Embodiment 1
[0023] A method for preparing crocetin from gardenia, specifically comprising the steps of:
[0024] 1) Pre-wet stacking: build a pile of gardenias in a cool place, spray water, wait for the water to flow out from the bottom of the pile, and stack them naturally for 1 day;
[0025] 2) Raw material treatment: crush the gardenia obtained in step 1), add purified water equivalent to 2-3 times the weight of the raw material, heat to 50°C for 5 minutes, and obtain a paste-like slurry;
[0026] 3) Enzymolysis for the first time: the paste slurry obtained in step 2) is adjusted to pH 4, and 0.05% by weight of the paste slurry is added with an activity of 10,000 activity units / gram of pectin-cellulose compound enzyme and 0.001 wt. Part of mannitol was enzymolyzed for 40 minutes to obtain the first enzymolysis solution;
[0027] 4) Oil removal: add 2 times the weight of pure water to the first enzymolysis solution obtained in step 3), heat to 60°C and extract for 120 minutes to obtain...
Embodiment 2
[0032] A method for preparing crocetin from gardenia, specifically comprising the steps of:
[0033] 1) Pre-wet stacking: build a pile of gardenias in a cool place, spray water, wait for the water to flow out from the bottom of the pile, and stack them naturally for 1 day;
[0034] 2) Raw material processing: crush the gardenia obtained in step 1), add purified water equivalent to 2-3 times the weight of the raw material, heat to 60°C for 8 minutes, and obtain a paste-like slurry;
[0035] 3) Enzymolysis for the first time: adjust the pH of the paste slurry obtained in step 2) to 4.5, add 0.1% by weight of the paste slurry with an activity of 20,000 activity units / ml of pectin-cellulose compound enzyme and 0.001 wt. part of mannitol was enzymolyzed for 50 minutes to obtain the first enzymolysis solution;
[0036] 4) Oil removal: add 3 times the weight of pure water to the first enzymolysis solution obtained in step 3), heat to 70°C and extract for 60 minutes to obtain a mixtu...
Embodiment 3
[0041] 1) Pre-wet stacking: build a pile of gardenias in a cool place, spray water, and stack them naturally for 2 days after the water flows out from the bottom of the pile;
[0042] 2) Raw material treatment: crush the gardenia obtained in step 1), add purified water equivalent to 2-3 times the weight of the raw material, heat to 55°C for 10 minutes, and obtain a paste-like slurry;
[0043] 3) Enzymolysis for the first time: adjust the pH of the paste slurry obtained in step 2) to be 5, add 0.08% by weight of the paste slurry with an activity of 30,000 activity units / gram of pectin-cellulose compound enzyme and 0.001 wt. part of mannitol was enzymolyzed for 60 minutes to obtain the first enzymolysis solution;
[0044] 4) Oil removal: add 2 times the weight of pure water to the first enzymolysis solution obtained in step 3), heat to 65°C and extract for 100 minutes to obtain a mixture of the upper layer floating oil liquid, the lower layer liquid and the slag;
[0045] 5) Se...
