Article: Acerola (Malpighia emarginata, M. glabra)


Malpighia emarginataM. glabra

Family: Malpighiaceae

INTRODUCTION

Acerola is the common name assigned to two species in the tropical nance family (Malpighiaceae) — Malpighia emarginata and M. glabra. Both are called Barbados cherry and West Indian cherry by various sources that are not always in agreement as to which is which.1,2 Some sources even classify them as the same species.3 Malpighia glabra is a large shrub or small tree that can grow as tall as 20 feet (6.09 m).4 The pink or lavender flowers are succeeded by red drupes, i.e., stone fruits (fleshy fruits with one seed that do not split open upon maturation) sometimes referred to as acerola cherries. This species is native to the Lesser Antilles from St. Croix Island (US Insular Area) to Trinidad and Tobago, Curaçao (Netherlands), and Margarita Island (Venezuela), as well as neighboring northern South America into Brazil. Malpighia glabra was introduced to cultivation in Cuba, Jamaica, and Puerto Rico (US Insular Area).4

Malpighia emarginata also is a shrub or small tree that grows up to 20 feet tall.5 The flowers and fruit are very similar to M. glabraMalpighia emarginata is indigenous to southern Mexico, Central America, and the northern region of South America. It was introduced to Brazil, now the world’s biggest producer, in the mid-20th century.5

The fruit of both species is used interchangeably and is round, bright red, one-half to one inch (1.25-2.5 cm) in diameter, with juicy, acidic pulp.4

HISTORY AND CULTURAL SIGNIFICANCE

Acerola fruit is high in vitamin C in the form of ascorbic acid.4 The fruit’s ascorbic acid content is dependent upon various factors including how and where the plant is grown, how much sunlight it receives, and at what stage of ripeness the fruit is harvested, as well as the individual plant’s genetic makeup. The amount of ascorbic acid can range from up to 4,500 mg per 100 g of edible fruit if harvested when still green, or 2,000 mg ascorbic acid per 100 g of edible fruit if harvested when very ripe. Acerola is surpassed in vitamin C content by very few sources, chief among them kakadu plum (Terminalia latipes ssp. psilocarpa, syn. Terminalia ferdinandiana, Combretaceae), camu-camu (Myrciaria dubia, Myrtaceae), and rose hips (Rosa spp., Rosaceae).6 As with many plants, some of the beneficial effects are diminished by heat. For example, jelly made from acerola may contain only 500 to 1,900 mg ascorbic acid per 100 g of fruit.4

Malpighia glabra juice is popular in Brazil, and the fruit is consumed as a natural remedy.7 The fruit has astringent,7,8 anti-inflammatory, stimulant, and diuretic properties.7 In Brazil, the fresh fruit is used for cardiovascular support, diarrhea (Brazil, Guatemala), dysentery (Brazil, Venezuela), fever (Brazil, Mexico), wound healing (Brazil), and as nutritional support for convalescents and those who require treatment for anemia, high cholesterol, diabetes, liver conditions, rheumatism, and tuberculosis.7 It also has been used to treat hepatitis, breast conditions (Venezuela),7 and tenesmus (a symptom characterized by a sensation of constantly needing to pass stools although the colon is empty).8

In the United States, acerola is used as a food (e.g., juice) or as a component of dietary supplement products.9 For example, extracts of the whole fruit are found in vitamin C supplements, sometimes in combination with other sources of vitamin C such as ascorbic acid and/or sodium ascorbate.

The ripe fruit, which is pleasant to taste despite being slightly sour, is used in making jams, jellies, juice, ice cream, pies, and preserves, as well as flavoring for cocktails.10 It also is used in making liqueurs.8

CURRENT AUTHORIZED USES IN COSMETICS, FOODS, AND MEDICINES

For beverage food products, the United States Food and Drug Administration requires a minimum Brix Level* of 6.0 for acerola single-strength (100% juice) products.9 In its International Food Standards, Codex Alimentarius set a minimum Brix Level of 6.5 for reconstituted acerola fruit juices and reconstituted acerola purée, and a minimum juice and/or purée content (% v/v) of 25.0% for acerola fruit nectars.11

For conventional (non-organic) cultivation of acerola, the US Environmental Protection Agency has established maximum allowable limits for residues of various acaricides (e.g., bifenazate), fungicides (e.g., azoxystrobin, fludioxonil), herbicides (e.g., carfentrazone-ethyl, glyphosate, paraquat), insecticides (e.g., buprofezin, chlorantraniliprole, fenpropathrin, imidacloprid, methoxyfenozide, spinetoram, spinosad, spirotetramat), and pesticides (e.g., pyriproxyfen).12 There are, however, more than 20 producers of certified organic acerola fruit listed in the United States Department of Agriculture National Organic Program (NOP) database of operators, most of which are situated in Brazil, but also in Costa Rica and Peru.

In Canada, acerola is classified as a medicinal ingredient and is listed as a complementary ingredient in the “Workout Supplements” monograph at a maximum daily dose of 48 g of fruit.13 At non-therapeutic dosages, other defined acerola substances are permitted for use as non-medicinal ingredients of licensed natural health products (NHPs).14 For example, acerola fruit juice, fruit juice concentrate, and/or fruit extract can be used as non-medicinal flavor-enhancing ingredients. Dried acerola fruit also may be used as a flavor enhancer or preservative antioxidant, except in vitamin C products. In such cases, acerola must be declared as a source of the medicinal ingredient vitamin C for oral vitamin C products, or for products making claims per the NHP Directorate vitamin C monograph, if the quantity of vitamin C provided is above the lower medicinal limit as stated in the monograph. At the time of this writing (August 2014), there were more than 250 licensed NHPs listing either “acerola” or “Malpighia glabra” as a medicinal ingredient and more than 120 licensed NHPs listing acerola as a non-medicinal ingredient.15

In the European Union (EU), acerola fruit has been on the market as a food or food ingredient and was consumed to a significant degree prior to May 15, 1997; therefore, its presence in the EU market is not subject to the Novel Food Regulation No. 258/97.16 The European Food Safety Authority issued a scientific opinion on substantiation for health claims related to vitamin C, including those made for acerola fruit products.17 Proposed wording of acceptable claims for products containing acerola fruit at a daily amount equivalent to 12 mg vitamin C include the following: “Vitamin C can contribute to the reduction of tiredness and fatigue,” “Vitamin C contributes to normal psychological functions,” “Vitamin C contributes to the regeneration of the reduced form of vitamin E,” “Vitamin C contributes to normal energy-yielding metabolism,” “Vitamin C contributes to a normal function of the immune system,” and “Vitamin C contributes to the protection of cell constituents from oxidative damage.”

Several acerola ingredients are listed for use in cosmetic products by the European Commission Health and Consumers Directorate General.18 For example, “Malpighia Glabra Fruit,” “Malpighia Glabra Fruit Extract,” “Malpighia Glabra Fruit Juice” (juice expressed from the fruit), “Malpighia Glabra Fruit Water” (aqueous solution of the steam distillates obtained from the fruit), and “Hydrolyzed Acerola Fruit” (hydrolysate of the fruit derived by acid, enzyme, or other method of hydrolysis) all are listed as skin-conditioning substances; “Malpighia Emarginata Fruit Extract” and “Malpighia Emarginata Seed Extract” both are listed for hair- and skin-conditioning functions; and “Malpighia Emarginata Fruit Powder” is listed as an absorbent (takes up water- and/or oil-soluble dissolved or finely dispersed substances).

MODERN RESEARCH

In laboratory experiments, acerola has exhibited the following actions: acetylcholinesterase inhibition,19 antigenotoxic,20,21 antioxidant,20-23 anti-inflammatory,22 free radical scavenging,24 inhibition of the formation of both alpha-glucosidase and advanced glycation end product,24 cytotoxic against tumor cell lines (human oral squamous cell carcinoma and human submandibular gland carcinoma),25 antibacterial,25 nitric oxide production inhibition,26 and antifungal.27

Unfortunately, relatively few human clinical studies have investigated acerola’s medicinal benefits as it is consumed mainly as a food.

A clinical study published in 2011 explored the efficacy of a combination product in the treatment of recurrent upper respiratory tract infections in children.28 The product, Imoviral® Junior (100 mg 4% echinacoside from Echinacea angustifolia [Asteraceae], arabinogalactan [amount not stated], 265 mg acerola, 50 mg beta-glucan, 7 mg zinc [extraction method not stated]; Cristalfarma; Milan, Italy), was given to 37 children with recurrent pharyngotonsillitis (inflammation of the pharynx and tonsils, characterized by sore throat) or otitis media (middle ear infection) at the dosage of one sachet per day (dissolved in water) for two weeks per month for three months. The cycle was repeated once and a follow-up was conducted at six months. The mean number of inflammatory episodes decreased from 3±2.19 during the six months prior to treatment to 1±0.93 during the six months following treatment. At the completion of the treatment, 77% of the children reported decreased frequency of chronic inflammation. Overall, parents expressed general satisfaction and a better quality of life for the children treated.

A 2012 single-stage, phase IV, prospective, non-comparative, open clinical study investigated a combination product intended to counteract the effects of skin aging.29 Fifty women, 35 to 60 years of age, with skin phototypes I (pale, with light eyes and hair, who frequently burn and rarely tan) to III (darker white skin, who tan after initial burn) took two tablets per day with food for 120 days of Imedeen® (Biomarine Complex™, an extract of marine proteins and polysaccharides, and 14.8 mg LycoPhence GS®, composed of lycopene, grape seed extract, and 30 mg acerola extract; Ferrosan A/S; Copenhagen, Denmark). Concurrently, the subjects used Episol® SPF 15 lotion (Mantecorp Indústria Quimíca e Farmacêutica Ltda.; Rio de Janeiro, Brazil) on the face, twice daily, in the morning and at lunch. Results obtained from analysis of clinical response assessment questionnaires showed that gradual and statistically significant clinical improvement in wrinkles, fine lines, redness, hydration, sebum, and smoothness was experienced with daily use.

In 2011, a crossover, experimental study in Japan investigated the bioavailability of ascorbic acid in humans.30 Healthy male volunteers (number not stated, aged 22 to 26 years, non-smokers not taking high-dose vitamin C supplements) took a single oral dose of ascorbic acid (50, 100, 200, or 500 mg with 100 ml distilled water). Blood was collected and centrifuged every half hour for three-and-a-half hours and at hours four, five, and six after the dose. Additionally, urine samples were collected and their volume recorded every one to two hours up to six hours after the dose. After an overnight fast, the same procedure was followed but with the subjects drinking 100 ml acerola juice (frozen mature fruit obtained from Nichirei do Brazil; Recife, Brazil) diluted with water containing 50 mg ascorbic acid. Results showed that acerola juice promoted the absorption of ascorbic acid in blood plasma and suppressed its excretion in urine better than ascorbic acid alone.

FUTURE OUTLOOK

The main production areas and trading centers for acerola fruit ingredients are in South American countries, particularly Brazil.31 Early 2014 market reports indicated flat demand for most fruit juices including acerola, which may be linked to negative publicity surrounding fruit juice consumption (due to their naturally occurring sugar levels). Prices for acerola fruit juice ingredients also have declined because the market is well supplied. Indicative prices from April through July 2014 were $1,150 to $1,200 per metric ton (CFR Rotterdam) for frozen single strength from Brazil and $3,000 to $3,100 per metric ton (FOB Santos) for origin frozen concentrate (20-22 brix clear) from Brazil.

One of the NOP certified organic producers of acerola is “Fazenda Amway Nutrilite Do Brasil Ltda – Nutribotânica” (Ubajara, Brazil), also affiliated with Trout Lake Farm LLC (Trout Lake, Washington).32 Fazenda Nutribotânica is the largest Nutrilite® farm, producing acerola fruit year-round on 1,660 hectares, and providing 100% of the natural ascorbic acid used in Nutrilite products. Since 1999, the Fazenda Nutribotânica farm has been inspected and certified by Instituto Biodinâmico.33 In addition to operating under organic agriculture standards, the farm has implemented biodynamic standards and has Demeter biodynamic certification. Fazenda Nutribotânica claims to be the world’s largest grower of certified organic and biodynamic acerola fruit.

In collaboration with Nutrilite, the Brazilian Agricultural Research Corporation — or EMBRAPA (Empresa Brasileira de Pesquisa Agropecuária) — developed a new acerola variety known as “BRS 366 Jaburu,” which yields 100 kg of fruit per plant annually, corresponding to about 57 metric tons per hectare.34 EMBRAPA states that this is an approximately 20% higher yield than the second most productive variety known as Mineria. The fruits are picked green, when the vitamin C levels are twice that of the ripe fruit. According to EMBRAPA, the new cultivar has a competitive advantage over others because it is well suited to both manual and mechanized harvesting.34 Other sources report that the average yields for acerola in the Brazilian northeast are 40 or more tons per hectare compared to 25 tons in other regions.35

The total area of acerola cultivation in Brazil is estimated to be more than 10,000 hectares, with the highest production occurring in the northeastern state of Bahia, followed by the nearby northeastern states of Pernambuco, Ceará, and Paraíba.36 Annual fruit production in Brazil is approximately 33,000 metric tons. About 37% to 43% of the annual crop is exported, with primary destination markets comprising the United States, Germany, France, and Japan.

According to natural products industry insiders, a significant amount of the global supply of acerola material is reportedly adulterated with exogenous L-ascorbic acid, some of which may be chemically synthesized and/or produced from genetically engineered starting materials. For many years, L-ascorbic acid had been produced mainly by chemical synthesis (Reichstein process), but there are new biotechnological approaches, e.g., involving the epiphytic bacterium Erwinia herbicola (Enterobacteriaceae) strain genetically engineered to contain a gene from the Gram-positive bacterium Corynebacterium spp. (Corynebacteriaceae), which converts glucose to 2-ketogulonic acid and can then be converted to ascorbic acid, among other novel biotech methods.37 Methodologies to determine the presence or absence of biotech or synthetic L-ascorbic acid in acerola products have been developed and validated, including Isotope Ratio Mass Spectrometry (13C-IRMS-AOAC 998.12).38 It is recommended that buyers of natural acerola ingredients and products work with independent laboratories applying this methodology in order to verify authenticity.

Although the so-called “super fruit” market is somewhat crowded, and acerola berries compete in this arena against other more popular Brazilian exports such as açaí (Euterpe oleracea, Arecaceae) berries, the market for all things organic and biodynamic continues to grow. With an increasing number of certified organic acerola operations, this is an area that may grow faster than conventional acerola product demand. There is also a growing niche for non-synthetic, food-based vitamin products for which acerola powders and extracts can play a role as a source of natural, plant-based vitamin C.
