Fatty acids in germ contribute to what issue, leading to their removal?

• A. Off-flavors and rancidity
• B. Improved Shelf Life
• C. Increase in sweetness
• D. Decrease in fat content

Answer: (A)

Fatty acids in the germ are prone to oxidation and hydrolysis, especially when exposed to air, light, or heat. Lipids in the germ can be broken down by enzymes like lipase, releasing free fatty acids, which and their oxidation products create off-flavors and rancid odors. Removing the germ lowers the total fat and reduces the activity of those lipids, improving stability and extending shelf life. That’s why this issue is described as off-flavors and rancidity, leading to their removal. The other choices don’t fit because they describe outcomes not driving the removal: improved shelf life is the result of removing the fats, not the issue itself; sweetness and fat content changes aren’t the direct problems posed by germ lipids.
