Problems solved by technology

[0007] The technical problem to be solved by the present invention is to overcome the method that most of the preparation methods of tangerine peel medicinal materials in the prior art adopt the method of coal fire drying so that the residual sulfur dioxide in the tangerine peel is high, the content of volatile oil is low, and after a certain shelf life period, the volatile oil components are easy to dry. Volatilizes and rapidly reduces, seriously affects the medical value of tangerine peel medicinal materials, and reduces the defect of clinical curative effect, provides a kind of preparation method of tangerine peel

Embodiment 1

[0041] Blanch the fresh orange peel at 90°C for 30 seconds, peel off the skin to remove mildew, black skin, and sundries; steam dry at 65°C for 6.5 hours to obtain tangerine peel.

[0042] Volatile oil content is detected by "Chinese Pharmacopoeia" 2010 edition tangerine peel item and appendix XD volatile oil determination method, and sulfur dioxide content is detected by appendix IXU sulfur dioxide residual determination method. The test results are as follows: the content of volatile oil in tangerine peel is 2.10mL / 50g, and the residual amount of sulfur dioxide is <20mg / kg.

Embodiment 2

[0044] The fresh oranges are scalded at 90°C for 30 seconds, and the peels are manually peeled to remove mildew, black skin, sundries, etc. The fresh skin is dried with water steam, at 85°C for 1 hour, then at 75°C for 1 hour, and finally at 65°C for 2 hours; completely dry to obtain tangerine peel.

[0045] According to " Chinese Pharmacopoeia " 2010 editions appendix XD and the method for recording in IXU detect the content of volatile oil and sulfur dioxide in orange peel, test result is as follows: the content of volatile oil in orange peel is 2.13mL / 50g, sulfur dioxide residual amount<20mg / kg.

Embodiment 3

[0047] Blanch the fresh oranges at 90°C for 30 seconds, peel them manually to remove moldy skin, black skin, and sundries; dry the fresh peels with water steam, and bake them at 90°C, 80°C, 70°C and 65°C in sequence. Dry for 1 hour to get tangerine peel.

[0048] Press " Chinese Pharmacopoeia " 2010 editions appendix XD and the method for recording in IXU to detect the content of volatile oil and sulfur dioxide in dried orange peel, test result is as follows: the content 2.11mL / 50g of volatile oil in dried orange peel, residual amount of sulfur dioxide<20mg / kg.

Abstract

The invention discloses a preparation method for a dried orange peel. The preparation method comprises the steps of boiling an orange for 30 to 35 seconds at the temperature of 90 to 95 DEG C, and peeling the orange to obtain an orange peel; performing steam drying on the orange peel. According to the steam drying method, when the steam drying is performed for one time, the drying temperature is 65 to 70 DEG C, and the drying time is 6 to 6.5 hours; when the steam drying is performed for two to five times, drying temperature of the first time is 85 to 90 DEG C, drying temperature of the subsequent times is decreased progressively, drying temperature of the last time is 65 DEG C, and drying time of each time is 1 to 2 hours. The dried orange peel prepared through the method does not contain sulfur dioxide, is high in volatile oil content, is unlikely to be volatilized, can be in accordance with a pharmacopeia standard in the next year under the cool storage condition, and has an important clinical pharmaceutical value.

Description

technical field [0001] The invention relates to a preparation method of tangerine peel. Background technique [0002] Tangerine peel is the dried and mature peel of the rue plant orange tree (Gitrus rdticulatr Blanco). Its common names are Guangpi, Guangchenpi, Xinhuipi and Tangerine peel. commonly used Chinese herbal medicines.
