Sugars
In fresh okara, the free sugars present were glucose and fructose, at
1.42 g/100 g dry matter (Fig. 1C) and 1.37 g/100 g dry matter (data
not shown) respectively. However, fructose was not consumed
throughout fermentation (data not shown) as Y. lipolytica hexokinase
has a low affinity for fructose
