Local producers constitute a crucial segment of the local economy, playing a pivotal role in driving rural development and the progress of tourism. Their avenues for showcasing products extend beyond markets, bazaars, or food events, often being integrated into a destination’s tourism offerings. Moreover, they contribute to the culinary progress within tourism. Originating from wider rural areas or nearby villages, local producers significantly impact everyday migrations, services, and financial transactions in relationships spanning suburban–urban, village–town, and cross-border cooperation. This study aims to scrutinize the social facets of the organization and work of local producers, offering insights into contemporary market processes. It also serves to illustrate cross-border cooperation and the role of culinary tourism in local business. Through qualitative data processing, we will delve into the outcomes of cross-border projects, emphasizing ethical and sustainable values rooted in territory, landscape, local culture, authenticity, and the application of culinary elements in tourism. The results will shed light on the economic, social, and cultural ramifications on markets in border regions, influencing daily life and the economy. This study will define key aspects of rural development. These research findings can inform local governments, the economy, and communities in future strategic planning for developing this market segment. Tourism, especially in hospitality, will empower rural communities to enhance financial inflow and create local employment opportunities, such as roles for vineyard tour guides or local chefs. Simultaneously, it will bolster other sectors of the local economy, such as agriculture.

The objective of this research was to investigate the potentiality of carrot powder (CP) utilization at levels 4, 6, or 8% as ingredient of corn snacks and evaluation of the extrusion influence on functionally important ingredients such as carotenoids (color), polyphenols, fiber, fat, and antioxidant activity. The influence of ascorbic acid (AA) as an external source at levels 0.5 and 1% on this particular extrusion was also investigated. A single-screw extruder at two temperature regimes (135/170/170 °C (E1) and 100/150/150 °C (E2)) carried out extrusion. The E1 temperature regime acted favorably on total polyphenol content and crude fiber, but fat preferred the E2 regime. Extrusion, especially the E1 temperature regime, increased the extractability of carotenoids. Ascorbic acid degraded during extrusion, but it still provided protection to carotenoids and color attributes of extrudates. Snacks with increased nutritional and functional value due to carrot powder addition were successfully produced, which is a starting point for production of a new type of extruded snacks.

Children with Down syndrome often face significant feeding difficulties and health comorbidities that may contribute to undernutrition or obesity. This study assessed dietary habits and nutritional status among 104 children with Down syndrome in Croatia, representing 11.5% of this population. Results showed that over 30% of children aged 1 to 15 were overweight. Over 60% never consumed whole grain bread, while more than 50% avoided fish, nuts, or seeds. Despite rural families more frequently producing their own food (meat p = 0.009; fruits/vegetables p = 0.035), no significant improvement was observed in the children’s diets compared to their urban counterparts. Urban children consumed milk (p = 0.008) and fermented dairy (p = 0.005) more often. Children of university-educated mothers had higher vegetable (p = 0.031), meat (p = 0.025), olive oil (p = 0.003), and nut (p = 0.029) consumption, and a lower intake of processed meats (p = 0.008) and salty snacks (p = 0.040). Families spending less than 50% of income on food also showed significantly healthier dietary patterns. Feeding difficulties in children with Down syndrome are commonly associated with sensory sensitivities, oral-motor impairments, and comorbid medical conditions. These challenges are often intensified by parental anxiety, delayed introduction of diverse foods, and inadequate professional support. Collectively, these factors contribute to selective eating, poor nutrient intake, and disordered eating behaviors. This study underscores the need for individualized nutritional interventions that address the unique physiological and sensory requirements of both children and adults with Down syndrome. Effective strategies should extend beyond general dietary recommendations to include early exposure to a variety of food textures, specialized feeding support, and the management of coexisting health conditions. Family education and engagement play a crucial role in achieving positive nutritional outcomes. Empowering parents and caregivers—especially those in socioeconomically disadvantaged or rural communities—can facilitate the alignment of food accessibility with healthy dietary practices. The findings of this research offer valuable guidance for the development and implementation of national strategies aimed at enhancing the nutrition and long-term health of individuals with Down syndrome.

In this study, the morphological, pomological, and nutritional values of wild and cultivated rosehip fruits grown in the Slavonia region of eastern Croatia were studied. The results revealed significant differences in several morphological and pomological characteristics among the rosehip genotypes in terms of fruit weight, flesh weight, seed weight, and fruit flesh ratio, with no significant differences in fruit width, fruit length, fruit shape index, seed number per fruit, or seed length. The evaluated rosehip fruit genotypes differed significantly from each other in terms of hectoliter weight (kg), fruit bulk (cm3), and bulk density (kg/m3). For water–soluble extracts, ash, and pH, no statistical difference was found between naturally grown genotypes, but there was a significant difference between naturally grown and cultivated genotypes. Twenty-three major and trace elements were analyzed. The most abundant elements were K, Ca, Mg, and P in both cultivated and naturally grown fruits. The highest concentrations of microelements were Fe, Al, Mn, and Sr. The conventionally cultivated genotype L1 had the highest concentration of Fe and Na as essential elements for humans but also had the highest concentrations of Al, Sr, Ti, V, Cr, Pb, Co, Li, and As of all the genotypes studied. The naturally grown genotype L4 had the highest concentrations of S, Zn, Rb, and Cd and the lowest concentrations of Mg, K, and Ca among all studied genotypes. The data showed that the analyzed genotypes from eastern Croatia had good nutritional quality and variability, making them suitable as genetic resources and possibly leading to the detection of rosehip genotypes as potential sources of beneficial ingredients for human health.
