Determination of Adulteration in Milk Samples by using Geiger Muller Counter

An improved Geiger-counter arrangement for determination of radium content.

Geiger-counter apparatus in which several counters may be placed in any position relative to each other is described. A circular arrangement of counters to give a counting rate approximately independent of the position of a so urce near the center of the circle is discussed. The relation of the I osition of the source to the counting rate of a single Geiger counter is discus ed. A method of cal...

Investigation of Goats’ Milk Adulteration with Cows’ Milk by PCR

Goats’ milk adulteration with cows’ milk is becoming a big problem. In the past, the urea-polyacrylamide gel electrophoresis assay with different motility of αS1-casein has been applied for the identification of cows’ milk adulteration. The detection sensitivity is 1.0%. The aim of this study was to develop a faster and more sensitive method to detect cows’ milk which may be present in adultera...

Adulteration of Milk

Adulteration of Human Milk

The necessity for testing human milk destined for milk banks in order to eliminate specimens which have been adulterated with water or cow's milk has been widely recognized since the introduction of such banks in 1910 (Mackintosh, 1947). In some centres, however, no tests for adulteration seem to be used, in spite of the fact that the mothers providing milk for these banks are not supervised be...
