How are peanuts primarily graded?

Peanut grading primarily focuses on a variety of factors including size, shape, color, and defects. This comprehensive grading system allows inspectors to assess the overall quality and marketability of peanuts. Size and shape play a crucial role in determining uniformity and suitability for various uses, while color and the presence of defects can indicate the quality and freshness of the peanuts. These aspects are vital for consumers and manufacturers who need to ensure that the peanuts meet specific quality standards for both culinary and commercial purposes. Thus, the primary grading process is designed to evaluate these diverse criteria in order to classify peanuts effectively.
