Extraction method for medicinal and edible 1-5 micron nano active extraction liquid

The invention relates to an extraction method of 1-5 micron nano active extract liquor for homology of medicine and food. The extraction method comprises the following steps: classifying and cleaning leaves, flowers and plants of fresh traditional Chinese medicines for homology of medicine and food; the plants are cut into blocks or smashed; drying the leaves and flowers by using a fluid bed dryer; carrying out degradation through ultrasonic waves; organic or water extraction; carrying out homogenization treatment; passing through a concentration evaporator; wrapping with a nano microcapsule; spraying or freeze-drying the extract powder of the extract; the efficient extraction and characteristic control of the extract are the basis of effective component purification; purifying the extract; the extract is subjected to micro-phase separation at the nanoscale, so that impurities are effectively removed; micro-nanocrystallization of the particles is realized by an external force field in the drying process; high
