How Moisture Content is Determined?


Dear Reader, There is a very important test in the Feed Mill Quality Control Laboratory – Moisture Test or Moisture Content Analysis. So let’s first know what is Moisture Content?

Moisture is the water part (water) present in a sample. When a hot air oven is heated to a certain temperature and at a certain time, the water part evaporates and the percentage of moisture is extracted using the following formula. Moisture or moisture is an important parameter for feed raw materials and ready feed. This is because if the raw material or the feed has more moisture than the standard, the fungus grows in the feed and there is toxicity.

Lab Test – Moisture Content Detection

Necessary equipment and chemicals

  • Samples
  • Blender machine
  • Petridis
  • Analytical balance
  • Hot air oven
  • Desiccator

How to determine moisture percentage in feed?

  1. First a Petridis must be weighed by analytical balance.
  2. Then measure 05 or 10 grams of the sample in the Petridis and keep it in the hot air oven at a temperature of 135 degrees Celsius for 3-4 hours.
  3. Then cool for 30 to 35 minutes in the desiccator.
  4. Then again the weight of the sample including Petridis has to be taken.
  5. Humidity is the difference between the initial Petridis and the sum of the weight of the sample, including the Petridis after the hit. The percentage is then determined from the amount of sample.
  6. Calculation:
 Moisture % = [(Petridish wt. + Sample wt.) – (Dry wt. With petridish)] / Sample weight X 100%
