Fix locally sourced citrus fruit (orange citrus sinners) tangerine (citrus reticulate) lemon citrus lemoni) (Lime (citrus aurantifolis) and Grape (citrus paradist) were mixed together to produce mixed fruit drink. Different ratios of orange, tangerine lemon, lime and Grape fruit juice in this order were blended together, sample A 9:5:1:1:1, B5:2:1:1:1: C 4:3:2:2:2: D6:1:1:1:1:1: Quality parameter tested and the result obtained are Vit C A 16.12,B 17. 34, C 24.20, D23.47 and E10.48 mgliooul. Tctoable acidity A 1.04, B1.06 C1.03, D1.08 and E1.O2 kgmlu3. total  solid A12.06,B12.22, C13.14. D14.34 and 16.011. Specific griocty A 1.26, B1.11 C1.12,D1.11 and E1.13. Sensory evduation  test showed that sample A 13 and C are the same at 5 1/1 significant deference. Sample C is greater in total solid. Sample A is the best accepted.  The process is recommended for the production of mixed fruit juice.
