DAIRY – Relating rheology and tribology of commercial dairy colloids to sensory perception

PCS Instruments: MTM
Summary: This study used tribology to understand how dairy products feel in the mouth. Full-fat yoghurts and cheeses showed much lower friction (better lubrication) than low-fat versions, especially at low speeds, thanks to fat droplets forming boundary layers. Tribology explained sensory differences better than bulk rheology, especially for creamy textures.
