Typical moisture content range for artificial dehydration is which of the following?

• A. 20 to 30 percent
• B. 0 to 1 percent
• C. 1 to 5 percent
• D. 10 to 15 percent

Answer: (C)

Dehydration aims to remove enough water so the product is shelf-stable and resistant to microbial growth. Reaching a very low moisture content reduces the water activity available to microbes, slowing or stopping spoilage and enzymatic reactions during storage. For many artificially dehydrated products, about 1 to 5 percent moisture is the common target because it provides a safe balance between preserving quality and ensuring long shelf life. Higher moisture levels, like 20–30 percent, leave too much free water for microbes, while extremely low levels (near 0–1 percent) can be impractical to achieve without damaging texture, so 1–5 percent is the typical, effective range.
