Functionalization of Chocolate: Current Trends and Approaches to Health-Oriented Nutrition

Expanding the range of healthy food products is one of the most promising areas in the field of food science. In recent years, there has been an active development of the global trend of functional nutrition aimed at strengthening general health, as well as preventing common non-communicable diseases and metabolic disorders. Chocolate, occupying a leading position among confectionery products, continues to demonstrate a steady growth in consumption on a global scale, which is due to its unique taste and sensory and functional properties. Modern trends in the food industry are aimed at further improving the composition and properties of chocolate, which makes it a promising object for scientific research and innovative developments. This review is devoted to the systematization and study of modern research aimed at developing functional types of chocolate that meet the principles of healthy nutrition. The paper considers the potential of bioactive components, such as polyphenols, probiotics, prebiotic components, dietary fiber, polyunsaturated fatty acids, and plant extracts, for use in the functionalization of chocolate. These compounds have pronounced antioxidant, anti-inflammatory, antimicrobial, and cardioprotective properties. Particular attention is paid to the role of bioactive components of cocoa and chocolate in the prevention of chronic non-communicable diseases, strengthening the cardiovascular system, improving cognitive functions, and normalizing the composition of intestinal microbiota. In addition, promising areas in the field of production technologies and innovative solutions aimed at creating functional types of chocolate with improved consumer properties are considered. The relevance of these developments is due to the growing demand for food products that combine high taste qualities and functionality, which opens up new opportunities for health-oriented nutrition.
