An inverse three-point bending test method is described for measuring
the strength of the hyphae binding the cotyledons together in soybean
tempe. The force to failure and the work to failure both increased fro
m zero values before hyphal development to maximum values after about
30 h incubation and then declined as the tempe aged and hyphae started
to senesce. The changes in force to failure and work to failure close
ly paralleled changes in the appearance and manual assessments of the
texture of the tempes.
