    Comparison of the Bacterial Inactivation Efficiency ofWater Activated by a Plasma Jet Source and a Pin-to-Pin Electrode Configuration Source
    (MDPI, 2023) Čobanović, Radovan; Maletić, Dejan; Kocić-Tanackov, Sunčica; Čabarkapa, Ivana; Kokić, Bojana; Kojić, Predrag; Milošević, Slobodan; Stulić, Višnja; Vukušić Pavičić, Tomislava; Vukić, Milan
    In this comparative study, the bacterial inactivation efficiency of plasma-activated water (PAW) generated by two distinct plasma reactors, one utilizing a nitrogen plasma jet electrode and the other a hybrid argon plasma reactor, was explored. The present study involved the assessment of antimicrobial activity against suspensions of three Gram-positive and three Gram-negative bacterial strains in their planktonic cell state. Bacterial suspensions were introduced into PAW five days after generation. Subsequently, the viability of the bacteria was assessed at various time intervals, specifically at 0.5, 1, 3, 5, 10, and 24 h, in order to evaluate the effect of inactivation. Structural changes in bacteria after PAW treatment were assessed using a scanning electron microscope (SEM). The physicochemical properties of PAW, including pH, conductivity, and concentrations of H2O2, NO2 -, and NO3 - during aging were measured. The present study demonstrated the effective inactivation of the tested bacterial strains by PAW. Gram-positive bacteria displayed greater resistance compared to Gram-negative species, with the lowest reductions in bacterial counts observed for B. cereus, and the highest for Escherichia coli O157:H7. Morphological damage was evident across all bacterial species examined. Physicochemical measurements showed slow decay of the reactive species in the aging process. This study illustrated the potential utility of PAW as an alternative disinfectant.

    Consumer Attitudes and Preferences towards Traditional Food Products in Vojvodina
    (MDPI, 2023) Peulić, Tatjana; Marić, Aleksandar; Maravić, Nikola; Novaković, Aleksandra; Kalenjuk Pivarski, Bojana; Čabarkapa, Ivana; Lazarević, Jasmina; Šmugović, Stefan; Ikonić, Predrag
    The objective of this study was to identify consumers’ attitudes about the consumption and certification of traditional food products, special characteristics to which they pay attention when buying food products, and their opinions regarding what traditional food products are to them. The research was based on an online questionnaire conducted on a sample of 540 respondents in the Autonomous Province of Vojvodina. The results showed that 98.3% of the respondents consume traditional food products in their households, 95.2% of the consumers decide to buy food products based on their quality, and 68.2% of the consumers believe that certain types of certification can improve product placement on the market. The specific characteristics that consumers mostly prioritize when buying food products are products with no added sugar (41.2%), traditional production processes (38.8%), GMO-free products (36.9%), organic products (36.4%), and additive-free products (34.9%). The results of this research indicate that consumers primarily perceive traditional food products as items produced using traditional methods (72.8%), characterized by the absence of additives (53.2%), specific to a certain geographic area (49.9%), sourced from small farms or facilities (49.5%), and products with long production tradition (49%).

    Traditional food products on the local market - consumption conditional on the characteristics of management and restaurant facilities in tourism of Vojvodina (Serbia)
    (Frontiers Media SA, 2023) Kalenjuk Pivarski, Bojana; Tekić, Dragana; Šmugović, Stefan; Novaković, Aleksandra; Ivanović, Velibor; Petrović, Marica; Banjac, Maja; Đerčan, Bojan; Tešanović, Dragan; Ćirić, Miloš; Čabarkapa, Ivana; Ćirić, Ivana; Šarac, Veljko; Maravić, Nikola
    The research dealt with traditional food products (TFP) observed on the local hospitality-touristic market, from the point of view of 300 restaurant workers employed in managerial positions, as important subjects in preservation of tradition in hospitality and touristic industry of Vojvodina (Republic of Serbia). The research examined the management’s views on TFP, as well as whether there are differences based on the features of the respondents as well as the restaurant facility. In order to obtain data that would provide additional guidelines for acting on the hospitality and tourism market, the procurement and consumption of TFP was also examined. In order to determine set differences the non-parametric Kruskal-Wallis test was applied. In order to establish statistically significant differences between the observed groups, the Dunn’s post hoc test was applied. In the second part of the research, a binary logistic regression model was applied in order to determine which of the observed variables has a significant impact on the respondents’ decision to acquire TFP from their field. The research showed that the level of education and the field of management education significantly influence the attitudes about the offer of TFP in the hospitality and tourism market, as well as the type of restaurant offer and the development of the field of business.
