The dietary exposure to low-calorie sweeteners (LCS) was estimated in a sample of pregnant Brazilian women. Consumption data were obtained with a 24-h Dietary Recall interview. Because of the uncertainty in assessing foods with LCS, they were classified into three scenarios to ensure inclusion of the 15 LCS allowed for use in Brazil: ranging from a less to a more conservative scenario. The concentration of LCS was estimated using the amount declared on the label or the maximum permitted levels and anal. determination data for table-top sweeteners. The frequency of consumption was higher for acesulfame-K, aspartame, and cyclamate. The food groups contributing the most to the consumption of LCS were non-alc. beverages, table-top sweeteners, confectionary and desserts. The level of dietary exposure to LCS was within the safety limit. However, continued efforts to monitor their dietary exposure are necessary given the limitations highlighted in this study. In the experiment, the researchers used many compounds, for example, (2R,3S)-rel-Butane-1,2,3,4-tetraol (cas: 149-32-6Safety of (2R,3S)-rel-Butane-1,2,3,4-tetraol).
(2R,3S)-rel-Butane-1,2,3,4-tetraol (cas: 149-32-6) belongs to alcohols. Under appropriate conditions, inorganic acids also react with alcohols to form esters. To form these esters, a wide variety of specialized reagents and conditions can be used. Alcohols may be oxidized to give ketones, aldehydes, and carboxylic acids. These functional groups are useful for further reactions. Oxidation of organic compounds generally increases the number of bonds from carbon to oxygen (or another electronegative element, such as a halogen), and it may decrease the number of bonds to hydrogen.Safety of (2R,3S)-rel-Butane-1,2,3,4-tetraol
