Fuji Apples

What is Fuji Apples?

Fuji apples are typically large or very large and round, on average the size of a baseball. They contain between 9-11% sugars by weight and have a dense flesh that is sweeter and crispier than many other apple varieties, making them popular with consumers around the world. Fuji apples also have a very long shelf life compared to other apples, even without refrigeration. With refrigeration, Fuji apples can last up to 5-6 months.

Outside of Japan, the popularity of Fuji apples continues to grow. Fuji apples account for 80% of China's 20 million tons grown annually, for example. Since their introduction into the U.S. market in the 1980s, Fuji apples have continued to gain popularity with American consumers as well. A relative stranger to American supermarket shelves only 10 years ago, Fuji apples ranked at number 4 in 2003 on the US Apple Association's list of most popular apples, after Red Delicious, Golden Delicious, and Gala. Fuji apples are now grown in traditional apple-growing states such as Washington, New York, and California as demand shifts in both the domestic and foreign markets toward Fuji apples. Washington, the home of the Red Delicious and grower of half of America's apples, produces about 135,000 tons of Fuji apples each year, with only Red Delicious and Golden Delicious outweighing Fujis.

Origin Of Fuji Apples

The tree originated from Asia, where its wild ancestor is still found today. There are more than 7,500 known cultivars of apples resulting in range of desired characteristics. It should be noted however, that cultivars vary in their yield and the ultimate size of the tree, even when grown on the same rootstock. At least 55 million tonnes of apples were grown worldwide in 2005, with a value of about $10 billion. China produced about two-fifths of this total.

The apple is the pomaceous fruit of the apple tree, species Malus domestica in the rose family Rosaceae. It is one of the most widely cultivated tree fruits. The tree is small and deciduous, reaching 5–12 m tall, with a broad, often densely twiggy crown. The leaves are alternately arranged simple ovals 5–12 cm long and 3–6 cm broad on a 2–5 cm petiole with an acute tip, serrated margin and a slightly downy underside. Flowers are produced in spring simultaneous with the budding of the leaves. The flowers are white with a pink tinge that gradually fades, five petaled, 2.5–3.5 cm in diameter. The fruit matures in autumn, and is typically 5–9 cm diameter. The centre of the fruit contains five carpels arranged in a five-point star, each carpel containing one to three seeds.

Storage:

Commercially, apples can be stored for some months in controlled-atmosphere chambers to delay ethylene-induced onset of ripening. Ripening begins when the fruit is removed. For home storage, most varieties of apple can be stored for approximately two weeks, when kept at the coolest part of the refrigerator (i.e. below 5°C). Some types of apple, including the Granny Smith and Fuji, have an even longer shelf life.

Maturation and Harvest:

Cultivars vary in their yield and the ultimate size of the tree, even when grown on the same rootstock. Some cultivars, if left unpruned, will grow very large, which allows them to bear much more fruit, but makes harvesting very difficult. Mature trees typically bear 40–200 kg of apples each year, though productivity can be close to zero in poor years. Apples are harvested using three-point ladders that are designed to fit amongst the branches. Dwarf trees will bear about 10–80 kg of fruit per year.

Nutrition Facts:

An old proverb attests to the health benefits of the fruit: "An apple a day keeps the doctor away." Research suggests that apples may reduce the risk of colon cancer, prostate cancer and lung cancer. Like many fruits, apples contain Vitamin C as well as a host of other antioxidant compounds, which may reduce the risk of cancer by preventing DNA damage. The fiber content, while less than in most other fruits, helps regulate bowel movements and may thus reduce the risk of colon cancer. They may also help with heart disease, weight loss and controlling cholesterol, as they do not have any cholesterol, have fiber, which reduces cholesterol by preventing reabsorption, and are bulky for their caloric content like most fruits and vegetables.

There is evidence that in vitro, apples possess phenolic compounds which may be cancer-protective and demonstrate antioxidant activity. The predominant phenolic phytochemicals in apples are quercetin, epicatechin, and procyanidin B2.
