The beany flavour of soymilks prepared from beans soaked in varying concentrations of either sodium carbonate or sodium hydroxide was also assessed and the results are shown in Table 2. In the case of preparations soaked in sodium carbonate, the best scores in terms of reduced beany flavour were obtained using concentrations of 0.5 M and 0.4 M in the soaking medium. Since both milks concerned received identical mean scores there was no advantage in using sodium carbonate concentrations higher than 0.4 M under the conditions used. The other milks tested received significantly higher scores in terms of beaniness.
