Lipoxidase activity in the samples ground at the lower temperature was similar for the two alkaline soaks and the
pH of the slurry was within the range for optimum activity of soyabean lipoxidase, yet there was a significant difference between the beany flavour scores of these two milks. Despite the milder conditions of the carbonate soaking system which
should have favoured lipoxidase activity more than the conditions in the hydroxide soak, the beany flavour is much less
in the former sample. It seems very likely that there are more significant factors than lipoxidase activity responsible for
this beany flavour.
