Nuts vary in the amount of tannins they contain. Some species of acorns of oak contain large amounts. For example, acorns of Quercus robur and Quercus petraea in Poland were found to contain 2.4–5.2% and 2.6–4.8% tannins as a proportion of dry matter, [51] but the tannins can be removed by leaching in water so that the acorns become edible ...
Many other foods and beverages may also contain proanthocyanidins, but few attain the levels found in red grape seeds and skins, [6] with a notable exception being aronia, which has the highest recorded level of proanthocyanidins among fruits assessed to date (664 milligrams per 100 g).
Mainly found in the fruit skins and seeds, high levels of polyphenols may reflect only the measured extractable polyphenol (EPP) content of a fruit which may also contain non-extractable polyphenols. Black tea contains high amounts of polyphenol and makes up for 20% of its weight. [20] Concentration can be made by ultrafiltration. [21]

However, bilberry, cranberry, black currant, green tea, black tea, and other plants also contain these flavonoids. [3] Procyanidins can also be isolated from Quercus petraea and Q. robur heartwood (wine barrel oaks). [4] Açaí oil, obtained from the fruit of the açaí palm (Euterpe oleracea), is rich in numerous procyanidin oligomers. [5]
