0 Foreword  
 
Artificially sweetened flavoured drinks in solid form are among beverages    sweeten ed 
with "non -nutritive” artificial sweeteners which provide a sweet sensation to the taste 
buds, without raising blood sugar levels, they are calorie free products consumed for diet 
purposes.  
These products are currently produced in Tanzania and some are imported for direct 
human consumption.  
 
The need to develop this Tanzania Standard was necessitated by the need to ensure the 
safety and quality of artificially sweetened flavoured drinks in solid form being produced 
and marketed in Tanzania.  
 
In reporting  the result of a test or analysis made in accordance with the Tanzania 
Standard, if the final value observed or calculated is to be rounded off, it shall be done in 
accordance with TZS 4 (see clause 2)  
 
 
  
 
1 Scope  
 
This Tanzania S tandard specifies require ments, methods of  sampling and  test for artificially 
sweetened flavored drinks in solid form intended for direct human consumption for people on diet  
as a ready to drink beverage after reconstitution with potable water.
