Distarch phosphate

Distarch phosphate (CAS 55963-33-2), also identified by its E-number E1412, is a chemically modified starch produced by cross-linking native starch with phosphate groups.

Where is Distarch phosphate used?

• Food manufacturing: thickener and stabilizer in sauces, soups, gravies, and dressings where heat and acid processing would degrade unmodified starches
• Frozen and retort foods: maintains gel structure and prevents syneresis through repeated freeze-thaw cycles
• Bakery and dairy: improves mouthfeel and extends shelf life in yogurts, puddings, and cream fillings
• Pulp and paper: improves surface sizing and wet-end retention, contributing to sheet strength and formation consistency
• Classified as RS4 resistant starch, it delivers controlled texture, improved freeze-thaw stability, and enhanced viscosity retention in processed food systems.
• In low-pH foods, gives a smooth, short texture when hot and sets to a tender, soft gel on cooling.
• In processed meats and sausages, binds water and improves texture, reduces shrinkage during cooking and increases juiciness.

Formulation notes

• Properties are similar to those of hydroxypropyl starch (E 1440), but it can also form gels and withstand heavy loads.

Typical specification

• May contain 70-85% RS4 resistant starch, depending on the degree of modification, and can replace high-glycemic flour in functional bread and other baked goods.
• The amount of phosphate introduced is at most 0.04% P.
• Starches treated with STMP and STPP must not exceed 0.4 percent phosphorus as residual phosphate.
• pH value of 6-7.5.

Regulatory status

• Listed in the Codex GSFA online database of food additives with the INS number 1412.
• In 2011, the European Food Safety Authority approved a health claim that any type of resistant starch, including modified resistant starch, can reduce postprandial glycemic response in foods if high-carbohydrate baked goods contain at least 14% of total starch as resistant starch.

Frequently asked questions about Distarch phosphate

In which beverage applications is distarch phosphate used as a stabilizer?

In flavored milk, coffee creamers and other beverages, it acts as a stabilizer, keeping the beverage homogeneous and preventing sedimentation of solids.
