10

what replaced the glass jar?

- the glass jar was soon replaced by the tin can in which awaited the invention of the can opener 1855

11

what was ammonia compression and who invented it?

in 1859, ammonia compression was invented by Ferdinand Carre
- this invention allowed year round freezing of food, in 1920's the use of CFC's was a safer alternative to ammonia
- allowed the refrigerator to enter the home

12

How did Louis Pasteur contribute to the food industry?

he developed pasteurization, which became the basis for all thermal processing
- showed that bacteria caused food-borne disease and heat killed bacteria

13

What is Adulteration?

ass food production lead to mass ADULTERATION of food products
- ground pepper contained ravel and twigs
- vinegar was diluted with sulfuric acid
- milk had added water and other substances

14

what is the USDA (The U.S Department of Agriculture)?

had authority to oversee food production and agricultural research (regulates organic foods)
- Harvey Wiley a USDA chemist fought to eliminate misnamed and adulterated foods, this lead to the creation of the FDA

15

what is the FDA (Food and Drug Administration) ?

regulates 80% of food supply
- Pure Foods and Drugs Act of 1906: Prohibits interstate commerce of misbranded and adulterated foods, drinks and drugs
Food, Drug and Cosmetic Act of 1983: expands the FDA authority to cover cosmetics and establish regulations and guidelines for the food industry

24

What is Food Labelling?

FDA, USDA (USA) and CIFA (Canada) laws established to protect food from "farm to table", or from growth until the reach of the consumer

25

What are food scientists?

know the biology and chemistry of foods and the processes used to improve and preserve them

26

What is Expanded Food Supply and what are some forms of this?

improved grain production to combat hunger
- Hydroponic Crops
- Biotechnology

27

What are Hydroponic Crops?

are grown with their roots suspended in nutrient liquids solutions

28

What is Biotechnology?

is used to lower productions costs and increase crop yields
