Gelatin - A substitute for Xanthan Gum


Gelatin is a type of protein derived from collagen obtained from various animal body parts. This translucent, colorless, brittle (when dry), flavorless food is commonly used as a gelling agent in food, pharmaceutical drugs, vitamin capsules, photography, and cosmetic manufacturing. It used as a thickener for fruit gelatines and puddings.

The thickening, stabilizing and emulsifying agent xanthan gum added to foods such as ice cream,  cream cheese, yogurt, or salad dressing acts as as a thickening, stabilizing and emulsifying agent. However, gum substitutes are generally gel-like in consistency and are much weaker in their structure. This lack of structure, produces baked goods that are denser because they aren't able to rise as well. Besides, people who have allergic to xanthan gum or dislike their texture in baked goods may choose substitutes.

Gelatin is a water-soluble glutinous protein obtained from animal tissues, mainly pig skin. The thick jelly-like mixture used in food preparation make it acts like a sticky adhesive.

For example, if your recipe calls for 1 tbsp of xanthan gum, add 2 tbsp of gelatin. It can be added directly to the dry ingredients in its powdered form - 1 tsp per 2 ½ cups of gluten-free flour in bread recipes.
