Some nutritional and technological properties of garlic (Allium sativum L.)

The nutrients and physical properties were measured in developing Allium sativum L. bulbs from Kastamonu (Taşköprü) to investigate potential uses. Completely ripe bulbs contained crude protein, crude oil, crude energy, crude fiber, ash, dimethyl sulphite (DMS) and essential oil and minerals including K, P, Mg, Na, Ca, Fe, etc. Crude protein, DMS and essential oil contents were determined as 17.2%, 1779 μcg/kg and 0.14%, respectively. In addition, K (21,378.84 mg/kg), P (6009.37 mg/kg), Mg (1056.15 mg/kg), Na (532.78 ppm) and Ca (363.61 ppm) were reported such as the major minerals in garlic bulbs. Also, technological properties such as diameter of whole garlic, mass, segment number of whole garlic, length of whole garlic, width, thickness, geometric mean diameter, sphericity, projected area, volume, bulk density, segment density, porosity, terminal velocity and hardness were established. The mean mass, mass weight of 1000 garlic segment, length of segment, diameter of whole garlic, geometric mean diameter, sphericity, projected area, volume, bulk density, porosity and hardness of segments were measured as 32.81 g, 2383.8 g, 27.24 mm, 46.51 mm, 15.15 mm, 0.559, 4.54 cm2, 2245.64 mm3, 478.75 kg/m3, 54.16% and 13.78 N, respectively. Also, static and dynamic coefficient of friction for garlic segments were established on a galvanized sheet, an iron sheet and plywood. These values for static and dynamic coefficient were found as 0.416-0.352; 0.472-0.406 and 0.541-0.481, respectively. The physical properties of equipment used must be know for planting, harvesting, transportation, storage and other processing.
