Sectional extraction technology of high-concentration BITC Carica papaya oil

The invention relates to a sectional extraction technology of high-concentration BITC Carica papaya oil. The sectional extraction technology comprises the following steps: (1) cleaning and drying of araw material; 2, crushing of the raw material; (3) pretreatment; (4) low-temperature refrigeration; (5) filling and sealing; (6) ultrahigh-pressure wall breaking treatment; (7) heat preservation treatment; and (8) filtering and rectifying. Sectional rectification is innovatively used in the rectification process, the extraction of the high-concentration BITC Carica papaya oil is completed by utilizing a sectional type rectification system, the concentration and activity of extract are ensured by low-temperature refrigeration, due to high-pressure treatment, a solvent can permeate into the extracted substance in an extremely short time to rapidly achieve dissolving balance of effective components, and the rectification is thorough in the sectional rectification mode, sothe high-concentration BITC Carica papaya oil
