Table 7. Extraction efficiency and folic acid content according to extraction time with hot water

Solvent volume (L)	Extraction time (h)	Extraction temperature (°C)	Final quantity (L)	Solid content (°Brix)	Yield (g)	Folic acid content (μg/100g)

Each value represents the mean±SD of three determinations.
Mean with different superscripts (^a-c) are significantly different at p<0.05 by Duncan’s multiple range test.
