Suntory is looking for the methods, materials, ingredients or technologies to develop a transparent RTD tea extract that does not discolour during the product’s life.





RTD tea is widely consumed. However, product discoloration over time is one of key issues which impacts consumer satisfaction. This presents a particular quality issue with transparent flavored water products that contain a tea extract.





Key success Criteria
  • Proven or evidenced solutions: basic technology has been tested in a simulated environment.
  • Approaches that comply, or could be developed to comply, with food regulations.




Possible Approaches
  • Removing some of the polyphenols/catechins from tea leaf/extract/infusion without any effect on the beneficial properties of the finished product
  • Antioxidants
  • Packaging or other technologies that positively impact upon the prevention of browning
  • Other approaches that meet the requirements


  • 茶葉。茶抽出液からのポリフェノール・カテキン類の除去
  • 酸化防止剤
  • 褐変防止につながる包材または他の技術
