The inulin level of the finished products was measured using
the method of Sadasivam and Manickam (2007). Samples were
extracted using boiling water and hydrolysed with sucrase and
fructanase. Calculations of inulin were based on fructose measurement. Glucose results of the hydrolysates were not used for inulin
calculations because of possible interference with the measurement of the sucrase and the fructanase hydrolysates, occurring
from glucose released by the hydrolysis of maltose or by partial
hydrolysis of other compounds such as maltodextrins, starch, lactose, or maltitol.
