COMPARATIVE STUDY ON TURMERIC POWDER COMMERCIALLY AVAILABLE IN DIFFERENT PACKAGING
Present study used different packaging materials of turmeric powder including branded and unbranded available in local market. A pure turmeric rhizome was used as a control and subjected to analysis after grind in fine powder form. In this study, AOAC Official method (1996) was carried out to determine the metal content (Ca, Mg, Fe) and physiochemical parameters (pH, conductivity, total dissolved solid, moisture and ash). The concentration of macro elements (Ca, Mg) were determined by using complexometric titration, while (Fe) was analyzed by spectrophotometically. Results showed that the values of pH, conductivity, total dissolved solid, percentage of ash and moisture were recorded in the range of 5.823-6.760, 516-742µS/cm, 2%, 7.435-9.445%, and 11.450-15.550% respectively, While average concentrations of Ca, Mg and Fe were obtained in the range 176-190 mg/100g, 170-196mg/100g and 38.08-42.57mg/100g respectively. It was observed that metal content are within RDI (Recommended Daily Intake) values. The results were statistically analyzed using analysis of t-test indicate that concentration of Ca,Mg (P < 0.05) there was no significant difference determined among the different sample, however level of Fe (p >0.05) was significant difference in all turmeric samples.
