Abstract

: Inulin is a polysaccharide rich in dietary fiber and is widely used in functional foods due to its health-promoting properties. It has an important place in the current market, with the increasing demand for innovative formulations in the food and pharmaceutical industries. Jerusalem artichoke ( Helianthus tuberosus ) tubers are an important source of inulin, and this polysaccharide can be extracted for industrial use. Green solvent extraction systems have been used in recent years due to advantages such as non-toxic and environmentally friendly properties, as well as reducing solvent usage compared to traditional methods. In this study, inulin powder production from Jerusalem artichoke was carried out by conventional (C), hydrotropic solvent (HS) and deep eutectic solvent (DES) extraction methods, according to the experimental plans created by the response surface methodology (RSM). The effects of independent parameters such as temperature, time and solvent ratio on inulin yield were investigated. Also, the combined effects of extraction parameters were examined using three-dimensional response surface plots. The optimum process conditions were determined as 79 ◦ C process temperature, 36 min process time, 78 mL/g solvent ratio for C; 68 ◦ C, 53 min, 59 mL/g for HS; and 79 ◦ C, 51 min, 61 mL/g for DES. Among the extraction methods, HS provided the highest inulin yield (88.9%), followed by C (81.9%) and DES (81.5%). Inulin extracts produced under optimum conditions were purified by an ultrafiltration system and freeze-dried with a lyophilization process to obtain inulin powder. Viscosity and solubility values were also determined for each inulin powder sample. The solubility of inulin powders prepared by C, HS and DES extraction techniques were 91.5, 82.6 and 84.1%, respectively. The viscosity values of inulin powders within aqueous solutions (5 g/100 mL) were found to be 28.2, 17.1 and 8.1 mPa · s for C, HS and DES, respectively. The results depict that the highest inulin yield could be obtained by the hydrotropic solvent extraction system, but the solubility and viscosity values were found to be the highest using the conventional extraction technique.

从菊芋中生产高产菊粉的绿色提取技术的潜力

:菊粉是一种富含膳食纤维的多糖，因其具有促进健康的特性而被广泛应用于功能性食品中。随着食品和制药行业对创新配方的需求不断增加，菊粉在当前市场上占有重要地位。菊芋（Helianthus tuberosus）块茎是菊粉的重要来源，这种多糖可提取用于工业用途。与传统方法相比，绿色溶剂萃取系统具有无毒、环保以及减少溶剂用量等优点，近年来已得到广泛应用。本研究根据响应面方法学（RSM）制定的实验方案，采用传统（C）、氢丙溶剂（HS）和深共晶溶剂（DES）萃取法从菊芋中生产菊粉。研究了温度、时间和溶剂比例等独立参数对菊粉产量的影响。此外，还利用三维响应面图研究了提取参数的综合效应。确定最佳工艺条件为：C 的工艺温度为 79 ◦ C，工艺时间为 36 分钟，溶剂比率为 78 毫升/克；HS 的工艺温度为 68 ◦ C，工艺时间为 53 分钟，溶剂比率为 59 毫升/克；DES 的工艺温度为 79 ◦ C，工艺时间为 51 分钟，溶剂比率为 61 毫升/克。在各种提取方法中，HS 的菊粉产量最高（88.9%），其次是 C（81.9%）和 DES（81.5%）。在最佳条件下提取的菊粉经超滤系统纯化后，用冻干工艺冷冻干燥，得到菊粉粉末。同时还测定了每个菊粉样品的粘度和溶解度值。采用 C、HS 和 DES 提取技术制备的菊粉的溶解度分别为 91.5%、82.6% 和 84.1%。菊粉在水溶液（5 克/100 毫升）中的粘度值分别为 28.2、17.1 和 8.1 毫帕-秒（C、HS 和 DES）。结果表明，水溶剂萃取系统的菊粉产量最高，但传统萃取技术的溶解度和粘度值最高。
