Peanut Inspector Certification Practice Exam

For what purpose is a portion of the cleaned and shelled peanut sample used?

1. Flavor testing

2. Moisture content testing

3. Color grading

4. Texture analysis

The correct answer is: Moisture content testing

A portion of the cleaned and shelled peanut sample is used for moisture content testing to ensure the quality and shelf life of the peanuts. Moisture content is a critical factor in determining the safety and stability of peanuts during storage. High moisture levels can promote mold growth, leading to mycotoxin production, which can be harmful to health. Therefore, accurately measuring moisture content helps in assessing whether the peanuts meet safety standards and ensures they are suitable for consumption. While flavor testing, color grading, and texture analysis are also important factors in evaluating peanuts, moisture content testing is fundamental because it directly affects both the quality and preservation of the product. Without assessing moisture content, other evaluations may not accurately reflect the product's safety or quality.
