Anticipatory Set

  • Has anyone had any dairy products today? (Milk in their cereal, ice cream, yogurt, etc.)
  • What are some other dairy products that you know of?
    • Take a few answers, make sure they understand that dairy products are produced from milk and dairy cows.

Direct Instruction

1st Learning Goal: Upon completion of this lesson students will be able to understand that dairy products extend beyond milk, cheese, ice cream, etc.

 

Content Outline
What is a Byproduct?
  • A byproduct is a secondary, or unintentional, product made during the processing or production of another product.
What are the Main Dairy Byproducts?
  • When we are processing milk, we end up with a few main byproducts:
    • Casein- a protein found in milk that contains amino acids.
    • Whey- a dilute, highly perishable greenish yellow fluid and the largest by-product of the dairy world
Casein
  • Casein has a variety of uses including:
    • Cheese making
    • paper, textile, paint, leather, rubber production
    • Special “high-clarity” casein has been used to manufacture television screens.
    • Canned tuna– Several brands of canned tuna have casein in them to enhance flavor.
    • Baby formula- its proteins and amino acids make it a nutritional addition.
    • Protein supplements are often casein based or have casein as a primary ingredient.
    • Some chewing gums even used protein from casein (trident is one example)
Whey
  • Whey was formerly a waste product during the manufacture of cheese but is now used for:
    • Cheese whey accounts for nearly 95% of total whey
    • Candy, baby food, baked goods, lactic acid (an ingredient in cake mixes), and cosmetics (makeup).
    • Dried whey and whey products are often utilized in animal feeds.
    • Whey protein based infant formulas and other nutritional products that require lactose
    • Medications and vitamins sometimes contain whey.
    • Cheese whey proteins are used to make clear film packaging materials.
    • Whey and lactose are even used to make specialty adhesives and paper coatings.

Learning Activity

Students should be provided with a paper of images (some byproducts of dairy production, others that aren’t), at the conclusion of the presentation they should write/color/circle which images are byproducts and be encouraged to list if they utilize whey or casein.

 

Assessment

Questions similar to the following should be asked:

  • What is whey?
  • What is casein?
  • What is one product you learned about that you didn’t know was a dairy byproduct before today?

 

Closing Announcements/Reminders
