Microencapsulation of polyphenols is an innovative approach in food technology by which to protect these bioactive compounds from degradation and increase their bioavailability. Polyphenols, naturally occurring in plants, exhibit potent antioxidant, anti-inflammatory and anticancer properties, which make them valuable functional ingredients in foods. However, their susceptibility to external factors, such as light, temperature and pH, presents a significant challenge for their incorporation into food products. Microencapsulation, based on various techniques and carriers such as polysaccharides, proteins and lipids, allows polyphenols to be stabilized and released in a controlled manner in the digestive system. This article reviews the different microencapsulation techniques, carrier properties, and the applications of microencapsulated polyphenols in food products, including bakery, dairy and functional beverages. Additionally, the article discusses the benefits and challenges associated with this technology, highlighting its potential to improve the stability, nutritional value and sensory acceptance of food products.

Computational fluid dynamics (CFD) is a tool for modelling and simulating processes in many industries. It is usually used as a choice to solve problem involving flow of fluids, heat transfer, mass transfer and chemical reaction. Moreover, it has also found application in the optimization of processes in branches of the food industry, including bread baking, cooling beef roast, or spray drying. CFD has enormous potential and many opportunities to improve the quality and safety of food products, as well as to reduce the costs of production and the use of machines and production equipment. In addition, empirical models only permit data to be extracted at a limited number of locations in the system (where sensors and gauges are placed). CFD allows the designer to examine any location in the region of interest, and interpret its performance through a set of thermal and flow parameters. Computer simulations are the future of every field of science, and the presented overview provides the latest information on experts and experiences related to CFD application in food production. Despite some disadvantages, such as the need to have a large reserve of computing power, the development of digital and IT technologies will make this problem insignificant in the nearest future. Then the CFD will become an indispensable element in the design of equipment and technological lines in the food industry.

Electronic noses are devices able to characterize and differentiate the aroma profiles of various food, especially meat and meat products. During recent years e-noses have been widely used in food analysis and proved to provide a fast, simple, non-expensive and non-destructive method of food assessment and quality control. The aim of this study is to summarize the most important features of this analytic tool and to present basic fields and typical areas of e-nose use as well as most commonly used sensor types and patterns for e-nose design. Prospects for the future development of this technique are presented. Methods and research results presented in this manuscript may be a guideline for practical e-nose use.

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.
