Abstract
Nutrients and technological properties were determined in developing Rosa canina L. fruits (rosehips) from Konya (Hadim) and Kastamonu to investigate potential uses. Completely ripe fruits contained ash, crude oil, crude energy, crude fiber, crude protein, ascorbic acid, dimethyl sulfite (DMS), and minerals including K, P, Mg, Ca and Fe. Also, technological properties such as length and width of fruit, weight of 1000 fruits, projected area, porosity, bulk density, hectoliter weight, skin break resistance were measured. In general, dry matter, crude energy, crude protein, ascorbic acid, water-soluble extract, acidity, DMS, Na, K, P, Mn and Mg contents of Kastamonu rosehip fruits were higher than those of Hadim fruits. Ascorbic acid was also present at high concentrations in the rose fruits. Also, length of fruit, width of fruit, weight of 1000 fruits, projected area and fruit bulk of Kastamonu rose fruits were found to be higher than those of Hadim fruits. Results of the static and dynamic coefficients of friction for both rose fruits were found to be similar.
