Why is humidity considered detrimental post-harvest?

Humidity is considered detrimental post-harvest primarily because it creates conditions that are conducive to faster spoilage and mold growth. When peanuts are harvested, they need to be stored in a controlled environment to prevent moisture from impacting their quality. High humidity levels can lead to the absorption of excess moisture by the peanuts, which fosters an environment ideal for mold and bacteria to thrive. This not only compromises the safety of the peanuts by making them potentially hazardous for consumption but also affects their shelf life significantly.

Spoilage can manifest as off-flavors, rancidity, and degradation of texture, making the peanuts unfit for processing or sale. Ensuring low humidity conditions post-harvest is therefore essential for maintaining the quality and safety of peanuts and preventing economic losses in the agricultural sector.
