Milky tea solid beverage prepared from ultra-micro broadleaf holly leaf powder and preparation method thereof

The invention provides a milky tea solid beverage prepared from ultra-micro broadleaf holly leaf powder. The milky tea solid beverage contains the ultra-micro broadleaf holly leaf powder, milk powder and soluble soybean polysaccharide. According to the invention, the prepared ultra-micro broadleaf holly leaf powder, milk powder and soluble soybean polysaccharide are prepared into a solid fruit tea under a specific condition. The integrated innovations of the technique according to the invention are as follows: the tea leaf raw material is refrigerated and treated with dry ice, so that the loss of the thermal sensitive nutritional ingredients in the tea leaves caused by the thermodynamic effect in an ultra-micro smashing process can be reduced or avoided; the dry ice is remained in the pores of the ultra-micro broadleaf holly leaf powder grains, so that the tea powder can be stored for a long time; the soluble soybean polysaccharide and the high-pressure homogenizing treatment are beneficial to the stability o
