Texture analysis is the mechanical testing of food, cosmetics, pharmaceuticals, adhesives and other consumer products in order to measure their physical properties. Because of its adaptability, texture analysis has become commonplace in many industries to measure a specific or range of characteristics or properties relating to the way a material behaves, breaks, flows, sticks, bends etc. Major manufacturers routinely apply texture analysis techniques both in new product development and as part of quality control in all stages of manufacture, carrying out a wide range of measurements to analyse raw materials or excipients, semi-finished goods, packaging and finished products.
It is a cost-effective method to determine the effects of raw material or excipient quality or the adjustment of formulation or processing variables on end product acceptability – whether this is to measure the ‘mouth feel’ properties of food, the flow properties of creams and pastes, the break or bend of a product or the tackiness of adhesives.
