Malpighia emarginata is a tropical fruit-bearing shrub or small tree in the family Malpighiaceae.

Synonymous names of the plant are malpighia glabra L. and malpighia punicifolia L. However, taxonomists prefer to use the name malpighia emarginata[4].

Common names include acerola cherry, Guarani cherry, Barbados cherry, West Indian cherry,[5] and wild crepe myrtle [6]. Acerola is native to Paraguay and Brazil in South America, Central America and southern Mexico, Puerto Rico, Dominican Republic and Haiti, but is now also being grown as far north as Texas and in subtropical areas of Asia, such as India.

The fruit pulp is notable for its exceptional content of vitamin C (nutrition table).

Distribution

edit

Malpighia emarginata is originally from Yucatán, and can be found in Mexico, Central America, the Caribbean, South America as far south as Peru and Colombia [7], and the southeast region of Brazil, and in the southernmost parts of the contiguous United States (southern Florida [8] and the Lower Rio Grande Valley of Texas) [8][9][10]. In Florida, it can be grown in protected locations as far north as Cape Canaveral [11]. It is cultivated in the tropics and subtropics throughout the world, including the Canary Islands, Ghana, Ethiopia, Madagascar, Zanzibar, Sri Lanka, Taiwan, India, Java, Hawaii, and Australia [12].

Production

edit

Brazil

edit

Brazil is the largest producer of acerola worldwide [13]. On 11,000 hectares, Brazil produces 32,990 tons of acerola per year. In order to preserve the genetic variability of acerola, the federal rural University of Pernambuco in Brazil established an "Acerola Active Germplasm Bank" in June 1998 [4].

Growth conditions

edit

Acerola can be propagated by seed, cutting, or other methods. It prefers dry, well-drained, sandy soil and full sun, and cannot endure temperatures lower than 30 °F/ -1 °C. Because of its shallow roots, it has very low tolerance to winds. Furthermore, a sufficient water supply is advantageous for good growth and maximum yields of large fruits. This is especially important during fruiting and flowering [14]. The optimal growth conditions are reached at a mean temperature of 26°C and 1200–1600 mm of rainfall annually [15].

Description

edit

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 [6]. The chromosome number is 2n = 40 [16].

Bark

edit

The bark of young branches is green and sparsely covered with curly-haired trichomes, which fall off with age. The greyish to brownish bark is relatively smooth and covered with conspicuous cork pores when young. With age, it is thick and cracked.

Leaves

edit

The leaves are simple ovate-lanceolate, 2–8 cm (0.79–3.15 in) long, 1–4 cm (0.39–1.57 in), and are attached to short petioles. They are opposite, ovate to elliptic-lanceolate, and have entire or undulating margins with small hairs, which can irritate the skin.

Flower

edit

The flowering of the tree happens from April to November. Flowers are bisexual and 1–2 cm (0.39–0.79 in) in diameter. They have five [6] pale to deep pink or red [17] fringed petals, 10 stamens, and six to 10 glands on the calyx. The three to five flowers per inflorescence are sessile or short-peduncled axillary cymes [6].

Fruits and seeds

edit
 
Malpighia emarginata created by Daniel Hardt

Three years after planting, trees start producing fruits. 3-4 weeks after flowering [18], a number of bright red drupes 1–3 cm (0.39–1.18 in) in diameter with a mass of 3–5 g (0.11–0.18 oz) mature. The shell of the fruit is smooth and very thin. Its shelf life of 2-3 days at ambient temperature makes it highly perishable. Drupes are in pairs or groups of three, and each contains three triangular seeds. The drupes are juicy and high in vitamin C (300–4600 mg/100g)[12] and other nutrients. They are divided into three obscure lobes and are usually acidic to subacidic, giving them a sour taste [6], but may be sweet if grown well [19]. Vitamin C content is higher in acidic varieties. Generally, vitamin C content decreases as the fruit matures.

Cultivation methods

edit

Yield and harvest

edit

Acerola flowers and fruits already in the first year after planting but increases its production in the following years, reaching up to 47kg/per plant in the sixth year[15]. The fruiting season usually extends from April to November. The fruits should be picked frequently, as they are not stored on the tree. It should be noted that ripe fruit should be handled carefully to avoid bruising and should be utilized as soon as possible or frozen for later use. Semi-ripe fruit will usually keep for several days in the refrigerator [14]. Pollination by wild insects increases the fruit yield [20].

Sowing

edit

Plants can be set at any time of the year, but the best time is spring, just before the rainy season. Choose a location with good water drainage and in a sheltered spot [14].

Pests and diseases

edit

Malpighia emarginata is a host plant for the caterpillars of the white-patched skipper (Chiomara asychis) [21], Florida duskywing (Ephyriades brunneus) [22], and brown-banded skipper (Timochares ruptifasciatus) [23]. Larvae of the acerola weevil (Anthonomus macromalus) feed on the fruits, while adults consume young leaves [24].

Nutritional values

edit

Acerola fruit is 91% water, and 8% carbohydrates, and contains negligible protein and fat (table). The fruit also supplies manganese at 29% DV, while other micronutrients are uniformly low in content (table). In 100 grams (3.5 oz) reference amount, acerola fruit provides an exceptional content of vitamin C at some 20 times the Daily Value (DV) (table). This vitamin C is better absorbed by humans than ascorbic acid from synthetic sources [25]. Whereas the content of sugar, soluble solids and titratable acids increases, the vitamin C content decreases with the ripening process of the fruit. Therefore, the immature green fruit is harvested for industrial use of the vitamin C.[26] Besides the high vitamin C content, acerola also contains phytonutrients like phenolic acids, flavonoids, anthocyanins, and carotenoids [27].

Uses

edit

The sour fruits of acerola are among those with the highest content of vitamin C; 100 g of fresh juice contains up to about 1000-1500 mg of the vitamin. Therefore, acerola cherry is used as a food supplement. Acerola fruit can also be eaten raw. Usually, it is used as a juice that is mixed with other, usually sweeter fruit juices. The fruit cannot be exported because it is so soft and juicy that it must be processed immediately after harvest. Juices are produced from the acerola cherry, which are sold pasteurized or frozen. There is also acerola powder available, which is obtained by the spray-drying process. In the meantime, the gentlest method, freeze-drying, has gained acceptance. Popular is the use of juice, pulp, concentrate and powder.

  • as vitamin enrichment of other fruit juices,
  • as an acid additive to enhance the intrinsic flavour of other fruits,
  • for the production of ice cream, jam and jelly.

Other uses

edit

Acerola is a popular bonsai subject because of its small leaf and fruit, and fine ramification. It is also grown as an ornamental [28] and for hedges [29] Because acerola also contains pigments like anthocyanins and carotenoids, it could also be used as a food colorant [4].
