Expenses frequently spent to buy chocolates were from 1-3 € per week by young people (18-23 years) and middle age generation of people (46-55 years).

ANALYSIS OF CAROTENOIDS AND LYCOPENE IN TOMATO (LYCOPERSICON ESCULENTUM MILL.) AND THEIR RETENTION IN TOMATO JUICE

800x600 Normal 0 21 false false false SK X-NONE X-NONE In this work we investigated the effect of variety and processing on the content of carotenoids and lycopene in fruits and Tomato juice from the fruit after heat treatment. The experiment included four varieties are edible tomato for industrial processing (Bab, Žiara PK, Sampion and Roti PK). The concentration of total carotenoids and lycopene were determined spectrophotometrically on UV-VIS spectrophotometer Jenway at a wavelength of 445 and 472 nm. The highest average content of carotenoids in fruits were recorded at a variety Roti PK (7.0 mg/100 g -1 ) and lowest in variety Bab (4.8 mg/100 g -1 ). Heat treatment had a statistically significant positive effect on the lycopene content, changes in carotenoid content were not significant. Effect of genotype (variety) for the content of the endpoint was significantly important. doi:10.5219/195 Normal 0 21 false false false SK X-NONE X-NONE

The objective of this paper was the identification and evaluation of the purchase preferences of the Slovak consumers of small fruits and berries. The evaluation of the consumers’ purchase behavior was carried out by methods of mathematical statistics. Data collection for the identification of main preferences in the purchase and consumption of small fruits was conducted by the questionnaire survey. We applied methods of statistical hypotheses testing and finding out dependencies between the determined characters. The existence of a statistically significant relationship was verified by χtest. Calculations were performed by tools of MS Excel, 2013. The statistical hypotheses testing showed that in the process of the purchase of small fruits there is no statistically significant relationship between the gender of respondents and the country of origin of fruits. Similarly, we found out that there is no statistically significant relationship between the respondents age and the country of origin of small fruits.

The Effect of Foreign Language Competences and Student Mobilities on Graduates’ Employability in the European Labour Market

Abstract Foreign language competences belong to the employers’ essential requirements set for workforce. The enhancement of acquired competences and the acquisition of new ones form a part of higher education. In the paper employability of the graduates of the Faculty of Biotechnology and Food Sciences in the Slovak University of Agriculture in Nitra on the European labour market has been analysed. The graduates completed their study in the years 2007-2011. A questionnaire was used to survey 300 graduates by the 30th June 2011, out of which 103 responded. The Faculty of Biotechnology and Food Sciences prepares professionals in the fields of biotechnology, food technology, applied biology, hygiene and food safety. Input data have been evaluated by the methods of analysis, synthesis and comparison. In relation to the mathematical-statistical methods used, the input data have been classified according to the qualitative and statistical characteristics and evaluated by the association tables and graphs. We have come to the conclusion that foreign language competences are actively used by 43% of the respondents in different sectors of national economy, and the dominant foreign language is English. Within half a year after graduation 74% of respondents who had taken part in student mobilities, and 48% of respondents who did not participate in them, found jobs on the labour market. The time of getting the first job is influenced not only by knowledge, working skills and other competencies but also by current job vacancies.

EXAMINATION OF FACTORS INFLUENCING THE VARIABILITY OF YEAST AMOUNT IN THE CONTEXT OF PH CHANGES IN BOTTLED WINES

Aim of this paper was to examine of factors ( manufacturer, temperature and storage time ) influencing the variability of yeast amount and pH changes in bottled white wines. It was confirmed that wine coming f rom the business network was better quality in contract to domestic wine. We have assumed that domestic wine was contaminated during the manufacturing process, while the most probable reason was imperfect filtration of wine, or its contamination during the bottling. The results showed that the way of storage wine in the room , resp. cooler temperature did not significant effect on changes in the amount of yeast (p-hodnota=0.2080). Regarding the period of storage of wine , the conclusions are identical to the previous factor , ie . storage time not significantly impacted amount of yeast in wine ( p - value =0.5507 ). doi:10.5219/151
