Abstract

On cooling, tea infusions become turbid and brown particles settle out forming a `cream' which affects the clarity and appearance of cold-water-soluble tea beverages and consequently has to be eliminated. This article reports the isolation and identification (TLC, column chromatography, GC and GC-MS) of a lipid complex (comprised of components including 1-triacontanol, alpha-spinasterol, and dihydro-alpha-spinasterol) from tea cream. Hydrophobic interactions between lipid complexes and other components of tea cream (including caffeine, tea polyphenols and their gallates, and proteins) and their importance in tea cream formation are described and discussed.
