fecula

With this fecula was mingled a mucilaginous juice of disagreeable flavor, but which it would be easy to get rid of by pressure.

A flavorless powdered starch used for this purpose is a fecula (from the Latin faecula, diminutive of faex meaning "dregs").

Tapioca (or fecula), essentially a flavorless, starchy ingredient produced from treated and dried cassava (manioc) root, is used in cooking.

The engineer constructed a press, with which to extract the mucilaginous juice mingled with the fecula, and he obtained a large quantity of flour, which Neb soon transformed into cakes and puddings.
