Rapid Determination of Milk Solids by Microwave Heater and Electrobalance

Abstract

A new instrument consisting of a microwave heater and an electrobalance was developed and tested for precision and accuracy against a gravimetric reference method for determining total milk solids. Linear regression of percent value of total milk solids by new method on those by the gravimetric method (Y = 1.014X – .160) was obtained and the standard deviation from regression was .03% total milk solids. Thus, the precision and accuracy of this new method was excellent. In addition, the new instrument is faster and easier to operate than an official method such as AOAC Method 1 for total milk solids. © 1977, American Dairy Science Association. All rights reserved.
