Abstract
In this study, triple strength Zobo concentrate (ZC) was prepared using purple calyx of Sorrel by Hurdle Technology; and asepti-cally packaged in ambered coloured containers for spray drying. The prepared samples of ZC were sweetened with inverted sugar syrup (coded 617) and sodium cyclamate (coded 615) were subjected to sensory, physico-chemical and microbial analyses.The physico-chemical properties of both samples for the pH ranges from 4.1for sample 615 (i.e.ZC sweetened with Sodium cyclamate) and 4.3 for sample 617 (i.e.ZC sweetened with inverted sugar syrup); and the Brix content of the sample coded 615 was 5.8% and 3.8% for the sample coded 617, respectively. And the results of the microbial analysis indicated that both samples are safe for human consumption because both samples microbiological result is ˂1.0x101cfu/ml, which is within microbial limits (103cfu/g) for ready to eat (RTE) foods.The results for the Sensory evaluation conducted for T-test for the two samples 615 and 617 are significantly not different (P
