dc.description.abstractAnalysis was performed on some tea and coffee samples. Some of the brands of the tea and coffee samples were imported products while the others were processed and packed in Nigeria. The samples were purchased from supermarkets in Zaria. They were analysed for their moisture content, ash content, watersoluble ash content, alkalinity of the soluble ash, tannin content, caffeine content,protein , ether extract and for some inorganic elements which include potassium, phosphorous,magnessium, calcium and copper. The result of the work showed that the tea and coffee samples analysed were of similar qualities with other tea and coffee samples analysed and reported in literature with a few exceptions. The exceptions include moisture content, water-soluble ash and caffeine contents. The moisture contents of a few of the samples were found to be higher than recommended values while their caffeine contents were found to be lower. And, the watersoluble ash of some coffee samples were found to be significantly lower than the literature values. The samples imported were compared with the ones processed and packed in Nigeria for the above constituents. It has been suggested that legal requirements be laid down for the tea and coffee samples processed in the country and also for those imported in. It was further suggested that analysis of more brands of tea and coffee beverages be carried out to have more data about the different samples in the Nigerian market.en_US
