Fruit Texture: How to measure properties of fruit leather, fruit films and fruit peel

Fruit Leather

A fruit leather is made by drying a very thin layer of fruit puree or a mixture of fruit juice concentrate and other ingredients on a flat surface in an oven, desiccators or in direct sunlight, to obtain a product with a chewy texture similar to soft leather. 


Almost any type of fruit is suitable for making fruit leathers. Fruit leather is easy to eat, convenient to pack, and makes an ideal popular snack almost anywhere for a mouth-watering sugar boost. When dried, the product is usually pulled from the surface, rolled and consumed. The control of the drying temperature is very important, as very high temperatures may cause case hardening, hindering the outflow of water. Too thin a layer of purée, on the other hand, can make the product brittle and difficult to be pulled from the surface.
