| titleOfInvention | Detection method of volatile aldehyde material |
| abstract | This invention is a detection method of volatile aldehyde materials, which can be employed to detect volatile aldehyde material including propanedial, formaldehyde, and acetaldehyde that produced from air, edible oils, or food containing oils during processing, storage, etc. This invention utilizes a nylon foam as a material to react with the volatile aldehyde material after adequate hydrolysis by hydrochloric acid and then to display a coloration phenomenon; and quantification is obtained by comparing the color of the nylon foam with the standard color chip alternatively, the colored nylon foam is dissolved in formal acid and a spectrometer is used to determine absorbance value at the wavelength of 420 nm; aldehyde content in the test sample can be calculated and the aldehyde content in the foam is obtained from the calibration curve. |
