Embodiment 1
[0030] A preparation method of gardenia extract, the steps are:
[0031] (1) Crushing and extraction: Take 50 kg of frozen gardenia, crush it with a stainless steel crusher and sieve through a 5-mesh standard sieve to obtain broken gardenia; put the broken gardenia into an extraction tank, and add purified water 6 times the quality of the broken gardenia. Water, under the condition of stirring, the temperature of the mixed solution is controlled at 45°C, the pH of the mixed solution is adjusted to 4.0 with a hydrochloric acid solution with a concentration of 3% by mass, and the endogenous substance released after the destruction of the self-organized structure of Gardenia jasminoides is used Sexual pectinase hydrolyzes the pectin in Gardenia jasminoides, destroys the cell wall structure to promote the release and dissolution of geniposide and genipoxanthin in Gardenia jasminoides, and continues to stir for 3 hours to enzymatically hydrolyze pectin and dissolve and extract Garde...
Embodiment 2
[0038] A preparation method of gardenia extract, the steps are:
[0039] (1) Crushing and extraction: Take 70 kg of freshly harvested gardenia, crush it with a stainless steel crusher and pass through a 3-mesh standard sieve to obtain broken gardenia; put the broken gardenia into the extraction tank, add the quality of the broken gardenia 6.5 times of purified water, in the case of stirring, the temperature of the mixed solution is controlled at 46°C, the pH of the mixed solution is adjusted to 3.9 with a hydrochloric acid solution with a concentration of 3.5% by mass, and the self-organized structure of Gardenia jasminoides is destroyed to release The produced endogenous pectinase hydrolyzes the pectin in Gardenia jasminoides, destroys the cell wall structure to promote the release and dissolution of geniposide and genipoxanthin in Gardenia jasminoides, and continues to stir for 2.5 hours to enzymatically hydrolyze pectin, dissolve and extract The active ingredients of Garden...
Embodiment 3
[0046] A preparation method of gardenia extract, the steps are:
[0047](1) Crushing and extraction: Take 130 kg of fresh gardenias preserved under controlled atmosphere, crush them with a stainless steel crusher and pass through a 1-mesh standard sieve to obtain broken gardenias; put the broken gardenias into an extraction tank, add the quality of the broken gardenias 7 times of purified water, while stirring, control the temperature of the mixed solution at 47°C, adjust the pH of the mixed solution to 3.8 with a hydrochloric acid solution with a concentration of 4% by mass, and release the The produced endogenous pectinase hydrolyzes the pectin in Gardenia, destroys the cell wall structure to promote the release and dissolution of geniposide and genipoxanthin in Gardenia, continue stirring for 2 hours, enzymatically hydrolyzes pectin, dissolves and extracts The active ingredients of Gardenia, centrifuged to obtain the first Gardenia extract and the first Gardenia residue; pu...
