What is modified corn starch?
Modified corn starch is native corn starch made resistant to process conditions by physical, enzymatic or chemical treatment. Native starch loses viscosity under long cooking, acidic conditions, intensive mixing and freeze-thaw cycles; modification removes these weaknesses. The term "modified" has nothing to do with genetic modification; it refers to physical and chemical rearrangement of the starch molecule.
Types of modification and what they do
Cross-linking (E1412 diphosphate, E1414 acetylated diphosphate) bonds granules together and confers resistance to high temperature, acid and shear. Stabilisation (E1420 acetylated, E1442 hydroxypropyl diphosphate) prevents molecular rearrangement (retrogradation) and stops water release in cold storage and freeze-thaw. Pre-gelatinisation (some grades including E1450) gives cold-water thickening for products with no cooking step. Most commercial products combine cross-linking and stabilisation.
Grade selection by application
Cross-linked grades for ketchup, fruit sauces and acidic products; stabilised grades for frozen ready meals, fruit fillings and chilled products; pre-gelatinised grades for powdered soups, pudding powders and no-cook mixes. Tell the supplier your product pH, maximum process temperature, shear level and storage condition (chilled/frozen); grade selection follows from these four facts.
Labelling and regulation
Modified starches are covered by food additive regulations and declared on the label as "modified starch" or by E number. Many modified starches may be used quantum satis under EU and Turkish regulations, though categories such as infant formula have restrictions. Check target market regulations for your product category.
Technical properties and quality criteria
Check the E number and modification type, moisture (≤ 13%), ash, pH, viscosity profile (RVA curve: peak viscosity, breakdown, setback), gelatinisation temperature, clarity, microbiological values, heavy metals, non-GMO and allergen statements. The viscosity curve is the most important indicator of process stability.
Wholesale sourcing: price and minimum order
The wholesale price of modified corn starch is set by the corn market, modification type, viscosity grade, origin (Türkiye, the EU and Thailand are common) and order quantity. The typical minimum order is one pallet (1000 kg). PERDIST identifies the right grade once your process is defined, compares sources and provides a written quotation with documents.

Specification summary
The values below come from the Modified Corn Starch page of the PERDIST catalogue and are confirmed per batch with the specification and certificate of analysis on every shipment.
| Field | Value |
|---|---|
| Typical properties | Moisture ≤ 13%, ash ≤ 0.5%, pH 5–7, white-cream colour; viscosity and gelatinisation temperature depend on grade. Values are set by the supplier specification. |
| Applications | Ketchup, mayonnaise and ready sauces, frozen ready meals, dairy desserts and yoghurt, instant soups, meat products, bakery creams and fruit fillings, dry mixes. |
| Formulation note | Choose the grade by process: cross-linked for acidic and high-temperature conditions; stabilised for freeze-thaw and cold storage; pre-gelatinised where no cooking step exists. Typical usage 2–6%. |
| Shelf life and storage | Typically 24 months in unopened packaging; store dry, cool and odour-free. |
| Packaging | Typically 25 kg kraft bags with PE inner liner; pallets of 1000 kg. Big bags (500–1000 kg) considered on request. |
| Minimum order | Usually one pallet (1000 kg). Smaller quantities for trial production are stated in the quotation depending on product and supplier. |
| Origin | Common origins: Türkiye, European Union, Thailand. Documented per lot in the quotation. |

Sample and approval steps
The steps from requesting a sample to the application trial and keeping a reference sample are set out in the ingredient sample evaluation and approval guide.
Regulatory and documentation context
Native starches count as a food ingredient while modified starches are additives and are declared on the label with their E numbers (E1412, E1414, E1422, E1442 and so on). For shipments to the EU, additives follow Regulation 1333/2008 and labelling Regulation 1169/2011.
