A review on the structure-function relationship aspect of polysaccharides from tea materials

Area of Science:

• Food Science
• Phytochemistry
• Nutraceuticals

Background:

• Tea (Camellia sinensis) possesses a rich history of medicinal applications.
• Key chemical constituents include polyphenols (TPP), proteins, polysaccharides (TPS), and alkaloids.
• Recent research has focused on tea's TPP, with less attention paid to TPS.

Purpose of the Study:

• To review the structure-function relationship of tea polysaccharides (TPS) from tea leaves and flowers.
• To explore the potential applications of purified TPS in functional and nutritional foods.
• To bridge the knowledge gap regarding tea TPS bioactivity and structure.

Main Methods:

• Literature review of recent publications on tea polysaccharides.
• Analysis of studies focusing on the chemical structure of TPS from Camellia sinensis.
• Synthesis of information on the bioactivity and functional properties of tea TPS.

Main Results:

• An increasing number of studies are investigating TPS from tea leaves and flowers.
• The structure-function relationship of tea TPS is an emerging area of research.
• Current applications of purified tea TPS in food products are limited.

Conclusions:

• Tea polysaccharides (TPS) represent a promising area for functional food development.
• Further research is needed to fully elucidate the structure-bioactivity relationship of tea TPS.
• Understanding tea TPS can lead to novel nutraceutical and food applications.
