Chemistry Testing

Overview

The opening of our new, accredited chemistry laboratory in 2013 in Midrand was in response to ongoing market demands for Mérieux NutriSciences to broaden our scope in South Africa and become a one-stop service provider to industry. Our service offering has been custom built with help from Mérieux NutriSciences Global and is aligned to the testing requirements of the South African Labelling Regulations. The turnaround time for results for the above analyses will be 10 – 15 business days. We will continue to ship samples to our laboratories in Europe where analyses, methods and product matrices are not included in the above offering.

Nutritional Labelling Tests

Nutritional labelling tests are necessary according to the regulations relating to the advertising and labelling of foodstuffs (R146 of 1 March 2010). This regulation stipulates that it is mandatory to add a table containing the typical nutritional information for the product, if one or more claims (e.g. “low fat”) are made.

According to R146 the mandatory nutritional information should be determined through chemical analysis in a reputable laboratory utilising SANAS or ILAC accredited methods.

As per R146, there are eight compulsory nutritional parameters:

  • Energy
  • Protein
  • Carbohydrates by difference/ Glycaemic carbohydrates
  • Total fat
  • Saturated fat (fatty acid profile)
  • Total sugar
  • Dietary fibre
  • Total sodium
