Availability of Portable Endotoxin Test System in Commercial Milk and Milk Drinks

Abstract

We investigated the availability of the portable endotoxin test system by the chromogenic method for milk hygiene. We measured endotoxin concentrations of commercial milk and milk drinks by the portable endotoxin system and conventional system of the kinetic turbidimetric method. We also evaluated the correlation and regression between the values of endotoxin concentrations using both methods. The endotoxin concentration values were strongly correlated (R ＝0.99), and a good linear regression was recognized for those logarithms. Therefore the portable endotoxin test system may be able to measure endotoxins in milk and milk drinks.
