The satisfactory results for ponceau 4R, sunset yellow and amaranth were all 93.55%.
胭脂红、日落黄和苋菜红的检测结果满意百分率均为93.55%。
Sunset yellow and ponceau 4r were simultaneously determined by dual wavelength equalizing-account method.
采用双波长补偿计算法同时测定饮料中的食用合成色素日落黄与胭脂红。
Based on this phenomenon, a new method for the determination of proteins by the resonance Rayleigh light-scattering technique (RRLS) using ponceau 2r as probe agent has been developed.
