Abstract: The sulfur is an essential element of the body,and the sulfur compounds in animal and plant foods are the main source of sulfur in the body. Therefore,accurate measurement of the total sulfur content in food is the key to evaluate the dietary sulfur intake of different populations. However,the commonly used methods,such as ion chromatography,high-resolution continuous light source atomic absorption spectrometry and inductively coupled plasma mass spectrometry,have their own advantages in sample application,determination principle,sample pretreatment method and matrix interference.This paper comprehensively analyzes the sensitivity,accuracy,applicability and scope of sample application of different sulfur determination methods in order to provide an optimal reference for establishing an ideal and practical method for the determination of total sulfur in animal and plant food to accurately measure the sulfur intake of people and for sulfur nutrition intervention of different occupational groups.

Key words: Total sulfur, Food, Ion chromatography, Inductively coupled plasma mass spectrometry, High resolution continuous source atomic absorption spectrometry
