Fundamentals of Moisture Sorption Isotherms

2019-1-12such as quality and safety To completely understand water relations in a product requires an understanding of the amount of water (moisture content) that can be held at a given energy state (water activity) Moisture sorption isotherms describe the relationship between water activity and moisture content at a constant temperature

III Seed Moisture Content

2018-3-28The moisture content of a seed will equilibrate with the relative humidity of the air surrounding it This moisture content is called the equilibrium moisture content and because it is constant for any species at known temperature and relative humidity it can be used as an approximation of the actual seed moisture content
