Sodium Alginate is a versatile ingredient derived from brown seaweed, renowned for its thickening and stabilizing properties. It plays a crucial role in frozen drinks by preventing the formation of large ice crystals, thereby improving texture and consistency. In addition to its anti-freeze and thaw capabilities, Sodium Alginate acts as an ice crystal inhibitor, making it ideal for frozen beverages such as smoothies, slushies, and frozen cocktails. This article explores how Sodium Alginate enhances frozen drinks, its benefits, and its applications in the beverage industry.

1. Prevents Ice Crystal Growth:
• Sodium Alginate inhibits the formation and growth of large ice crystals, which can cause a grainy or rough texture in frozen drinks. By stabilizing the liquid matrix, it ensures that ice crystals remain small and uniformly distributed, preserving a smooth and creamy texture.
2. Enhances Freeze-Thaw Stability:
• Sodium Alginate helps maintain the consistency of frozen drinks even after multiple freeze-thaw cycles. This is particularly beneficial for beverages stored for extended periods, as it ensures the product retains its original texture and flavor.
3. Thickening and Stabilizing:
• As a natural thickening agent, Sodium Alginate adds body to frozen drinks, creating a fuller mouthfeel and stabilizing ingredients like fruit purees and flavorings. This results in a well-blended, homogenous product without phase separation.
4. Maintains Smooth Consistency During Melting:
• In frozen drinks, Sodium Alginate ensures a smooth consistency as the beverage melts, preventing separation and maintaining an enjoyable texture as it transitions from frozen to liquid form.
1. Smoothies and Slushies:
• Sodium Alginate helps maintain a smooth, thick texture in smoothies and slushies, preventing them from becoming overly watery or separating during freezing and melting.
2. Frozen Cocktails and Alcoholic Beverages:
• In frozen cocktails, Sodium Alginate stabilizes the liquid mixture and prevents ice crystals from altering the consistency, ensuring a smooth sipping experience that holds up over time.
3. Ice Cream Shakes and Milkshakes:
• Sodium Alginate can be used to thicken ice cream shakes and milkshakes, enhancing their creamy texture and preventing the formation of large ice crystals that could compromise the drink’s quality.
4. Frozen Coffee and Tea Drinks:
• Sodium Alginate works well in frozen coffee and tea beverages, where it prevents phase separation and preserves a consistent texture, even as the drink melts.
5. Popsicles and Ice Pops:
• In popsicles and ice pops, Sodium Alginate inhibits ice crystal growth, creating a smoother, less icy texture that melts evenly and is more enjoyable to eat.
Sodium alginate can give ice cream and other cold drinks a smooth appearance and silky texture. Since sodium alginate can form a stable thermally irreversible gel when it meets calcium ions, this property can prevent the ice cream from becoming rough (ice crystal growth) during transportation and storage, and prevent the ice cream from deforming due to temperature fluctuations.
At the same time, this kind of ice cream has no peculiar smell when eaten, which not only increases the expansion rate but also the melting point, significantly improving the quality and efficiency of the product. Frozen milk stabilized by sodium alginate has a good taste, no stickiness and stiffness, and is sticky and hysteretic when stirred.
A good stabilizer can make ice cream and other cold foods have a smooth appearance and taste, and will not become rough during storage, and will not make people feel its presence when eating. Stabilizers can prevent the product from forming ice crystals.
Using sodium alginate instead of gelatin and starch as a stabilizer for cold foods such as ice cream can make the mixture stable and uniform, easy to stir and dissolve, and can adjust the flow during refrigeration, so that the product has a smooth appearance and dissolving performance. At the same time, it does not need to be aged, and the expansion rate is also large. The product tastes smooth, delicate, and tastes good. The dosage is lower than other stabilizers, and the general dosage is 0.1%~0.3% (mass fraction).
