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.

In this review, the application of computational fluid dynamics (CFD) simulations in analyzing thermal processes within food technology is explored. The focus is on understanding heat transfer, fluid flow, and temperature distribution during various food processing methods, such as baking, frying, pasteurization, and cooling. Detailed insights that are often challenging to obtain through experimental methods alone are provided by CFD simulations, allowing for the optimization of process parameters to enhance product quality and safety. It is demonstrated that CFD can effectively model complex thermal phenomena, providing valuable data on temperature gradients and flow patterns. These simulations assist in the designing of more efficient processing equipment, improving energy consumption, and ensuring uniform heat treatment, which is crucial for maintaining the nutritional and sensory attributes of food products. Furthermore, the integration of CFD in the food industry leads to significant advancements in product development, reducing the time and cost associated with experimental trials. Future research should focus on refining these models for greater accuracy and exploring their application in emerging food processing technologies.

Mechanical processes such as mixing, extrusion, and drying are key operations in food engineering, with a significant impact on product quality and process efficiency. The increasing complexity of food materials—due to non-Newtonian properties, multiphase structures, and thermal–mechanical interactions—requires advanced modeling approaches for process analysis and optimization. Computational Fluid Dynamics (CFD) has become a vital tool in this context. This review presents recent progress in the use of CFD for simulating key mechanical operations in food processing. Applications include the analysis of fluid flow, heat and mass transfer, and mechanical stresses, supporting improvements in mixing uniformity, energy efficiency during drying, and optimization of extrusion components (e.g., shaping dies). The potential for integrating CFD with complementary models for system-wide optimization is also discussed, including challenges related to scale-up and product consistency. Current limitations are outlined, and future research directions are proposed.
