The taste of this material is basically the same as that of Diacetyl, but it is much weaker, a fact which is often translated as 'milder'.
The product is intended for use in flavor compositions, where a milder Diacetyl-effect is desirable, and greater stability necessary.
Produced from 2 moles of Glycerin plus 1 mole of Diacetyl by condensation and removal of 2 moles of water.
