs) vinegar (sulfuric acid) milk (chalk, starch, borax) sugar (sand and dust)
Government Regulations USDA (US Department of Agriculture)
developed to oversee food production and agricultural research
Now the USDA Oversees meat, poultry, and processed
egg products Inspects processing plants Develops dietary guidelines Regulates organic foods
Government Regulations FDA (Food and Drug Administration)
Creates food safety and wholesomeness standards
Food labeling guidelines Approves food additives
Most Important Milestone Individually, share with your group what
milestone you believe was most influential/beneficial to our country
AS A TABLE, choose ONE milestone you can agree on as the most important milestone. Be ready to defend your answer.
Contributions of Food Scientists:Expanded Food SupplyTo combat hunger: Develop safe, tasty, nutritious, low-cost foods
Ex: incaparina – cereal that contains 28% protein Develop new production methods
Hydroponic crops – grown with roots suspended in liquid nutrient solutions
Biotechnology – alters organism to create new or improved products crops altered to resist insects Herbicides kill weeds without damaging crops
Contributions of Food Scientists:New Food Products Develop foods for special needs such as
armed forces, sports, and health conditions Developed food analogs, natural or
manufactured substances used in place of food or food components Vegetable proteins that look and taste like
meat Splenda Non-dairy creamer
Contributions of Food Scientists:New Food Products
What new foods have come out in the past year??
Use the iPads or your BYOT to research. Submit answers to: https://todaysmeet.com/andreskefsn
Contributions of Food Scientists:New Processing Techniques Changing raw products into processed
foods Ex: blanching
Dehydrating food products and special packaging techniques Ex: NASA
Teflon coating
Start in Food Science As we conduct science experiments over
the semester, data collection will be vital in analyzing and reporting results.
Complete Activity 1A-1C
Benefits of Food Science Problem-solve how to improve our
country and the world Be part of our future developments Make the choices necessary to keep
yourself and those around you healthy Analyze food products and food labels Over HALF of the world’s jobs are linked
to food in some way
