What is chemically modified starch?+
Chemically modified starch is native starch that has been treated with chemicals to alter its molecular structure, improving properties such as heat stability, shear tolerance, freeze-thaw stability, acid resistance, or emulsification. Common modifications include cross-linking, substitution, oxidation, and acid-thinning.
Is modified food starch safe?+
Yes. All E-number modified starches (E1401–E1452) are approved food additives by the EU, FDA, and Codex Alimentarius. They are produced under strict food safety management systems including ISO 22000 and are safe for consumption at recommended usage levels.
What is modified food starch made from?+
Modified food starch is made from native starches derived from corn (maize), waxy corn, tapioca, potato, or wheat. The native starch undergoes chemical reactions such as cross-linking, esterification, etherification, or oxidation to produce the final modified starch.
Is modified starch gluten free?+
Most modified starches are naturally gluten-free, especially those derived from corn, tapioca, and potato. Wheat-based modified starch may contain trace gluten. Contact us for specific gluten-free certification requirements.
What are the E-numbers for modified starch?+
The main E-numbers for chemically modified starch are: E1401 (Acid Modified Starch), E1404 (Oxidized Starch), E1412 (Distarch Phosphate), E1413 (Phosphated Distarch Phosphate), E1414 (Acetylated Distarch Phosphate), E1420 (Acetylated Starch), E1422 (Acetylated Distarch Adipate), E1440 (Hydroxypropyl Starch), E1442 (Hydroxypropyl Distarch Phosphate), and E1450 (Starch Sodium Octenyl Succinate).
Modified corn starch vs cornstarch — what is the difference?+
Cornstarch is unmodified native starch from corn. Modified corn starch has been chemically treated to improve its functional properties such as heat stability, freeze-thaw resistance, or emulsification. Modified corn starch performs consistently under industrial processing conditions where native cornstarch would break down.
Is modified starch vegan?+
Yes. All chemically modified starches are derived from plant-based native starches (corn, tapioca, potato, wheat) and are suitable for vegan formulations.
How is modified starch made?+
Modified starch is produced by treating native starch with chemical reagents under controlled temperature, pH, and reaction time. Cross-linking uses agents like STMP or POCl₃; substitution uses acetic anhydride or propylene oxide; oxidation uses sodium hypochlorite. The reaction is then neutralized, and the starch is washed and dried.
What is the difference between E1442 and E1422?+
E1442 (Hydroxypropyl Distarch Phosphate) is cross-linked and etherified: it delivers strong freeze-thaw stability plus acid and shear resistance, making it the first choice for frozen foods, dressings and canned products that must survive repeated freeze-thaw cycles. E1422 (Acetylated Distarch Adipate) is cross-linked and esterified: it gives a short, clean, clear paste with a bland flavor, preferred for sauces, condiments and dairy desserts where clarity and taste neutrality matter. We produce both and can send side-by-side samples.
What is the minimum order quantity for chemically modified starch?+
There is no MOQ. We support small-batch customization starting from 25 kg trial batches for formulation validation, and can scale up to full 20 ft container loads once the formula is approved. Free lab samples ship within 48 hours.
Can I combine different E-codes in one order?+
Yes. Our 4 production lines and flexible scheduling allow multiple E-code variants to be produced and consolidated into a single mixed-container shipment, which saves freight costs and simplifies customs paperwork. Tell us the E-codes and ratios you need, and we will quote the combined container.
