ABSTRACT

The study investigated the production and evaluation of quality indices of African salad emulsion samples. Palm bunch used for the preparation of the ash solution was obtained from umudikc. Other African salad emulsion ingredients such as Bouillon cubes, salt. crayfish and pepper were obtained from Isochi eke market in Ahia state. The African salad emulsion samples were divided into portions and designated CPO 1, CP02, CP03 and CPO4 Respectively. CPOI and CPO2 emulsion samples were prepared with 90% oil.IO% Ash Filtrate and the same quantities of pepper, salt and• Bouillon cubes without crayfish while CPO3 and CPO4 emulsion samples were prepared with crayfish and other ingredients used for CPO1 and CPO2.Thcse samples were stored on the Shelf for 14days. CPOI and CPO2 were kept open while CPO2 and CPO3 were kept closed. Minerals and Vitamins were evaluated only on Day 0 with standard methods while· Moisture content. lodine value, Free fatty acid, Peroxide value, Saponification value, Thiobarbituric acid value and Refractive index were determined from Day 0 to Day 14 with effective monitory and data collection after every 2 days intervals. The Data generated were subjected to ANOVA (Analysis of variance) of Complete Randomized Design (CRD) using SPSS version 20 while mean separation was done using Duncan Multiple Range Test at 95% confidence level expect for moisture that was graphically represented. The results obtained showed that Calcium ranged from 28:5.43 to 323.20mg/100g, Magnesium ranged from 105.06 to 151.52mg/100g and Potassium Ranged from 154.52 to2 202.66mg/l00g respectively while Vitamin A Ranged. from 50.28 to 53.23g/g, Vitamin C Ranged from 12.10 to 20.90m/100g while Vitamin E Ranged from 13.39 to 16.28mg/l00g.The Iodine value, Peroxide value, Free fatty acid, Saponification value, Thiobarbituric acid value were observed to decrease with increase in storage period. The moisture content also increased with increase in storage period. The study has shown that African salad emulsion samples cannot store for a long time irrespective of the ingredients involved in its preparation.
