Problems solved by technology

The existing storage method is boiled and processed, dried, and then stored in woven bags. In actual research, it was found that the water content of curcuma curcuma will gradually increase during storage. When the water content is greater than 15%, according to the provisions of the Chinese Pharmacopoeia It is a substandard product, and the study found that when the water content is greater than 14%, the mold failure rate is greatly increased
In addition, the content of volatile oil in Wen Yujin will also be lost in a large amount during processing and storage.
In the literature "HPLC Research on the Effects of Processing and Storage Processes on the Chemical Composition of Curcuma Curcuma" ("Chinese Experimental Formula Science Impurities" 2011(17): 61~64), through the comparison of the content of active ingredients before and after processing and storage of Curcuma curcuma, during processing, After storage, the active ingredient will be greatly lost

Embodiment 1

[0020] (1) Collect the lateral roots of fresh turmeric, remove fine roots, impurities, and foreign objects, soak in water for 5-10 minutes, scrub off the soil and disease residues attached to the rhizomes, and then rinse with running water for 5-15 minutes;

[0021] (2) Put the rinsed turmeric into the steamer, close the door, heat with small air for 5-10 minutes, then gradually give enough air to make the temperature reach 98-104°C within 20-30 minutes, and then reduce the air supply Keep the temperature at 98-104°C, stop the gas supply after 25-45 minutes, open the door and leave the tank after 25-35 minutes after stopping the gas supply;

[0022] (3) The water content of curcuma curcuma is lower than 14% by far-infrared drying method. Curcuma curcuma is divided into three categories according to the quality: small, medium and large, and they are dried separately. 2 :

Embodiment 3

[0039] (1) Collect the lateral roots of fresh turmeric, remove fine roots, impurities, and foreign objects, soak in water for 5-10 minutes, scrub off the soil and disease residues attached to the rhizomes, and then rinse with running water for 5-15 minutes;

[0040] (2) Put the rinsed turmeric into the steamer, close the door, heat with small air for 5-10 minutes, then gradually give enough air to make the temperature reach 98-104°C within 20-30 minutes, and then reduce the air supply Keep the temperature at 98-104°C, stop the gas supply after 25-45 minutes, open the door and leave the tank after 25-35 minutes after stopping the gas supply;

[0041] (3) Dry in the drying room, the temperature is controlled at 55°C, and the time is 6-8h. Dry until the cross-section is brown and the texture is crisp. Take it out and let it cool. After drying, take a warm curcuma, slice it, the cross-section is brown, and the texture is crisp, take a piece of warm curcuma, crush it into powder, a...

Abstract

The invention relates to a radix curcumae storage method, which comprises the following steps of (1) collecting side roots of fresh radix curcumae; eliminating fine roots, impurities and foreign materials; performing soaking by water for 5 to 10 min; brushing away soil and scar residues attached onto roots and stems; then performing flushing by flowing water for 0.5 to 1.5 min; (2) steaming the flushed radix curcumae for 1 to 2.5 h; (3) processing the radix curcumae by a far infrared drying method so that the water content is lower than 14 percent; (4) coating a glutin layer; then performing drying; (5) packaging the dried radix curcumae by a woven bag; putting the materials under the conditions of the temperature being 10 to 20 DEG C and the humidity being 51 to 53 percent. The method disclosed by the method has the advantages that curcuma zedoary oil and germacrone in the radix curcumae can be well retained; in the storage period, the moisture content increase speed and the reductionspeed of curcuma zedoary oil and germacrone content is slow; the effective storage time of the radix curcumae can be obviously increased.

Description

technical field [0001] The invention relates to a method for storing warm turmeric. Background technique [0002] The stability of traditional Chinese medicine refers to the degree of changes in the chemical, physical and biological properties of traditional Chinese medicine. Stability tests are used to investigate the time-varying laws of traditional Chinese medicines under different environmental conditions, so as to understand and predict the stability trend of medicines, and provide a scientific basis for the determination of production, packaging, storage, and transportation conditions of medicines, and the establishment of expiration dates. [0003] Wen Yujin (Wen Curcuma) is a well-known authentic medicinal material in Wenzhou City. It has anti-inflammatory, bactericidal, and anti-tumor effects, and is currently widely used. The existing storage method is boiled and processed, dried, and then stored in woven bags. In actual research, it was found that the water conte...
