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.

Key words: fermented soy, ammonia nitrogen, examination method
