In order to establish a kind of fast, simple, accurate and practical analysis method for determining the sucrose content in foods, sucrose content in sugarcane and commercial white sugar was determined by polarimetry using ultrasonic-assisted accelerated reaction. The results showed that sucrose content in sugarcane juice was 11.97 g/100 ml, with RSD of 0.61%(n=7). The sucrose content in white granulated sugar was 84.53 g/100 ml, with RSD of 0.85%(n=7). This method is visual, rapid, simple and efficient.
