Why are Topinambur tubers generally considered less suitable for long-term storage in a cool, dark place compared to regular potatoes?
Answer
Because their primary stored energy component is inulin rather than starch.
The structural composition of the tuber dictates its shelf life. Potatoes are primarily composed of starch, which allows them to remain viable and relatively stable when stored correctly in cool, dark conditions for extended periods. In contrast, the energy storage mechanism for Topinambur centers on inulin. Due to this chemical difference, the tubers do not maintain their quality over time as effectively as potatoes do, meaning they are best used relatively soon after they have been acquired or harvested to ensure optimal texture and nutritional value.
