READY OR NOT

1
READY OR NOT

• Objective - Examine the impact of technological
  advances to food production, availability,
  preparation, and nutrition

2
Terms of Endearment

• Record these main ideas in your notes
• Science the study of the physical world at all
  levels, including the findings and knowledge that
  result form such studies
• Technology the practical application of
  scientific knowledge. Science in Action!
• Food Science the scientific study of food and
  its preparation

3
Manufactured Foods

• 1.Analogs foods made to imitate actual foods.
  Often TSP (Textured soy protein) is used to
  create meatless meats.

4
Manufactured Foods cont

• 2. Formed Products food made from an
  inexpensive source and processed to imitate a
  more expensive food. (example white fish
  flavored and shaped to resemble crab meat.

5
Manufactured Foods cont

• 3. Egg substitute made from egg white

6
Technology Advances in Packaging

• Modified Atmosphere Packaging (MAP)
• A mixture of carbon dioxide, oxygen, and nitrogen
  is insterted into the packagebefore sealing to
  slow bacterial growth.

7
Technology Advances in Packaging

• Aseptic Packages
• consist of layers of plastic, paperboard, and
  aluminum foil. The food and package are
  sterilized separately and rapidly. The food is
  then packaged under sterile conditions.

8
Technology Advances in Packaging

• Retort Packaging
• Flexible packages also made of aluminum foil and
  plastic film. Food is placed in the pouch and
  both are heat processed. Pouches can be used to
  store food after opening and some can be
  microwaved.

9
Technology Advances in Packaging

• Slide zippers
• Ready to cook vegie packaging
• Squeeze tubes

10
Technology Advances in Transportation

• Computer controlled storage compartments for
  shipping
• Containers made with VIP (vacuum insulation
  panels), an extremely thin plastic or Styrofoam
  layer coated with a metallic film, can keep ice
  cream frozen for a week.

11
Technology Advances in Production

• Genetic Engineering
• A process whereby genes are removed from one
  organism, such as a plant, animal or
  microorganism and transferred to another one.
• Alias
• GMO Genetically Modified Organisms
• GMF Genetically Modified Foods
• Bioengineered foods

Career Close Up With one or two partners use
class resources to find the answer to your
assigned question. Keep a list of sources. Be
ready to present in 30 minutes. Can you make it
interesting?
What are the advantages of Genetic Engineering in the food chain? What are the disadvantages of Genetic Engineering in the food chain?

Food Technology Advances in Nutrition

• Enrichment replaces nutrients lost during
  processing
• Fortification adds nutrients to the food not
  normally present (vitamin D is added to milk)
• Functional foods provide additional benefits to
  improve health

16
Functional Foods CategoriesDesigner Foods /
Nutraceuticals

• Food that claims special health benefits
• Natural whole foods grapes, broccoli, oats are
  examples of foods that appear to have certain
  health advantages
• Enhanced food with substances
• New foods example special margarine that lowers
  cholesterol
• Food created by science example a genetically
  engineered to contain more lycopene

17
Technology Advances in the Kitchen

• Ergonomics the study of ways to make space and
  equipment easier and more comfortable to use.
• Results in body comfort and savings of time and
  energy

18
Technology Advances in the Kitchen

• Appliances are more reliable, easier to use, and
  energy efficient.
• Smart appliances contain a computer chip that
  monitors their own workings and lets you program
  their functions.

19
Computers in the Kitchen

• Computers store recipes, create menus, and
  organize shopping lists. They can keep track of
  what in your kitchen and what you spent on it.
  Nutrition information is available. You can even
  shop on line for foods.

Food Technology Tradeoffs

• Positives

• Negatives

• More variety of foods
• More options and ease for those with disabilities

• New processes create by-products that must be
  managed
• Not all businesses can compete with tech services
• New decisions means the need to educate yourself
  constantly
