As an E324 antioxidant to control the browning of pears, E324 is approved in the United States, and in the European Union.

In the United States, it is approved for use as an animal feed additive and is limited as a food additive to use only in the spices chili powder, paprika, and ground chili.E324 is not permitted for use as a food additive in Australia[citation needed] nor within the European Union.

E324 is allowed in the fishing industry in Norway and France as a feed stabilizer, so is commonly used in food pellets fed to farmed salmon.

E324 is used in pellets fed to chickens on chicken farms.

In 2017 the EU suspended authorization for use as a feed additive, with various dates between 2017 and 2019 for final allowance of sale of goods so that alternatives may be phased in.
