The article presents methods for the physico-chemical analysis of the composition of topinambur tubers. In this study, combined drying methods, including sublimation (freeze-drying) and convective techniques, were used. Through the comprehensive processing of tuber crops, particularly topinambur (Jerusalem artichoke), waste-free products can be obtained. These products are effectively used as a primary source of raw materials for the food, pharmaceutical, livestock, and agricultural industries.
Improvement of the technology for the complex processing of tuber crops, as well as the development of parameters for convective and sublimation drying processes of the primary and secondary mass, ensures high quality and organoleptic characteristics of the dried product. During the drying process, treatment with ascorbic and citric acids increases the drying rate and allows optimization of the critical moisture content.
