The physical properties of fruits and seeds are one of the important parameters in the design of machines and processes for harvesting, handling, storage, grading, conveying, and packaging. European Cranberrybush (Viburnum Opulus L.) is an endemic and organic fruit mostly grown in Turkey, Poland, Lithuania, Russia and Ukraine. It is used as traditional and folk medicine due to the belief that it positively affects human health, particularly kidney stone disease. The high amount of polyphenolics,phenolic acids and anthocyanins, and organic acids bring alternative consumption methods such as fruit juice, nectar, jam, marmalade, pickle, vinegar, and food supplement, tea, granola bar or ingredient of bread, cookie, pudding and cake. In this study, the physical properties of European Cranberrybush fruit and seed were evaluated and compared. The moisture (wet basis) of fruit (86.15%)and seed (56.97%) were determined. The average length, width, thickness, geometric mean diameter,  sphericity, surface area and 1000-unit mass were of fruit 11.33 mm, 9.98 mm, 9.57 mm, 10.23 mm, 1.03, 320.68 mm2 and 647.24 g, respectively. Corresponding values for seed were 7.62 mm, 6.04 mm, 1.82 mm, 4.36 mm, 2.42, 59.94 mm2 and 37.64 g, respectively. The bulk density, true density, porosity, projected area and perimeter of fruit were 544.24 kg/m3, 41.94 kg/m3, 3.33%, 1.15 cm2 and 4.03 cm, while the same value for seed was 340.05 kg/m3, 960.97 kg/m3, 64.44%, 0.45 cm2 and 2.51 cm, respectively. The color values of L*, a*, b*, C and α for fruit (29.88, 30.88, 21.33, 37.53, and 34.64) were found lower than seeds (42.99, 30.90, 32.04, 44.52, and 46.06). In conclusion, the obtained data showed that the European Cranberrybush has one of the smallest fruit and seed in the Caprifoliaceae family.
