<p>The present invention provides a method of measuring moisture content of an object for drying during drying in a drying chamber by, for example, freeze-drying, fluidized bed drying or shelf drying, in real-time and in a non-destructive manner. According to the present invention, when measuring moisture content of an object for drying, a near infrared absorption spectrum of moisture present around the object for drying is measured, and the moisture content of the object for drying is calculated from a predetermined relationship based on a measured amount obtained from the measured near infrared absorption spectrum.</p> |
