NATIONAL FOREWORD 
 
 
This Kenya Standard has been prepared by the Water Based flavou red Drinks Technical Committee under 
the guidance of the Standards Projects Committee and it is in a ccordance with the procedures of the Kenya 
Bureau of Standards.   
Water Based Flavoured drink in Solid Form is consumed as a drin k 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 For m has a reasonable shelf-life if stored 
appropriately.  However, the quality of the product is monitore d through incorporation of limits of parameters 
such as moisture content, microbiological status and heavy meta l contaminants. This standard also covers 
aspects related to packaging and labelling of the product.  
 These products are being marketed as flavoured powders with nat ure identical, or artificial/synthetic flavors.   
 
During the preparation of this standard wide consultation and l aboratory analysis was done.  
 
Acknowledgement is hereby made for the assistance obtained from  various sources.
