Abstract

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 of the solid beverage in a brewing process; different from the tea soup or tea juice extracted from the tea leaves as raw material, the ultra-micro tea powder is directly used for preparing the milky tea, so that the nutritional ingredients in the tea leaves can be fully maintained, and meanwhile, the extraction process is reduced, so that the production cost is lowered.

Description

technical field [0001] The invention belongs to the technical field of deep processing of tea, and in particular relates to a milk tea solid beverage made by using superfine Kuding tea powder and a preparation method thereof. Background technique [0002] Traditional tea is mainly drunk by brewing, the utilization rate of active ingredients in tea is low, and a large amount of biochemical active substances remain in the tea dregs and are discarded. The ultra-fine tea powder maintains the integrity and functional activity of tea nutrients, the specific surface area and porosity of the powder particles increase, and the dissolution amount and dissolution rate of the contained ingredients also increase accordingly; its particle size is small, and the tea contained in it Functional ingredients such as polyphenols, theanine, and tea polysaccharides are easily absorbed by the human body, and their nutritional value is much higher than that of brewed tea. For example, a certain am...
