ABSTRACT:
Many phenol compoundspresentin the green tea havea wide range of biological effects whichimprovesmany health issues due to its Antioxidant property. Our objectives are to conduct the comparative studies among some leading brands of green tea by ISO 14502 procedures to check the quality of the green tea.And the differences in polyphenol Content and Antioxidant Potentialfollowed byspecified preparation method in product package for the consumers.As per ISO 14502 procedure guidelines to tea manufacturers QC passing it should not less than 20gm/100gm Gallic acid Equivalent, the results showed that TETLEY brand contains GAE 21.9±1.48 gm/100gm, in case of LIPTON brand contains GAE 28.3±1.22gm/100gm and AVT brand contains GAE 17.67 ±0.12 gm/100gm it seems only LIPTON brand passed the QC.But in product package specified preparation methodthe results showed that TETLEY brand contains GAE 0.266±0.035gm/d L and QE 0.388±0.049gm/d L, LIPTON brand contains GAE 0.094±0.01gm. /d L and QE 0.107±0.008gm/d Land AVT brand contains GAE 0.221±0.002gm/d L and QE 0.296±0.021gm/d L seems 65% to 75% content is less in case of LIPTON.Invitro antioxidant activity studies revealed that, one teaspoon (2.961g.approx) of TETLEY brand, one teaspoon (2.682g.approx) AVT brandand halfa teaspoon (1.623g. approx.) suggested by LIPTONbrand possessedthe IC 50 values 1.62, 1.55 and 2.5respectively, if the IC50 value is lesser which indicates more the antioxidant capacity .The obtained results indicates that half a teaspoon of Lipton possess lesser antioxidant potential when compared to other brands. So considering from the results we may conclude that consumers can prepare the green tea as per their requirements not to stick on product specified method of preparation. In future this study can be extended to know the ground reality with subjective to human consumptions to know the actual amount of content is required to get maximum benefits for antioxidants potentiality.
