Stickiness/adhesion is a common textural and physical property that is possessed by a wide range of products including food, cosmetics, pharmaceutical products and, of course, adhesives and adhesive tapes. Testing this property is key to understanding, manipulating and controlling the performance or enjoyment of a product whether it is eaten, spread on the skin or used as an important everyday tool or medical requirement. Stickiness/adhesiveness/bioadhesion can be a highly desirable requirement of a product or can be a negative undesirable property. This is a property where the Texture Analyser excels in measurement. Exponent software has a unique test (the Adhesive Test) which allows the control of force that a probe comes down onto the sample to achieve a controlled bonding between the two surfaces for a chosen period of time. After this bonding preparation stage the probe withdraws and the adhesion properties to separate the two surfaces is measured.
