A. Yes. To obtain certificates, please visit the certificates section of this website.

Q. What is maltodextrin?
A. The Food and Drug Administration (FDA) defines maltodextrins, (C6H10O5)n•H2O, CAS Reg. No. 9050-36-6, as non-sweet, nutritive saccharide polymers that consist of D-glucose units linked primarily by alpha-1-4 bonds, having a DE less than 20. They are prepared as a white powder or concentrated solution by partial hydrolysis of corn starch with safe and suitable acids and/or enzymes.

Q. What are Corn Syrup Solids?
A. MALTRIN® corn syrup solids are defined by the FDA as dried glucose syrup with a DE of 20 or higher.

Q. What is DE?
A. Dextrose Equivalence is a quantitative measure of the degree of starch polymer hydrolysis. It is a measure of reducing power compared to a dextrose standard of 100. The higher the DE, the greater the extent of starch hydrolysis. As the product is further hydrolyzed (higher DE), the average molecular weight decreases and the carbohydrate profile changes accordingly.

Q. Are GPC ingredients safe for use by patients with celiac disease?
A. GPC maltodextrins, corn syrup solids and starches are made from corn, not wheat, barley, oats or rye. Celiac patients should follow the advice of their physicians.

Q. Is maltodextrin safe for use by diabetics?
A. MALTRIN® maltodextrin’s glycemic index should be considered metabolically equivalent to glucose (dextrose). Diabetics should follow the advice of their physicians.
