“…Although one could have expected somewhat lower lipid content for spring samples because of potentially lower food intake during winter season, those data do not describe a clear seasonal influence on the lipid content for both species. Globally, the reported mean values are similar to the few available values for Kazakhstan, as reported by Konuspayeva et al (2010) 5.9 ± 2.5%, Serikbaeva and Toktamysova, 2000 5.2%, and Urbisinov (unpublished results) 5.1%.…”

Levels and trends of PCDD/Fs and PCBs in camel milk (Camelus bactrianus and Camelus dromedarius) from Kazakhstan

a b s t r a c tTo date, despite the fact it represents a very important part of the national dairy production, no data are available concerning the concentrations of polychlorinated dibenzo-p-dioxins (PCDDs), polychlorinated dibenzofurans (PCDFs), and polychlorinated biphenyls (PCBs) in camel milk from the Republic of Kazakhstan. Selected PCDDs, PCDFs, and PCBs were measured in pools of milk from camels (n = 15) located in various places of Kazakhstan (Almaty, Atyrau, Aralsk, Shymkent) and sampled at two different seasons for two different species (Camelus bactrianus and Camelus dromedarius). Non-dioxin-like (NDL-)PCB concentrations (6.3 ± 2.7 ng g À1 fat, median 5.1 ng g À1 fat, range 0.6-17.4 ng g À1 fat) were far below the maximum value of 40 ng g À1 fat proposed by the EU. Dioxin-like (DL-)PCB concentrations (1.7 ± 0.7 ng g À1 fat, median 1.5 ng g À1 fat, range 0.3-4.2 ng g À1 fat) and the NDL-PCB to DL-PCB ratio (4.3) were similar to what is reported in EU for cow-based dairy products. PCB 52 and PCB 101 appeared to be proportionally more present in Kazakh camel milk samples (>60% of the sum of the 6 indicator NDL-PCBs) than in European cow milk samples (<10% of the sum of the 6 indicator NDL-PCBs), indicating possible differences in the route of exposure to PCBs in Kazakhstan. PCB 105 and PCB 118 appeared to be present at higher concentrations in camel milk (>80% of the sum of the 12 DL-PCBs). PCB 105, PCB 118 and PCB 156 were the major congeners for DL-PCBs, accounting for 92% of the sum of concentrations of DL-PCBs (88% for Belgian cows). In terms of TEQ, PCB 126 and PCB 118 are the major contributors and represent, respectively, 80% and 14% of the DL-PCB TEQ WHO05 concentrations. No significant interracial or geographical trends were observed for NDL-and DL-PCB profiles. However, concentrations of all DL-PCBs appeared to be significantly higher for samples collected in Atyrau region. 2,3,7,8-TCDD level (mean 0.08 ± 0.07 pg g À1 fat, median 0.08 pg g À1 fat, range 0.00-0.18 pg g À1 fat, 60% > LOQs) were very low for all samples and 2,3,4,7,8-PeCDF was the major contributor (27%) to the PCDD/F TEQ WHO05 . Considering the total TEQ WHO05 (sum of DL-PCBs and PCDD/Fs), DL-PCB and PCDD/F contributed for 73% and 27%, respectively. A decrease of only 1% of the total TEQ was observed when using the TEF WHO05 scale instead of the TEF WHO98 scale. Two samples collected in the region of Atyrau exceeded the EU maximum level value of 6.00 pg TEQ WHO98 g À1 fat (6.4 pg TEQ WHO05 g À1 fat and 6.9 pg TEQ WHO05 g À1 fat). Both samples exceeded the EU action level for the sum of DL-PCBs. Based on the fact that camel milk is used to prepare popular traditional fermented drinks like shubat, this suggests that the human exposure in the Caspian Sea region of Atyrau should be expected to be higher than in the other regions studied here.

“…Konuspayeva et al (2010) found that TP decreased from 17.2 to 4.2% in 7 days. The high content of TP in during the colostrum secretion can be explained by the high content of immunoglobulins in mammary secretion at this stage.…”

“…In 2009, El-Agamy reported the amount of iron in camel milk as 0.7-3.7 mg/L (El-Agamy, 2009). In study by Konuspayeva et al (2010), the mean amount of iron in camel colostrum was measured by ICP method resulting in the amount of 2.50 mg/L. Al Haj & Al Kanhal (2010) and Nnadozie et al (2014) reported the mean iron content in camel milk as 0.29 mg/100 g and 0.146 mg/kg, respectively.…”

Evaluation of mineral content and heavy metals of dromedary camel milk in Iran

et al. 2016

The aim of this study was to determine the amount of major mineral compounds and heavy metals of camel milk in Iran. For this purpose camel milk samples were collected from seven regions of Iran include Qazvin, Golestan, Semnan, Sistan-Baluchestan, Khuzestan, Bushehr and Tehran. The samples were analyzed using Inductively Coupled Plasma-Optical Emission Spectrometer (ICP-OES) method. The results showed that among the mineral contents, iron and zinc of camel milk were greater than bovine milk. Based on the codex standard 193-2007 standards, the maximum acceptable limit for lead and cadmium is 20 µg/kg and 10 µg/kg, respectively. The results of this study showed that the measured amounts of lead, cadmium and nickel in all samples were less than the acceptable limit for bovine milk. Bovine milk and dairy products are a poor source of iron, while the obtained data revealed that camel milk is a major source of minerals, especially iron. The camel milk's iron was 10 times more than bovine milk. However, variations in mineral content in camel milk could be due to feed, stage of lactation, milk collection time, drought conditions, environmental conditions and associated analytical methods. Camel milk recommended as a valuable source of food for the human.Keywords: camel milk; mineral element; heavy metal; Inductively Coupled Plasma (ICP).Practical Application: This study allows knowing the amount of some mineral content and heavy metals of camel milk in Iran.
