Food Processing Technologies to Develop Functional Foods With Enriched Bioactive Phenolic Compounds in Cereals

Area of Science:

• Food Science
• Nutritional Biochemistry
• Agricultural Science

Background:

• Cereal grains are a global calorie source, with health benefits linked to phenolic compounds.
• Post-harvest processing and cooking can significantly alter phenolic content and antioxidant activity.
• Systematic exploration of cereal phenolics and their health impacts is limited.

Purpose of the Study:

• To review methods for retaining and enhancing phenolic content in cereals.
• To explore techniques for developing phenolic-rich functional foods.
• To evaluate technologies improving phenolic bioavailability and bio-accessibility.

Main Methods:

• Review of bioprocesses: germination, enzymatic treatments, fermentation.
• Analysis of physical processes: extrusion, nixtamalization, parboiling.
• Evaluation of advanced technologies: ultrasound, micro/nano-encapsulation, infrared processing.

Main Results:

• Bioprocesses like germination and fermentation can enhance cereal phenolics.
• Physical methods such as extrusion and parboiling improve phenolic bioavailability.
• Novel technologies show promise for increasing phenolic content and bio-accessibility.

Conclusions:

• Various processing methods can be employed to maximize phenolic content in cereals.
• Developing functional foods with enhanced phenolic profiles is achievable.
• Further research into optimizing these methods is warranted for health benefits.
