Abstract

The invention provides a method for determining the content of residual sodium n-alkyl benzene sulfonate in beer, which relates to the technical field of beer quality safety detection. The invention discloses a method for determining the content of residual sodium linear alkyl benzene sulfonate in beer. The test method comprises the following materials and reagents: a plurality of parts of bottled beer of different brands, a bottle washing additive, sodium hydroxide, sulfuric acid, chloroform, a sodium n-alkyl benzene sulfonate standard solution, methylene blue, phenolphthalein, ammonium acetate, malachite green, disodium hydrogen phosphate, potassium dihydrogen phosphate, sodium dihydrogen phosphate, diazaphenanthrene, sodium dodecyl benzene sulfonate, methanol, hydroxylamine hydrochloride and an anionic surfactant solution standard substance. The quality safety of the beer can be effectively ensured by determining the content of the residual sodium n-alkyl benzene sulfonate in the beer.

Description

technical field [0001] The invention relates to the technical field of beer quality and safety detection, in particular to a method for determining the content of residual linear alkylbenzene sodium sulfonate in beer. Background technique [0002] Sodium linear alkylbenzene sulfonate, which is commonly used in cleaning agents, brought into beer not only affects the beer foam, but also brings certain hidden dangers to food safety. After the surfactant is adsorbed, it may damage the cell tissue. my country's drinking water quality hygiene requirements also stipulate: anionic synthetic detergent ≤ 0.3mg / L. The benzene core part of the soft sodium alkylbenzene sulfonate in the currently recognized cleaning agent has toxic effects on organisms and aquatic ecosystems after entering the water body. Although there is no unified conclusion about the carcinogenicity and teratogenicity of soft alkylbenzene sulfonate sodium to the human body, it is certain that excessive intake of sof...
