R1O-(CH2CH-CH2O)3-R3 (R1, R2, R3 is hydrogen or ricinoleic acid)


PGPR in Chocolates

No bad odor, has good thermal stability. 

1. Used in chocolate, add a small amount, can significantly improve the mobility of chocolate products, and save the amount of cocoa butter.
2. Expedit the process of filling and mold forming for chocolate products, optimize the process and make the small bubbles to discharge easily, and then avoid occurring empty holes and pore in the chocolate products.
3. Used with lecithin , has a good synergistic effect, thinning the thickness of & chocolate coating to make it easy to process.
4. In humid conditions, can reduce the viscosity. And form chocolate sugar coat quickly. And accelerate its conglutination . And increase adhesion, reducing the small pores.
Opeartion method and dosage

The suggestion of maximum in cocoa products, chocolate and its products, candy, chocolate coated products, ice cream coating: 5.0g/kg, oily-water fat emulsified products: 10g/Kg.
