Application of modern instrumental analysis methods in sugar inspection

The sugar analysis and detection runs through the whole production process of sugar industry， testing the raw materials to ensure that the quality of product meets the production requirements. The inspection of semi finished products in the production process can provide basis for the improvement of production process，and the inspection of finished products can ensure the quality of products，and it can not be used in different process flow. Traditional sugar analysis technology has many shortcomings，such as long analysis time，no simultaneous analysis of multiple items，lack of accuracy and precision. With the promulgation and implementation of the national standard for GB13104-2014 sugar safety，the quality and safety of sugar have been paid more and more attention. Through the study of molecular spectroscopy（ UV visible spectroscopy，near infrared spectroscopy），atomic spectroscopy （atomic absorption spectrometry，atomic emission spectrometry） and chromatography（ gas chromatography，liquid chromatography） ，the application of modern instrument analysis technologies in the field of sugar analysis was summarized，such as the analysis of components in sugar，pollutants and additives，to ensure the efficient operation of sugar production process and the safety of product quality，and to provide a scientific basis for the renewal of inspection methods and standards.
