Malpighia emarginata is a tropical fruit-bearing shrub or small tree in the family Malpighiaceae. Common names include acerola (Portuguese pronunciation: [ɐse̞ˈɾɔ̞lɐ]), Barbados cherryWest Indian cherry[4] and wild crepemyrtle.[5] Acerola is native to South America, Southern Mexico and Central America, but is now also being grown as far north as Texas and in subtropical areas of Asia, like India. It is known for being extremely rich in vitamin C, almost as much as camu camu, although it also contains vitamins A, B1, B2 and B3 as well as carotenoids and bioflavonoids which provide important nutritive value and have antioxidant uses.[6] The vitamin C produced by the fruit is better absorbed by humans than synthetic ascorbic acid.[

Distribution

M. emarginata is originally from Yucatán, and can be found in MexicoCentral America, the CaribbeanSouth America as far south as Peru and thesouth east region in Brazil, and in the southernmost parts of the contiguous United States (southern Florida[3] and the Lower Rio Grande Valley ofTexas),.[2][3][8] It is cultivated in the tropics and subtropics throughout the world, including the Canary IslandsGhanaEthiopiaMadagascar,ZanzibarSri LankaTaiwanIndiaJavaHawaii, and Australia.[9]

[edit]Adaptation

Acerola can be propagated by seed, cutting and other methods. M. emarginata prefers dry sandy soil and full sun, and cannot endure temperatures lower than 30°F. Because of its shallow roots, it has very low tolerance to winds.

[edit]Description

Acerola is an evergreen shrub or small tree with spreading branches on a short trunk. It is usually 2–3 m (6.6–9.8 ft) tall, but sometimes reaches 6 m (20 ft) in height.[10]

[edit]Leaves

The leaves are simple ovate-lanceolate, 2–8 cm (0.79–3.1 in) long, 1–4 cm (0.39–1.6 in), and are attached to short petioles. They are oppositeovate to elliptic-lanceolate, and have entire or undulating margins with small hairs, which can irritate skin.

[edit]Flowers

Flowers are bisexual and 1–2 cm (0.39–0.79 in) in diameter. They have five[10] pale to deep pink or red[11] fringed petals, ten stamens, and six to ten glands on the calyx. There are three to five flowers per inflorescence, which are sessile or short-peduncled axillary cymes.[10]

[edit]Fruit

After 3 years trees produce significant numbers of bright red drupes 1–3 cm (0.39–1.2 in) in diameter with a mass of 3–5 g (0.11–0.18 oz). Drupes are in pairs or groups of three, and each contains three triangular seeds. The drupes are juicy and very high in vitamin C(3-46g kg-1)[12] and other nutrients. They are divided into three obscure lobes and are usually acid to subacid, giving them a sour taste,[10] but may be sweet if grown well.[13] While the nutrient composition depends on the species and environmental conditions, the most common components of acerola and their concentration range are as follow: proteins (2.1-8g), lipids (2.3-8g), carbohydrates (35.7-78g), calcium (117 mg), phosphor (171 mg), iron (2.4 mg), pyridoxine (87 mg), riboflavin (0.7 mg), thiamine (0.2 mg), water (906-920g) and dietic fibre (30g)[6]

[edit]Uses

[edit]As food

The fruit is edible and widely consumed in the species' native area, and is cultivated elsewhere for its high vitamin C content. There are 1677.6 mg of vitamin C in 100 g of fruit.[4]
  • Fruit can be used to make juices and pulps, both very rich in vitamin C and antioxidants;
  • Acerola fruit can be used to produce vitamin C concentrate;[7]
  • Baby food and juice[14]
A comparative analysis of antioxidant potency among a variety of frozen juice pulps was carried out, including the acerola fruit. Among the eleven fruits' pulps tested, acerola was the highest-scoring domestic fruit, meaning it had the most antioxidant potency, with a TEAC (Trolox equivalent antioxidant activity) score of 53.2 mmol g.[15]
Absolut Vodka released Absolut Los Angeles, a limited-edition spirit flavored with acerola, açaipomegranate, and blueberry, in July 2008.[16]

[edit]Other uses

Acerola is a popular bonsai subject because of its small leaf, fruit and fine ramification. It is also grown as an ornamental[17] and for hedges.[9]
It is one of three ingredients in a proprietary herbal medicine for allergic rhinitis.[18]
