Gellan Gum could be used in a wide pH range, especially in acid conditions, gellan gum has unique advantages than xanthan gum and carrageenan. If applied gellan gum in MILK BEVERAGES, it would help to avoid fruits pulps / cubes dropping down or having lumps and the mouth feel is excellent.
High Acyl Gellan Gum is of high viscosity in water after dissolving and the solution is not as clear as that from Low Acyl Gellan Gum. While high acyl gellan gum is not so sensitive to kations as low acyl gellan gum and high acyl gellan gum is not easy to be active with proteins. So high acyl gellan gum is always applied in Milk/Dairy products, neutral plant protein beverages and acid fresh fruit/vegetable juices. The main function for high acyl in those beverages is to be as stabilizer to keep particles or fruits cubes suspending.
High Acyl Gellan Gum HAM:This type of gellan gum could be applied in milk/dairy beverages such as soybean milk. The beverages or foods don't need transparent system. High Acyl Gellan Gum HAM would help to suspend insoluble particles and keep the final products stabilizing (acid milk beverages should combine CMC or Guar Gum to protect protein).The recommended dosage for High Acyl Gellan Gum is 0.03%.
Instructed Steps in Actual Application:
1.Mix Gellan Gum HA and 50% of water;
2.Disperse the gellan gum in the cold water by stirring;
3.Heat at 90℃ for 10 minutes for 100% dissolving of gellan gum in water;
4.Add 50% of pure soybean milk to solution 3;
5.Cool down to 25℃.
Part II: Remarks:
1.Materials without salts can be directly added into water together with gellan gum.
2.Materials with salts(or kations) should be added only when gellan gum is thoroughly dissolved.
3.The water used should be deionized water.
4.The application of gellan gum should be in addition with KATIONS( Ca, Mg, Cl, and so on).
5.Gellan Gum is soluble in cool water but need to heat up to 85℃-90℃ for thoroughly dissolving.
6.The dosage of gellan gum should be adjusted according to pH, materials added and particle sizes of fruit pulps. The higher dosage, the better performance.
