Summary: China released new national food safety standards, including standards for some sweeteners.

National Food Safety Standard–Food Nutritional Fortifier: Polyfructose

  • Scope: This standard is applicable to polyfructose, a food nutritional fortifier extracted from chicory or Jerusalem artichoke tuber. The production processes include removing impurities by acid and alkali treatment or other methods, and drying.
  • Molecular formula: (C5-H12-O6)-(C6-H10-O5)n-2–(C6-H10-O5)(n=5~60)

National Food Safety Standard–Food Nutritional Fortifier: Fructo-oligosaccharides

  • Scope: This standard is applicable to the food nutritional fortifier FOS. There are two different classes of FOS mixtures. The first class of FOS is produced from chicory or Jerusalem artichoke. The components of this FOS are GF2 (kestose), GF3 (nystose), GF4 (FOS DP5/GF4), GF5 (FOS DP6/GF5), GF6 (FOS DP7/GF6), GF7 (FOS DP8/GF7), F2 (inulo-biose), F3 (inulo-triose), F4 (inulo-tetraose), F5 (inulo-pentaose), F6 (inulo-hexaose), F7 (inulo-heptaose), F8 (inulo-octaose). The production processes include the enzymatic hydrolysis of the raw material, membrane separation, purification and drying. The second class of FOS is obtained by the transfructosylation action of a β-fructosidase of Aspergillus oryzae or Aspergillus on sucrose. The production processes include purification and drying. This FOS mixture is composed of GF2, GF3, GF4 and GF5.

National Food Safety Standard–Food Nutritional Fortifier: Galacto-oligosaccharides

  • Scope: This standard is applicable to GOS, a food nutritional fortifier produced by β-galactosidase from TCC 31382 (Bacillus sp.) or Aspergillus oryzae using lactose as the raw material. The β-galactosidase catalyses the hydrolysis of lactose into galactose and glucose, and at the same time, the hydrolysed galactosides are transferred to the lactose molecule through the transfer of galactosides.
