Sucrose octaacetate.

Sucrose octaacetate (SOA) is a United States National Formulary (NF) monograph compendial material (U.S. Pharmacopeia, 2008), and, as shown in Fig. 1, has eight acetate groups attached to a sucrose moiety. It is a natural product that has been extracted from the seeds of Annona cornifolia (Lima et al., 2011). It is nontoxic (Sigma-Aldrich, 2016) and has a number of uses based on its bitter taste. For example, sugar is rendered too bitter is eat at a concentration of 0.06% (w/w) SOA (Mann et al., 1992). SOA can form 255 different possible isomers and degradation products, all of which have a very low molar absorptivity. Its ultraviolet molar absorptivity at 210nm has been reported to be 439 absorption units/cm/M in water and 442 absorption units/cm/M in 30:70 acetonitrile-water.
