CD/K/4:2013 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. 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 Standards are therefore expected to ensure that they always have the latest versions of the standards they are implementing. CD/K/4 was prepared by Technical Committee EASC/ TC/019, Sugar and Sugar products. iv EAC 2013 All rights reserved

Annex A (normative) Determination of ph in dextrose monohydrate (glucose powder) Weigh 10 g of glucose powder and dissolve it in 100 ml of carbon dioxide-free water. Take the reading of the solution (ph) using a ph meter. 8 EAC 2013 All rights reserved

Annex B (normative) Determination of total acidity in dextrose monohydrate (glucose powder) Dissolve 5.0 g of glucose powder in 50 ml of carbon dioxide-free water. Add a few drops of phenolphthalein indicator and titrate with 0.020 N sodium hydroxide to a distinct pink colour. Not more than 0.30 ml is required for neutralization. Calculate the total acidity as HCl/g. Total acidity = Titre used x Normality Weight of the sample (g) EAC 2013 All rights reserved 9
