[目的]了解国产东易鱼胶(DOEST)在干红葡萄酒中的下胶效果.[方法]以2011年烟台产区赤霞珠、蛇龙珠、梅鹿特干红原酒为试样,首先以透光率、澄清度及热稳定性为依据确定鱼胶在干红葡萄酒中适宜的下胶浓度,然后再与明胶、蛋清、皂土进行下胶效果的综合比较.[结果]东易鱼胶(DOEST)在干红葡萄酒中使用浓度在40～60 mg/L时可获得令人满意的澄清效果,下胶综合效果可与蛋清相近,优于明胶和皂土.[结论]研究为国产东易鱼胶(DOEST)在干红葡萄酒下胶中的应用提供了参考.%[Objective] To understand the clarifying effect of domestic produced fish glue (DOEST)in dry red wine. [Method] The Cabernet saiwignon, Cabernet gemischl and Merlot red wine produced in Yantai were sampled, the most appropriate concentration of fifih glue was determined based on the Iransmillance, clarifying degree and thermostafaility; and the clarifying effect of fish glue was compared with thai of glutin, eggwhite and bentonite. [ Result] Satisfactory clarifying effect could be obtained at the concentration of 40 -60 mg/L fish glue, and the clarifying effect was close to that of eggwhile and better than that of glutin and bentonite. [Conclusion] The study provides references for the application of DOEST in the clarifying of dry red wine.
