evidence: According to Apeel’s website, the purpose of using Apeel on produce is to reduce food waste by slowing down spoilage. Apeel is a coating sprayed onto produce after being picked. They claim it’s made of purified mono and diglycerides derived from sustainably sourced, non-GMO plant oils, with citric acid from organic produce. Note that Apeel can only be used on organic produce in the US but not in the EU or UK. [...] According to Apeel, their coating is completely safe: "The safety of mono- and diglycerides have a long history of safe consumption and are a commonly used food ingredient." While Apeel claims to be completely safe, non-toxic, and even tests for heavy metals, it’s important to note that according to Apeel’s GRAS (Generally Recognized as Safe) Notice by the FDA, states its edible coatings may have residues including ethyl acetate, heptane, palladium, arsenic, lead, cadmium, and mercury. However, Apeel can say their product is "safe" as the FDA concluded that the residues of these substances were below their required limits.
