The current national standard employs the phenol-sulfuric acid method for quantifying the curdlan content.However,due to inadequate dispersion of some curdlan particles in the solvent caused by agglomeration during dissolution in a 0.1mol/L sodium hydroxide solution,the results of content detection were found to be unstable.The samples were treated by magnetic stirring,homogenizer dispersion and ethanol dispersion.It was found that:The ethanol effectively disperses the curdlan sample in the sodium hydroxide solution,preventing it from agglomerating.The ethanol method effectively and efficiently addresses the pain point in determining the content of curdlan,offering valuable insights for enhancing the detection methodology.
