A COMPARATIVE STUDY ON ANTIOXIDANT CONCENTRATION IN ORTHODOX AND CTC TEA CAMELLIA SINENSIS L
Siddhartha Sharma* and P. K. Borua
It is now well established that tea has antioxidant properties. In the present study the antioxidant concentrations of two common types of teas, viz. Orthodox and CTC (Crush Tear Curl) were compared. The comparison was done with teas manufactured from two different clones. Samples were collected from six Estates of Upper Assam, where homogenous areas of plantations of the two clones TA-17 (Tinali 17/1/54) & S3A/3 were available. The samples were from the commercially manufactured product with special segregation of the clones to maintain the homogeneity during manufacture. Antioxidant activity measured the highest in the Orthodox teas as compared to the CTC teas in both the clones. The results analysed on one way ANNOVA test also corroborated this (p<0.05) finding.
Keywords: Polyphenol; antioxidant activity; antioxidant concentration, CTC, clones, DPPH Assay.
