Milk and dairy products are avowed as rich source of dietary minerals. Globally, the popularity of ice cream is increasing due to its nutritional benefits and appealing tastes. Therefore, the main objectives of this study were: (a) to determine the concentration of macro-elements (K, Na, Mg, Ca, and P) in commercially available ice cream in Bangladesh; (b) to point out their contribution to our daily diet formulation. Based on the popularity, and availability, seven leading brands were selected and five samples from each brand were randomly purchased irrespective of their types, flavour, taste, and price. The concentration of macro-minerals were quantified using Inductively Coupled Optical Emission Spectrophotometer (ICP-OES) and UV-Vis Spectrophotometer. The average concentration (fresh weight) of studied elements had shown a descending order of Ca (1529.41±278.88) > K (1363.69±198.68) > P (1187.76±231.23) > Na (569.79±141.14) > Mg (194.90±68.59) mg kg-1. Pearson's correlation matrix among the different metals revealed a significant correlation between K-Na (r = 0.418) and K-Mg (r = 0.408) at p < 0.05 levels. The average estimated daily intake (EDI) of K, Na, Mg, Ca, and P were found 40.97, 17.12, 5.85, 45.94, and 35.68 mg day-1, respectively, which indicated none of the studied samples exceeded the recommended daily allowance (RDA). The consumption of ice cream (30.04 g day-1) showed 0.87-7.34% contributions of macroelements to our daily diet. The present study concludes that ice cream could be considered as a possible source of essential minerals (especially Ca, and P). However, to assure the food quality and to create a balanced diet, regular monitoring of milk and dairy products is strongly recommended. [ABSTRACT FROM AUTHOR]

Ice cream is a popular dairy product in the world. Its chemical and microbial quality has always been remarkably important to consumer. The aims of this study were to investigate chemical and microbiological quality of ice cream from four companies (Igloo, Kwality, Polar and Baby) sold in Sylhet city, Bangladesh. Total solids (TS), Fat, Protein, Ash, and Acidity content, total viable count and coliform counts were measured Standard procedure. There were highly significant differences (P<0.001) within the chemical parameters of ice cream from different companies. Ice cream from Kwality Company contained 3.48% protein, 36.30% total solids, 13.00% fat, 1.05% ash and 0.22% acidity which were higher than other companies. Total viable bacteria were in the range of 1942cfu/gm to 3692cfu/gm. Coliform counts of the ice cream samples from Igloo, Kwality, Polar and Baby were 16.00, 12.42, 36.17 and 47.17cfu/g respectively. Ice cream from Kwality Company was superior to other companies on the basis of chemical and microbial parameters. [ABSTRACT FROM AUTHOR]

Ice cream is a popular frozen dairy product and a possible source of dietary minerals. However, ice cream may also contain toxic metals, which may cause several health implications. The current study aimed to determine the content of toxic elements in ice cream samples using inductively coupled plasma-optical emission spectrometry (ICP-OES) and to assess the health risks of consumers based on target cancer risk (TCR), target hazard quotient (THQ), and hazardous index (HI). The determined concentration (median, range) of all studied elements had shown a descending order of Al (9.36, 5.37-14.26) > Zn (5.94, 1.95-10.22) > Cu (1.73, 1.02-3.77) > Ni (0.95, 0.67-1.80) > Fe (0.79, 0.10-1.64) > Cr (0.43, 0.28-0.73) > Mn (0.42, 0.11-1.03) > Pb (0.34, 0.09-0.79) > Cd (0.08, 0.04-0.14) mg/kg (fresh weight). The values of THQ and HI (except 16% for children) were lower than the maximum threshold risk limit (TRL = 1.0), indicating no potential non-carcinogenic health effects might occur. Similarly, the TCR of Cr and Pb for both adults and children was within the permissible limit of 10 -4 -10 -6 , which suggested that the consumer would not experience potential lifetime carcinogenic health risks. However, the overall analyses revealed that the consumption of ice cream is almost safe for people, but the combined impact of all metals (HI) in some samples is a matter of health concern. Henceforth, regular monitoring of toxic metals in ice creams should be done to assure food safety and hygiene.
