Using Gums
Efficient dissolution of a gum is created by making sure that each particle is an individual entity in the mixture. Stabilizers, being highly hydrophilic (water loving), will sometimes lump or ball up when incorporated into a system. This situation can be easily overcome through any, or a combination of, the following methods.
- Pre-blend the stabilizer with a soluble dry granular or powdered ingredient such as salt or sugar. A 4:1 ratio works well.
- Initial dispersion in another liquid, such as corn syrup (in which the hydrocolloid is less soluble, avoiding lump formation)
- Make a slurry of the stabilizer with oil. As a rule, Gum Technology stabilizers are insoluble in oil, propylene glycol and alcohol. Any of these ingredients are excellent for making a slurry, which can later be incorporated into the final product.
- Add the powder slowly during high shear mixing. When adding stabilizer into a kettle, make sure that there is sufficient agitation to rapidly disperse the stabilizer. Sift the stabilizer into the mixture very slowly towards the vortex. If there is no vortex, then there is probably not enough agitation to satisfactorily disperse the stabilizer.
- An aspirating system can be extremely effective for dispersing stabilizers. The technical staff at Gum Technology will gladly advise you on specifics for setting up an aspirating system with your equipment. In general, aspirating systems are inexpensive, usually under $200.00. If available, a high speed blending system, such as a BreddoLikwifier® or Scott Turbon® mixer, will easily accomplish dispersion.
- Use an eductor system to disperse the gums.
