New UKAS accredited method: analysis of mixed additives for soft drinks and much more

Tuesday 31st October 2023

ALS in the UK announced that its mixed additives testing method AM/V/1003 has received accreditation from the United Kingdom Accreditation Service (UKAS). The method was developed in house based on Phenomenex Application ID No. 13010 − Soft Drink Additives. It includes 8 different analytes: acesulfame potassium, saccharin, theobromine, aspartame, quinine, potassium sorbate (sorbic acid), benzoic acid and caffeine.

The method has been accredited for analysing the products in the table at the bottom of this article, including soft drinks and other beverages, baked goods, and many other products. It is also suitable, though not accredited, for a variety of human foodstuff as well as animal feeds and for canine and equine health products.

The lowest reporting limit is 10 mg/kg. However due to the range of different matrices this may be elevated based on weights and dilution and interferences that are present. In such cases the LOQ maybe adjusted.

Potassium sorbate (sorbic acid) and benzoic previously analysed by AM/V/757, which also holds UKAS accreditation, will be withdrawn and the testing moved to AM/V/1003.

‘Achieving UKAS accreditation on our key methods is an involved process,’ says Gemma Parr, Vitamins and Additives Section Head at ALS in Chatteris, UK. ‘But going that extra mile gives our clients added confidence in their results.’
