What characterizes sound mature kernels during inspection?

Sound mature kernels are characterized by being whole and free from visible damage, which is crucial for assessing their quality during inspection. Mature kernels that meet this standard are more likely to have a good flavor, texture, and storage capability, making them desirable for consumption and processing.

The integrity of the kernel plays a significant role in determining its suitability for sale and consumption; any visible damage could indicate contamination or a compromised structure, which can affect the quality of the peanuts. Therefore, the inspection process focuses on identifying those that are intact and show no signs of spoilage, insect damage, or disease.

While other choices mention issues like weight consistency, dryness, or screening processes, they do not directly relate to the primary characteristic of sound mature kernels, which is the absence of visible damage and maintaining whole structure. Thus, a focus on kernels that are undamaged is essential for ensuring high-quality peanuts.
