| 目的 为确定最适黄芪的干燥技术，提高其市场前景。方法 本研究采用热风干燥(hot air drying, HAD)、热泵干燥(heat pump drying, HPD)、碳纤维远红外联合热泵干燥技术(carbon fiber far-infrared combined heat pump drying, CFFCHPD)、中短波红外干燥(medium short wave infrared drying, MSWID)、真空脉动干燥(vacuum pulsed drying, VPD)、真空冷冻干燥(freeze drying, FD) 6种方式对黄芪进行干燥试验，比较黄芪的干燥时间、单位能耗、色泽、感官品质以及有效成分，并采用熵权逼近理想排序法(technique for order preference by similarity to an ideal solution, TOPSIS)进行综合评价。结果 结果表明，CFFCHPD干燥黄芪时间最短、能耗最低，分别为(0.15±0.00) h与(3.41±0.03) kw·h·kg-1，且干后样品L*最高，可对保持黄芪原有色泽有积极作用，其他处理组黄芪则发生了不同程度的褐变。VPD组感官评分最高，但与其他处理组差异并不显著。CFFCHPD可赋予黄芪更好的口感，使其鲜味、甜味和丰富度处于较高水平。同时保留黄芪中的甲苷、多糖和毛蕊异黄酮葡萄糖苷等营养成分，获得更优的品质。相关性分析表明黄芪L*与甲苷含量呈负相关，与多糖含量呈正相关，a*与黄芪甲苷含量正相关，可通过色泽间接判断黄芪甲苷与多糖的含量。结论 CFFCHPD综合排序第一，说明CFFCHPD是一种有前途的适用于中药材干燥的联合干燥技术，该研究结果为黄芪高效保质干燥提供一定数据支持。 |

| Objective To determine the most suitable drying technology for Astragalus membranaceus and improve its market prospects. Methods In this study, 6 drying methods including hot air drying (HAD), heat pump drying (HPD), carbon fiber far infrared combined heat pump drying (CFFCHPD), medium short wave infrared drying (MSWID), vacuum pulsating drying (VPD), and vacuum freeze-drying (FD) were conducted to drying experiments. The effect of the drying time, unit energy consumption, color, sensory quality, and effective components of Astragalus membranaceus were evaluated by technique for order preference by similarity to an ideal solution (TOPSIS). Results The results showed that CFFCHPD had the shortest drying time and lowest energy consumption for Astragalus
membranaceus, with (0.15±0.00) h and (3.41±0.03) kw·h·kg-1, respectively. The L* of the dried sample was the highest, which could have a positive effect on maintaining the color of Astragalus membranaceus, while other treatments showed varying degrees of browning. The VPD had the highest sensory score, but there was not significant difference with other treatments. CFFCHPD had a better taste, making its freshness, sweetness, and richness at a high level. At the same time, retaining the nutritional components such as astragalosides, polysaccharides, and calycosin-7-glucoside in Astragalus membranaceus could achieve better quality. Correlation analysis showed that the L* was negatively correlated with the content of astragalosides and positively correlated with the content of polysaccharides. The a* was positively correlated with the content of astragalosides, and the content of astragalosides and polysaccharides can be indirectly judged by color. Conclusion The comprehensive ranking of CFFCHPD ranked first, indicating that CFFCHPD is a promising combined drying technology suitable for drying traditional Chinese medicinal materials. This research result provided certain data support for efficient and high-quality drying of Astragalus membranaceus. |
