Years ago, whey was considered human food, but now the dairy sells it very cheaply as animal feed to avoid disposal costs. Recently, University of California-Davis researchers developed a process whereby whey can be used as a main ingredient in a plastic-like film that can be used to coat foods to keep them fresh.
a)Describe main products and by-products. How are they similar, and how are they different?
b)Under Daisy's current practices, would whey be considered a main product or a by-product? Explain.
c)With the new developments for whey, would you expect any changes in your classification in part (c)? Explain.
d)Describe several uncertainties that might arise when classifying products as main products versus by-products.
