Description
Technical field
The invention belongs to beer quality assessment technique field, in more detail, relate to the high performance liquid chromatography that is used for measuring ability beer taurine.
Background technology
Is taurine (Taurine) a kind of sulfur-bearing that extensively is present in the humans and animals body? amino acid was just found from the bile of ox and was separated as far back as 1827, and therefore gained the name.Taurine has biologic activity widely as a kind of conditionality essential amino acid in the human body, is the important substance of regulating the body normal physiological function.Studies show that, taurine because of its to the Radical Metabolism in the motion body, Ca
2+Transhipment etc. has good regulating action, thereby shows good anti-sports fatigue effect.At present, release the drink with function of multiple interpolation taurine on the market, as contained sports beer, sports drink of taurine etc.
For these functional beers are carried out strict quality, need set up accurately taurine assay method in the beer.Content of taurine method commonly used has acid base titration, amino acid autoanalyzer method, thin-layered chromatography and high performance liquid chromatography etc. in the detection by quantitative food at present; and the fluorophotometric method that mostly is that detects at beer specially; other method is not applied to beer and detects; because the otherness of the whole bag of tricks and sample is all different at aspects such as sample pre-treatments, analytical procedure and employed reagent.
The fluorophotometric method adopts strong acidic ion resin to isolate taurine in the beer, and carries out fluorescence spectrometry behind o-phthalaldehyde(OPA) (OPA)/2 mercaptoethanol derivatization.Because taurine is sulfonated aminoacid (NH
2-CH
2-CH
2-SO
3H), contain sulfonate radical (SO
3H), least tight with resin-bonded, when at first being eluted through the cationic resin column time, may exist in the sample with more weak other amino acid of resin-bonded and flow out altogether, thereby cause measured value higher.In addition, it is comparatively loaded down with trivial details that resin cation is handled operation, is unfavorable for conventional sense.And owing to there are tens kinds of different types of free amino acids in the beer, easily the detection of taurine produced and disturb, only depend on single fluorophotometric method to be difficult to taurine is separated from other amino acid fully, it is accurately quantitative thereby influence.
