Textbook Question
Chapter 3, Problem 3.15PS
Shortening. A popular brand of shortening has a label on the can that identifies the product as “partially hydrogenated soybean oil, palm oil, and cottonseed oil.”
- (a) What does the process of partial hydrogenation accomplish chemically?
- (b) What did the product in the can look like before it was partially hydrogenated?
- (c) What is the physical effect of partial hydrogenation?
- (d) Why would it be misleading to say that the shortening is “made from 100% polyunsaturated oils”?
