Abstract:Ejiao exhibits identical spectral characteristics with those of reference gelatin in Murphy’s UV spectrophotometryand color-yielding reactions performed according to Gornall’s biuret and Lowry’s Folin phenol procedures respectively.Results of protein assays of Ejiao measured by above-mentioned photometric methods were in gcod appro-ximation toeach other using gelatin as standard and comparable with that of Kjeldahl nitrogen determination.
