1. What is Food Science?
Chapter 1

2. History of Food Science
Food Science = is the study of producing, processing, preparing, evaluating, and using food.
1696, Sir Francis Bacon wanted to see how stuffing the bird with snow conserved the meat – as a result from the experiment Bacon developed bronchitis and died soon
1st food science ”textbook” were cookbooks
A recipe, after all is based on facts that cooks have learned by trial and error
1896 – Boston Cooking School Cook Book was thought to awaken food knowledge
George Washington Carver help develop over 100 products from peanuts, pecans, and sweet potatoes
Early 1900’s advances in technology gave rise to commercial food processing
1925 Clarence Birdseye helped the frozen foods industry get started with a refined method for quickly freezing fish

3. Food Science Today
Like other science, food science has advanced rapidly in recent decades
The diet-conscious can not choose from many fat-free products, including ice cream and cookies.
Poultry producers can spray chicken with a substance that the birds consume as they clean it from their feathers.
This substance then kills disease causing germs in the chickens’ intestines

4. Food Production
Food Chain = through this process, matter and energy transfer between organisms as food
First, seeds are planted and grown
Animals eat the plants, and people eat both
With nourishment, people plant more seeds, and the process begins again
Food production has developed many techniques for raising crops and animals of food.

5. Food Production Continued
Biotechnology = scientist use the tools of modern genetics in the age-old process of improving plants, animals, and microorganisms for food production.
Modern biotechnology allows food producers to do the same, but with greater understanding and selectivity
Through biotechnology, scientists improve agricultural products by enhancing or eliminating traits that a plant or animal inherits
Ex. in one achievement, a way to turn on a plant’s natural defense against disease and insects was found, producing an alternative chemical pesticide

6. Food Production Continued
Food scientists involved in productions typically specialize in one food group and its components ex fish, cereal grains etc.
Microbiologists – research molds, bacteria and other organisms
Supply and Demand affects pricing – why?

7. Food Processing and Food Preparation
Food that has been produced and puts it through a multitude of steps to create a final marketable result.
Developing a more economical processing methods
Work generally takes place in a lab, working with other specialist ex. engineers, microbiologists, flavor experts etc.
Quality control is used on a daily basis, to make sure final product meets government, industry, and company standards
Nutrition information on a food label comes from scientists who test food for nutrient content
Determining yield, times, temperatures and other factors result in multiple tests to make sure the consumer receives the best product possible.

8. Evaluation and Utilization of Food
Food scientist work with other experts to refine a product’s taste, texture, appearance, and other qualities.
Try varying ingredients and preparation methods to design the most pleasing and profitable food product.
Food design consultant might suggest changing the sweetener, while a flavor chemist will be able to chemically alter the product and affect its taste. – cost and ease of production determines a big factor
Consumers deplete our natural recources, alternative resources are being developed.

9. Nutrition Science & Science in Real Life
Scientists deal with atoms, molecules and cells, from their research comes new information and developments
Questions –
Why do fresh bananas turn brown?
What do you put on bananas to prevent them from turning brown?
What other food turns brown when you slice in to them?
