The study determined the effect of addition of hydrocolloids to tomato-carrot juice blend. It also determined some physico-chemical parameters and evaluated the proximate and microbial analyses of the blend. This was with a view to provide information on the properties of tomato-carrot juice blend which gives the most acceptable quality. Two samples of tomato-carrot juice blend were prepared, with one containing hydrocolloids while the other was without hydrocolloids. The products were bottled, pasteurized, cooled and stored at ambient (29 ± 1°C) and refrigeration (5 ± 1°C) temperatures. There was a significant difference in some of the physico-chemical properties (t=2.93, p < 0.05) and sensory evaluation (t = 3.20, p < 0.05) was done between the blend with and without hydrocolloid. The blend with hydrocolloids had better retention of juice quality parameters.
