Peanut Inspector Certification Practice Exam

What type of damage is not detected until the peanut kernel is split open?

1. Exterior blemishes

2. Rancidity, mold, or decay

3. Freeze damage

4. Physical crushing

The correct answer is: Rancidity, mold, or decay

Rancidity, mold, or decay refers to internal issues that often go unnoticed until the peanut kernel is split open. Unlike exterior blemishes or physical damage, which can be assessed visually from the outside, rancidity arises from chemical changes within the peanut due to oxidation, while mold or decay may develop internally. These conditions can compromise the quality and safety of the peanuts, making it imperative for inspectors to examine the kernels after splitting to verify their internal health. Thus, this type of damage requires a more invasive evaluation to be accurately detected.
