Croatia, located in Southeastern Europe on the Balkan Peninsula, is rich in agricultural resources, especially olives, grapes, and various fruits. In recent years, with the increasing consumer demand for healthy and natural foods, Croatia has witnessed significant growth in the application of natural hydrocolloids. Pectin, citrus fiber, carrageenan, and konjac gum, all natural, plant-based ingredients, are widely used in dairy, beverages, snacks, bakery products, sauces, health foods, and personal care products, playing an important role in driving local industry innovation and upgrading. In the dairy and beverage sectors, pectin is widely used in yogurt, probiotic drinks, fruit juices, and functional beverages. High-ester pectin offers superior stability in acidic environments, effectively extending shelf life while maintaining a refreshing taste and highlighting the natural fruit flavor. Citrus fiber shows significant advantages in low-sugar and high-fiber beverages, enhancing mouthfeel while increasing dietary fiber content, helping consumers meet their daily fiber needs. Carrageenan is widely used in dairy desserts like custards, puddings, and jellies, where it forms stable gel structures to improve texture. Konjac gum, with its transparent and elastic gel properties, has extensive application prospects in low-sugar desserts and plant-based meal replacement drinks, offering healthier and more delicious food options. In snacks and bakery, citrus fiber is widely used to improve dough hydration and gas retention, helping cakes, biscuits, and local pastries stay soft and moist. Pectin, as a natural gelling agent, provides stable structure in jams, candies, and cake fillings, preventing water separation and maintaining gloss. Carrageenan and konjac gum enhance gel strength and texture layers in puddings, mousses, and gummy snacks, offering consumers a richer sensory experience. In sauces and condiments, pectin and citrus fiber improve the stability of sauce systems, preventing separation and enhancing flavor integration. Carrageenan is widely used in meat products, improving sliceability, water retention, and overall texture. Konjac gum is widely used in low-sugar, low-fat, and plant-based sauces, optimizing both texture and mouthfeel. In personal care, konjac gum and citrus fiber are used as natural skincare ingredients in lotions, face masks, shampoos, and conditioners. Konjac gum provides excellent moisturizing effects, keeping the skin hydrated, while citrus fiber offers gentle exfoliation and adsorption properties, effectively cleansing the skin and promoting cell turnover. As consumer demand for natural, plant-based ingredients increases, the food and personal care industries in Croatia are moving toward healthier, more natural products. Pectin, citrus fiber, carrageenan, and konjac gum, as naturally sourced functional ingredients, not only meet market demands but also promote technological progress and innovation in local industries.
