Gel Strength Tester

GST-01 Gel Strength Tester

Significance

Gel strength is an important quality parameter in various industries, especially in the food industry. For example, in the surimi industry, gel strength is a key factor in determining the texture and quality of surimi-based products like imitation crab meat. It affects the product's mouthfeel, firmness, and overall sensory attributes.

The gel strength test is a valuable tool in assessing the texture and quality of gels, particularly in industries like surimi, where the consistency of gel-based products is crucial for consumer satisfaction.

About Gel Strength gcm

The gel strength test is a procedure used to evaluate the texture and quality of gels, especially in food industries like the surimi industry.

Purpose: The gel strength test measures the ability of a gel to withstand deformation under an applied force. It is commonly used to assess the texture and consistency of gels, such as those formed from proteins in surimi (a paste made from fish or meat).

Principle: 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”.
