Starch Sodium Octenyl Succinate
Also known as: E1450
Starch sodium octenyl succinate is permitted under 21 CFR 172.892 (food starch-modified) with the OSA treatment limited to 3% of starch weight. EFSA (2017) re-evaluated all modified starches, including E1450, and concluded an ADI 'not specified' is appropriate, indicating no safety concerns at current uses.
What it is
Starch sodium octenyl succinate (E1450 / SSOS) — a chemically modified starch produced by treating starch with octenyl succinic anhydride (OSA).
Emulsifier, thickener, stabilizer, encapsulating agent (especially for flavor oils and beverage clouds).
What regulators actually say
"Food starch may be modified by treatment with 1-octenyl succinic anhydride, not to exceed 3 percent."
"EFSA Panel re-evaluation of modified starches as food additives concluded an ADI 'not specified' is appropriate."
