英文摘要:

      Objective To compare the detection effect of three kinds of casein ELISA kits on the market. Methods The recovery, precision and specificity of three brands of ELISA kits were compared by adding positive ingredients, such as skim milk powder and casein. Results ELISA kits could detect casein content in a variety of foods. The recovery, precision and other performance could meet the relevant detection limit requirements. Conclusion The method is easy to operate and does not require any complex equipment. It is applicable to rapid screening for a large number of samples and a variety of primary laboratory food quality monitoring.
