dc.description.abstractThis analytical study was carried out on some of the common non-carbonated soft drinks manufactured by various food industries in Nigeria. Among those analysed, shelf-life studies of five commonly consumed brands namely Juicy Orange, Apple, Tutti frutti, and Cola all of Saladel Enterprises Ltd., Products, Kano and Lima Orange juice of Lima Services Ltd., Kano, were carried out on storage for three months at room temperature (23° - 25°C). For the shelf life study the following parameters were envisaged; specific gravity values, Brix values, refractive index, pH, Acidity, Ascorbic acid, total solids, crude protein, saccharin, colour and preservative used.like free sulphurdioxide, sodium benzoate and sorbic acid if present. These analysis were carried out on the freshly bottled samples, which served as the control (standard) while the storage samples were analysed periodically after 4, 8, and 12 weeks storage. For the colour determination, analysis was done periodically after two weeks. However, in comparison with the control, results showed a constant increase in pH, total solids and some other parameters with time while ascorbic acid (Vit. C), preservatives and crude protein values, decreased. -vi -Slight changes were recorded in the colour, taste and flavour of the camples on storage. The titratable acidity values remained virtually constant throughout the period of investigation although it varied from one drink to the other. Other parameters studied but not included for the storage study were ash content, alkalinity of ash, moisture content, average liquid content, head space, major and trace elements. Other ready to drink types purchased from the market were also analysed, they were Fruits Orang e made at Ogbomosho in Oyo State, VIP Apple drink from Lagos, Essdee grapefruit from Lagos, Fruit Maid Pineapple from Jos, Caprisonne Orange from Kaduna and Okin pure apple drink also from Kaduna. The last two samples analysed were the concentrated drinks (Dilute to taste types) namely:- Tree Top Orane drink produced by Lever Brothers Limited, Lagos and Rola Extra Strong Lemon-lime by Alro Ltd., Kano. From the data collected, an attempt has been made to: (a) enumerate how the various non-carbonated soft drinks analysed compared to each other; and vii -how they measure up to the stipulated quality standards required of soft drinks in agreement with the food Laws of Nigerian Standard Organisation (N.S.O.), and Food and Drug Administration Standards (F.D.A). (b) detect any adulteration and estimate the contaminants.en_US
