Questions about amylase
Is alpha-amylase harmful?
The JECFA database (the FAO/WHO expert committee) lists each alpha-amylase preparation (INS 1100) separately by its source organism. Alpha-amylase from Bacillus stearothermophilus (1990), Bacillus subtilis (1990), Bacillus licheniformis (1985) and Aspergillus oryzae (1987) all have an ADI of “not specified”, meaning no numerical ADI is needed. These are JECFA evaluations, not EFSA opinions or the current EU rule.
Is E1100 permitted in Vietnam?
Yes. Amylase (alpha-amylase) (INS 1100(i), 1100(ii), 1100(iii), 1100(iv), 1100(v), 1100(vi)) is listed in Appendix 1 of Circular 24/2019/TT-BYT, the list of additives permitted in food.
