Introduction

 


Fat and moisture testing for foodstuff samples has traditionally been done by wet chemistry techniques, which are laborious and time consuming and often involve skilled technicians and hazardous solvents. Various rapid techniques (TD-NMR, NIR, FT-IR, and FT-NIR) have been introduced, but none have been universally accepted due to the need for often extensive calibration development and maintenance.

 


The ORACLE is a rapid time domain NMR (TD-NMR) instrument incorporating breakthrough technology that allows for direct determination of fat/oil in foodstuffs. Unlike other rapid techniques, the ORACLE is able to completely isolate the detection of fat in complex matrices which eliminates the need for calibration development. To allow for rapid moisture/solids as well as fat testing, the ORACLE can be coupled with a SMART 6 moisture/solids analyzer.

 


To demonstrate the ability of the ORACLE and SMART 6 to accurately and reliably determine the fat and moisture content in dairy samples, an assortment of 11 samples were obtained and analyzed. The samples were selected to represent a range of both matrix types as well as relative component concentrations.
