National Food Safety Standard -- Food Additive -- Sodium
Starch Octenyl Succinate
1 Scope
This Standard applies to the food additive sodium starch octenyl succinate produced by
esterification of starch and octenyl succinic anhydride, as well as a combination of
enzyme treatment, dextrinization, acid treatment, bleaching treatment, and
pregelatinization.
2 Technical requirements
2.1 Sensory requirements
Sensory requirements should comply with Table 1.
2.2 Physical and chemical indicators
The physical and chemical indicators should comply with the provisions of Table 2.
Annex A
Inspection methods
A.1 General
Unless other requirements are specified, the reagents and water used in this Standard
refer to analytically pure reagents and grade three water specified in GB/T 6682. The
standard solutions, standard solutions for impurity determination, preparations and
products used in the test shall be prepared in accordance with the provisions of GB/T
601, GB/T 602 and GB/T 603, unless other requirements are specified. The solutions
used in the test refer to aqueous solutions unless the solvent used to prepare them is
specified.
A.2 Identification tests
A.2.1 Iodine staining test
Weigh 1 g of the specimen and add it to 20 mL of water to form a suspension. Add a
few drops of iodine solution. The color is dark blue to brownish red.
A.2.2 Copper reduction test
A.2.2.1 Reagents and materials
Hydrochloric acid solution: 7+93.
A.2.2.2 Analysis steps
Weigh 2.5 g of the specimen and place it in a long-neck flask. Add 10 mL of
hydrochloric acid solution and 70 mL of water. Well mix them. Reflux for 3 h. Cool
them down. Take 0.5 mL of cooled solution. Add 5 mL of hot alkaline copper tartrate
TS. A large amount of red precipitate is produced.
To prepare alkaline copper tartrate test solution, follow the steps below.
a) Solution A: Weigh 34.66 g of copper sulfate crystals (CuSO4 · 5H2O). The crystals
should show no signs of weathering or moisture absorption. Add water to dissolve
and adjust the volume to 500 mL. Keep this solution in a small airtight container.
b) Solution B: Weigh 173 g of potassium sodium tartrate crystals
(KNaC4H4O6 · 4H2O) and 50 g of sodium hydroxide (NaOH). Add water to
dissolve and adjust the volume to 500 mL. Store this solution in a small, alkali-
resistant container.
c) Mix solution A and solution B in equal volumes to obtain alkaline copper tartrate
