Cleavage of the disulfide bond (R-S-S-R) of DTNB by a sulfite molecule yields the 5-mercaptan- 2-nitrobenzoate molecule
the presence of traces of this protein should be labeled due to the risk posed to the health of allergic individuals
Method: Two-reagent differential at 405 nm
Colorimetric analysis for color determination
Acetic Acid, Y200 / Y400 format Fish & Seafood Cleavage of the disulfide bondKit volume: 225 ml Method: Two reagent differential at 340 nm Limit of linearity: 200 ml l Limit of detection: 0. 1 mg l (ppm) Acetic acid is produced during both alcoholic and malolactic fermentations and helps enhance flavors and aromas. When the wine is aerated or remains in contact with air, acetic acid bacteria can multiply, leading to a problem known as acetic spoilage. The characteristic aroma of this spoilage is due to ethyl acetate.
