Thank Nienke for your reply. I guess fruits pulp are an excellent binder when they are smashed. Cellulose maybe. How would you compare mangoes’ leather to bacterial cellulose? Heavier, stronger? Does yeast feed on the sugar in the fruit? I read they use PU & a polyester base. Make-Grow lab said they use no plastics may be to produce the skin, but like fruit leather when the skin is used to make products PU and polyester must be added.
In Egypt, we have sometimes an excess in production other times tomatoes are very rare and very expensive. Depending on the weather conditions. Excellent idea after trying to dry tomatoes for eating it later. I am looking forward to seeing how would your product look like. Inspiring!
