Post-mix syrup formulation

With certain exceptions the same formulation can be used for a dispensed drink as is used when it is bottled or canned. The key differences are  

Formulate a post-mix syrup with a ratio of 1 to 5.4 for a product containing the maximum amount of saccharin to meet a legal limit of 80 mg/1. 

Nominal syrup ratio is 1 volume syrup plus 5.4 volumes water (15.625% syrup). Maximum concentration occurs when syrup quantity is +5% of target and water quantity is —5% of target, i.e. maximum drink composition is 1.05 volumes syrup plus 5.13 volumes water (16.99% syrup). Thus to ensure a maximum saccharin content of 80 mg/1 in the drink, the syrup must contain a maximum of (80 X 100)/16.99 mg/1 of saccharin, i.e. = 470.9 mg/1. 

Assuming the syrup is also manufactured to an accuracy of 5%, then the target saccharin concentration must be (470.9 X 100)/105 mg/1 of saccharin, i.e. 448.4 mg/1. 

At a target ratio of 1 to 5.4, 448 mg saccharin per litre in the syrup would give 70 mg/1 in the drink.
