Abstract

This paper is devoted to determine the concentration of two types of food additives using continuous injection technique supported by a new software designed by the authors. This methodology was developed to determine the tartrazine and sodium benzoate in some locally traded juices and the results obtained were compared with those obtained using traditional methods in the literature. The data is then received by a signal detector and a developed software spectrometer where a spectral scan was used to obtain the maximum wavelength for the two substances, a calibration curve was constructed and measurements obtained to find the actual concentrations of the two substances in the selected juices. It was found that the detection limit and the quantitative limit are 0.229, 0.694 and 0.221, 0.666 ppm for tartrazine and sodium benzoate respectively. This method is simple, fast, accurate, economical and versatile, which makes it a preferred routine method.

连续流动注射法测定某些地方果汁中食品添加剂酒黄石和苯甲酸钠

本文采用自行设计的软件，采用连续注射技术测定两种食品添加剂的浓度。本方法用于测定一些当地销售的果汁中的酒石黄和苯甲酸钠，并与文献中采用传统方法测定的结果进行了比较。然后，信号检测器和开发的软件光谱仪接收数据，其中光谱扫描用于获得两种物质的最大波长，构建校准曲线并获得测量结果，以确定所选果汁中两种物质的实际浓度。酒石黄和苯甲酸钠的检出限和定量限分别为0.229、0.694和0.221、0.666 ppm。该方法简便、快速、准确、经济、用途广泛，是常用的常规方法。
