In seafood and surimi, food-grade STPP helps retain colour, improve gel strength, reduce drip-loss, and maintain product stability during freezing and thawing.
2.3 Frozen Foods & Ready-to-Eat Meals
Applied in frozen prepared foods and ready-to-eat meals, STPP improves moisture retention, enhances mouthfeel, prevents syneresis, and supports longer storage stability.
2.4 Bakery, Cheese & Dairy Systems
STPP acts as a buffering and emulsifying agent in dairy-based sauces, cheese analogues, and bakery fillings—improving texture, stabilising ingredients, and enhancing shelf life.
