摘要: 分别用ZBX66014-87标准、GB/T5009.39-1996标准对同一酱油样品进行分析测定,并用茚三酮比色法进行对照。结果显示:GB/T5009.39-1996标准测定氨基氮含量偏低,ZBX66014-87标准测定氨基氮含量偏高,但ZBX66014-87法扣除半微量凯氏定氮法所测铵盐氮含量后,结果与茚三酮比色法所测值相当。

Abstract: Use the right same sauce sample of standards of standards, GB/ T5009.39-1996 s of ZBX66014-87 the proceeding the analysis the measurement respectively, And Comparative used Ninhydrin colorimetric method. Result manifestation: GB/ T5009.39-1996 standard measurement ammonia the nitrogen contain to measure low, ZBX66014-87 standard measurement am- monia the nitrogen contain the deal to is higher. But ZBX66014-87 standard measurement ammonia the nitrogen contain deduct the content of NH4 -N with Semi-micrometheel of Kai,s Fixed Nitrogen, result is equal and Comparative with Ninhydrin colorimetric + method.
