- Abstract
This study aimed at detecting synthesized colorants in sports drink to ensure the health of consumers. Synthesized colorants which are unbeneficial to human body in commonly seen sports drinks were taken as research subjects; detection and analysis method was used. First, the study discussed over the current research status using literature data method, expert interview method, interdisciplinarity method and experimental method. Then the pre-processed sports drink was detected using high pressure liquid chromatography (HPLC) and ultra-high pressure liquid chromatography (UPLC). Finally, the results obtained by detection based on HPLC and UPLC were compared and analyzed. Research results demonstrated that, the value of the linear correlation coefficient R for the detection of the preprocessed sports drink samples using HPLC was between 0.9906 and 0.9995, and the average recycling rate was between 80.5% and 97.1%. The linear correlation coefficient R for the detection of the pre-processed sports drink samples using UPLC was between 0.9909 and 0.9999, and the average recycling rate was between 71.3% and 113.5%. Compared to HPLC, UPLC was more sensitive. UPLC makes up the blank of multi-group detection of colorants and provides a technical support for the detection of colorants in sports drink.
