Avoiding the pitfalls of nutritional analysis

Pre analysis considerations

General considerations

Ensuring the correct method of analysis is chosen, to capture an accurate nutritional profile, relies on accounting for the variability of several factors. These can include:

For nutritional labelling, the Food Information for Consumers (FIC) Regulation states: The declared values shall, according to the individual case, be average values based on:

Despite the fact that nutritional analysis can be based on theoretical values, due to the nature of emerging ingredients, there may not be sufficient established data to calculate a profile; this may make it necessary to conduct nutritional analysis.

Understanding the limitations of a method can help when choosing the correct way to detect the desired nutrients. The limit of detection for a method is also an important factor, as it may affect whether you can detect the nutrient in the product. This is particularly important for micronutrients such as vitamins and minerals.

Health and nutrition claims

When making a claim on packaging, pre defined levels of the nutrient must be present in the final product. Whilst it is simple to test the product and establish these levels, it would also be prudent to factor in the level of error associated with the method used. This means that if the result is close to the border of whether a claim can be made or not, the developer can have confidence that it will be above the limit each time it is analysed. In order to make a claim the product has to fall above the threshold at all times, in contrast to the FIC nutritional labelling mentioned above.
