Milk with high developed acidity, or having calcium and magnesium compounds in greater than normal amounts, will coagulate when alcohol is added. Increased levels of albumen (colostrum milk) and salt concentrates (mastitis) may also results in a positive test.
The alcohol test serves as a crucial assessment tool for evaluating the quality of raw milk in the dairy industry. By determining the potential for coagulation upon thermal processing, this test aids in producing superior dairy products such as UHT milk, evaporated milk, and milk powders.
22 de mar. de 2022 · Alcohol Gun. Milk control guns used in milk analysis are used to detect the acidity progression in milk in a practical way. For this process, 68% ethyl alcohol is used. If there is coagulation in the milk, pasteurization process does not continue.
microorganisms ferment milk sugar (lactose) to lactic acid and milk acidity increases to about 9.0 SH, such milk precipitates when the equal amount (alcohol single test) of alcohol is added. When double amount of alcohol is added (alcohol double test), milk precipitates already at lower acidity such as 8,0‐8,5 SH.
This chapter reviews the history of the use of the ethanol stability test and surveys the milk compositional factors influencing its result. Developed originally as an indicator of fresh milk quality, it now finds use in some countries as a warning of the lack of...
