Due to the growth in production of raspberry ( Rubus sp.) in the Una-Sana Canton, there is a considerable need to research the fruit quality, as well as to guide the production in order to satisfy the requirements of the market. Raspberry fruit is very interesting for consumers because of its pleasant aroma and color, low calories, and high nutrient value, with health benefits that manifest in the high amount of antioxidants. In this paper, we have examined the morphological, chemical, and sensory properties of four cultivars of raspberry (Meeker, Willamette, Fertodi, Polka) grown in the area of the municipality of Bosanska Krupa. The Polka cultivar had the best morphological properties with average fruit width of 1.91 cm, height of 2.31 cm, and weight of 4.80 g. This cultivar also received the best sensory scores. In all the cultivars, there was a high percentage of dry matter (14.05%-16.67%), ash (0.33%-0.59%), reducing sugar (2.3%-4.99%), acid (0.78%-1.95%), and cellulose (0.93%-2.66%), as well as phenols (164.54-416.24 mg GAE/100 g), anthocyanins (53.38-58.83 mg/100 g), and vitamin C (35.77-54.92 mg/100 g). Among the cultivars, Fertodi had the highest share of antioxidant compounds and those differences were significant (P ≥ 0.05). By using principal coordinate analysis the Polka cultivar was characterized by width, height, and mass of fruit; Willamette by anthocyanin and phenols; and Meeker by vitamin C content.

During the war in Bosnia and Herzegovina a large number of chemicals had been released into the environment. This research was conducted to evaluate the health safety of honey (meadow, chestnut, acacia, amphorae and honeydew) produced at 18 different locations in the region of Una-Sana Canton in the northwestern part of Bosnia and Herzegovina. The determination of the pesticides, heavy metals, radioactive elements and antibiotic residues in 46 honey samples were done. The content of pesticides and heavy metals (Pb, Cd, As) were not found and the concentration of Cu, Fe, Zn in all honey samples was in accordance with EU standards. The statistically significant differences (ANOVA) in honey samples were found according to concentration of Cu (0.09 - 0.18 mg/kg), Fe (0.29 - 0.92 mg/kg) and Zn (0.18 - 1.38 mg/kg). The radionuclide content was determined by means of low-level (<5 Bq/kg), using high-resolution gamma-spectroscopy (137Cs). Antibiotics residues were carried out by disc plate method of microbiological antibiotic assay and all honey samples was negative. The results of this work indicate that this area is not polluted and is suitable for development of beekeeping.
