An edible "second skin" to preserve fruits and vegetables

Founded with a grant from the from the Bill & Melinda Gates Foundation, Apeel Sciences is a California-based startup that's developed a thin "second skin" for fruits and vegetables to preserve them for longer periods. Avocados coated with Apeel will soon hit shelves in Europe. From Technology Review:

The thin coating is made from the pulp, peels, and seeds of other fruit and vegetables. These are turned into powder, which gets mixed with water and then applied to produce by spraying, dipping, or brushing. It's then left to dry. This “second skin” acts like a barrier, slowing down loss of water and exposure to air, the main factors that lead to food spoiling. A lemon that might stay fresh for one month could stay fresh for two or more once it’s been treated with Apeel. And because it’s just made from fruits and other plants, it’s also edible.

This Twinkie is 40 years old and it looks good enough to eat

At Blue Hill, Maine's George Stevens Academy, there lies a Twinkie that was the subject of teacher Roger Bennatti's 1976 science lesson on chemical preservatives and shelf life. Now the immortal snack cake sits in a glass case on the desk of the school's Dean of Students Libby Rosemeier who was a student in the class when the experiment began.

“It’s really funny that we’re this wonderful coastal community in Maine, and we have this school of 325 kids that is a gem and we’re doing great things and kids are going to great colleges, and the thing people know about us is this 40-year-old Twinkie,” Rosemeier told ABC News.

Hostess did not respond to ABC News's request for a comment on the miracle of the everlasting golden spongecake with creamy filling.
