Uganda National Bureau of Standards (UNBS) is a parastatal under the Ministry of Trade, Industry and 
Cooperatives established under Cap 327, of the Laws of Uganda, as amended.  UNBS is mandated to co-
ordinate the elaboration of standards and is  
(a) a member of International Organisation for Standardisation (ISO) and  
(b) a contact point for the WHO/FAO Codex Alimentarius Commission on Food Standards, and  
(c) the National Enquiry Point on TBT Agreement of the World Trade Organisation (WTO). 
The work of preparing Uganda Standards is carried out through Technical Committees. A Technical 
Committee is established to deliberate on standards in a given field or area and consists of representatives of 
consumers, traders, academicians, manufacturers, government and other stakeholders. 
Draft Uganda Standards adopted by the Technical Committee are widely circulated to stakeholders and the 
general public for comments. The committee reviews the comments before recommending the draft standards 
for approval and declaration as Uganda Standards by the National Standards Council.  
This Draft Uganda Standard, DUS DEAS 768:2017 , Fortified milled maize (corn) products  — Specification , is 
identical with and has been reproduced from an International Standard, ISO 768:2017, Fortified milled maize 
(corn) products  — Specification , and is being proposed for adoption as a Uganda Standard. 
This standard cancels and replaces the first edition US EAS 768: 2012, which has been technically revised. 
This standard was developed by Food and agriculture Standards Technical Committee (UNBS/TC 2).  
Wherever the words, “ East African Standard " appear, they should be replaced by "Uganda Standard." DRAFT FOR PUBLIC REVIEW

 Foreword 
Development of the East African Standards 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 services are exchanged 
within the Community will be removed.  
The Community has established an East African Standards Committee (EASC) mandated to develop and 
issue East African Standards (EAS).  The Committee is composed of representatives of the National 
Standards Bodies in Partner States, together with the representatives from the public and private sector 
organizations in the community .  
East African Standards are developed through Technical Committees that are representative of key 
stakeholders including government, academia, consumer groups, private sector and other interested parties. 
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 Principles and procedures for development of East African Standards. 
East African Standards are subject to review, to keep pace with technological advances. Users of the East 
African Standards are therefore expected to ensure that they always have the latest versions of the standards 
they are implementing .  
The committee responsible  for this document is Technical Committee EASC/TC 018, Nutrition and Foods for 
Special Dietary Uses . 
This second edition cancels and replaces the first 2012 edition (EAS 768: 2012), which has been technically 
revised. DRAFT FOR PUBLIC REVIEWEAS 768: 2017

 Introduction 
The Health Ministers of the East, Central and Southern Africa Health Community (ECSA-HC) passed a 
resolution in 2002 directing the Secretariat to work with the countries to fortify commonly consumed foods in 
the region after recognizing the high levels of malnutrition in the region. ECSA-HC is an intergovernmental 
organization that fosters cooperation in health among countries in the East, Central and Southern African 
Region. It has 10 active member states namely Kenya, Uganda, Tanzania, Malawi, Zambia, Zimbabwe, 
Lesotho, Swaziland, Mauritius and Seychelles. The mandate of the organization is to promote relevance and 
efficiency in health in the region. 
Following initial promotion efforts, the countries identified staple foods suitable for fortification as oil, sugar, 
maize meal/ flour and wheat flour. These foods can be used as vehicles to deliver essential micronutrients to 
the populations. Based on scientific evidence and working with countries using country data, the Secretariat 
developed implementation focused guidelines on fortification of these foods to help countries start up 
programs and scale up the existing programs. These guidelines included fortification levels for addition of 
micronutrients at the factory, and levels for monitoring at commercial level. 
Based on the guidelines and other available information, most of the countries in the East African Region and 
in the larger Africa have initiated national programs on oil fortification with vitamin A; and wheat and maize 
meal/ flour fortification with iron, zinc, folic acid, niacin, vitamin B-1, B-2, B6 and B-12 and vitamin A. Sugar 
fortification with vitamin A has also been considered as a way of supplementing other sources of the vitamin in 
order to prevent and reduce problems associated with the deficiency of this vitamin. Salt fortification with 
iodine continues to be implemented in all the countries. 
With the increased trade of food commodities including these fortified foods within the region, it has become 
imperative to develop regional standards that over and above the other standards, stipulate minimum and maximum 
levels of the added nutrients, provide clauses on how to pack the fortified product and the use of health and nutrition 
claims. The guidelines developed through ECSA have now been incorporated into food standards to provide for 
specific fortified products. 
It is envisaged that, the adoption of these standards and their utilization within the region will help countries adopt 
food fortification as a strategy to prevent, alleviate or eliminate micronutrient deficiency in the region. Standards will 
not only promote the health of the population but will also ensure safety of food products and enhance fair trade. 
This standard was developed with support from the East, Central and Southern Africa Health Community (ECSA-
HC) Secretariat. This was possible through a grant by the A2Z Project of the United States Agency for International 
Development (USAID). The financial and technical support was used in the process of formulation of fortification 
levels, development of the draft standards and mobilization of stakeholders to review the standard in national and 
regional fora. This support is hereby acknowledged.
