Hydrolyzable tannin analysis in food

Area of Science:

• Food Science
• Analytical Chemistry
• Nutritional Science

Background:

• Plant polyphenols significantly impact food quality (taste, color, stability) and human health by reducing chronic disease risk.
• Hydrolyzable tannins (HTs) were the first plant polyphenols studied analytically, nearly 200 years ago.
• Research on HTs in food analysis is extensive, focusing on extraction, identification, and quantification, despite limited commercial standards.

Purpose of the Study:

• To provide a comprehensive review of analytical chemistry applications for hydrolyzable tannins (HTs) in food.
• To summarize the current tools and methodologies employed in the analysis of HTs within food matrices.

Main Methods:

• Literature review of scientific papers on HTs analysis in food.
• Synthesis of information regarding extraction optimization techniques.
• Compilation of identification and quantification methods used in food analysis.

Main Results:

• A wide array of analytical chemistry applications and tools are utilized for HTs analysis in food.
• Extraction optimization, identification, and quantification are key areas of research focus.
• Challenges related to the lack of commercially available standards persist in HTs analysis.

Conclusions:

• Analytical chemistry plays a crucial role in understanding the presence and impact of HTs in food.
• Continued research and development of analytical tools are necessary for accurate HTs assessment.
• Standardization of analytical methods would enhance the reliability of HTs quantification in food products.
