摘　　要：本文用中空纤维式超滤膜组件对低度白酒进行了除浊澄清的应用试验。实验结果表明了孔径在３０．０００逆尔顿以上的膜只能除去酒中已经絮凝成酯粒的高级脂肪酸酯类，而对溶解状态的高级脂肪酸酯类没有截留作用，经膜处理的酒进一步稀释降度仍然会出现浑浊现象，浑浊的低度白酒降温后（５℃左右）再用膜处理可以保证在更低的温度（一１５℃以上）时酒体有较好的稳定性。化学分析说明膜对酒的总酸，总醛没有影响，而对总酯、杂醇油的含量有降低的作用，感官评品得出用孔径０．１μ的膜处理后的酒对风味几乎没有影响，但酒体的低温稳定性却得到提高。This paper describes the experiment resultS for clarifying low alcoholliquor using hollov fiber membrances. It shows that the membrance with a cut-offof 30,000 dalton molecular weight,could only remove conglomerste high fatty esterand does not effect most kind of the diSSolved ester, Ultrafiltered with the mem-brance Cartridge,the wnter diluted base liquor remains to be turbid.When theturbid liquor ultrafiltered with this membrance at 5 C,it will keep high stableclarity at low tempersture(-15 C).The total acidity and total aidehyde in theultrafiltered liquor are changed,but the level of total ester and fusel oil arelowered. It is concluded through organoleptic evaluation that the transperancystability of the liquor.at low temperature is inproved and the flavor of which isunaltered as the liquor is ultrafiltered with a membrance of 0.1 cut-off.
