| titleOfInvention | Microdetection of sulfurous acid in food and brew |
| abstract | PURPOSE:To enable quantitative determination of a trace amt. of sulfurous acid with high sensitivity by adding specific maleimide to the sample liquid obtd. from food and brew and bringing the same into reaction with the sulfurous acid in the sample. CONSTITUTION:The N-(9-acridinyl)maleimide (NAM) having the constitutional formula shown in the figure is dissolved in a solvent such as, for exaple, acetone (more preferably at about 10-100 times mole of SO2 in the sample). Such soln. and the sample liquid are mixed at 7-10pH, more preferably at 8.8pH in a buffer soln. such as Na2CO3-H3BO3.KCl buffer soln. Then SO2-NAM is formed and the soln. forms the fluorescence of a dark bluish color (435nm max. fluorescent wavelength, 360nm max. excitation wavelength). The exact quantitative determination of the amt. of SO2 in the sample liquid is thus made possible by measuring said fluorescence with a fluorescence spectrophotometer. The above-mentioned method is particularly effective for quantitative determination of the sulfurous acid in drinks and the quantitative determination of the sulfurous acid formed by fermentation reaction in the stage of brewing beer, etc. |
