Effects on starch and amylolytic enzymes during Lepidium meyenii Walpers root storage

► In this study we identified several isozymes of amylolytic enzymes. ► These enzymes remained stable after harvest, without degrading the starch. ► Total and reducing sugars were similar during the period studied. ► Starch granules did not show enzymatic degradation as observed by SEM. ► The stability of the studied parameters may indicate a latency period after harvest.
