Detection of potassium,calcium,sodium,magnesium,copper,iron,zinc concentration in Xinjiang Bactrian milk Camel colostrum

The content of potassium,calcium,sodium,magnesium,copper,iron,zinc in Xinjiang Bactrian camel colostrum changes in the lactation period.By flame atomic absorption spectrometry were determined,recovery was between 92.45%～110.85%,the relative standard deviation less than 5%,it showed that the method has good accuracy and precision.The concentrantion of potassium was highest in Xinjiang Bactrian camel colostrum,followed by sodium,calcium and magnesium.The concentrantion of Ccopper,iron,zinc content in camel milk does did not meet the minimum detection limit of the instrument.In lactation 1~6 days,calcium and magnesium concentration changes was relevant,significant difference.The concentration changes of sodium,calcium and days of lactation was relevant,significant difference.Compared with bovine milk,the concentration of potassium,calcium,sodium,magnesium are higher in Xinjiang Bactrian camel colostrum.Drinking camel milk is an effec-tive way as a supplement of potassium,calcium,sodium,magnesium elements needed by human body.
