The procedure involves these steps:
- Sample Preparation: A representative sample of meat is taken and homogenized to ensure uniform moisture distribution.
- Initial Weighing: The sample is weighed accurately using a calibrated balance. This initial weight is recorded.
- Drying: The sample is placed in a drying oven, typically set at a temperature of 105°C (221°F), for a specified period. The drying time varies depending on the type of meat and the size of the sample, but it is usually several hours.
- Cooling: After drying, the sample is removed from the oven and allowed to cool in a desiccator to prevent moisture reabsorption from the environment.
- Final Weighing: The cooled sample is weighed again using the same calibrated balance. This final weight is recorded.
- Calculation: The moisture content is calculated as the difference between the initial weight and the final weight, expressed as a percentage of the initial weight.
Several factors can affect the accuracy of the drying oven method. These include:
- Temperature Control: Maintaining a stable and accurate oven temperature is for consistent results.
- Drying Time: Insufficient drying can lead to underestimation of moisture content, while excessive drying can cause decomposition of the sample and inaccurate results.
