The invention provides a purple sand sintered body for
wine aroma enhancement and a preparation method and application thereof, and belongs to the technical field of purple sand materials.The purple sand sintered body for
wine aroma enhancement is prepared by mixing Benshan purple clay purple sand pug and Benshan
cinnabar clay purple sand pug according to the
mass ratio of (95-60): (5-40) and firing, the content of TiO2 in the mountain purple clay purple sand pug is not less than 0.9 wt.%; the K2O content in the mountain
cinnabar clay purple sand pug is not less than 2.0 wt.%, and the MgO content is not less than 0.6 wt.%. According to the purple sand sintered body for
wine aroma enhancement, other preparations do not need to be additionally added, only the natural Benshan purple clay purple sand mud rich in
titanium and the Benshan
cinnabar clay purple sand mud rich in
potassium and
magnesium are mixed, and an iron-based multi-element catalytic
system is constructed by adjusting the
mass ratio of the two materials. Furthermore, a
sintering process is optimized, a confinement space is created, and the synergistic effect of the multi-element
metal catalyst is enhanced, so that the generation efficiency of the wine
flavor substance is remarkably improved.
