What visual characteristics are evaluated during the grading of peanuts?

The grading of peanuts involves an assessment of their visual characteristics to ensure they meet quality standards. The correct option highlights the importance of color, presence of defects, and overall appearance. Color plays a significant role because it can indicate ripeness and quality; for instance, certain peanut varieties have specific color expectations. The presence of defects, such as blemishes, discoloration, or any signs of disease or pest damage, is crucial as it directly affects the peanut's marketability and safety for consumption. Overall appearance encompasses the visual assessment of the peanuts as a whole, whereby inspectors consider factors that impact consumer appeal. This combination of visual characteristics ensures that only peanuts that meet the quality criteria are graded favorably, providing consumers with products that are both safe and desirable.
