Peanut Inspector Certification Practice Exam

When is a peanut considered discolored in relation to its shell?

1. When it feels wet

2. When it smells stale

3. When it has a darker shade of brown

4. When it looks cracked

The correct answer is: When it has a darker shade of brown

A peanut is considered discolored in relation to its shell when it has a darker shade of brown. This discoloration can indicate a variety of issues, such as potential spoilage or damage, which may affect the peanut's quality and edibility. The color of the shell is an important visual cue in the grading process, as the expected color for a healthy, well-processed peanut is typically a light tan or yellow-brown. A shift to a darker hue suggests that the peanut may have been exposed to unfavorable conditions, such as excessive moisture or prolonged storage, which can lead to mold or other issues. In contrast, other options describe sensory attributes that do not specifically relate to discoloration. For instance, the feel of wetness, stale smell, or visible cracks can indicate other forms of deterioration or issues but do not directly relate to the color change of the peanut shell itself. Thus, focusing on the darker shade of brown is the most precise indicator of discoloration.
