E1451Acetylated oxidised starch
E1451 is acetylated oxidised starch. In Appendix 1 of Circular 24/2019/TT-BYT it is listed with the functions: emulsifier, stabilizer, thickener.
Did you know? Acetylated oxidised starch is made by treating starch with sodium hypochlorite and then esterifying it with acetic anhydride.

Is acetylated oxidised starch harmful?
In 2017 EFSA re-evaluated 12 modified starches, including E1451. It concluded that there is no safety concern at the reported uses and use levels for the general population and no need for a numerical ADI. At the 95th percentile (brand-loyal scenario), combined intake of E1404–E1451 was up to 3,053 mg/kg body weight a day, in toddlers.
Is acetylated oxidised starch permitted in Vietnam?
Yes. Acetylated oxidised starch (INS 1451) is listed in Appendix 1 of Circular 24/2019/TT-BYT, the list of additives permitted in food.
Can children and pregnant women have E1451?
In 2017 EFSA concluded that the available data did not allow an adequate assessment of the safety of E1451 in dietary foods for babies and young children for special medical purposes (category 13.1.5.2) at the maximum level then authorised, 50,000 mg/kg. EFSA noted that children eating these foods may be more susceptible to gastrointestinal effects because of their underlying medical condition. The source says nothing specific about pregnant women. If you have a particular health condition, ask a doctor.
