Carob Bean or Locust Bean Gum

Acceptable Keto Ingredient

What is Carob Bean?

Locust bean gum, also called carob gum, is a natural thickener that’s commonly added to packaged foods and has many uses in cooking and food manufacturing. Locust bean gum is extracted from the seeds of the carob tree. In many ways, this tropical tree is similar to the cacao plant, from which chocolate is made.

Locust bean gum is a fine white powder with many uses in food production. The gum is mildly sweet and has a subtle chocolate taste. However, it’s used in such small amounts that it does not affect the flavor of the products it’s added to. Locust bean gum is made of an indigestible fiber called galactomannan polysaccharides, which have a long, chain-like molecular structure. These polysaccharides give the gum its unique ability to turn into a gel in liquid and thicken foods.

It’s most commonly used as a thickener in food production, particularly in natural or organic foods that are free of highly refined ingredients.

I Heart Keto Mart Rating Guide

I Heart Keto Mart rates all ingredients through a “keto diet” & “low carb diet” lens. As an example, peas would be rated as “Acceptable” on a non-keto healthy diet; however, due to their carbohydrate level, we rate them “Objectionable”. We also rate all sweeteners that typically cause a rise in blood sugar and insulin levels as “Objectionable”. If you prefer a natural sweetener, like honey, over a sugar alcohol like erythritol, you may not agree with our “Objectionable” rating. I Heart Keto Mart rates all ingredients based first and foremost for those that have a sugar/carbohydrate addiction. Ingredients are rated for those who must moderate if not completely abstain from any sugars. If you have questions about this, please refer to this article: Why Some Whole Foods Are Not Keto Friendly


I Heart Keto Mart is not a health care provider. We are an online keto educational site that shares keto approved products and low carb products and defines and rates their ingredients. I Heart Keto Mart’s hope is that our viewers will educate themselves on “all things ingredients” so they can easily identify keto approved ingredients and eliminate or greatly restrict unacceptable keto ingredients. I Heart Keto Mart is the best online keto store and online low carb store with 1000s of products and an informative blog that shares keto articles and keto recipes, interviews keto coaches and keto product manufacturers and so much more.  We are keto affiliates and each of the keto approved products we rate is linked to the vendor’s site where the product may be purchased. I Heart Keto Mart may earn a small commission from these sales. Amazon is one of these affiliates.
