If you thought fruit was safe for vegans, think again. Non-vegan bananas could be making an appearance at your grocery store. During the 244th National Meeting & Exposition of the American Chemical Society, scientists discussed a new spray that could prevent bananas from becoming over-ripe. However, this spray is made from “hydrogel”, which contains chitosan, a substance derived from shrimp and crab shells.

There’s a disturbing rumor making the rounds that the versatile banana, a food most parents count on as the perfect go-to fruit for their tots, may no longer be vegan-friendly. Scientists at the 244th National Meeting & Exposition of the American Chemical Society recently had a nice big discussion about how a cool new spray-coating may save consumers from bananas becoming over-ripe before their time. The solution, spray bananas with a chemical coating of “hydrogel,” a superabsorbent material made from chitosan, which by the way, is a substance derived from shrimp and crab shells. Xihong Li, Ph.D., the main scientist presenting the idea, says that “Chitosan is attracting considerable attention in efforts to keep fruits and vegetables fresher longer due to its action in killing bacteria that cause produce to rot.” Science Daily calls it, “Good news for banana lovers” but we call it a big fat problem for vegans.
