Outline of Final Research Achievements

Sugar alcohol method as a main material of Lactitol which has been researched past, in order to shift to a more Trehalose method which is excellent in stability, workability, firstly grasps the crystals of the characteristic to be generated Trehalose, under various conditions repeat crystal generation test, it was pursuing its reproducibility. Furthermore, to perform impregnation and crystallization test using the test piece was established three methods of controlled temperature ,called "heating ", "cooling ", "non-controlled ".
Based on the above test results, given the amount of crystals required by the wooden cultural properties, setting the final impregnation concentration, and to select crystallization technique, it revealed that it is completed conservation treatment efficiently and without waste.
