AOAC 2020.03 Energy Value Calculation in Processed Food

The AOAC International method 2020.03, titled “Energy Value of Foods,” is a critical tool for the accurate determination of energy content in processed foods. This service provides precise calculation and certification of the total digestible energy (TDE) in food products using this internationally recognized procedure.

Processed foods often undergo complex chemical transformations that can affect their nutritional composition, especially with respect to energy values. Traditional methods may not account for these changes accurately, leading to discrepancies in energy content reporting. The AOAC 2020.03 method addresses these challenges by providing a standardized approach.

The method involves the following steps:

Sample preparation: Properly preparing samples is crucial to ensure accurate results. This may include homogenization, drying, and grinding of the processed food sample.

Energy determination: The prepared sample undergoes combustion in an oxygen bomb calorimeter. This process releases the energy stored within the food matrix.
Correction factors: Various correction factors are applied to account for moisture, ash, and other components that do not contribute directly to the energy content.

The accuracy of the AOAC 2020.03 method is ensured by adherence to strict procedural guidelines outlined in the standard. This includes precise temperature control during combustion and consistent calibration of instruments used for moisture, ash, and mineral determination.

By using this method, laboratories can provide accurate, reliable, and standardized energy value data that are crucial for compliance with food labeling regulations across various regions. For instance, in the European Union (EU), the Regulation on Nutrition and Food Information requires manufacturers to declare the energy values of their products accurately.
