This study aimed to determine the nutritional status and dietary habits of younger school age children and to assess the accuracy of parental perception regarding their children’s eating behaviours. A total of 300 children aged 7–11 years from northwestern Bosnia and Herzegovina participated in this cross sectional study. Nutritional status was evaluated using anthropometric measurements and age and sex specific body mass index (BMI) percentile curves. Dietary habits were assessed using an anonymous, adapted, structured questionnaire consisting of 24 questions, incorporating a 24-hour dietary recall and a food frequency questionnaire (FFQ). The questionnaires were independently completed by both children and their parents to assess self-reported dietary intake and eating behaviours. Overall, 60.6% of children were classified as having normal body weight, while 8.7% were underweight, 17.0% were overweight, and 13.7% were obese. According to dietary habits evaluated relative to the USDA MyPlate guidelines (USDA, 2019), 81.3% of children consumed breakfast daily, 69.8% had three meals per day, 52.9% consumed two or more servings of fruit, and 83.7% reported water as their primary beverage. However, 52.9% consumed only one serving of vegetables daily, 51.0% consumed less than 250 mL of milk per day, 69.3% had insufficient meat intake, and 46.7% consumed sweets and snacks daily. Statistically significant differences between children’s and parents’ responses were identified in 79% of the assessed items. These findings indicate a substantial discrepancy between parental perceptions and children’s self-reported dietary intake, emphasizing the need for targeted nutritioneducation programmes for both children and parents to support healthier eating habits.

With the discovery of the main bioactive compounds, royal jelly (RJ) takes a significant role in the food and pharmaceu-tical industry. One of the most important ingredients of RJ is 10-hydroxy-2-decenoic acid (10-HDA). In this paper, ten samples of RJ were analyzed, which were collected from the area of northwestern Bosnia and Herzegovina. In addition to 10-HDA, glucose, fructose, sucrose, and maltose content, physicochemical parameters were analyzed: pH value, total acidity, water content, protein content, and antioxidant activity of RJ. The obtained results show that samples of RJ meet international standards with regard to the content of 10-HDA. Considering the established quality and very high antioxi-dant activity of the analyzed samples (analyzed with DPPH and FRAP methods) they have significant potential in devel-opment of functional products with pronounced nutritional and biological capacity. This work is first attempt in estab-lishment of RJ quality criteria in this area.

Thanks to the climatic and geographical conditions, the area of the Northwestern part of Bosnia and Herzegovina has a long tradition of producing honey and other bee products. However, there is little or no literature data on the physico-chemical properties and biological activity of different types of honey and other bee products from Bosnia and Herzegovina. Five different types of honey were analyzed: monofloral honey (acacia, chestnut, linden), meadow honey and forest honey. Physico-chemical parameters, sensory analysis, color of honey, antioxidant activity, and content of total phenols were analyzed in five types off collected honey samples. The analyzes performed showed that chestnut honey contains the highest and acacia honey has the lowest content oftotal phenolic compounds. The forest honey showed the best antioxidant activity. The color of the honey was measured according to the CIELab system and the estimated L, a, bparameters show that all types of honey from this area can be characterized asdark types of honey (L50) with the presence of a yellow color. The obtained results show that the analyzed samples of five different types of honey are rich in polyphenolic components and represent a good source of antioxidants in the human diet.KEYWORDS:honey,physico-chemical parameters, color, antioxidant activity, total phenols

Alibabić V., Oraščanin M., Vahčić N. (2017): Geographical origin of honey from eight sub-regions of Bosnia and Herzegovina. Czech J. Food Sci., 35: 488–495. Principal component analysis (PCA) and cluster analysis (CA) were used to define the geographical origin of three types of monofloral (chestnut, linden, and acacia), two types of multifloral (meadow and mixed), and forest honey produced over two consecutive harvest seasons in the Una-Sana Canton (Bosnia and Herzegovina), which is geographically divided into eight sub-regions. Statistical analysis was applied to the measurement of physico-chemical and sensory parameters, as well as microand macronutrient (K, Na, Mg, Zn, Fe, Mn, and Al) content, along with some heavy metals (Cd, Pb, and As). Using the PCA method the characteristic parameters for all eight sub-regions were determined, while the CA grouping method was used to determine the characteristic parameters for six sub-regions. Chestnut honey is predominantly found in Cazin, chestnut and linden honey in Bosanska Krupa, chestnut and acacia honey in Bužim, acacia honey in Sanski Most, mixed honey in Velika Kladuša and forest honey in Ključ.

Black chokeberry (Aronia melanocarpa Elliot) is a deciduous fruit shrub from Rosaceae family that does not have a long cultivating tradition in Bosnia and Herzegovina. Therefore, the aim of this research was to determine the effect of variety, quantity and combination of fertilizers on characteristics of vegetative growth, yield and fruit quality of black chokeberry of Nero cultivar, in agro - ecological conditions of the Una – Sana Canton (Bosnia and Herzegovina). The experimental site fertilized with the combination of mineral and organic nitrate fertilizers gave the best results in morphometric characteristics of fruit, yield and vegetative characteristics of growth. Fruits from the control site had the highest values when it comes to the most of the following characteristics: dry matter content, ash, total acidity, vitamin C and total phenolic content. Statistical analyses showed that factors of quantity and the manner of fertilization influence significantly most of examined parameters in this research (P ≤ 0.05).
