Embodiment 1

[0062] Steamed Polygonatum

[0063] (1) Remove impurities and fibrous roots from fresh Rhizoma Polygonatum, wash and dry in the air for 24 hours, put it in a 40°C oven and dry it for 24 hours to make its moisture content reach 25%, take out and cut thick slices of 6-8mm, and then dry it in a 40°C oven for 24 hours , so that its moisture content reaches 19%.

[0064] (2) Slice Polygonatum dried in step 1, put it in a steaming container, steam for 6 hours, and take it out. Dry it with hot air at 65°C for 16 hours until the water content is 17%, and then you can get steamed and sun-dried Polygonatum.

[0065] (3) Repeat the operation of step 2 above four times to obtain five-steamed and five-sunned Polygonatum. Control the water content of Polygonatum 16% after steaming and drying for the second time, 14% for the third time, 12% for the fourth time, and 10% for the fifth time.

[0066] (4) Five-steamed and five-sunned Polygonatum was placed in a steaming container, steamed f...

Embodiment 2

[0074] Steamed Polygonatum

[0075] (1) Remove impurities and fibrous roots from fresh Rhizoma Polygonatum, wash and dry in the air for 16 hours, place in a 42°C oven and dry for 16 hours to make the moisture content reach 28%, take out and cut into thick slices of 5-8 mm, and then dry in a 45°C oven for 12 hours , so that its moisture content reaches 20%.

[0076] (2) Slice Polygonatum dried in step 1, put it in a steaming container, steam it on high heat for 5 hours, and take it out. Dry it with hot air at 70°C for 12 hours to get steamed and sun-dried Polygonatum.

[0077] (3) Repeat the above step 2 twice. Then, adopt the same operation of step 2 to steam the sealwort with a slow fire; repeat the slow fire steaming and drying for 2 times, and complete 5 times of steaming and drying operations in total to obtain five-steamed and five-sunned sealwort.

[0078] Step 2-3 During the steaming and drying process, control the water content of Polygonatum 18% for the first ste...

Embodiment 3

[0084] Steamed Polygonatum

[0085] (1) Remove impurities and fibrous roots from fresh Rhizoma Polygonatum, wash and dry in the air for 32 hours, then dry in a 36°C oven for 30 hours to make the moisture content reach 24%, take out and cut thick slices of 6-10mm, and then dry in a 38°C oven 32h, make its moisture content reach 17%-19%.

[0086] (2) Slice Polygonatum dried in step 1, put it in a steaming container, steam it on high heat for 7 hours, and take it out. Dry it with hot air at 62°C for 14 hours to get steamed and sun-dried Polygonatum.

[0087] (3) Repeat the above step 2 twice. Then, the Rhizoma Polygonatum was operated similarly to step 2, except that it was steamed at a slow fire for 8 hours, and dried with hot air at 70°C for 10 hours; the steaming at a slow fire was repeated twice in the air. A total of 5 times of steaming and drying operations are completed to obtain five steamed and five dried Polygonatum.

[0088] Step 2-3 During the steaming and dryin...

Abstract

The invention discloses a preparation method of steamed rhizoma polygonati. The preparation method of the steamed rhizoma polygonati comprises the following steps: removing impurities and fibrous roots from fresh rhizoma polygonati, completely washing and airing for 12 to 36 hours, putting into a drying oven with the temperature of 30 to 50 DEG C, and drying for 12 to 36 hours to enable the watercontent to reach 25 to 40 percent; taking outing and cutting into thick sheets of 5 to 10 mm, and drying in a drying oven with the temperature of 40 DEG C for 12 to 36 hours to enable the water content to reach 15 to 24 percent; putting the dried rhizoma polygonati sheets into a steaming container, steaming for 4 to 8 hours and taking out; drying by hot air with the temperature of 55 to 80 DEG C for 10 to 20 hours to enable the water content to reach 12 to 15 percent to obtain one-steamed and one-dried rhizoma polygonati; repeating the above operation for four times to obtain five-steamed five-dried rhizoma polygonati; putting the five-steamed five-dried rhizoma polygonati into the steaming container, steaming for 4 to 8 hours and taking out; and drying by hot air with the temperature of 70 to 80 DEG C to enable the water content to reach 7 percent to obtain six-steamed six-dried rhizoma polygonati, wherein the 5-HMF content of the product is more than or equal to 0.6 mg/g. According to the preparation method provided by the invention, the steaming process is optimally designed and stage-by-stage processing treatment is adopted, so that the rhizoma polygonati product has more excellent quality, has taste and natural component content which are more excellent than those of the prior art, and has remarkable health application advantage.
