Sucralose and The Environment

Your Questions AnsweredAbout the Environment

Have the environmental properties of sucralose been reviewed by regulatory authorities?

Yes.  Environmental data was reviewed as part of the United Kingdom (UK) Sucralose Food Additive Petition in the 1990’s.  In addition, the US FDA reviewed the potential for environmental impacts in the late 1990’s.  Regulatory authorities agreed that sucralose posed no risk to the environment (FDA 1999).

Is sucralose measured in the environment; and is the science around sucralose in the environment continually being reviewed and assessed?

Sucralose has been detected in the environment, as is most of what people consume and excrete as part of daily life, with most of the reports stemming from sucralose in various water bodies, such as lakes, rivers and streams.  The concentrations of sucralose reported today are similar to those predicted in the 1990’s prior to the market introduction of sucralose. New reports and publications related to sucralose in the environment are routinely monitored.  It is important to review these reports to ensure that sucralose is safe for the environment.  In 2012, a re-review of all sucralose environmental data was published by Norwegian and American scientists in the journal Science of the Total Environment (Tollefsen et al., 2012). Based on the original data from the UK Food Additive Petition and newer published data, the scientists concluded that sucralose poses no risk to the environment.

Does sucralose accumulate in the tissues of plants and wildlife?

Published studies by the IVL Swedish Environmental Research Institute, Swedish Environmental Research Institute, and the Norwegian Institute for Water Research determined that sucralose does not bioaccumulate in aquatic plants, invertebrates, and fish (Brorström-Lundén, E et al. 2008 Part I and Brorström-Lundén, E et al. 2008 Part II). A series of short and long term ecotoxicological studies with plants and animals have been conducted with sucralose. These studies follow internationally validated and accepted methodologies.  No adverse effects (e.g. survival, growth and reproduction) were observed in these studies. In fact, the concentrations of sucralose utilized in these studies are higher than those detected in the environment

Is sucralose toxic to plants and wildlife?

No.  A series of short and long term ecotoxicological studies with plants and animals have been conducted with sucralose.  These studies follow internationally validated and accepted methodologies.  No adverse effects (e.g. survival, growth and reproduction) were observed in these studies.  In fact, the concentrations of sucralose utilized in these studies are higher than those detected in the environment.
