A bulk analysis test method is used when it is not practical or representative to test an individual sample as a whole or component piece - the product sample is tested 'in bulk'.
Particulate products (e.g. reconstituted meats), or foodstuffs which contain small elements in an individual serving or mouthful (e.g. rice or beans), lend themselves to being analysed by this method.
The procedure then applies compression, extrusion and shear - often in combination - resulting in high forces.
The most widely-used fixture is the Kramer shear cell.
