The Gel Application of Low-Acyl Gellan Gum

Low-acyl gellan gum, as a gelling agent, is primarily used in water-based gel systems such as jelly, jam, and candy, where its main function is to form gels. The recommended usage is between 0.1% and 0.5%.

Gellan gum can form gels with various textures, ranging from elastic to brittle, and it allows for the control of the melting point to produce heat-irreversible gels. Therefore, gellan gum can create a wide variety of gel products, such as jelly, even with very low usage amounts. It is especially popular in the production of multi-layer jellies with different colors. By using oil-soluble food colors and flavorings, multi-colored jellies with different hues (such as red, green, yellow, white) and flavors can be produced without color mixing or flavor cross-contamination.

Product Features of Low-Acyl Gellan Gum for Gels:

• High gel strength;
• High transparency;
• Good solubility;
• Good heat stability;
• Low viscosity in the gel, offering a pleasant mouthfeel and excellent flavor release;
• Compatibility with other hydrophilic colloids, allowing for the achievement of different texture characteristics.

Usage Instructions for Low-Acyl Gellan Gum in Gels:

This product can be easily dispersed into water-based systems using common mixing equipment. A typical application process is as follows:

1. Disperse the gellan gum, either alone or mixed with other auxiliary ingredients, into cold water by stirring (adding a chelating agent can help the gum dissolve more effectively).
2. Heat the mixture to above 85℃ to dissolve.
3. Add cations.
4. Cool the mixture to form a stable gel system.

Application Formula for Low-Acyl Gellan Gum in Soft Candies (For Reference Only):

With the decreasing popularity of gelatine-based soft candies in the market, gellan gum, as a natural hydrophilic colloid, not only aligns with the green and healthy consumer trends but also offers distinct advantages in terms of texture and cost.

Basic Formula:

Low-Acyl Gellan Gum (LG): 0.3%, Xanthan Gum: 1%, Konjac Gum: 0.5%, Sodium Citrate: 0.1%, Calcium Lactate: 0.1%, Citric Acid: 0.05%, Maltose Syrup (75% concentration): 40%, Granulated Sugar: 30%, Fruit Juice: appropriate amount, Other auxiliary ingredients and additives as needed, Water to 100%

Production Process:

1. Mix the gellan gum, xanthan gum, konjac gum, and salt evenly.
2. Add the mixture into deionized water while stirring, then heat to dissolve the gums.
3. Combine the maltose syrup and granulated sugar, heat, and dissolve, then add the dissolved gum mixture into the syrup.
4. Add citric acid, fruit juice, and other additives, maintaining the mixture at a warm temperature until the total sugar concentration reaches around 70%.
5. Pour into molds, age, and cool.

Application Formula for Low-Acyl Gellan Gum in Solid Air Fresheners (For Reference Only):

Due to its high gel strength, transparency, excellent water retention, and flavor release properties, gellan gum has great potential for use in air fresheners. Additionally, its heat-resistant and stable irreversible gel characteristics make it ideal for such applications.

Basic Formula:

Low-Acyl Gellan Gum (LG): 0.5%, Calcium Lactate: 0.05%, Emulsifier (Tween): appropriate amount, Fragrance: appropriate amount, Colorant: appropriate amount.

Production Process:

1. Mix the gellan gum with calcium lactate.
2. Add the mixture into deionized water while stirring, then heat to dissolve the gel.
3. Pre-dissolve the emulsifier and fragrance, then add the appropriate amount of colorant.
4. Pour into molds and cool to form the solid air freshener.
