Title:

MEASUREMENT DEVICE AND METHOD FOR ESTIMATING MOUTHFEEL AND BEHAVIOR OF ALIMENTARY BOLUS DURING EATING AND SWALLOWING

Document Type and Number:

WIPO Patent Application WO/2017/026090

Kind Code:

A1

Abstract:

The present invention addresses the problem of developing a device with which it is possible to precisely and easily measure, evaluate, and quantify the dynamic properties of an alimentary bolus that simulates the swallowing of a wide variety of types of food products, and providing a method for estimating the mouthfeel from the dynamic properties by using the device. A measurement device for simulatively replicating a state of swallowing an alimentary bolus, and measuring the motion and shape of a specimen used as a simulative alimentary bolus, wherein the measurement device is provided with: a tilted plate having a tilted surface; a supply unit (a) for supplying a specimen onto the tilted surface; a supply sensor (c) for detecting the specimen supplied from the supply unit (a) onto the tilted surface; an arrival sensor (d, f) for detecting the specimen moving downward to a prescribed site on the tilted surface; a data logger (i) for recording the output from each of the sensors; an upper-surface camera (h) for imaging, from a position above the inclined surface, the specimen moving downward on the inclined surface, and generating an upper-surface image; a side-surface camera (g) for imaging, from a position to the side of the inclined surface, the specimen moving downward on the inclined surface, and generating a side-surface image; and a calculation unit for using at least one of the output from the data logger (i), the side-surface image, and the upper-surface image to calculate a state parameter that represents the state of the specimen moving downward on the inclined surface.
