On Edible Gums

My motivation for writing this post is strictly self-serving. The differences between edible gums and their uses is precisely the kind of information I can never commit to memory. So, tired of searching repeatedly through the many sources of information on gums, I decided to create an easy to understand reference guide. I did it for me. And, okay, for you too.

CMC Powder

Carboxy Methyl Cellulose or SodiumCarboxyMethylCellulose. The chemical name for Tylose. (See Tylose below.)

Gum Arabic

  • Uses: stabilizer, edible gum, binder, emulsifying agent
  • For cake design: Add to royal icing to strengthen. Create edible glue (or “gum glue”) by mixing 2 tsp. gum arabic with 2 ounces water (source: SugarCraft.com)
  • Natural or synthetic: Natural
  • Alternative names: acacia gum, chaar gund, char goond, or meska
  • Most similar to: n/a

Gum Tex

Wilton brand name for karaya gum. (See karaya gum below.)

Gum Tragacenth

  • Uses: Drying agent. Adds strength and stretch.
  • For cake design: Used in making gumpaste and pastillage. Can be added to fondant to speed drying (sometimes called “emergency gumpaste“, see recipe under Tylose)
  • Natural or synthetic: Natural
  • Alternative names: gum trag, gum elect, gum dragon
  • Most similar to: Tylose

Karaya Gum

  • Uses: thickener and emulsifier, used to adulterate gum tragacenth due to their similar physical characteristics
  • For cake design: Ingredient in some gumpaste recipes. Can be added to fondant to speed drying (sometimes called “emergency gumpaste“, see recipe under Tylose)
  • Natural or synthetic: Natural
  • Alternative names: Gum-Tex (Wilton brand)
  • Most similar to:  gum tragacanth

Tylose

  • Uses:  thickener, binder, stabilizer, and suspending agent in glazes. Helps products retain moisture and gives a gum-like texture. Also acts as drying agent in fondant and gumpaste. Tylose is said to hold up better in humidity and is whiter in color. The more tylose you use, the stiffer and stronger the resulting fondant.
  • For cake design:  Ingredient in some gumpaste recipes (including the one I use, Nicholas Lodge’s gumpaste recipe). Can be added to fondant to speed drying, sometimes called “emergency gumpaste“. To create emergency gumpaste, add 2 -3 tsp of Tylose powder to 1lb of fondant. The more tylose you use, the stiffer and stronger the resulting fondant. Tylose is said to hold up better in humidity and is whiter in color than gum tragacenth.
  • Natural or synthetic: Synthetic
  • Alternative names: Super gum, cellulose gum
  • Most similar to: Gum tragacenth

    I need to make an adhesive for dentures and I got a great recipe on line using karaya gum powder and tragacanth powder. However, I am having a very hard time finding out WHERE I can bay said gum powders. I’ve tried calling health food stores and cake stores, but I am unable to find a supplier. I live in Toronto, but would consider buying online if necessary. Can you help me. I have multiple chemical sensitivities and poli-grip makes me really sick.

      Hi Kim,
      While I am not qualified to offer medical or dental advice, I will answers your questions to the best of my knowledge. Both gum tragacant (“gum trag”) and karaya gum are used in sugar paste products found and are found in cake decorating supply stores. Wilton makes a product called Gum Tex. I don’t know if it is 100% karaya gum, but I know that it is a major component. You can find Wilton products at crafts stores (Michaels, JoAnn’s) and at Walmart. I buy my tragacanth powder online at Global Sugar Art.
      Hope that helps!
      Erica
