Fresh processing method of radix paeoniae alba

Abstract

The invention discloses a fresh processing method of radix paeoniae alba. The fresh processing method comprises the following steps: soaking cleaned radix paeoniae alba with a citric acid aqueous solution; peeling the radix paeoniae alba by using a rotating drum to achieve an effect of primary color protection; then steaming and slicing the peeled radix paeoniae alba and performing chemical colorprotection treatment on the sliced radix paeoniae alba to fulfill an aim of effectively preventing browning and keep original color quality of the radix paeoniae alba; then putting the sliced radix paeoniae alba under the high-voltage electric field, and performing periodic drying treatment; therefore, the drying speed of the sliced radix paeoniae alba can be effectively accelerated, the drying time is effectively shortened, effective ingredients such as paeoniflorin are reserved to a maximum extent, and the form of the sliced radix paeoniae alba after drying is in good condition; meanwhile, enzyme is inactivated or passivated, so that a sterilization effect is achieved, and the storage time of the radix paeoniae alba is prolonged.

Description

technical field [0001] The invention belongs to the technical field of processing traditional Chinese medicinal materials, and in particular relates to a fresh processing method of Radix Paeoniae Alba. Background technique [0002] At present, the processing technology of Radix Paeoniae Alba is mostly peeled after harvest, boiled, then dried naturally into Radix Paeoniae Alba, softened and cut into Radix Paeoniae Alba before use, the processing is labor-intensive and time-consuming, and because paeoniflorin is easily soluble In water, boiling and softening can easily cause the loss of active ingredients such as paeoniflorin. In addition, in the process of natural drying and softening, it is easy to appear sticky and mildew. Later, it is smoked with sulfur. Good anti-rot effect, can promote its drying, has bactericidal and bleaching effects, and increases the color and beauty of the finished product, but the sulfur fumigation method also has many disadvantages, such as direct...

[0002] At present, the processing technology of Radix Paeoniae Alba is mostly peeled after harvest, boiled, then dried naturally into Radix Paeoniae Alba, softened and cut into Radix Paeoniae Alba before use, the processing is labor-intensive and time-consuming, and because paeoniflorin is easily soluble In water, boiling and softening can easily cause the loss of active ingredients such as paeoniflorin. In addition, in the process of natural drying and softening, it is easy to appear sticky and mildew. Later, it is smoked with sulfur. Good anti-rot effect, can promote its drying, has bactericidal and bleaching effects, and increases the color and beauty of the finished product, but the sulfur fumigation method also has many disadvantages, such as direct harm to the human body: including the toxicity of sulfur and heavy metals; It also has an impact: it can destroy the active ingredients contained in the medicine, and the content of the active ingredients is significantly reduced after sulfur fumigation; in addition, after fumigation, sulfur dioxide gas diffuses into the air, which is very serious for environmental pollution.

Moreover, during the storage of Radix Paeoniae Alba, with the prolongation of time, it is prone to mildew, and the content of paeoniflorin is in a downward trend, which will also reduce the efficacy of Radix Paeoniae Alba.
