Food Bioactive Compounds and Emerging Techniques for Their Extraction: Polyphenols as a Case Study.

Area of Science:

• Nutritional Science
• Biochemistry
• Food Chemistry

Background:

• Food bioactive compounds (FBCs) demonstrate significant health benefits, protecting against non-communicable diseases (NCDs) like cancer, cardiovascular diseases (CVDs), and neurodegenerative disorders (NDDs).
• These health effects are attributed to FBCs' antioxidant, anti-inflammatory, and cardioprotective properties, with polyphenols being a key class.
• Polyphenols, abundant in plant foods, show promise as preventive agents against NCDs with fewer side effects.

Purpose of the Study:

• To provide comprehensive insights into the potential of polyphenols in preventing NCDs.
• To review polyphenol classification, biosynthesis, and their preventive effects on cancer, CVDs, and NDDs.
• To explore polyphenol bioavailability, bioaccessibility, industrial applications, and advanced analytical techniques.

Main Methods:

• Literature review focusing on experimental studies and scientific evidence.
• Analysis of chemical structures, biosynthesis pathways, and biological activities of polyphenols.
• Examination of extraction and analytical techniques for FBC characterization.

Main Results:

• Polyphenols exhibit diverse biological activities, including antioxidant, anti-inflammatory, and cardioprotective effects.
• Evidence supports the role of polyphenols in the prevention of major NCDs.
• Challenges in polyphenol bioavailability and bioaccessibility are significant areas for further research.

Conclusions:

• Polyphenols are potent FBCs with significant potential for NCD prevention.
• Further research into optimizing polyphenol bioavailability and applications is warranted.
• Advanced analytical methods are crucial for understanding and utilizing FBCs effectively.
