Noun[edit]

hemicellulose (plural hemicelluloses)

    • 2004, Harold McGee, chapter 5, in On Food and Cooking: The Science and Lore of the Kitchen, Scribner, →ISBN:
      The changes in texture that occur during ripening and cooking result from changes in the cell-wall materials, in particular the cement carbohydrates. One group is the hemicelluloses, which form strengthening cross-links between celluloses. They are built up from glucose and xylose sugars, and can be partly dissolved and removed from cell walls during cooking.
