PRODUCT HIGHLIGHT PT-BV-517 - Dilutable/Ready to Drink
A real-world PT sample that focuses on undiluted and diluted non-alcoholic soft drinks. These samples aim to cover both sugar and non-sugar-based drinks and the analytes are again extensive. All routine areas from acidity (related to both taste and shelf life) to preservatives, sugars, sweeteners and other additives found in such products (e.g. caffeine) are included. Most of the analytes are covered by legal limits – hence the importance of the testing. 4 Rounds per Year
