NATIONAL FOREWORD  
 
 
This Kenya Standard has been prepared by the Water Based flavoured Drinks Technical Committee under 
the guidance of the Standards Projects Committee and it is in accordance with the procedures of the Kenya 
Bureau of Standards.  
 
Water Based Flavoured  drink  in Solid Form is consumed as a drink after dissolving with potable water.  
 
Quality of the product is paramount if the consumer’s interests are to be protected.  
 
Being a solid product, Water Based flavoured  drink in Solid Form has a reasonable shelf -life if stored 
appropriately.  However, the quality of the product is monitored through incorporation of limits of parameters 
such as moisture content, microbiological status and heavy metal contaminants. This st andard also covers 
aspects related to packaging and labelling of the product.  
 
These products are being marketed as flavoured powders with nature identical, or artificial/synthetic flavors.   
 
During the preparation of this standard wide consultation and laboratory analysis was done.  
 
Acknowledgement is hereby made for the assistance obtained from various sources.
