Apple ( Malus domestica )

  

Fruit Warehouse | Apple ( Malus domestica ) |  Apples were Brought to North America with colonists in the 17th century, and the first apple orchard on the North American continent was said to be near Boston in 1625. Improved transportation of fresh apples by train and road replaced the necessity for storage. Controlled atmosphere facilities use high humidity and low oxygen and carbon dioxide levels to maintain fruit Freshness.


Domestic apples are propagated by grafting Generally, although the wild apples grow readily from seed. Apples are Often eaten raw, but can also be found in many foods (ESPECIALLY desserts) and drinks. The apple tree was Perhaps the earliest tree to be cultivated, and its fruits have been improved through selection over Thousands of years.


The apple is the fruit of the pomaceous apple tree, species Malus domestica in the rose family (Rosaceae). Apples grow on small, deciduous trees. In 2010, the fruit's genome was decoded, leading to new understandings of disease control and selective breeding in apple production. There are more than 7.500 known cultivars of apples, resulting in a range of Desired characteristics.



One form of apple allergy, Often found in northern Europe, is called birch-apple syndrome, and is found in people WHO are also allergic to birch pollen. The variety of apple, maturity and storage conditions can change the amount of allergen present in individual fruits. Long storage times can increase of the amount of proteins That cause birch-apple syndrome.


Individuals with this form of allergy can also develop reactions to other fruits and nuts. Cooking does not break down the protein Causing this particular reaction, so affected individuals can not eat either raw or cooked apples. Breeding Efforts have yet to Produce a hypoallergenic fruit for either of the two types of apple allergy.


The Proverb "An apple a day keeps the doctor away.", Addressing the health effects of the fruit, dates from 19th century Wales. Research Suggests That apples may Reduced the risk of colon cancer, prostate cancer and lung cancer. Compared to many other fruits and vegetables, apples contain Relatively low amounts of vitamin C, but are a rich source of other antioxidant compounds. The fiber contained in apples reduces cholesterol by Preventing reabsorption, and (like most fruits and vegetables) They are bulky for Their caloric content. However, apple seeds are mildly poisonous, containing a small amount of amygdalin, a cyanogenic glycoside.


The predominant phenolic phytochemicals in apples are quercetin, epicatechin, and procyanidin B2. Researchers at the Chinese University of Hong Kong WHO Discovered That fruit flies were fed an apple extract lived 10% longer than other WHO flies were fed a normal diet.
