Choosing between high acyl gellan gum and low acyl gellan gum depends on the specific application and desired characteristics of the final product. Here are some factors to consider when deciding which type to use, especially for a new customer:

  1. Gel Texture and Firmness:

    • -High Acyl Gellan Gum: It tends to form softer and more elastic gels. If you want a gel with a delicate texture, high acyl gellan gum might be more suitable.

    • -Low Acyl Gellan Gum: It forms firmer and more brittle gels. If you require a gel with a firmer texture, low acyl gellan gum might be the better choice.

  2. Temperature Stability:

    • -High Acyl Gellan Gum: Generally exhibits better stability over a broader range of temperatures. It is suitable for applications where the product might undergo temperature variations.

    • -Low Acyl Gellan Gum: May be more sensitive to temperature changes. If the product will be subjected to consistent temperature conditions, this may not be a significant factor.

  3. Syneresis (Water Release):

    • -High Acyl Gellan Gum: Tends to have lower syneresis, which means it releases less water. This can be important in applications where maintaining a certain level of moisture is crucial.

    • -Low Acyl Gellan Gum: May have higher syneresis, so water release might be more noticeable. Consider this if water retention is a critical factor in your application.

  4. Processing Conditions:

    • -High Acyl Gellan Gum: Typically more forgiving in terms of processing conditions. It can be easier to work with in a variety of applications.

    • -Low Acyl Gellan Gum: Might require more precise conditions during processing. If your production process allows for careful control of parameters, this may not be an issue.

  5. Application-Specific Considerations:

    • Consider the specific requirements of your product, such as pH, sugar content, and the presence of ions. Different gellan gum types may have varying sensitivities to these factors.

  6. Consult with Suppliers:

    • Reach out to gellan gum suppliers or manufacturers for guidance. They often have technical support teams that can provide valuable insights based on your specific application.

For a new customer, it's advisable to start with small-scale trials and experiments to determine the best type of gellan gum for your particular needs. Additionally, consider seeking advice from experts or conducting compatibility tests in your specific formulation.
