The demand for the products of local origin is becoming more and more important in the world, including in Croatia, whereby the aspiration of consumers to develop the local food sector takes all the great momentum.The contribution to the production of local food in Croatia can provide the Sinj field as one of the largest karst fields with suitable climate and ideal conditions for irrigation, with tremendous potential for agricultural production. The aim of the study was to determine the interest and views of the local population of Sinj and the Cetina region towards the products of the Sinj field and their willingness to pay higher prices for these products by an online survey. The results of the survey research show that almost half of the interviewed occasionally purchase local food from the Sinj field and the surrounding area, and often directly from the producers, and agree that local food supports the development of local farmers. According to the opinion of the respondents, half of them considered that the indication and designation of origin and quality „Products of the Sinj field“ would have a significant impact on their decision to purchase products with that indications and designations and to facilitate the selection and purchase of foodstuffs. The introduction of the „Sinj field Products“ indication would greatly facilitate the purchase of local consumers who are more inclined to purchase local products, either because of the quality of the product or because they want to support local producers by purchasing such products.
