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?
