建立了非发酵豆制品中合成着色剂测得的高效液相色谱法。用无水乙醇-氨水(2ml浓氨水稀释至100m1)-水(70:20:10)提取合成着色剂,采用AgilentEclipseXDB—C18(4.6ram×150mm,5μm);流动相:甲醇-0.02m0儿乙酸铵,梯度洗脱,流速为1.0ml/min,柱温:35℃,检测波长:254nm。在此色谱条件下进行检测,结果表明,两种合成着色剂,方法回收率均为90%以上,方法最低检出限均为0.02mg/kg。该方法可有效检测非发酵豆制品中合成着色剂含量。
建立瞭非髮酵豆製品中閤成著色劑測得的高效液相色譜法。用無水乙醇-氨水(2ml濃氨水稀釋至100m1)-水(70:20:10)提取閤成著色劑,採用AgilentEclipseXDB—C18(4.6ram×150mm,5μm);流動相:甲醇-0.02m0兒乙痠銨,梯度洗脫,流速為1.0ml/min,柱溫:35℃,檢測波長:254nm。在此色譜條件下進行檢測,結果錶明,兩種閤成著色劑,方法迴收率均為90%以上,方法最低檢齣限均為0.02mg/kg。該方法可有效檢測非髮酵豆製品中閤成著色劑含量。
건립료비발효두제품중합성착색제측득적고효액상색보법。용무수을순-안수(2ml농안수희석지100m1)-수(70:20:10)제취합성착색제,채용AgilentEclipseXDB—C18(4.6ram×150mm,5μm);류동상:갑순-0.02m0인을산안,제도세탈,류속위1.0ml/min,주온:35℃,검측파장:254nm。재차색보조건하진행검측,결과표명,량충합성착색제,방법회수솔균위90%이상,방법최저검출한균위0.02mg/kg。해방법가유효검측비발효두제품중합성착색제함량。
Establish a method to determination of synthetic colorants in non-fermentedbean products by HPLC. extraction of synthetic colorants with Anhydrous ethanol - ammonia.Use Agilent Eclipse XDB-C18 (4.6mm ×150mm, 5 μ m ) ; Mobile phase: methanol-0.02mol / L ammonium acetate; Gradient elution with a flow rate of 1.0ml/min, column temperature: 35℃, detection wavelength: 254nm. Be detected under this chromatographic conditions, results show that the method recoveries were 90%, method minimum detection limits were 0.02mg/kg. This method can effectively detect the content of synthetic colorants in non-fermented bean products.
