2.Specific Applications in Food Processing
Meat & Poultry
Improves water retention and yield, enhances slicing performance, stabilizes proteins,
reduces cooking loss, and maintains juiciness in ham, sausage, and marinated poultry.
Seafood Processing
Helps prevent moisture loss and color change during freezing/thawing, reduces drip loss,
and supports texture stability for shrimp, fish, and surimi products.
Noodle & Dairy Systems
Enhances noodle elasticity and bite, supports buffering/emulsification,
and helps prevent separation in certain dairy-based sauces and formulations.
Note: Usage levels must follow local regulations and your formulation requirements.
