Hydroxypropyl Methylcellulose: The Science & The Applications
Starting at the top, what is cellulose anyway?
Cellulose is the building block of living plants. It’s made from extremely long chains of the same simple sugar, glucose (you might know it as dextrose). If you chop up the chains to their individual links, you get glucose. Nothing else. It is however, extremely difficult to do that. Bacteria can do it, which is why herbivores host bacteria in their guts to break the cellulose down into the glucose all our bodies use as our energy source. When we humans eat cellulose in whatever form (lettuce, apple, celery… methylcellulose) we can’t digest it and it goes through our bodies as a non-digestible fibre. This actually helps with the smooth working of our guts.
The cellulose used to make methylcellulose comes from living plants; trees to be precise. A regular, consistent, sustainable source; the trees that are cut down to make the cellulose pulp are grown specially and replaced.
