The Adsorption Properties of Macroporous Resin for Fusel Oil of Luzhou-Flavor Liquor

摘要

The D3520 resin was suited for adsorption and desorption of fusel oil by the comparison study of different types of resin. The study confirmed that macro-porous resin D3520 had favorable adsorption and desorption capability by comparing different resins based on adsorption quantity, adsorption rate, and desorption rate. Temperature affected the fusel oil adsorption rate of D3520 and with more impact the temperature was high. There was little difference in the adsorption rate at 25 and 30 °C and the rate was up to 58.85 %. Among all strippant, the effect of acetone was higher than all concentration ethyl alcohol, up to 65.80 %. After treatment by D3520, there was little difference in physical, chemical, and sensory indexes of Luzhou flavor liquor and was not a bad influence on Luzhou flavor liquor. The Luzhou flavor liquor was soft and well balanced, with more rich ester aroma, and the wine quality was better by the D3520 resin treatment.
