Antioxidant value of black
currant
Antioxidant capacity of black currant varies with organ, season, and cultivar.

Small berries such as black currant constitute one of the important sources of
potential health-promoting phytochemicals because these fruits are rich sources
of compounds with high antioxidant properties. In this work, antioxidant
capacities of different parts (buds, leaves, fruits) of various black currant
cultivars were compared throughout the growing season with the aim to prepare
extracts with high antioxidant capacity. Buds (opened, at the end of March) and
leaves (in June) had a higher content in phenolics and antioxidants than fully
ripened berries (in July) and the best yield (per branch) was obtained with the
leaves collected in June due to their higher biomass. The differences observed
among the eight black currant cultivars tested were small. Concerning flavonols,
Quercetin was
dominant in all organs and cultivars, myricetin varied widely among the
cultivars, and kampferol was very low.
Black current seed questions
Q. There are two types of currant seed oil in the market: refined and
unrefined. Can you please tell me which one is better to use.
A. We don't have much experience with currant seed oil, but our
impression would be that unrefined currant seed oil would be preferable.
Press release by Cyvex Nutrition
raw material supplier
October 2007 - Cyvex Nutrition has stepped up its supply of Black Currant
Extract powder standardized to 25 percent anthocyanins. Black Currant has been
shown to provide support to vision health. One study, for example, demonstrated
that the anthocyanins in black currant influenced the regeneration of rhodopsin.
“There is strengthening scientific interest and commercial excitement
surrounding black currant and its health potential,” says Charlene Lee,
executive vice president and general manager of Cyvex Nutrition. “Our Black
Currant Extract is the most potent berry extract available on the market
providing enhanced levels of anthocyanins.” Lee adds that Black Currant Extract
is not only a superior source of berry antioxidants and anthocyanins, it is a
more economically friendly choice as well. “In the marketplace, black currant is
less expensive, making it a terrific choice for vision support and antioxidant
formulas.” Black Currant Extract from Cyvex Nutrition is one of the newer
additions to Cyvex’ growing portfolio of specific antioxidants for health
promotion products. For more than 23 years, Cyvex Nutrition has continued its
leadership role in pioneering antioxidant raw materials. 1. Matsumoto H, et al
(2003) “Stimulatory effect of cyanidin 3-glycosides on the regeneration of
rhodopsin.” J Agric Food Chem. 51, 3560-3.
Comments: We will await human research with black currant extract
to see how well this raw material works for eyesight improvement.
Press release by Jarrow Formulas
December 2008 - Los Angeles-based Jarrow Formulas announces 2 new blackcurrant
offerings. In addition to its Blackcurrant plus Lutein and Pomegranate +
Blackcurrant concentrate products, Jarrow introduces Blackcurrant capsules and
Blackcurrant concentrate to its blackcurrant category. The introduction of
Blackcurrant capsules and Blackcurrant concentrate is a significant addition to
the existing blackcurrant offerings because it allows consumers a convenient
standalone choice among Jarrow Formulas’ blackcurrant supplements. Blackcurrant
capsules contain blackcurrant freeze-dried extract, consisting of anthocyanins
specifically studied for promoting eye comfort and antioxidant protection. New
Zealand blackcurrant is an antioxidant-rich berry due to the high content of
polyphenol pigments (anthocyanosides) that lend the berries their rich purple
color. Its capacity in reducing the oxidative damage caused by free radicals and
reactive oxygen species, such as hydrogen peroxide, is similar to that of
blueberry. Blackcurrants are particularly noted for their protective effects on
eye health, eye discomfort and visual fatigue, especially eye fatigue associated
with chronic exposure to computer and television screens. These effects may be
due to its high concentration of the polyphenols delphinidin-3-rutinoside and
cyanidin-3-rutinoside. New Zealand blackcurrants often contain more
polyphenols than European blackcurrants and are free of pesticides. All of
Jarrow Formulas blackcurrant offerings are made with 100% New Zealand
blackcurrants.
