As most vegetable drugs contain all the essential food requirements for mould, insects and mites, deterioration can be very rapid, once infestation has taken place. Various methods for moisture determination are loss on drying, separation and measurement of moisture, chemical methods, electrometric methods, and spectroscopic methods as per IP.1
REQUIREMENTS
Moisture content apparatus
Desiccators
Weighing Machine
PROCEDURE
10 gm of powder was weighed and placed it in a moisture content apparatus. Temperature was adjusted to 100-1100C till weight get constant and collected in desiccator and weighed. The loss of weight was regarded as a measure of moisture content as per IP.
CONCLUSION
Moisture content of the given sample is ______
