Gastronomy, as a part of cultural heritage, has exceptional potential in tourism, and its key representatives and conservationists/guardians are hospitality facilities that provide food services. Vojvodina (the Republic of Serbia) is a region inhabited by more than 30 ethnic minorities that have nurtured their cultural heritage and have been incorporating it into gastronomy for many years. The subject of this paper is the gastronomy of ethnic groups in Vojvodina and its significance for tourism development from the point of view of hospitality workers as important actors in the sustainability of heritage. One of the motives behind this study is the twelfth UN sustainable development goal (SDGs) defined in 2015, which refers to providing sustainable forms of consumption and production and which emphasizes the development and application of tools for monitoring the impact that sustainable development has on tourism that promotes local culture and products (12b). The aim of this study was to obtain data on the preservation of heritage, that is, on authenticity within the region/area and ethnic groups, and then to perform a valorization of dishes and define steps on how to make gastronomic heritage a more visible tourist attraction, from the perspective of sustainability. Our survey included a sample of 508 respondents, all employees in the hospitality industry. The obtained results were statistically processed. The research showed that the Južnabačka district has the greatest importance in tourism from the aspect of the implementation, preservation, and sustainability of gastronomic heritage in tourism. Among the ethnic groups, the Vojvodina Hungarians place the greatest importance on the preservation of gastronomy, which includes dishes such as goulash and uses ingredients such as river fish. The research led to the conclusion that those in the hospitality industry are of the opinion that gastronomic heritage should be promoted through activities such as tourist exposure, marketing activities, and promoting the diversity of authentic food offers in catering facilities.

Agritourism as a special type of tourist migration is a very important link in the diversification of rural areas, connecting the geography, culture, tradition, and gastronomy of the local population, and placing products and services through the hospitality and tourism market. Thanks to this form of tourism, underdeveloped places are gaining in importance and attracting the attention of visitors who are oriented towards natural things, which in turn contributes to a better economic situation of the locality and the population. This paper aims to examine the attitudes of farm owners in the Republic of Serbia toward the impact of agritourism on the economy, living environment, social life, and culture. The data were collected by surveying the owners of agricultural holdings in the territory of the Republic of Serbia and statistically processed using factor analysis, descriptive statistics, and linear regression. Based on the obtained results, it has been established that the owners of agricultural farms are interested in the development of agritourism, and that their positive perception of the impact that agritourism has on the living environment and economy greatly contributes to that. To a lesser extent, a positive attitude was noted toward the importance of agrotourism for the local community and locals, where the positive aspects of agritourism were the education of visitors on agriculture, promotion of the local culture, agricultural and gastronomic products, and sustainable development and investment in infrastructure.

The aim of the present study was to evaluate the safety parameters, nutritional value and sensory profile of the meat from spiny-cheek crayfish (Faxonius limosus), captured from the Danube River in Serbia. To achieve this, we determined their microbiological safety, chemical composition, minerals and heavy metals, fatty acid and amino acid profile, as well as a sensory profile of the meat. The obtained results showed that the meat from crayfish was microbiologically safe. Crayfish meat has a high nutritional quality, high protein content (18.12%) and a total of 17 detected amino acids, of which essential amino acids constituted 6.96 g/100 g sample. Additionally, the crayfish meat was characterized by high levels of essential polyunsaturated fatty acids (PUFA), particularly n-3 PUFA, at an optimal ratio of n-3/n-6 and with low values of atherogenic and thrombogenic indices. Predominant macrominerals in the meat are K, followed by Na, Ca, P and Mg, whereas the content of microminerals was in the following order: Zn > Cu > Fe > Mn. The concentrations of accumulated toxic metals (Cd, Pb, As and Hg) did not exceed the maximum allowed levels. Sensory analysis confirmed that the meat from spiny-cheek crayfish has the potential to become a new food source of essential nutrients.

The Autonomous Province of Vojvodina represents a region characterized by expressed multi-ethnicity. This unique mixture of more than 30 different nations influenced the formation of a unique and recognizable cultural heritage. Gastronomy, as one of the most impressive components of cultural heritage, has a very important role in positioning a tourist destination on the global market. The subject of this paper is the views of hospitality workers of gastronomic heritage in Vojvodina and its possibilities to influence further development of tourism in the region. This paper aims to provide a better insight into the mindset of hospitality workers, as carriers of the hospitality offer, about the chances of multiculturalism in the region to become a differential force in the tourism market. The research included 508 respondents employed in all hospitality sectors. The results show that the respondents believe that ethnic minorities' dishes are insufficiently represented in offers of hospitality facilities, but that employees believe that they can be an advantage in creation a gastronomic heritage.

Background/Objectives: The presented study aimed to understand the relationship between knowledge, attitudes, and practices, as well as consumers’ preferences for the consumption of Spirulina-enriched fruit and vegetable juices. Methods: A survey about the consumers’ attitudes towards consumption of algae in general and especially Spirulina was conducted to better understand the target groups and marketing strategies for this novel non-alcoholic beverage product. Knowledge–Attitude–Practice (KAP) model in combination with structural equation modelling (SEM) was applied to test the hypothesised relationships between the variables. Additionally, consumers’ preference test was done using a seven-point hedonic scale and ranking of the six juice samples: plain sour cherry juice (SC1), sour cherry juice with 0.8% (SC2) and 1.6% (SC3) of blue Spirulina powder; plain tomato juice (T1), tomato juice with 0.8% (T2) and 1.6% (T3) of blue Spirulina powder. Results: The SEM results showed that there is a limited direct impact of knowledge on social motivation, while personal behaviour strongly predicts social motivation. Namely, perceived nutritional value and health benefits were shown to be the main factors for consumers’ willingness to drink Spirulina-enriched juice. Conclusions: The result of the consumer preference evaluation exposed that the juices containing sour cherry and Spirulina achieved better sensory acceptance and ranking than those containing tomato, pointing out the importance of the product matrix for achieving consumer acceptance.

Spirulina (Arthrospira platensis) is a protein- and antioxidant-rich microalga, but its use in beverages is limited by sensory acceptance. Four juices (apple, sour cherry, tomato, and celery) were initially tested with added blue and green spirulina (0.8% and 1.6% w/w). Based on preliminary acceptability scores, only sour cherry and tomato juices were selected for further analyses. Blue spirulina enrichment increased protein (from 0.80 to 1.36 g/100 g in sour cherry; 0.89 to 1.52 g/100 g in tomato), fat (0.05 to 0.21 g/100 g; 0.09 to 0.25 g/100 g), and energy (259 to 279 kJ/100 g; 140 to 170 kJ/100 g). Antioxidant activity improved significantly, with DPPH IC₅₀ reduced from 260 to 135 mg/mL (sour cherry) and from 268 to 171 mg/mL (tomato). Colour analysis confirmed a shift from red to blue hues (a* from 15.2 to 3.7 in sour cherry). Data were statistically processed using ANOVA followed by Tukey’s HSD test, while sensory data were additionally evaluated by PCA and GPA to identify product-specific differences. These results confirm that spirulina-enriched sour cherry and tomato juices are nutritionally enhanced functional beverages, though sensory off-notes remain a challenge for consumer acceptance.
