What is Chitin?

Chitin is the fibrous material that makes up the exoskeleton of arthropods such as insects and crustaceans.


Edible insects all use the fibrous material chitin to form the structure of their exoskeletons. Chitin can be found in the exoskeleton of insects, the shells of crustaceans, and even in the wing scales of a butterfly!

There are different modified versions of chitin that are utilized throughout the insect world that make it possible to have the strong exoskeleton of a beetle for example, and also be used to create the flexible bodies seen in caterpillars.

For those that are interested in entomophagy and eating insects, the chitin is also a great source of valuable fiber and a prebiotic too.

Wondering what is entomophagy?

It generally refers to the human consumption of insects as a food source


Edible insects as a roasted snack or protein powder are a great source of nutrients and protein.  However they are also a source of beneficial fiber from the chitin that is a great prebiotic for gut health.

In a recent study on the consumption of edible insects, the researchers found almost a 6X increase of probiotic bacterium, Bifidobacterium animalis, and may systemic inflammation too. The prebiotics available from the chitin in edible insects, provide nutrition for probiotics and are one of the benefits of chitin for gut microbiology. Read more about the study in depth here.

Chitin also provides an available source of dietary fiber.  The dietary fiber is good for your digestive health and helps to keep you feeling full longer, and has also been found to help to improve cholesterol and blood sugar levels.
