Development and Application of the New Integrated Equipment and Process of the Nine-Steam-Nine-Bask Method in the Processing of Polygonatum cyrtonema

Abstract

As a traditional processing method, the Nine-Steam-Nine-Bask method has been widely used in the special processing of Chinese medicinal materials. With the highly integrated design and innovation of infiltrating equipment, steaming equipment, drying equipment, and other equipment, a new type of integrated equipment for the Nine-Steam-Nine-Bask method was finally developed and successfully applied in Polygonatum cyrtonema processing. Moreover, seven new processes were explored. The longer the steaming time was, the more steaming and drying cycles, the lower the product recovery rate and the higher the energy consumption. The higher the steaming pressure was, the lower the product recovery rate, the higher the energy consumption and the shorter the drying time. The longer the drying time was, the lower the product recovery rate and polysaccharide content, and the higher the energy consumption. The best new process was XGY1, which had the highest overall score. The steaming process was the most time-consuming and energy-intensive production process, followed by the drying process. The obtained results can provide knowledgeable guidance for the further optimization of the integrated equipment of the Nine-Steam-Nine-Bask method and the development and application of technology for processing characteristic Chinese medicinal materials.

Quality Evaluation of Polygonatum cyrtonema Hua Based on UPLC-Q-Exactive Orbitrap MS and Electronic Sensory Techniques with Different Numbers of Steaming Cycles

“…To sum up, the processing times of the traditional "Nine Steaming Nine Sun-drying" method are longer, affecting the quality of industrial products and production costs. Reducing the number of steaming cycles in the PCH process can effectively save on economic and time costs, ultimately enhancing industry efficiency [81]. Therefore, based on sensory quality traits, chemical composition, and multi-component index content, the preliminary inference suggests that five cycles of steaming and sun-drying is optimal.…”

Historical evolution and processing mechanism of ‘nine steaming and nine drying’ of traditional Chinese medicine preparation

“…Though nine steaming and nine drying is recorded in many ancient books of Chinese medicine, the ancient ‘nine’ has many meanings, some indicate the exact number, some indicate the repeated behavior, and some refer to a long time because of the sound with ‘long’ (Liu J et al. 2022 ). Also, it may be related to ancient Chinese understanding of nine, as Seeking Truth from the Original Grass says, ‘…steamed and dried nine times (numbers ends with nine)’ (Huang GX 1997 ).…”

Modulatory effects of fermented Polygonatum cyrtonema Hua on immune homeostasis and gut integrity in a dextran-sulfate-sodium-induced colitis model

“…15 However, intensive steaming is an energy-intensive and time-consuming process. 16 Moreover, intensive steam–sun drying leads to the biotransformation of phytochemical constituents and the release of toxic byproducts of the Maillard reaction, raising a potent health concern. 17 Therefore, novel eco-friendly food processing approaches are warranted for preparing P. cyrtonema Hua-based food products.…”
