The functional benefits of Sodium alginate in ice cream formulations

Sodium alginate is a plant-derived hydrocolloid extracted from brown seaweed, widely valued in the dairy industry for its ability to improve texture, stability and mouthfeel. In ice cream formulations, it functions as a reliable stabilizer that enhances creaminess, reduces ice crystal growth and ensures a smooth, indulgent experience throughout storage and serving.
One of the major advantages of sodium alginate in ice cream is its ability to bind water and control ice recrystallization. This ensures that the ice cream maintains a fine, smooth texture even during temperature fluctuations. By preventing large ice crystal formation, it helps deliver a consistently creamy product that feels premium and velvety with every scoop.
Sodium alginate also plays a crucial role in improving melting resistance. It helps stabilize the air bubbles incorporated during freezing, contributing to better overrun and a stable structure. This results in ice cream that melts slowly, stays in shape longer and offers a better serving experience every time.
In addition to texture improvement, sodium alginate enhances storage stability. It prevents syneresis (wheying off), reduces shrinkage over time and maintains a uniform body throughout the product’s shelf life. These functional attributes allow manufacturers to offer ice cream with improved stability during distribution, retail display and consumer use.
