a) Karl Fischer method
b) Nuclear moisture meter method
c) Loss on drying moisture meter method
d) Near infrared moisture meter method
Answer: d
Explanation: Near infrared moisture meter method uses absorbance and reflectance principles for determining the moisture content. This meter focuses a beam of light on the product and then the light is filtered to a wavelength that excites the moisture molecules. The higher the amount of moisture content, higher is the amount of light absorbed.
