Abstract
The invention discloses a detection method of hydroxybenzoic acid propyl ester serving as a food preservative. The detection method adopts a capillary gas chromatography internal standard method. The detection method of the food preservative hydroxybenzoic acid propyl ester has the beneficial effects of being simple, quick, high in sensitivity and good in precision and accuracy; a detection limit can reach 1.0mg/L.
Description
?
Technical field
The present invention relates to the detection method of food preservative nipasol.
Background technology
Propylparaben has another name called propylben, to Para Hydroxy Benzoic Acid propyl ester.Colourless little crystallization or white powder.Be dissolved in hardly cold water.Odorless, astringent taste slightly.The esterification under sulfuric acid exists by P-hydroxybenzoic acid and n-propanol, then through neutralizing, wash, dry, refine as finished product.The main antiseptic as food, cosmetics, feed etc.Share and can improve antiseptic power and dissolubility with ethyl-para-hydroxybenzoate.
Summary of the invention
Object of the present invention is exactly for above-mentioned defect of the prior art, and a kind of detection method of food preservative nipasol is provided.
To achieve these goals, technical scheme provided by the invention is: the detection method of food preservative nipasol is to adopt capillary gas chromatography internal standard method to measure.
Further, the detection method of above-mentioned food preservative nipasol, in described capillary gas chromatography internal mark method determination process, the sample pre-treatments of vapor-phase chromatography is first with hcl acidifying, use again extracted by ether, then with the washing of sodium chloride acid solution, after anhydrous sodium sulfate layer, after volatilizing, water-bath uses again sherwood oil-ether dissolution.
Beneficial effect of the present invention is: the detection method of food preservative nipasol provided by the invention, and method is simple, quick, highly sensitive, has good precision and accuracy, and detection limit can reach 1.0mg/L.
