The apple (Malus domestica Borkh.) has been a well-known and sought-after species since the times of Adam and Eve. It is grown for its high quality fruit, which excels in attractiveness and good taste, being firm and juicy. Its fruit is sweet, having about 17% sugar, balanced with malic acid. Apples have remained popular throughout the ages because of their good taste, but also because they are not as perishable as many other temperate and topical fruits. They are ideally suited as a refreshment between meals. Most cultivars have a fruit size of 250–300 g, which provides about 100 calories of nutrition.
