Maltodextrins + Corn Syrup Solids
MALTRIN® maltodextrins and corn syrup solids are versatile nutraceutical ingredients. They are consistent, soluble and pure, and offer the nutraceutical industry diverse functionality and cost-effectiveness for developing new products, reformulating existing products and line expansion.

Tapioca Maltodextrins + Tapioca Syrup Solids
MALTRIN® tapioca maltodextrin and tapioca syrup solids (MALTRIN® T-Series) are the newest addition to GPC’s globally marketed MALTRIN® line of ingredients. These products are sourced from 100% tapioca, making them Non-GM by origin, and are manufactured with an all-enzyme, demineralized process. MALTRIN® tapioca maltodextrins and tapioca syrup solids are allergen free and Cronobacter free, which makes them ideal for infant nutrition formulations among numerous other applications. These new tapioca-based products can also help with clean label requirements for many customers.

PURE starches by GPC are used for binding, carrying, disintegrating, thickening and coating in a myriad of applications. Our product line provides customers the ability to choose a starch designed for their specific need.
