Development of a functional sea buckthorn-based drink with a sugar substitute and collagen

Functional drinks exhibit antioxidant activity due to their content of vitamins, flavonoids, and polyphenols. The developed drink, based on sea buckthorn, apple, and grape juices, contains vitamin C (35 mg/100 mL), beta-carotene, and resveratrol, contributing to its antioxidant and immunostimulating properties. The formulation includes natural, freshly squeezed juices: sea buckthorn ("Altai"), apple ("Voskhod"), and grape ("Isabella"), along with collagen (8.5 g) and stevia (0.3 g). The optimal juice ratio (apple 60%, sea buckthorn 20%, grape 20%) ensures a balanced taste and enhanced functional value. The drink exhibits a golden-orange color, a sweet and sour taste, and a fruity aroma. Collagen enhances its biological value, while stevia lowers the calorie content without affecting the glycemic index. Research findings confirm that this combination results in a functional beverage with antioxidant properties, desirable organoleptic characteristics, and reduced calorie content, promoting overall health. Additionally, the drink provides essential nutrients that support metabolic processes and overall well-being. Regular consumption of this beverage may help strengthen the immune system and improve skin health due to its rich composition. Moreover, the combination of bioactive compounds contributes to better digestion, energy metabolism, and overall vitality.
