What humidity level is recommended for dry storage?

1. 30%

2. 40%

3. 50%

4. 60%

The correct answer is: 50%

The recommended humidity level for dry storage is around 50%. Maintaining this level is crucial because it helps prevent the growth of mold and bacteria, which can thrive in higher humidity levels. Additionally, low humidity levels, such as those below 30%, can lead to the degradation of food quality, causing items like grains and cereals to become too dry, resulting in spoilage or loss of flavor and nutritional value. The 50% humidity level strikes a balance, ensuring that food products remain stable and safe while also not promoting spoilage. This is essential in a food storage environment where proper preservation is key to maintaining food safety and quality.
