How Vegan Leather is Made From Mangoes | World Wide Waste

For much of this video it looks like they're make fruit leather like I would make at home, an industrial scale fruit roll-up effectively.

I'm not at all sure what the 'several additives' (1:10) that are added to 'turn the mango pulp into a leather-like material', but that's the interesting part that I want to know about.

Because otherwise, yeah, they're just making fruit jerky...and then coating it in (2:00) 'protective glaze'. 

The tiny rectangles of fruit 'leather' are interesting, but the production clearly needs to get stepped up to get some continuous manufacturing going if they want to scale things up.

I do appreciate a good 'turning one man's trach into another man's treasure' story, though, and this looks like it could be a good one.
