 Foreword  
Development of the East African Standa rds has been necessitated by the need for harmonizing requirements 
governing quality of products and services in the East African Community. It is envisaged that through 
harmonized standardization, trade barriers that are encountered when goods and service s are exchanged 
within the Community will be removed.  
In order to achieve this objective, the Community established an East African Standards Committee mandated 
to develop and issue East African Standards.  
The Committee is composed of representatives of the National Standards Bodies in Partner States, together 
with the representatives from the private sectors and consumer organizations. Draft East African Standards 
are circulated to stakeholders through the National Standards Bodies in the Partner States.  The comments 
received are discussed and incorporated before finalization of standards, in accordance with the procedures 
of the Community.  
East African Standards are subject to review, to keep pace with technological advances. Users of the East 
African St andards are therefore expected to ensure that they always have the latest versions of the standards 
they are implementing.  
EAS 801 was prepared by Technical Committee EAS/TC 014, Cereal, pulses and derived products  
In preparation of this standard assistan ce was d erived from: Codex Standard 175,  General Standard for Soy 
Protein Products . DEAS 801:2022

 Introduction  
Soya products are becoming a mainstream p art of regional dietary items. The benefit associated with the 
products includes among others the richness in protein  supply . This is of great benefit especially as an 
alternative protein source. However, it is important to note that soya has naturally high level of anti -nutritional 
properties related to trypsin inhibitor and tannins. The manufacturers are advised to app ly appropriate 
processing technologies to reduce these anti -nutrient properties to acceptable safe levels for human 
consumption.  
Soya Protein Products ( SPP) are foods produced by removing or decreasing certa in major non -protein 
constituents (water, oil, ca rbohydrates) from soya bean s or edible full fat soya flour  in a manner that achieves 
high protein comm ercial products with different protein content such as  Soya protein flour / Defatted Soya 
Protein flo ur (SPF or DS F), Soya Protein Concentrates (SPC) , and  Soya Protein  Isolates (SPI).  
This standard has been developed to ensure the safety and quality of edible full fat soya flour for human 
consumption.
