Blackcurrant

Ribes nigrum, or Blackcurrant (cassis, cassissier, gadellier noir and groseillier noir - French; Schwarze Johannisbeere - German) is a species of Ribes berry native to central and northern Europe and northern Asia and is a perennial.

It is a small shrub growing to 1–2 m tall. The leaves are alternate, simple, 3–5 cm long and broad, and palmately lobed with five lobes, with a serrated margin. The flowers are 4–6 mm diameter, with five reddish-green to brownish petals; they are produced in racemes 5–10 cm long. When not in fruit, the plant looks similar to the redcurrant shrub, distinguished by a strong fragrance from leaves and stems.

The fruit is an edible berry 1 cm diameter, very dark purple in color, almost black, with a glossy skin and a persistent calyx at the apex, and containing several seeds dense in nutrients. An established bush can produce up to 5 kilos of berries during summer. Plants from Asia are sometimes distinguished as a separate variety Ribes nigrum var. sibiricum, or even as a distinct species Ribes cyathiforme.

Nutrients and phytochemicals

The fruit has an extraordinarily high vitamin C content (302% of the Daily Value per 100 g, table), good levels of potassium, phosphorus, iron and vitamin B5, and a broad range of other essential nutrients (nutrient table, right).

Other phytochemicals in the fruit (polyphenols/anthocyanins) have been demonstrated in laboratory experiments with potential to inhibit inflammation mechanisms suspected to be at the origin of heart disease, cancer, microbial infections or neurological disorders like Alzheimer's disease.

Major anthocyanins in blackcurrant pomace are delphinidin-3-O-glucoside, delphinidin-3-O-rutinoside, cyanidin-3-O-glucoside, and cyanidin-3-O-rutinoside which are retained in the juice concentrate among other yet unidentified polyphenols.

Blackcurrant seed oil is also rich in many nutrients, especially vitamin E and several unsaturated fatty acids including alpha-linolenic acid and gamma-linolenic acid.
