This invention relates to the field of alcoholic beverage
processing technology, and discloses a
polysaccharide compound stabilizer for improving the foam performance of low-
alcohol baijiu (Chinese
white liquor) and its application. The compound stabilizer comprises
astragalus polysaccharide, tanshinone
polysaccharide, and β-
cyclodextrin. The
mass ratio of
astragalus polysaccharide to tanshinone polysaccharide is 1:3 to 3:1, and the two polysaccharides account for more than 70% of the
solid mass of the compound stabilizer. β-
cyclodextrin accounts for more than 0% and no more than 30% of the
solid mass. The compound stabilizer is added to low-
alcohol baijiu (Chinese
white liquor) obtained by blending or reducing the
alcohol content of light-
aroma baijiu, with a final
alcohol content of 5% vol to 15% vol, at an addition amount of 15 g / 100 mL to 20 g / 100 mL. After mixing, dispersion, static stabilization, and membrane
filtration, low-alcohol baijiu with improved foam performance is obtained. This invention can increase the maximum foam height of low-alcohol baijiu and prolong the foam disappearance time, while maintaining the
clarity, suitable
viscosity, and sensory harmony of the liquor.
