1. Food Science: An Old but New Subject

2. 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

3. 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

4. Early Food Discoveries
How did people obtain food 100’s of years ago?
Civilizations formed where water, game, and land were abundant

5. 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

6. Industrial Revolution
What happened during the industrial revolution?
How would this affect food?

7. 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
Canning process was invented in France
1st US canning plant was opened in New York in 1812

8. 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
Steam power machines like plows, reapers, and threshers were able to do work in a few minutes what used to take all day
Baking powder mass produced 1856
Commercial yeast available 1868
Self-rising flour marketed in 1890
Pillsbury and Campbell’s were founded in 1869

9. 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)
Borax is sodium borate, white powdery, found is detergent

10. 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

11. Government Regulations
FDA (Food and Drug Administration)
Creates food safety and wholesomeness standards
Food labeling guidelines
Approves food additives

12. 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.

13. Contributions of Food Scientists: Expanded Food Supply
To 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

14. 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

15. 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:

16. 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
We now know blanching increases nutrient content
Nasa has their own group of food scientists that led to vacuum packaging, teflon coating, and freezer to oven cookware.

17. 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

18. 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
