Study the concentrations of Cd, Pb, Ni, Zn and microbial quality in some kinds of candy

Abstract

Twenty samples of candy sweet were related to Turkish and china's companies collected from local Iraqi markets to measure the concent-rations of some heavy metals (Cd, Pb , Ni and Zn) , also evaluate the microbial quality includes: bacteria and fungi in these tested products.
The results revealed that most of studied samples do not exceed the acceptable values were proposed from both WHO and Iraqi standards except the samples N and T. The same results were recorded for Pb concentrations except the J, L and S samples which recorded 0.081, 0.071 and 0.092 ppm , respectively.The concentrations of Ni recorded 0.03,0 .05,nil,nil,0.06 and 0.01 ppm , respectively in the samples F,I,L,R and 20.   The previous values less than the acceptable limits but other exceed thes values, while the samples do not recorded values that exceed the acceptable limits of Zn in WHO or Iraqi standards.Bacterial growth was recognize in the samples A,C,I,J,L,O,P,Q and R with numbers 46,9,31, 11,1,11,24,19 and CFU\g , respectively. Also , yeast found in the following studied samples F,G,J,L,M,N and T, respectively. but do not recorded in other samples, while molds were founding with the following numbers 1,34,39,11,17,7,16,17,9,6,25,13,29 and 8 CFU\ g in the samples A,B,C,D,E, G,I,J,K,N,O,P,Q and R, respectively .According to the previous results, it can conclude that the tested samples of candy not suitable for healthy use by children.
