    Evaluation of Sodium in sweeteners is important in nutritional investigations and for consumers: excessive sodium consumption is one of the major risk factors, responsible for hypertension and cardiovascular diseases. In this study, twelve brands acquired in markets of São Paulo city were analysed by Instrumental Neutron Activation Analyses technique (INAA). The aim was to verify compliance with ANVISA recommendation in relation to sodium level. The results were compared with the amounts recommended and with the tolerable intake limit (< 0.4 g/kg). The sodium concentration in sweeteners samples showed low content for most of the brands. The results shown that for the general population, it is not risk.

    Investigation of elements in sweeteners by NAA analytic technique

    In this study, brands of sweeteners (aspartame and sucralose) marketed in Brazil were investigated by Neutron Activation Analysis (NAA). The measurements were performed using the IEA-R1 nuclear reactor at IPEN - CNEN/SP. The elements Cl and Na were identified in all samples. The Na concentration in sweeteners samples showed low content for most of the brands (0.013 –3.81 g kg-1), while Cl had high concentration variation (0.04 – 11.10 g kg-1). These data provide knowledge regarding nutritional aspect and toxicity derived from sweetener consumption.
