Fruit juices are not as easy to dry as protein or starch based foods. The high sugar content. consisting primarily of the reducing sugar. glucose and fructose, presents a problem. At low moisture levels the products are quite hygroscopic readily picking up moisture from the air to become sticky and difficulty to manipulate. Dried fruit products, especially juices must be protected from the atmosphere during and after drying. An ideal drying n is maintained around 10 percent relative humidity. The dry product is then rapidly packed into a hermetically sealed moisture barrier material, either a bulk container or final package.
