Article 1
The Standards are prescribed in accordance with the provisions of Article 17 of the Act Governing Food Safety and Sanitation.
Article 2
Gum Arabic (Gum arabic；Acacia gum) as food raw material shall comply with the following specifications:
1. Definition: Gum arabic is a dried exudate obtained from the stems and branches of strains of Acacia senegal (L.) Willdenow or closely related species of Acacia (family Leguminosae). It consists mainly of high-molecular weight polysaccharides and their calcium, magnesium and potassium salts, which on hydrolysis yield arabinose, galactose, rhamnose and glucuronic acid.
2. Description and Identification: The unground product occurs as white to orange-brown, spheroidal tears of varying size or in angular fragments. Gum arabic is also available commercially in the form of white to yellowish-white flakes, granules, powder, roller dried, or spray-dried material. One gram dissolves in 2 mL of water, forming a solution that flows readily and is acid to litmus, insoluble in ethanol.
3. Purity:
(1) Loss on drying: Not exceed 15% (105°, 5 h) for granular and exceed 10% (105°, 4 h) for spray dried material.
(2) Total ash: Not exceed 4%.
(3) Acid-insoluble ash: Not exceed 0.5%.
(4) Acid-insoluble matter: Not exceed 1%.
(5) Starch or dextrin: Boil a 1 in 50 solution of the sample, cool and add a few drops of Iodine T.S. No bluish or reddish colour should be produced.
(6) Tannin-bearing gums: To 10 mL of a 1 in 50 solution of the sample, add about 0.1 mL of ferric chloride TS. No blackish colouration or blackish precipitate should be formed.
(7) Microbiological criteria:
Salmonella spp.: Negative.
E. coli: Negative.
(8) Arsenic: Not exceed 3 mg/kg.
(9) Lead: Not exceed 2 mg/kg.
(10) Mercury: Not exceed 1 mg/kg.
(11) Cadmium: Not exceed 1 mg/kg.
