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...

Abstract

The invention discloses a preparation method of a gardenia extract, which comprises the following steps: (1) carrying out crushing, primary enzymolysis extraction and secondary water extraction on fresh gardenia to obtain a gardenia water extracting solution; (2) precipitating the water extract of cape jasmine by calcium ions under an alkaline condition to remove impurities, so as to obtain an alkaline precipitate and an alkaline supernatant; (3) adjusting the pH of the alkaline supernatant, and removing impurities to obtain a subacid precipitate and a subacid supernatant; (4) mixing the alkaline precipitate and the subacid precipitate, adding water to wash the precipitate, and adjusting the pH value to obtain a subacid washing solution; and (5) performing nanofiltration impurity removal and drying: combining subacid supernatant and subacid washing, carrying out secondary nanofiltration impurity removal and concentration, and drying to obtain the gardenia extract product. The method is low in cost, sufficient in impurity removal, high in product purity, good in environmental friendliness, low in energy consumption and high in extraction utilization rate.

Description

technical field [0001] The invention relates to the technical field of plant natural product food processing, and more specifically relates to a preparation method of gardenia extract. It is suitable for the preparation of extracts, and is also suitable for the extraction of gardenia pectin, geniposide and saffron (crocin) and the development of health food with active ingredients of gardenia as one of the raw materials. Background technique [0002] Gardenia (scientific name: Gardenia jasminoides Ellis) aliases: yellow gardenia, mountain gardenia, white toad, is the fruit of the Rubiaceae plant gardenia. Gardenia, bitter and cold in nature and taste, enters the heart, lung, stomach and other meridians, and has the function of purging the heart and relieving restlessness. It is a traditional Chinese medicine and belongs to the first batch of medicinal and edible resources promulgated by the Ministry of Health. , sedation, hemostasis, swelling and other effects. In traditio...
