  • Microwave safe containers include
  • Plastic, paper, glass
  • Define Standing Time
  • Foods continue to cook when removed from the
    microwave
  • What increases cooking and standing time?
  • Quantity and volume

7
  • For best results when cooking in a microwave
    remember too
  • A. Stir and rotate food for even cooking
  • B. Covering foods holds moisture in
  • C. Cook in round/ring container for even
    cooking
  • To prevent burns from microwaves
  • A. Lift cover or plastic away from you

    paper or
  • lid.

8
Safety Guidelines and Safe Work Habits
  • Electrical appliances
  • Use dry hands, stand on dry floor, keep away from
    water
  • Knives
  • Dull knives are more dangerous and less efficient
  • Grease Fires
  • Cover with lid, baking soda or salt,
  • Avoid flour or sugar
  • Poisonings and contamination
  • Do not mix chlorine with ammonia products
  • Store cleaning supplies away from foods

  • Calories are according to age, gender, body size,
    and activity level

24
Dietary Intake goals
  • Carbohydrates
  • 55-60 total daily calorie intake
  • Fat

25
American Diets
  • Have more fat, sugar, salt, and calories than
    recommended
  • Are lower in fiber than recommended
  • Salt and sodium are added to processed foods,
    beverages, and diet drinks
  • High consumption of salt and sodium lead to high
    blood pressure
  • Be aware of invisible fat in foods

26
Food Pyramid

  • Complex carbohydrates
  • Known as starches
  • Whole grains, cereal, dried beans, rice
  • Simple carbohydrates
  • Known a sugars

32
Fiber
  • 20-35 grams daily
  • Roughage
  • Attracts water to our intestines, and moves food
    through the intestines faster

    cancer
  • To add fiber to a recipe add bananas, berries,
    replace flour with part whole wheat flour

33
Rice and grains
  • Whole grain most nutritious bread because it
    contains the whole grain
  • White and brown bread contain only the endosperm
  • Brown rice the whole grain form of rice
  • Cooking rice covered in simmering water on low
    heat, triples in bulk
  • Long grain rice a rice that will stay dry and
    fluffy

    to the tooth

35
Quick Breads
  • Non-yeast, leavened flour based products

  • Biscuits -Corn bread -Popover

36
Water most essential nutrient
  • Carries vitamin C and B through the body

    needs
  • Needed in small amounts but are critical to
    health
  • Macro Minerals calcium, phosphorus, magnesium
  • Electrolytes sodium, potassium, chloride
  • Trace Minerals iron, iodine, flouride, zinc

39
Mineral deficiencies
  • Calcium osteoporosis bones gradually lose
    their minerals becoming weak and fragile

    count, animal products provide excellent sources
    of iron select lean types/cuts

40

  • Soft peaks
  • Stiff peaks
  • To increase storage life of eggs store in
    original carton (good for several weeks)

44
Milk
  • To prevent scorching heat at low temperature and
    constant stirring or heat in the microwave
  • Pasteurized milk heat treated to remove harmful
    organisms
  • Homogenized milk fat particles mechanically
    broken down and evenly distributed so the fat
    will not separate out
  • Types of milk
  • Reduce fat in recipes
  • Procedure for white sauce moderate temperature
    and stirring constantly
