Abstract:

There are many edible fruits and berries which are still underutilized for commercial growing and processing in food products. Some of them known for their medical value (e.g., and Vaccinium vitis-idae, Aronia melanocarpa ) are cultivated in home gardens, but there is little information about nutritional value and suitability of minor fruits for developing products of high nutritional quality. Contents of titrable acids, soluble solids, ascorbic acid, total phenols, anthocyanin, carotenoids, tannins, and antiradical activity (DPPH) of fresh and frozen fruits of saskatoon ( Amelanchier spicata ), Blue honeysuckle ( Lonicera ssp.), golden currant ( Ribes aureum ) Laila, black elder ( Sambucus nigra ), wild rowanberry ( Sorbus aucuparia ), and red bilberry ( Vaccinium vitis-idae ) Coralle has been reported. Saskatoon ( Amelanchier spicata ) is very resistant to low temperatures and biochemical value has been reported to 45-50 mg/100 g total anthocyanin, 18 g carbohydrates, 5.9 g total dietary fibre, 42 mg Ca, 1 mg iron, 3.6 mg C vitamin, 35.7 IU vitamin A. Black Chokeberries have been promoted as a health food, the berries are rich in polyphenol, anthocyanin - the raw juice contains up to 200 mg/100, proanthocyanins, and has demonstrated antiproliferative, and anticarcinogenic effects on human colon cancer. Blue honeysuckle has reported a quite high content of vitamin C (30-103 mg/100 g of fresh fruit), high content of proanthocyanidins (195- 772 mg/100 g), free catechins (122-625 mg/100 g), anthocyanins 116-339 mg/100 g), and total polyphenols (427-1142 mg/100 g). The main value of Black elderberry ( Sambucus nigra ) berries is the high content of anthocyanin (361- 722 mg/100 g) and total phenolics (up to 2240 mg/100 g). Wild rowan trees ( Sorbus aucuparia ) are rich with different bioactive compounds: they contain 15-225 mg/100 g vitamin C, 1.1-19.2 mg/100 g carotenoids, and up to 4300 mg/100 g dry weight total phenolics. Golden currants ( Ribes aureum ) are known as ornamental and rootstock for other currants they contain 40-200 mg/100 g vitamin C and up to 55 mg/100 g carotenoids.
