studies have specifically reported an association of minerals,
such as calcium, manganese, and boron with natto quality.
However, it is important to examine if there is a correlation between
these minerals, other soybean chemical quality traits, and
natto quality. For example, calcium performs structural roles in
the cell walls and membranes manganese
is important to photosynthetic oxygen evolution in chloroplasts
within most plants and boron
maintains the integrity of cell walls. However, there is no information
regarding the effect of these minerals on soyfood quality.
