Hydroxypropyl starch

E1440 carries hydroxypropyl groups, which hold water and give a clear, glossy gel - the shine on a fruit pie filling. The groups are small and few; the glucose chain underneath is the same long polysaccharide, digested to glucose in the small intestine rather than fermented in the colon.

E1440 carries hydroxypropyl groups that hold water and give a clear gel. Adding a small group to a long chain does not produce a short chain, which is the only thing this axis asks about.
