What is Corn Maltodextrin?

Corn maltodextrin is a polysaccharide that is derived from corn starch. It is created by partially hydrolyzing corn starch, which breaks the long chains of glucose molecules into smaller chains.

It is used primarily as a thickener, filler, or as a way to add bulk to processed foods and beverages without significantly impacting taste. In terms of health, evidence suggests that it can cause a rapid spike in blood sugar levels due to its high glycemic index. However, its impact on health is generally seen as less concerning than more heavily scrutinized additives.

When you see corn maltodextrin on a label, know it’s a common ingredient in packaged and processed foods. It’s approved for use in most countries and is generally recognized as safe when consumed within reasonable limits.

Commonly found in: energy drinks, protein powders, soup mixes, baked goods, confectioneries
