n, which inhibits the enzymatic browning. Normally, apples of size bigger than 6.3 cm (2.5 in) of certain cultivars, for example, Red Delicious or Golden Deli-cious, Jonathan, Gravenstein, Yellow Newton Pippin, Winesap, and Rome Beauty, are peeled, trimmed, and cut to pieces 9.5.5 mm (3/8/2 in) in thickness. The treated apple slices may be then cold stored for about 2 to allow the fungicide topenetrate the slices. Then, the slices are spread on slotted oors of natural draft or loft-type kilns, where the heated air rises through slices and dehydrates them. Drying in thekiln requires 1 , depending on the rate of air circulation. Air temperatures of about6C7C are maintained, and the fruit is turned several times during drying. typical ratio of fresh to dry mass of apples is approximately 7:1 for typical high nal moisture content of 1%2% .. This type of dry product is sometimes called an evaporated apple . Low-moisture apple slices, with less than 3% of moisture, are another dehydrated apple product. Final products may contain up to 2 ppm of SO 2. Tunnel and conveyor dryers are also often used to dry apple slices. In the tunnel dryer, the apple slices are spread onto trays at about 1 kg/m2. Typical examples of inlet and outlet air temperatures and approximate drying time for apple slices, as well as for other fruits, are presented in Table 9. Table 1 presents examples of drying conditions for apple slices, apricot, and plums in four-band-conveyor dryer (Fig. . Continuousbelt, vacuum, or other types of dryers are used for nish drying of apple pieces fromevaporated apples to low-moisture apples. Other methods, such as explosion pufng,freeze drying, foam mat, and drum drying, have all been used in experimental or relativelylow-production-scale test runs. In addition to slices, several other forms of dried apples are available. Small-size apples, dried as whole fruits, are also used for apple chop produc- tion. Apple powder (our) consists of dehydrated apples prepared
