exGrape™ Grape extracts
exGrape™ Grape extracts
These highly standardised grape extracts contain a broad spectrum of polyphenols with many properties that are beneficial to health. In vitro and in vivo studies indicate that wine grape polyphenols exhibit antioxidant, antithrombotic and blood pressure-reducing properties and thereby promote cardiovascular health. In addition, a human study conducted in healthy subjects at high metabolic risk revealed that the grape polyphenol extract exGrape™ TOTAL can counteract high oxidative stress, lipid peroxidation and insulin resistance.
The extracts are produced exclusively using grapes cultivated in France and directly processed on site in a resourceefficient manner by our partner GrapSud. The resultant biomass and the process water that has been treated in a wastewater treatment plant are returned to the vineyard to maintain soil fertility.
The skins and seeds from Merlot, Cabernet Sauvignon and Grenache grapes are used to produce the exGrape™ TOTAL grape extracts. Early harvest Chardonnay grapes from the Champagne region have the highest OPC content and are used to produce the exGrape™ SEED extracts.
Extraction ratio:
500 kg grape skins and seeds => 1 kg exGrape™ SEED
25 kg grape seeds => 1 kg exGrape™ SEED
Following extraction, spray-drying and agglomeration is carried out without the use of carrier substances (F: fine powder; G: agglomerated powder). The agglomerated powders are characterised by improved product handling (free flowing, reduced dust in production) and increased solubility.
In addition, the results of HPLC analysis, with a chromatogram, and quantification of the monomeric, dimeric, trimeric, tetrameric and pentameric proanthocyanidins based on the new Kuhnert-Winterhalter method are available on request for exGrape™ SEED.
