Embodiment 1

[0017] A preparation process of lettuce micropowder, comprising the following steps,

[0018] 1) Use fresh lettuce as raw material, remove impurities and clean it, put it in a fresh-keeping store at 3-5°C to drain the surface moisture, and set aside;

[0019] 2) Put the lettuce into the tumbling machine for tumbling treatment. When tumbling, vacuumize once every 5-8 minutes. After each vacuuming, tumbling for 5-10 minutes, and then evacuate, and cycle 2-4 times like this , so that the lettuce can achieve the effect of breathing massage in the process of rolling and kneading, and improve the activity of internal substances;

[0020] 3) Squeeze the lettuce after rolling and kneading, collect the lettuce juice, squeeze the juice in a vacuum environment, and control the temperature at 5-10°C;

[0021] 4) Inject lettuce juice and water into the stainless steel heating tank in a ratio of 100:10 by weight to dilute the lettuce juice, and then seal the stainless steel heating tank; ...
