Sodium Acid Pyrophosphate E450i

Product Overview

Sodium Acid Pyrophosphate (E450i) is a food-grade leavening agent and pH regulator widely used in bakery, seafood, and processed food industries. It helps control leavening speed, improves texture, and maintains colour stability in a variety of food formulations. DextroDelight offers high-purity SAPP 28 FG, providing consistent performance and fine particle size for optimal dispersion in dry blends and dough systems.

This ingredient complies with FCC and USP food-grade standards, ensuring safety, reliability, and compatibility with clean-label production processes.

Applications in Food Production

• Bakery & Dough Systems: Acts as a controlled-release leavening agent in cakes, pancakes, and muffins. Provides consistent rise and improved crumb structure when used with sodium bicarbonate.
• Processed Meats & Seafood: Enhances water-binding capacity and texture in sausages, hams, and seafood. Prevents discolouration and maintains natural meat pigments during storage.
• Potato & Vegetable Processing: Prevents greying and oxidation in par-fried or dehydrated potato products. Stabilises colour and texture during blanching and frying.
• Confectionery & Snack Foods: Used in instant mixes and fried snacks to control pH and improve crispness. Contributes to balanced flavour and extended shelf stability.
• Dairy & Ready Meals: Acts as a sequestering and emulsifying agent in processed cheese, sauces, and instant foods. Maintains smooth consistency and prevents separation under heat.
