But once they're picked, that grower had maybe about seven days before their organic limes would start to dry out and the skin would start to change color, and that was even with refrigeration.

So we took a test batch of material that we made using leftover tomato peels, since those are rich in these fatty acids and glycerides.

We dipped those limes in a bowl of these ingredients in water and set them aside to dry.
