Chewing Simulator Provides Sensory Information

Technology No. 20170420

Sensory information on chewing experience

Artificial Resynthesis Technology (ART-5) is a mechanical mouth that tests food products and dental materials by simulating the mechanics of the human chewing process. It provides information on the environmental conditions found in the human mouth. The chewing machine or artificial mouth has a computerized feedback control that mimics the human chewing motion, especially its ability to adjust chewing speed and path in response to food texture. The device provides sensory information on appearance, sound, texture, smell and taste for evaluating food products. The device also tests wear patterns for dental materials and orthodontic appliances.

Reproduces human chewing motion

Although equipment exists to measure food parameters such as hardness and stickiness, currently there are no all-encompassing machines which reproduce the human chewing motion and provide multi-sensory information. Originally designed for assessing dental/orthodontic materials, ART-5 provides fast, objective, reproducible and quantitative measurements on food texture and other sensory parameters. It can reduce the costs associated with panel tasting, and speed up the design, optimization and introduction of new food formulations.
