The blackcurrant or black currant (Ribes nigrum) is a woody shrub in the family Grossulariaceae grown for its piquant berries. It is native to temperate parts of central and northern Europe and northern Asia where it prefers damp fertile soils and is widely cultivated both commercially and domestically. It is winterhardy, but cold weather at flowering time during the spring reduces the size of the crop. Bunches of small, glossy black fruit develop along the stems in the summer and can be harvested by hand or by machine. The raw fruit is particularly rich in vitamin C and polyphenol phytochemicals. Blackcurrants can be eaten raw but are usually cooked in a variety of sweet or savoury dishes. They are used to make jams, jellies and syrups and are grown commercially for the juice market. The fruit is also used in the preparation of alcoholic beverages and both fruit and foliage have uses in traditional medicine and the preparation of dyes.
As a crop, the blackcurrant suffers from several pests and diseases. The most serious disease is reversion, caused by a virus transmitted by the blackcurrant gall mite. Another is white pine blister rust which alternates between two unrelated hosts, one in the genus Ribes (blackcurrant included) and the other a white pine. This fungus caused damage to forests when the fruit was first introduced into North America, where the native white pines have no genetic resistance to the disease. As a result, the blackcurrant has for most of the 20th century been subject to restrictions in parts of the United States as a disease vector. The effectiveness of these restrictions is questionable, since other Ribes species also host the disease and are native to North America.
Breeding is being undertaken in Scotland, Poland, Lithuania, Norway, and New Zealand to produce fruit with better eating qualities and bushes with greater hardiness and disease resistance.
Ribes nigrum, the blackcurrant, is a medium-sized shrub, growing to 1.5 by 1.5 metres (4.9 by 4.9 ft). The leaves are alternate, simple, 3 to 5 cm (1.2 to 2.0 in) broad and long with five palmate lobes and a serrated margin. All parts of the plant are strongly aromatic. The flowers are produced in racemes known as “strigs” up to 8 cm (3 in) long containing ten to twenty flowers, each about 8 mm (0.3 in) in diameter. Each flower has a hairy calyx with yellow glands, the five lobes of which are longer than the inconspicuous petals. There are five stamens surrounding the stigma and style and two fused carpels. The flowers open in succession from the base of the strig and are mostly insect pollinated, but some pollen is distributed by the wind. A pollen grain landing on a stigma will germinate and send a slender pollen tube down the style to the ovule. In warm weather this takes about 48 hours but in cold weather it may take a week, and by that time, the ovule may have passed the stage where it is receptive. If fewer than about 35 ovules are fertilised, the fruit may not be able to develop and will fall prematurely. Frost can damage both unopened and open flowers when the temperature falls below −1.9 °C (28.6 °F). The flowers at the base of the strig are more protected by the foliage and are less likely to be damaged.
In midsummer the strigs of green fruit ripen to edible berries, very dark purple in colour, almost black, with glossy skins and persistent calyxes at the apex, each containing many seeds. An established bush can produce about 4.5 kilograms (10 pounds) of fruit each year.
Plants from Northern Asia are sometimes distinguished as a separate variety, Ribes nigrum var. sibiricum, of which Ribes cyathiforme is considered a synonym.
The blackcurrant is native to northern Europe and Asia. It was cultivated in Russia by the 11th century when it was present in monastery gardens and also grown in towns and settlements. Cultivation in Europe is thought to have started around the last decades of the 17th century. Decoction of the leaves, bark or roots was also used as traditional remedies.
During World War II, most fruits rich in vitamin C, such as oranges, became difficult to obtain in the United Kingdom. Since blackcurrant berries are a rich source of the vitamin and blackcurrant plants are suitable for growing in the UK climate, the British Government encouraged their cultivation and soon the yield of the nation’s crop increased significantly. From 1942 onwards, blackcurrant syrup was distributed free of charge to children under the age of two, and this may have given rise to the lasting popularity of blackcurrant as a flavouring in Britain.In Britain the commercial crop is completely mechanised and about 1,400 hectares of the fruit are grown, mostly under contract to the juicing industry. Commercially, most large-scale cultivation of blackcurrants is done in eastern Europe for the juice and juice concentrate market. As of 2017, major cultivation efforts to improve fruit characteristics occurred in Scotland, New Zealand, and Poland.
Blackcurrants were once popular in the United States as well, but became less common in the 20th century after currant farming was banned in the early 1900s, when blackcurrants, as a vector of white pine blister rust, were considered a threat to the U.S. logging industry. The federal ban on growing currants was shifted to jurisdiction of individual states in 1966, and was lifted in New York State in 2003 through the efforts of horticulturist Greg Quinn. As a result, currant growing is making a comeback in New York, Vermont, Connecticut and Oregon. However, several statewide bans still exist including Maine, New Hampshire, Virginia, Ohio, and Massachusetts. Since the American federal ban curtailed currant production nationally for nearly a century, the fruit remains largely unknown in the United States, and has yet to regain its previous popularity to levels enjoyed in Europe or New Zealand. Owing to its unique flavour and richness in polyphenols, dietary fibre and essential nutrients, awareness and popularity of blackcurrant is once again growing, with a number of consumer products entering the U.S. market
21 Amazing Benefits
1.Keeps Our Cardiovascular System Healthy
Eating blackcurrant on a regular and moderate basis is very beneficial for our heart as it helps in keeping our heart healthy and reduces the risk of various cardiovascular problems like heart attack, stroke, irregular heartbeat etc. This benefit of blackcurrant is mainly due to the presence of polyphenolic compounds like flavonoids in them.
In addition to this, they are also a rich source of antioxidants that prevents the inner walls of our arteries from oxidative damage and also minimizes the formation of toxic substances on the interior walls of blood vessels. This helps in the smoother flow of blood through our cardiovascular system and thus keeps it healthy.
2.Helps In Controlling High Blood Pressure
Blackcurrant is very beneficial for the individuals who are struggling with high blood pressure. Regular and moderate consumption of blackcurrant is very beneficial for reducing the risk of high blood pressure or hypertension because of the presence of potassium in it. Potassium is a natural vasodilator which relaxes our blood vessels and ensures smooth flow of blood and thus helps in regulating blood pressure.
3.Is A Rich Source of Omega-3 Fatty Acid
Blackcurrants are also a good source of Omega-3 fatty acids and presence of Omega-3 makes them very beneficial for regulating cholesterol level in our body. Eating blackcurrant on a regular and moderate basis lowers LDL cholesterol level ( aka LDL cholesterol) and at the same time, boosts good cholesterol level ( aka HDL cholesterol). Too much LDL cholesterol is bad for our health as it gets deposited within the arteries and blood vessels block them and thus increases the risk of various cardiovascular problems like heart attack, heart stroke, irregular heartbeat etc.
By regulating cholesterol level, blackcurrant not only protects us from the various cardiovascular problem but also helps in regulating blood pressure, which is a major health problem that affects millions of people all over the world.
4.Provides Anticarcinogenic Benefits
Blackcurrants are anti-carcinogenic in nature which means they reduce the risk of development of cancer in our body. This benefit of blackcurrant is mainly due to the presence of antioxidants like Vitamin C, beta-carotene, cryptoxanthin, zeaxanthin etc. in them.
These antioxidants and antioxidantal compounds fight with the free radicals of our body, stabilizes them and thus prevents them from causing oxidative damage to our body cells and thus reduces the risk of cancer. Free radicals are nothing but the unstabilized ions that get formed mainly during the oxidation process in our body. As they are unstabilized, so they steal electrons from the molecules of our body cells, and while doing so they cause oxidative damage to them.
Regular and moderate intake of blackcurrant prevents our body cells from this oxidative damage and thus reduces the risk of various cancer(s).
