Antioxidant Rich Foods There are several studies on the chemical composition of chokeberry berries 25-28 and juices 29 However, none of them examines the relationship between the chemical composition of the fruit and the chemical composition and antioxidant activity of the functional a ntioxidant foods derived from it. The total polyphenol content of the chokeberry fruits varied between 1022 mg/100 g FW and 1795 mg/100 g FW and the antioxidant ORAC activity between 109 µmol TE/g and 191 µmol TE/g FW. We also studied the relationship between berry and chemical composition and the antioxidant activity of aronia-functional drinks - juices and nectars. 1. Oszmiański J, Lachowicz S. Effect of production of dried fruits and juice from aronia melanocarpa L. (Aronia melanocarpa L.) on the content and antioxidant activity of bioactive compounds. Chokeberry fruits are rich in phenolic compounds, and their content depends on the type of fruit and reaches values of up to 3. 000 mg GEA/100 g FW 29 Products derived from chokeberry, mainly juices, are characterised by a significantly lower TPC than expected, due to the fact that when juices are processed by the traditional pressing method, most of the phenolic compounds present in the fruit are retained in the pomace due to non-covalent bonds within the cell wall 30 In the present study the content of polyphenols was determined at values of 281. 5 to 558.0 mg GAE/100 ml juice was determined. A. prunifolia, a violet chokeberry berry, is a hybrid between black chokeberry and red chokeberry (A. arbutifolia) 45 Furthermore, factors such as variety, fertilisation, berry ripening, harvest date and habitat/location may have a different influence on the amount and profile of phenols in chokeberry fruit 46 and thus on foods high in antioxidants. 5. denev P.N.

Bioavailability and antioxidant activity of the polyphenols of black chokeberry melanocarpa (chokeberry melanocarpa): In vitro and in vivo evidence and possible mechanisms of action: An overview.
The effects of climatic conditions on the quality characteristics of the fruits, the phenolic compounds and the antioxidant capacity of chokeberry juice (chokeberry melanocarpa) were investigated over three consecutive years. With science proving significant health benefits, farmers planting large areas of land and the media increasingly promoting their happiness, it is only a matter of time before chokeberry, the North American super berry, comes to the fore in juices, jams, jellies and many other products. Chokeberry melanocarpa (black chokeberry) has attracted scientific interest because of its deep purple, almost black pigmentation, which is due to its dense content of polyphenols, especially anthocyanins. The total polyphenol content is 1752 mg per 100 g dry weight, the content of 22 anthocyanins is 1480 mg per 100 g dry weight and the proanthocyanidin concentration is 664 mg per 100 g fresh weight. Touted as a superfood - and better than other superfoods like the acai berry because it is native to North America - aronia berry lovers claim that the berry is virtually a miracle food that helps reduce the risk of almost every health problem, from colon cancer to hypertension to heart disease, while increasing all the good, buzzing things your body needs, including strengthening the immune system and providing antioxidants.
