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).

Nepravilna prehrana u najranijoj dobi faktor je utjecaja na moguću pojavu pretilosti, dijabetesa, ateroskleroze ili bolesti kardiovaskularnog sistema u kasnijoj dobi života. Kako su ova oboljenja postala najveći zdravstveni problem svijeta, a sve su zastupljenija kod mlađih uzrasta, vrlo je važno pratiti stanje uhranjenosti kroz razdoblja intenzivnog rasta i razvoja djece. U tu svrhu koriste se antropometrijske metode koje su pored sagledavanja stanja i prikladnosti procesa rasta i razvoja, važne za procjenu rizika za zdravlje u kasnijoj dobi života. Cilj ovoga rada bio je mjerenjem tjelesne mase (TM) i tjelesne visine (TV) te izračunavanjem indeksa mase tijela (ITM) te percentila indeksa tjelesne mase (%ITM) procijeniti stanje uhranjenosti djece predškolskog uzrasta koja pohađaju vrtiće u općinama Unsko sanskog kantona (USK-a) (Bosna i Hercegovina), kroz 2 godine istraživanja (2014. i 2015.). Istraživanje je obuhvatilo 356 djece u dobi od 2 do 6 godina, od toga 55,4 % dječaka 44,6 % djevojčica. Djevojčice su prosječno rasle nešto više (5,25 cm/god.) u odnosu na dječake (4,0 cm/god.), ali rast nije bio praćen odgovarajućim povećanjem tjelesne mase koji je godišnje prosječno iznosio 2,1 kg za djevojčice i 1,9 kg za dječake i u oba slučaja niži je u odnosu na normalni rast i razvoj. To je rezultiralo visokim udjelom djece u kategorijama pothranjenih ili rizika od pothranjenosti (21,5 %) i zabrinjavajuće niskim udjelom normalno uhranjene djece (45,7 %). Prekomjerno uhranjene i pretile djece bilo je 32,6 % što je niži udio u usporedbi sa zemljama u okruženju, međutim visok je i obavezuje na potrebu stalnog praćenja stanja uhranjenosti i uvođenje preventivnih programa edukacije u predškolski sistem.

Abstract The iron deficiency anemia is particularly common in reproductive age women. Thus, it is important to explore facts of knowledge about importance of iron in nutrition in female population. The study included 176 respondents and collection of data was done using a questionnaire and statistically analyzed. Women from rural area, women in younger age groups and pregnant women showed a higher level of knowledge about importance of iron in nutrition. The most respondents were in the normal weight range, but the significant prevalence of inadequate iron intakes was determined (daily average intake for iron was 7.62 mg/day) and there was significant difference between groups. Also, respondents had no knowledge concerning factors affecting iron supply from their diet, while it seems justified to focus our attention on these problems within the framework of educational activities.

Abstract Nutritional risk factors can have a significant impact on mental and physical health of the student population. The aim of this study was to assess the nutritional status and quality of diet given to the recommended (RDA) input of nutrients, and to determine the eating habits of the student population of the University of Bihac (Bosnia and Herzegovina). The survey included 428 respondents (60.98% F and 39, 02% M) with an average age between 19 and 23 years. The research results indicate that students can be categorized as normal weight (97.60% of them), while female students (31.03% of them) fall into the category of moderately lean. Both sexes, with regard to daily energy share, take more fat in their diet (29.49 M and 28.50% F) compared to the RDA recommendations. Breakfast is a regular meal of more than half of the students (67.4%), 94.96% of the student body has lunch regularly, and 80.96% of students have their dinner. The most common diet is the “fast food”. Meat and meat preparations are daily consumed by 54.67% of the student body. Fresh fruits were part of daily diet of 34.2%, and fresh vegetables 31.14% of the student body. Milk and dairy products were consumed among 26.30% of the students. The proportion of students who smoke, and those who consume alcohol is too high.
