2013 International Journal of Biosciences  
An experiment was conducted with three types of essence. Chemical and organoleptical changes in tea quality were evaluated during one-year storage time. The trial was conducted as a Factorial experiment with two factors and three replications. The essences were distributed in four levels including: without essence, cardamom essence, bergamot essence and earl grey essence whereas the period of storage was: 0, 2, 4, 6, 8, 10 and 12 month storage.

The results showed that increase of moisture amount in bergamot tea was further/greater than other ones (6.06%). The Tea without essence has a lower rank of the total color and sensory scores. Thearubigin, TF/TR ratio and sensory scores were significantly decreased with over-time the storage (p≤0.01). The whole essence contents had deceased in all samples after one year storage period.
