The hemicellulase enzyme breaks down hemicellulose, which is a type of cellulase and a key component of the cell wall in all plants. Different forms of plant hemicellulose include glucans, galactans, xylans, mannans and pentosans. Common fiber-rich breakfast cereals, for example, have a large amount of hemicelluloses (2 to 12%). Hemicellulase is needed to break down these fiber-rich components, and because it is not produced naturally in the human body, we rely on microorganisms that live in the human digestive tract to produce it for us.
The hemicellulase enzyme has the ability to take non-cellulose polysaccharides (long chains of sugars) we eat and convert them into usable constituents. Hemicellulase, which is crucial for the breaking down of fruits, vegetables and many grains is required to break down the “hard” hemicellulose carbohydrates, which are known to slow digestion and the absorption of various nutrients. If we eat large amounts of plant material, but do not have enough hemicellulase, we get a very limited prebiotic intake. These prebiotics are composed of smaller indigestible saccharide units that serve as fuel for various types of probiotics (good bacteria) resident in the digestive tract.
