Engineered Food Matrix: Precision Processing Strategies to Enhance Bioavailability of Bioactive Phytochemicals

Area of Science:

• Food Science
• Nutritional Biochemistry
• Food Processing Technologies

Background:

• Bioactive phytochemicals (BPs) provide health benefits but have low bioavailability due to food matrix entrapment.
• Traditional processing methods can damage BPs or require costly encapsulation.
• A novel 'engineered food matrix' approach aims to improve BP release and absorption.

Purpose of the Study:

• To critically evaluate the engineered food matrix concept for enhancing BP bioavailability.
• To synthesize knowledge on BPs-food matrix interactions and nonthermal processing technologies.
• To provide guidance for developing functional foods with optimized BP delivery.

Main Methods:

• Systematic review of literature on BPs-food matrix interactions.
• Assessment of precision nonthermal processing technologies (HHP, PEF, ultrasound, enzymes).
• Evaluation of strategies to selectively modify food matrix structures for improved BP release.

Main Results:

• Precision nonthermal processing significantly enhances BP bioavailability compared to traditional methods.
• Engineered food matrices can weaken absorption barriers while preserving BPs.
• Evidence supports improved bioavailability through targeted matrix modification.

Conclusions:

• Engineered food matrices represent a targeted strategy to overcome BP bioavailability limitations.
• Precision nonthermal processing is effective in enhancing BP delivery in food systems.
• Further research is needed to scale these technologies and validate them across diverse food applications.
