Abstract


In this study, the chemical and technological properties of blackthorn (Prunus spinosa) and rose hip (Rosa canina) fruits growing wild in Cluj-Napoca area were analysed. Proximate analysis such as dry matter, moisture content, crude protein, crude fiber, ash, water-soluble, pH and mineral contents were established in this work. Al, B, Ca, K, Mg, Na, P and S were determined as major minerals. Mineral content of samples growing in Cluj-Napoca area were determined by inductively coupled plasma ICP-OES. All samples contained high amounts of K (18711-952 mg/kg), Ca (1504.22-88.06 mg/kg), Mg (972-22.7 mg/kg), P (1511-2104 mg/kg), Na (534-34.8 mg/kg), Al (26.3-1.15 mg/kg) and Fe (16.0-1.97 mg/kg). Technological properties such as projected area, porosity, bulk density, and hectoliter weight were measured. The obtained results revealed nutritional properties and mineral contents of analyzed fruit. It is very important to know the technological properties of the fruits because optimal equipment and working parameters can be used for harvesting, transportation and processing.
