ABSTRACT
Blackberries have been used by man for a very long time. There are many species of blackberries, varying in weight and size, including European and American blackberries. Color changes during processing and storage of blackberries have been studied by a number of authors. E. D. Dekazos and G. S. Birth described a light transmittance technique for the nondestructive assessment of degree of ripeness in intact blueberries. J. M. Spiers reviewed the culture of rabbiteye blueberry in the southern US with reference to its agronomic aspects, diseases, harvesting, and market potential of the fruit. Cranberries have also been suggested for use as a source of anthocyanins. The fruit of Rubus spp. is an aggregate fruit consisting of a collection of drupelets, which are small fruits with seeds contained in hard pits surrounded by pulpy flesh. Whortleberries (bilberry, cowberry, bog whortleberry) include several Vaccinium species native to parts of Europe and northern regions of Asia and America.
