The application to the determination of total sulfite in 40 kinds of f
oods by the microbial biosensor method was examined. The recovery of a
dded sulfite from 40 kinds of foods was more than 90%. The total sulfi
te values determined by the microbial biosensor method were coincided
with those obtained by the modified Rankine's titration method. These
results indicated that the microbial biosensor method was applicable t
o the determination of sulfite in various foods.
