Embodiment 1
[0036] a. Take 5000g of frozen bovine purple eye (or fresh bovine purple eye), thaw, wash and then crush to 40-60 mesh, add 50g papain and mix well, pour into the fermentation tank, adjust the pH value to 5.0-7.0, The fermentation temperature is controlled at 40-50 °C for enzymatic hydrolysis. After 2 hours of enzymatic hydrolysis, the enzymatic hydrolysis material of bovine purple eye is put into supercritical CO. 2 Extraction in the extraction device, open the carbon dioxide valve to inflate, the extraction temperature is 31-39°C, the pressure is 7-10MPa, the CO 2 At this temperature and pressure, it enters the supercritical state to form CO 2 Supercritical fluid, after 60 minutes of extraction, the CO is turned off 2 Intake valve, after decompression and temperature rise, supercritical CO 2 fluid becomes gaseous CO 2 , recovering CO 2 Then, the extracted bovine purple eye enzymolysis extract is completely or basically precipitated, and then the extracted bovine purple e...
Embodiment 2
[0044] Embodiment 2: The difference between this embodiment and Embodiment 1 is that,
[0045] a. Take 6000g of frozen bovine purple eye (or fresh bovine purple eye), thaw, wash and then crush to 40-60 mesh, add 60g papain and mix well, pour into the fermentation tank, adjust the pH value to 5.0-7.0, The fermentation temperature is controlled at 40-50 °C for enzymatic hydrolysis. After 2 hours of enzymatic hydrolysis, the enzymatic hydrolysis material of bovine purple eye is put into supercritical CO. 2 Extraction in the extraction device, open the carbon dioxide valve to inflate, the extraction temperature is 31-39°C, the pressure is 7-10MPa, the CO 2 At this temperature and pressure, it enters the supercritical state to form CO 2 Supercritical fluid, after 60 minutes of extraction, the CO is turned off 2 Intake valve, after decompression and temperature rise, supercritical CO 2 fluid becomes gaseous CO2 , recovering CO 2 Then, the extracted bovine purple eye enzymolysis ...
Embodiment 3
[0051] Embodiment 3: The difference between this embodiment and Embodiment 1 is that,
[0052] a. Take 7000g of frozen bovine purple eye (or fresh bovine purple eye), thaw, wash and then crush to 40-60 mesh, then add 70g papain and mix well, pour into the fermentation tank, adjust the pH value to 5.0-7.0, The fermentation temperature is controlled at 40-50 °C for enzymatic hydrolysis. After 2 hours of enzymatic hydrolysis, the enzymatic hydrolysis material of bovine purple eye is put into supercritical CO. 2 Extraction in the extraction device, open the carbon dioxide valve to inflate, the extraction temperature is 31-39°C, the pressure is 7-10MPa, the CO 2 At this temperature and pressure, it enters the supercritical state to form CO 2 Supercritical fluid, after 60 minutes of extraction, the CO is turned off 2 Intake valve, after decompression and temperature rise, supercritical CO 2 fluid becomes gaseous CO 2 , recovering CO 2 Then, the extracted bovine purple eye enzym...
