Emulsifiers and stabilizers for soy drinks

    Soy drinks are typically long-life beverages with a minimal amount of soy protein per serving. These products are positioned as nutritious, sweet-tasting beverages competing against soft drinks rather than as milk alternatives.

    Making a crucial difference

    Alongside UHT technology and proper homogenization to extend shelf-life, emulsifiers and stabilizers are crucial, especially for chocolate soy beverages. The right emulsifiers ensure optimal emulsion stability, reducing creaming during the entire shelf-life, while stabilizers improve the stability of proteins to minimize sedimentation during storage.

    Palsgaard provides blended and integrated emulsifiers and stabilizers for use in soy beverages. These offer advantages such as:

    • no dust formation during handling
    • 100% uniform composition
    • dispersibility at low temperatures
    • no requirement for pre-blending
    • free-flowing properties

    Adding stabilizers imparts thickening and stabilizing properties, helping to create the network needed to suspend particles, increase viscosity and improve mouth-feel. A variety of stabilizers are available for soy drinks, including carrageenan, pectin, gellan gum and microcrystalline cellulose (MCC). The latter is mainly used with chocolate soy drinks.

    Successful dosage

    Achieving the right dosage is a vital parameter for success with your soy drinks. Under-dosing or unsuitable emulsifier/stabilizer combinations cause sedimentation, while over-dosing will cause separation and/or gelation.

    Chocolate milk challenges

    Creating a stable chocolate soy beverage is more difficult that a chocolate milk as it contains more fibres. A standard carrageenan system, for example, isn't good enough to hold the cocoa particulates. Another important factor on the stability of the end product is the filling temperature. Palsgaard has developed emulsifier and stabilizer combinations suited for filling temperatures both above and below 30 degrees Celsius as well as other solutions that enable you to create refreshing soy drinks that can be flavoured with juice concentrate such as orange, apple, mango and more, depending on local tastes and preferences. 

    For use in soy beverages Palsgaard has developed Palsgaard® RecMilk 122, which interacts with soy proteins, making the fat globule membrane more resistant towards coalescence.

    Palsgaard® RecMilk 122:

    • facilitates the formation of a stable emulsion
    • maintains good creaminess and mouth-feel
    • improves the texture of the recombined soy milk and related products
