✦ Synopsis

I) The small quantity of colloids present in lemon juice does not affect crystallization, but the ash and other non-acid constituents prevent satisfactory crvstallization of concentrated fermented juice.

(2) In the presence of ash and other impurities, needle and leaflet modifications of citric acid crystals are obtained: upon the removal of half of the ash, characteristic citric acid crystals are formed.

(3) At the concentration necessary for crystallization, the mother liquor is so viscous that the crystals cannot be separated.
