Abstract

Flavoured teas have a good potential and popularity in the export market. In the present studies, 4 model flavouring compounds, i.e. citronellol, phenylethylalcohol, citral and bergamot oil, were incorporated in black tea and their storage characteristics were studied at 3 temp. conditions, 5 degree C, ambient and 37 degree C, using laminated Al foil, metal can and metallized polyester as packaging materials for a period of 90 days. These were evaluated by instrumental (GC/UV) and sensory methods. Considerable flavour loss was observed in metallized polyester package, at 37 degree C and during the 1st month of storage. The 1st 3 flavoured teas showed a shelf life of 90 days while the bergamot flavoured tea had a shelf life of only 60 days. Highly significant linear correlation was established between the instrumental and sensory values.
