What is it? ​

Invertase (sucrase) is an enzyme that hydrolyses sucrose into glucose and fructose (invert sugar), mostly produced by yeast fermentation. In foods it is used to make soft-centred confectionery and prevent sugar crystallisation.

Source ​

Natural：酵母菌（如 Saccharomyces cerevisiae）等微生物发酵

Why is it used? ​

  • Converts sucrose to invert sugar for soft-centred chocolates
  • Prevents crystallisation in candies and syrups
  • Improves texture and moisture of pastry fillings
  • Lowers sweetness and enhances flavour
  • Processing aid improving stability

Common Foods ​

  • Soft-centred chocolates
  • Confectionery and frostings
  • Jams and syrups
  • Bakery fillings
  • Honey products
  • Artificial honey

Safety ​

ADI (Acceptable Daily Intake)：Not applicable (evaluated, no limit set)

Concerns：

  • 须源自安全菌株并声明转因状态
  • 极少数人对酶蛋白过敏
  • 需控制终产品中残留

Usage Standard ​

China：GB 2760《食品安全国家标准 食品添加剂使用标准》（酶制剂）；GB 1886.174 食品安全国家标准 食品添加剂 食品工业用酶制剂

International：

  • EU Regulation 1333/2008 Annex II (E 1103)
  • FDA Enzymes - GRAS (from GRAS organisms)
  • Codex GSFA (INS 1103)
  • FSANZ Food Standards Code (1103)
  • JECFA Monograph (Invertase)

In a nutshell ​

Invertase is an enzyme hydrolysing sucrose to invert sugar for soft-centred candies and anti-crystallisation, typically with no ADI.

Consumer Advice ​

Invertase is an enzyme that splits sucrose into glucose and fructose. It is commonly produced from yeast and is used to make invert sugar syrup, soft candies, cream-filled chocolates, and honey substitutes, preventing crystallization and improving texture. It is safe within approved limits, and being yeast-derived, it is suitable for vegetarian, halal, and kosher diets.
