Tannin fiber and ash content of marketable tea samples packaged in Egyptian factories

ABSTRACT

A survey was performed to analyze the tannein, ash and fiber content of 26 marketable tea samples. The data proved the presence of 4 categories of the tested tea samples with respect to tannein, i.e. 11 to 13%, 14 to 15%, 16 to 17% and from 18 to 19%. The fiber content of the investigated samples showed an average of 9.82-11.5% [DM] for one group and from 11.9-13.98% for the other group. Similar findings were noticed for the ash content; two groups of an average of 5.65% and 7.62%, respectively. Analysis of variance indicated the presence of a significant difference among the tested tea samples
