    摘要： The present invention comprises a liquid tea mix concentrate. The liquid tea mix concentrate is shelf-stable and substantially free of sulfur. It is characterized by a low pH, low water activity, high total solids, reduced levels of theaf- lavin and thearubigin, and a polyphenolic profile and molecular weight distribution distinct from other liquid tea mix concentrates. Tea beverage prepared from the concentrate is storage-stable in flavor and clarity. Acid-catalyzed degradation reactions that normally occur between tea mix components causing the development of off- flavor and malodorous sulfurous compounds and precipitates are accelerated during processing. By removing the resultant compounds, the development of off-flavors, off-aromas, and precipitates in the liquid tea concentrate is prevented without the use of preservatives.
