[0029] The preparation process of the above-mentioned extracted antioxidant active particles is liquid, although it can be used directly and has anti-oxidation effect, but the liquid is not easy to store, transport and carry.
[0030] Therefore, in order to solve this technical problem, the embodiments of the present invention granulate the extracted antioxidant active substances to obtain granules, which are convenient for carrying and transportation. Therefore, the embodiment of the present invention also provides a preparation process of antioxidant active granules: firstly, the antioxidant active substances in lotus root are granulated according to the above-mentioned extraction method, and the specific preparation process is as follows:
[0031] S1, spray drying:
[0032]The concentrated solution obtained after the above-mentioned concentration is passed into a spray drying tower for drying to obtain extract powder. The concentrated solution is dried to remove the moistu...
Embodiment 1
[0042] This embodiment provides an extraction process for antioxidant active substances:
[0043] Wash the freshly picked lotus root, freeze it for 36 hours at -18°C, then crush it and thaw it. The thawing temperature is room temperature and the thawing time is 4 hours. The crushed lotus root was mixed with deionized water at a mass ratio of 15:1, and then homogenized at a high speed of 10000 r / min for 6 minutes. Then soak in a constant temperature water bath at 80°C for 2 hours. Then perform centrifugation to obtain a supernatant, the centrifugation speed is 3500r / min, and the centrifugation time is 5 minutes. Finally, the supernatant was concentrated, and the concentration was 4 times. That is, the extraction of antioxidant active substances is completed.
[0044] This embodiment also provides a preparation process of antioxidant active particles:
[0045] Spray-dry the concentrated solution obtained above to obtain extract powder. The specific spray drying tower has an ...
Embodiment 2
[0047] This embodiment provides an extraction process for antioxidant active substances:
[0048] Wash the freshly picked lotus root, freeze it for 48 hours under the condition of -24°C, then crush it, and thaw it. The thawing temperature is room temperature, and the thawing time is 6 hours. The crushed lotus root was mixed with deionized water at a mass ratio of 10:1, and then homogenized at a high speed of 14000 r / min for 8 minutes. Then soak in a constant temperature water bath at 90°C for 4 hours. Then perform centrifugation to obtain a supernatant, the centrifugation speed is 4000r / min, and the centrifugation time is 8 minutes. Finally, the supernatant was concentrated, and the concentration was 3 times. That is, the extraction of antioxidant active substances is completed.
[0049] This embodiment also provides a preparation process of antioxidant active particles:
[0050] Spray-dry the concentrated solution obtained above to obtain extract powder. The specific spra...
