Crispy dried apples, using hot drying, cold drying, or freeze dryer

Dried sliced ​​apples are one of the main ingredients in fruit detox products or fruit teas. The apples used for drying are mainly Western apples, pear apples, or red apples; the type of apple used will depend on the specific product. What is the most effective method for drying apples to achieve a crispy texture? In this article, we will explore various drying methods for apples.

Apples are characterized by their firm texture, lower water content, high fiber, and moderate sweetness, making them easier to dry into a crispy texture compared to other fruits. For thinly sliced ​​apples (5-10mm thick), both specialized fruit dryers and conventional hot air dryers can be used for drying. However, to achieve good quality dried fruit with vibrant color and preserved nutrients, lower drying temperatures are necessary; the lower the better, resulting in a more beautiful color, less shrinkage, and better nutrient retention. Therefore, using a cold air dryer ensures product quality suitable for common uses such as eating or making fruit detox drinks and fruit teas.

Dried apples have many practical applications, such as making apple tea, weight-loss drinks, fruit detox drinks, and apple powder. The way they are used varies depending on the individual and age group. Women often use them in the form of fruit detox drinks daily. Middle-aged and older people often use them in the form of fruit tea combined with other herbs such as rose buds, camellia flowers, jasmine flowers, dried longan, etc. Apple powder is used in many products such as cakes, beverages, etc.

A freeze dryer is suitable for sliced ​​apples and pears. If we only need to use the product as shown in the picture, a freeze dryer is the most suitable choice, drying quickly, evenly, with beautiful color, preserving nutrients and flavor. The size of the dried product may shrink slightly, but it does not affect the product’s value. For higher-end products on the market, where dried fruits need to retain their natural shape and color, freeze-drying is necessary to ensure the requirements are met, especially for fruits with high water content such as durian, dragon fruit, ripe mango, kiwi, strawberries, tomatoes, and cordyceps mushrooms, which require freeze-drying to maintain their natural shape. For conventionally dried products, freeze-drying is not recommended because the machine is very expensive and inefficient when the price of the dried product is low.
