Nutritional Data on Food Labels


As a minimum to fit the new guidelines, companies must supply sufficient nutritional information. The nutritional information needed is the levels of energy, fat, saturates, carbohydrate, sugars, protein and salt. 

Food scientists analyse and calculate the information for each food by doing different tests. They use expensive and precise machinery and technology to calculate the fat content, salt levels etc. There are two types of nutritional testing available.

Group 1 is the minimum nutritional declaration that is currently allowed. Group 1 testing will be ineffective after the 13th December 2014 as more information needs to be supplied on the labelling. Group 1 testing only finds the energy, protein, carbohydrates and fat. Therefore, Group 2 testing is more beneficial as it finds a lot more data which needs to be presented on the labelling. Group 2 nutritional testing finds energy, protein, carbohydrates, sugars, fats, saturates, fibre and sodium. The only other data needed is salt. This can be calculated using this formula:

Na = Amount of Sodium


(Na/22.99) * 58.443


The amount of sodium needs to be divided by 22.99 which is the atomic mass for sodium. The atomic mass for Chlorine is 35.453. Table salt is Sodium Chloride (NaCl). Therefore, the atomic mass for salt (NaCl) is approximately 58.443.Therefore, the formula is generated.


Here at Positive ID, we will supply a nutrition database to customers to ensure they are aware of the specific information.
