With the advancement of the modern food industry and the growing awareness of consumer health, the critical importance of food nutrient stability has become increasingly evident. Nutrients in food are highly susceptible to factors such as temperature, light, and oxygen during processing, storage, and digestion, resulting in nutrient loss or diminished functionality. This, in turn, directly impacts the functional activity, value, and absorption efficiency of nutrients. Therefore, conducting research on the stabilization of food nutrients holds significant scientific importance.

This Research Topic aims to bridge the knowledge gap in the design of efficient and safe nutrient encapsulation/delivery systems, enhancing their stability during processing, storage, and digestion. Furthermore, it seeks to clarify the protective mechanisms of these systems in preventing nutrient degradation at the physical, chemical, and molecular levels. Additionally, it aims to assess the release kinetics and bioavailability of nutrients encapsulated within the stabilization systems.

The Research Topic welcome articles addressing, but not limited to, the following themes:
1. Design and Functional Evaluation of Novel Food Nutrient Delivery Systems:
• Precise construction of multi-scale carrier structures (nano/micro)
• Safety and Toxicological evaluation of Carrier-Nutrient Composite Systems
• Controllable construction of pH/enzyme/temperature multi-stimulus responsive mechanisms
• Stabilized protection of environment-sensitive nutrients (e.g., vitamins, polyphenols)
2. Stabilization Mechanisms of Nutrient Delivery Systems
• Carrier-Nutrient Interaction Analysis
• Impact of thermodynamic/mechanical forces (thermal treatment, high-pressure homogenization) on delivery system structural integrity
• Construction of degradation models under light, oxidation, moisture, and heat conditions.
3. Bioavailability Enhancement Strategies for Nutrients
• Stability and Release Characteristics During Gastrointestinal Digestion
• Regulation of mucus layer permeability and intestinal epithelial cell transport
• Modulating nutrient release through gut microbiota-carrier interactions
• Standardization and validation of in vitro dynamic digestion models
