What is it?
invertase (INS 1103) is a Enzyme preparation food additive. Catalyses specific biochemical reactions to improve processing or quality (e.g. hydrolysis, inversion, clarification).
Source
Natural：Produced by microbial fermentation or extraction/purification from plants/animals (e.g. invertase, glucose oxidase, lysozyme).
Industrial：Made by fermentation, extraction and purification.
Why is it used?
- Catalyse specific reactions
- Improve texture and flavour
- Enhance processing efficiency
Common Foods
- Bakery
- Dairy
- Brewing
- Fruit juice
- Starch sugar
Safety
Enzymes are mostly proteins inactivated or digested during processing; safe within permitted use; JECFA and authorities set source and purity requirements.
Metabolism：Metabolic pathways vary by substance; generally the material is metabolised or excreted normally.
Concerns：
- Use within permitted levels
- Sensitive individuals should check the ingredient list
Usage Standard
China：依据 GB 2760《食品安全国家标准 食品添加剂使用标准》确定使用范围与最大使用量；具体限值随食品类别而异。
