Comparison of the Microbial Biosensor Method with the Modified Rankine's Method for Determination of Sulfite in Fresh and Dried Vegetables Including Sulfur Compounds

The application to the determination of sulfite in dried vegetables by the microbial biosensor method was examined. The recovery of added sulfite from 4 samples was more than 86%. The total sulfite was not detected by the microbial biosensor method. On the other hand, the modified Rankine's tit...

Zusammenfassung:The application to the determination of sulfite in dried vegetables by the microbial biosensor method was examined. The recovery of added sulfite from 4 samples was more than 86%. The total sulfite was not detected by the microbial biosensor method. On the other hand, the modified Rankine's titration method was difficult to apply to determine sulfite in dried vegetables because of influence by sulfur compounds in dried vegetables. These results indicated that the microbial biosensor method was applicable to the determination of sulfite in dried vegetables including sulfur compounds.
