2. Applications in Food Processing

2.1 Processed Meats & Poultry

STPP is used in sausages, hams, and marinated poultry to enhance water-holding capacity, improve texture and firmness, reduce cooking loss, and maintain juiciness.

2.2 Seafood & Surimi Products

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.
