New Food Labelling Regulations (summary of R146 of 1 March 2010):

Reference: South African Government Gazette No. 9236, Vol 537, 1 March 2010, No. 32975

The minimum mandatory major Nutritional data to be printed on the product packaging is:

Energy Value in kiloJoules;
Protein in grams;
Glycaemic carbohydrates in grams: Of which Total Sugars: specify amount;
Total Fat in grams: Of which Saturated Fat: specify amount;
Dietary Fibre in grams;
Total Sodium (as Na) in milligrams.

The label must state the values per 100 gram (g), or per 100 milliliter (ml) and per serving size.

The number of samples required for submission to a testing laboratory must be as follows:

For products of relatively homogenous compositions, e.g. pasta, chips, cheese, etc., a minimum of 3 samples from different production batches.
For products of non-homogeneous compositions, e.g. mixed vegetables, ready to eat meals, cakes, etc., a minimum of 12 samples from different production batches.

The independent laboratory will test the composite sample of the 3 products/samples (or 12 products/samples) for the above nutritional information.
Please contact us, as below, should you require further information.

How to submit a sample:

If you are sending a sample to us for the first time or requesting any of our other services, then kindly complete and submit our Agreement of Service form, either on line or by fax.
If you are already a client of ours and have already submitted the Agreement of Service form, then you are only requested to submit your current requirements in writing, such as order number, what test to be done, etc., with the samples.
Perishable samples for bacteriological tests must be delivered to us at a temperature below 10°C, i.e. refrigerated or in a cooler box with ice blocks.
Products that are normally stored frozen should also be delivered to us in a frozen condition.
Upon delivery of the sample at our laboratories, kindly check and sign our Job Card after checking the details that our staff have filled in on the form, to avoid any misunderstanding about what you require.
