20.500.12556/DKUM-55233 Pilotna raziskava izluževanja Taninskega ekstrakta iz pravega kostanja (Castanea sativa mill.) Pilot studies of leaching tannin extract from chestnut tree (Castanea sativa) Namen našega dela je bil ugotoviti povezavo med količino dodanega NaOH v demineralizirano vodo za izluževanje in kvaliteto, ter količino ekstrakta. V demineralizirano vodo smo po preračunu dodajali po 1, 2,5 in 4 grame NaOH glede na količino suhega lesa, ki smo ga izluževali. Ugotovili smo, da kakovost in količina ekstrakta raste ob dodatku 1 grama vse do 2,5, kjer doseže vrh in nato spet pada proti 4 gramih NaOH. The aim of our work was to determine the correlation between the quantity of added NaOH in demineralized water for leaching, and the quality and quantity of the extract. We added NaOH in demineralised water in 1, 2.5 and 4 grams of NaOH according to the quantity of dry wood, which has been extracted, grams of NaOH per dry wood. We have found that the quality and the quantity of extract grows with the addition of 1 gram up to 2.5, where it reaches the top. Quality and quantity then starts falling down with the addition of 4 grams of NaOH per dry wood.
