Abstract

A laboratory study was conducted to determine the nutritional composition of the various tea brands that were imported into Erbil city. The tea samples included 12 most popular tea brands purchased in various local market and tea shopping with five replications. The design of experimental based on a CRD. The results were indicated that the concentration of (P, N, K and Ca%) in all tea samples were ranged between (0.0350-0.1288, 1.0127-5.8086, 0.0028-0.0275 and 0.1306-0.8891) respectively. The concentration of Mn in tea brands were ranged between (0.0075-0.0325%), the higher concentration recorded in brand2. The loading rotation with Principal axis factoring was conducted to assess the underlying structure for the thirteen variables on the quality and quantity of tea brands. Two factors were selected, based on the validity that the variables were designed to index two constructs quality and quantity. The result of factor analysis revealed that the first factor responsible on 23.38% of the variance, the second factor accounted for 15.56% of the variance. The recorded eigenvalues were 3.040 and 2.035 for F₁ and F₂respectively.
