GST-01 Gel Strength Tester
Application
Gel strength can be defined as a measure of the ability of a colloidal dispersion to develop and
retain a gel form based on its resistance to shear.
Bloom is the specific measure for the gel strength/firmness of the gelatin. The Bloom values
are determined by measuring the force (in g) required to depress the surface of a 6.67%
gelatin gel (after gelling 16-18 hours at 10°C) to a distance of 4 mm. So,
the higher the value, the stronger the firmness of the gel.
The Bloom in grams is measured by a specified probe to depress the
surface of gel.
About Gel Strength gcm
The gel strength test was originated from surimi industry. In the test, a punch probe of a
specific diameter and length is used to compress the surface of a gel specimen at a constant
deformation rate, until puncture occurs. Normally the speed used is 60mm/min and probe
φ5mm.
Gel strength is based on force×distance, thus having a unit of “gcm”.
