0 Foreword  
 
Fruit flavoured concentrates  are among beverages  sweetened with artificial  sweeteners which 
provi de 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  for people on diet  as a ready to drink beverage after reconstitution with potable 
water . 
 
The need to develop this Tanzania Standard was necessitated by the need to ensure the safety 
and quality of flavored fruit concentrates  being produced and marketed in Tanzania.  
 
In rep orting 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 re quirements, methods of  sampling and  test for fruit flavoured 
concentrates  intended for direct human consumption .
