[0002] With the improvement of people's health awareness, plant protein beverages are becoming more and more popular among consumers due to their rich protein and low fat characteristics. As one of the sources of high-quality plant protein, beverages made from nuts have a rich taste and comprehensive nutrition. However, there are still some problems with the compound nut plant beverages currently on the market. On the one hand, in order to ensure stability, most products add a large amount of stabilizers and emulsifiers, which not only increases the cost but also may affect the natural flavor and health properties of the beverage. On the other hand, during the processing of some compound nut beverages, due to unreasonable processes, the nutrients of the nuts are seriously lost, and the taste and aroma are also unsatisfactory. Therefore, it is of great market significance to develop a compound nut plant beverage with good stability, rich nutrition, excellent taste and simple preparation process. Summary of the Invention

[0008] Step 4) adding xylitol, microcrystalline cellulose, and xanthan gum to the nanoscale composite slurry and stirring evenly to fully dissolve and disperse the components;

[0009] Step 5) The prepared material is fed into a colloid mill and processed for 25-35 minutes to further refine the particles and make the beverage taste more delicate;

[0010] Step 6) homogenizing the material under a pressure of 45 MPa for 15-20 minutes, for a total of two homogenizations to ensure the stability of the beverage system;

[0011] Step 7) The homogenized semi-finished composite nut beverage is sterilized by ultra-high temperature instantaneous sterilization at a temperature of 135-140° C. for 35-45 seconds, and then aseptically filled at low temperature to obtain a finished composite nut plant beverage.

[0012] Preferably, in the above-mentioned composite nut plant beverage and preparation method thereof, the pressure of the high-pressure jet nano-micro grinding is 85-95 MPa, and the time is 18-22 minutes.
