Most regulatory bodies have regulations for the moisture content of the individual foods and products to guarantee a consistent product with an acceptable shelf life for consumers. The moisture content of a product affects its taste, texture, and overall shelf life. Overly dry products can have a poor taste, while excessively moist products can lead to microbial growth and spoilage.
Products that have excessive moisture can form mold over time, so, measuring moisture content can help detect if products have proper moisture content throughout, even if the product may appear adequately dried on the surface.
