Abstract: 【Objective】To determine the effect of various storage methods on the quality of Jerusalem artichoke tubers in order to provide a reference for the advancement of Jerusalem artichoke tubers storage and preservation technologies.【Methods】The tubers of Tumet Jerusalem artichoke were preserved in cellars,warehouses,and the soil once they were harvested and dried. Every 30 days,the dry matter,reducing sugar,and inulin contents were tested,and variations in tuber appearance were noticed,as well as the rotting rate and germination rate were calculated.【Results】Under three storage methods,the quantities of dry matter,reducing sugar,and inulin of Jerusalem artichoke tubers varied significantly(P<0.05). After 120 d of storage,the dry matter content of the cellar,warehouse,and soil storage decreased by 10.40%,16.77%,and 27.83%,whereas the inulin content decreased by 11.60%,4.45%,and 33.47%,respectively. The reducing sugar content decreased by 44.54%,12.82% for cellar and warehouse storage,and increased by 51.13% for the soil storage. The rotting rate and germination rate of Jerusalem artichoke tubers were both zero after cellaring. Some tubers rotted in warehouse storage,with a 7% rotting rate after 120 d. For soil storage,Jerusalem artichoke tubers germination appeared,with a 97% germination rate after 120 d.【Conclusion】Cellaring successfully extended Jerusalem artichoke tubers storage and preservation duration,reduced nutrient consumption,and preserved good appearance and quality. Within 90 d of soil storage,the appearance of Jerusalem artichoke tubers remained unchanged,yet the inulin content reduced dramatically. The Jerusalem artichoke tubers could be stored in the soil,the cellar,or a combination of the two to ensure tuber quality and extend storage period.
