 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  Techn ical 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 t he 
Partner States. The comments received are discussed and incorporated before finalization of standards, in 
accordance with the Principles and procedures for develop ment 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 005 Food additives . 
Attention is drawn to the possibility that some of the elements of this document may be subject of patent 
rights. EAC shall not be held responsible for identifying any or all such patent rights.  DEAS 994: 2019

 Introduction  
Sucralose, (1,6 -dichloro -1,6-dideoxy -β-D-fructofuranosyl -4-chloro -4-deoxy -alpha -D-galactopyranoside) is a 
non-caloric artificial sweetener, approximately 650 times sweeter than sucrose (table sugar), twice as sweet 
as saccharin, and four times as sweet as aspartame. It has an Acceptable Daily Intake (ADI) of 15 mg/kg body 
weight.  
Its consumption has increased as result of the growing trends to consume low calorie foods with less impact 
on blood glucose than sucrose. It also has no effect on tooth decay and is commonly found in oral healt h 
products. It possesses the following sweetener characteristics: non -caloric, insipid and stability at high 
temperatures and in acidic medium. Its characteristics are preserved, even during pasteurisation, sterilisation 
and cooking at high temperatures. I n addition, it cannot be hydrolysed during digestion or metabolism due to 
the high stability of its carbon -chlorine bonds and it does not interact chemically with other foods.  
Sucralose -based products are found in a broad range of lower -calorie foods, inc luding, fizzy drinks, chewing 
gum, baking mixes, breakfast cereals and salad dressings.  
This standard has therefore been developed to prescribe requirements for  food grade  sucralose for use in 
food industry.

 Annex  C  
(normative)  
 
Test for chlorinated monosaccharides  
C.1  Apparatus  
TLC p lates  coated with 0.25 mm thickness of silica gel 60 or equivalent.  
C.2  Reagents  
C.2.1  Spray reagent . Dissolve 1.23 g p -anisidine and 1.66 g phthalic acid in 100 ml methanol. Store the 
solution in darkness and refrigerate to prevent it from becoming decolourised. Discard if solution becomes 
discoloured.  
NOTE  p-anisidine is toxic by skin absorption  and inhalation and should be used with due caution.  
C.2.2  Standard s olution A . Dissolve 10.0 g ± 0.001 g of mannitol in 40 ml of distilled water in a 100 ml 
volumetric flask. Dilute to volume using the water.  
C.2.3  Standard s olution B . Dissolve 10 g of ma nnitol and 40 mg of fructose (Analytical grade) in 25 ml of 
water in a 100 ml volumetric flask and make up to volume  with the water.

 Annex  D 
(normative)  
 
Assay: Percentage purity  
D.1  Apparatus  
D.1.1  Chromatographic system  
Fit a high -pressure liquid chromatograph, operated at room temperature, with a radial compression m odule 
containing a 10 cm 5 μm C 18 reverse phase column. The mobile phase is maintained at a pressure and flow 
rate (typically 1.5 ml/min) capable of giving the required elution time (see D.5). An ultraviolet detector that 
monitors absorption at 190 nm, or a refractive index detector is used.  
D.1.2  Mobile phase  
Add 150 ml of acetonitrile (HPLC grade, far UV, filtered through a 0.45 μm millipore filter or equivalent) to 850 
ml of water (glass distilled, filtered through a 0.45 μm millipore filter or equivalen t). Mix and degas thoroughly.  
D.2  Standard solution  
Weigh accurately about 250 mg of sucralose reference standard into a 25 ml volumetric flask. Dissolve and 
make up to volume using the mobile phase. Filter the solution through a 0.45 μm millipore filter or equivalent. 
Record the mass of reference standard as Ws. 
D.3  Test solution  
Weigh accurately about 250 mg of sample into a 25 ml volumetric flask. Dissolve and make up to volume 
using the mobile phase. Filter the solution through a 0.45 μm millipore fil ter or equivalent. Record the mass of 
sample as Wt. 
D.4  System suitability test  
Inject duplicate 20 μl portions of standard solution into the chromatograph. The retention time of the sucralose 
should be approximately 9 min. The co -efficient of variation ( 100 x standard deviation divided by mean peak 
area) for the peak areas should not exceed 2 %.  
NOTE  The retention time quoted is appropriate for a 10 cm 5 μm Rad -Pak C 18 column. If a column of a different 
make or length is used it may be necessary to adjust  the proportion of acetonitrile in the eluent to obtain the required 
retention time.  
D.5  Procedure  
Analyse the test solution under the conditions described above, making duplicate 20 μl injections, and 
calculate the mean peak area.  
The percentage purity from the relative peak areas of the test ( At) and standard solutions ( As), expressed as 
percent, shall be calculated as follows:  
Purity =
100 x  x  x 
t ss t
W AWA

E.1.2 Air oven  
E.1.3 Desiccator  
E.1.4 Weighing scale  
E.2  Sample preparation  
Weigh  1 to 2 g of sample (M 1). Tare a glass -stoppered, shallow weighing bottle that has been dried for 30 
minutes at 105 ºC. Transfer the sample into the bottle, replace the cover, and weigh the bottle and the sample 
(M2). Distribute the sample as evenly as pra cticable to a depth of about 5 mm, and not over 10 mm.  
E.3  Procedure  
Place the bottle with its contents in the drying chamber, removing the stopper and leaving it also in the 
chamber, and dry the sample at the 105 ºC for 2 hours. Upon opening the chambe r, close the bottle promptly 
and allow it to come to room temperature in a desiccator. Weigh the cool bottle and its contents (M 3).  
Calculate the loss on drying from the following equation:  
Loss on drying (%w/w) = 
  
where  
 M1 is the mass of s ample in grams;  
 M2 is the mass of sample and weighing bottle in grams before drying; and  
 M3 is the mass of sample and weighing bottle in grams after drying and cooling in a desiccator.  
If the sample melts at a temperature lower than 105 ºC, prepare the  sample as described above, then place it 
in a vacuum desiccator containing sulfuric acid. Evacuate the desiccator to 130 Pa (1 mm of mercury), 
maintain this vacuum for 24h, and then weigh the dried sample. Calculate the loss on drying using the same 
equat ion above.
