 Foreword  
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 key stakeholders 
including government, academia , consumer groups, private sector and other interested parties.  
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.  
The committee responsible for this document is Technical Committee UNBS /TC 5, Chemicals and 
Environment products .

 Annex A 
(normative)  
 
Determination of peroxide value  
A.1 Principle  
The sample is treated in solution with a mixture of acetic acid and a suitable organic solvent and then with a 
solution of potassium i odide. The liberated iodine is titrated with a standard solution of sodium thiosulfate  
A.2 Reagents  
A.2.1  Glacial acetic acid  
A.2.2  Chloroform  
A.2.3  Potassium iodide solution  
Saturated, freshly prepared  
A.2.4  Standard sodium thiosulphate solution  
0.01 N fr eshly standardized   
A.2.5  Starch indicator solution  
Mix 5 g of starch and 0.01 g mercuric iodide with 30 ml of cold water and slowly pour it while stirring into one 
litre of boiling water. Boil for three minutes. Allow to cool and decant off the supernatan t clear liquid.  
A.3 Procedure  
A.3.1  Weigh accurately about 5 g of the sample in a 250 ml glass stoppered conical flask and dissolve by 
shaking in 30 ml of a mixed solvent containing 3 parts by volume of glacial acetic acid and 2 parts by volume 
of chlorofo rm. Add 0.5 ml of saturated potassium iodide solution, allow the solution to stand for exactly one 
minute with occasional shaking, then add 30 ml of water and titrate with standard sodium thiosulphate 
solution.  
A.3.2  Add the thiosulphate solution until the  colour of the titrated solution becomes light yellow. Then add 1 
ml of starch indicator and continue the titration until the disappearance of the blue colour.  
A.3.3  Carry out a blank determination without using the sample.

 Annex  B 
(normative)  
Determination of total viable count  
B.1 Outline of the method  
The test consists of plating a known dilution of the sample or any di gest agar medium (soya bean casein is 
recommended) suitable for the total count of bacteria and fungi after incubating them for a specified period to 
permit the development of visual colonies.  
IMPORTANT Take precaution in ascertaining that only fresh samp les, from carefully sealed containers that 
had not been opened before, are used for this test. This is very necessary for getting accurate results.  
B.2 Apparatus  
B.2.1 Tubes , of resistant glass, provided with closely fitting metal caps  
B.2.2 Autoclaves , of sufficient size. They shall keep uniform temperature within the chamber up to and 
including the sterilizing temperature of 122 °C. They shall be equipped with an accurate thermometer, located 
so as to register the minimum temperature within the sterili zing chamber, a pressure gauge and properly 
adjusted safety valves.  
B.2.3 Petri dishes , of 100 mm diameter and 15 mm depth. The bottom of the dishes shall be free from 
bubbles and scratches and shall be flat so that the medium is of uniform thickness thro ughout the plate.  
B.2.4 Colony counter , an approved counting aid, such as Quebec colony counter. If such a counter is 
not available, counting may be done with a lens giving a magnification of 1.5 diameter. In order to ensure 
uniformity of conditions durin g counting, illumination equivalent to that provided by Quebec colony counter 
shall be employed.  
B.2.5 Balance  
B.2.6 pH meter  
B.2.7 Water bath  
B.3 Medial buffer  
B.3.1 Soya bean casein digest agar medium  
Dissolve 15 g of pancreatic digest of casein 5 g of papaic digest of soya bean meal, and 5 g of sodium 
chloride in 100 m l of distilled water contained in a 2 -litre beaker by heating in a water bath. Add 15 g of 
powdered agar and continue boiling until the agar is completely digested. Adjust the pH to 7 .5 with sodium 
hydroxide solution. Distribute in 20 -ml quantities, close the tubes with metal caps and autoclave at 123 °C for 
20 min. After autoclaving, store the tubes in a cool place and use them within three weeks.  DUS 1833: 2017  
8 © UNBS 2017  – All rights reserved  
 B.3.2 Stock solution pH 7.2 phosphat e buffer  
Dissolve 34 g of monobasic potassium phosphate in about 100 mL of water contained in a 500 -ml volumetric 
flask. Adjust the pH 7.2 ± 0.1 by the addition of 4 % sodium hydroxide solution. Add water to volume and mix. 
Sterilize at 122 °C for 20 min.  Store under refrigeration.  
B.3.3 Dilute phosphate buffer solution pH 7.2  
Dilute 1 m l of stock solution with distilled water in the ratio of 1:800. Fill 50 m l in each of the conical flask of 
100 m l capacity. Plug the flasks with cotton and sterilize at 1 22 °C for 20 min.  
B.4 Sterilization of apparatus  
B.4.1 Tubes  
These shall be sterilized in the autoclave at 122 °C temperature and 1.05 kg/cm 2 pressure for 20 min or in a 
hot oven at 160 °C for one hour.  
B.4.2 Petri dishes  
These shall be packed in drum s and autoclaved at 122 °C temperature and 1.05 kg/cm 2 pressure for 20 min or 
individually wrapped in Kraft  paper and sterilized in a hot air oven at 160 °C for one hour.  
B.4.3 Pipettes  
These shall be placed in pipette cones (copper, stainless steel or a luminium) after plugging the breeder end 
with cotton and sterilized in the autoclave at 122 °C temperature and 1.05 kg/cm 2 pressure for 20 min, or at 
160 °C for one hour in the air oven.  
B.5 Procedure  
B.5.1 Melt a sufficient number of soya bean casein di gest agar medium tube in a hot water bath and 
transfer while hot in to a constant temperature water bath maintained at 48 °C ± 20 °C.  
B.5.2 Weigh and transfer aseptically 1 g of the sample to a conical flask containing sterile 50 m l or any 
suitable diluti on factors of dilute phosphate buffer at pH 7.2. Shake well. Pipette out in 1 m l portions into three 
sterile petri dishes. Pour melted and cooled (at 45 °C) soya bean casein digest agar medium over it, and 
rotate to mix thoroughly. Incubate the plate at 32  °C for 72 h in an inverted position.  
B.6 Expression of results  
Get the average number of colonies on soya bean casein digest agar medium plates and determine the 
number of micro -organisms per gram of the sample.  If no colony is recovered from any of the  plates it can be 
stated as less than 50 micro -organisms per gram  DUS 1833 : 2017
