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

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.

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
