ABSTRACT

The incorporation of bioactive compounds into food products represents a promising approach to enhance their functional and health-promoting properties. However, many bioactive compounds, such as polyphenols, essential oils, carotenoids, and omega-3 fatty acids, are highly sensitive to environmental factors, including temperature, oxygen, and light, which limits their direct application in the food industry. Microencapsulation has emerged as an innovative strategy to overcome these challenges by protecting bioactive compounds, improving their stability, controlling their release, and masking undesirable flavors or odors. This article reviews recent advances in microencapsulation techniques, including spray-drying, freeze-drying, coacervation, and innovative methods such as nanoencapsulation and electrospinning. Particular attention is given to the influence of encapsulated bioactive compounds on the physicochemical characteristics, texture, color, and sensory attributes of various food matrices. Furthermore, the paper highlights industrial perspectives, emphasizing the scalability of these techniques, regulatory considerations, and their role in the development of clean-label, functional, and sustainable food products. The findings underline the potential of microencapsulation as a key technology for the next generation of functional foods, bridging consumer expectations with industrial feasibility.
