Title: Verfahren zur Herstellung von sterilisierter und veredelter Kakaomasse und von Milchschokolade unter Verwendung der Kakaomasse
IPC: A23G1/10
Filed: 1983-08-31
Granted: 1986-12-04
Abstract: Vorliegende Erfindung betrifft ein Herstellungsverfahren von Milchschokolade geringer Keimzahl, charakteristischen Geschmacks und reduzierter Conchierdauer. Sie besteht aus einer ersten Stufe zur Sterilisation und Veredelung der Kakaomasse in einem Vakuumknetmischer, unter bestimmten Feuchtigkeits-, Temperatur- und Vakuumbedingungen. In der zweiten Stufe, die ebenfalls unter bestimmten Temperatur- und Vakuumbedingungen verläuft und bei der die in der ersten Stufe verarbeitete Kakaomasse mit Milchpulver in dem Vakuumknetmischer vermischt wird, werden unerwünschte leichtflüchtige Stoffe und Feuchtigkeit aus dem Milchpulver entfernt und der durch die MAILLARD-Reaktionen hervorgerufene, charakteristische Geschmack entwickelt.  Nach den durchgeführten Experimenten ergibt die obenbeschriebene Verarbeitung eine praktisch sterilisierte Kakaomasse (T.P.C. = 50/g), die auch zur Herstellung anderer Kakaoprodukte benutzt werden kann. Das Endprodukt (die Milchschokolade) zeigt einen T.P.C.-Wert von 2900/g und hat einen charakteristischen, angenehmen Karamelgeschmack.  Außerdem wird die Dauer der am meisten energieverbrauchenden, unentbehrlichen Stufe des Conchierens bei der Herstellung von Milchschokolade auf die Hälfte reduziert.
