National Food Safety Standard -
Food additive - Arabic gum
1 Scope
This standard is applicable to food additive Arabic gum of which, prepared by
physical processing, the raw material is obtained from the gelatinous
secretions of stems of Arabic gum-tree [Acacia senegal (L.) Willdenow] or the
similar Acacia tree [Acacia seyal (Fam. Leguminosae)].
2 Technical requirements
2.1 Sensory requirements
Sensory requirements shall meet the requirements of Table 1.
Table 1 -- Sensory requirements
Item Requirement Inspection method
Color White to brown Take an appropriate amount of sample; place it in a white
porcelain dish; observe under natural light. State Granular or powder
2.2 Physical and chemical indicators
Physical and chemical indicators shall meet the requirements of Table 2.
Appendix A
Testing method
A.1 General provisions
Unless otherwise specified in this standard, the purity of the reagents used
shall be above analytical purity; the standard titration solution used, the
standard solution used for the determination of impurities, the preparations and
products shall all be prepared according to the provisions of GB/T 601, GB/T
602, and GB/T 603. The experimental water shall comply with Grade-3 water
in GB/T 6682-2008. When the solution used in the test does not indicate which
solvent is used for preparation, then it refers to the aqueous solution.
A.2 Identification test
A.2.1 Solubility
1g of sample is soluble in 2mL of water; it is not soluble in ethanol.
A.2.2 Optical rotation
Weigh 1g of sample (calculated on a dry basis); dissolve it in 100 mL of water;
let it stand for defoaming; that is the sample solution. Use a 200mm
optical-rotation tube; use the method in GB/T 613 to determine the specific
optical-rotation of the sample solution. For sample solution from the Arabic
gum-tree, it shall be left-rotated; For sample solution from Acacia tree, it shall
be right-rotated.
A.3 Determination of acid-insoluble ash
A.3.1 Reagents and materials
Hydrochloric acid solution: 10%.
A.3.2 Analysis steps
Measure 25mL of hydrochloric acid solution; add it to the ash that was
obtained during ash determination; boil for 5min. Use filter crucible or ashless
filter paper to filter; use hot water to wash the filter residue for several times;
burn to constant-weight at 800°C ± 25°C.
