Abstract

In the food industry there are many types of product that are in the form of
particles, granules or grains. Consistent material size and quality within any
given sample is an important requirement that is well known in industry. In
addition it is possible that samples of material may be of unknown type or
have been subject to adulteration, thus making material authentication a real
requirement. The present work implements an advanced, but cost-effective,
digital imaging and image processing technique to characterize granular
foodstuffs either in real time process control or in an off-line, sample-based,
manner. The imaging approach not only provides cost-effective and rugged
hardware when compared with other approaches but also allows precise
characterization of individual grains of material. In this paper the imaging
system is briefly described and the parameters it measures are discussed.
Both cluster and discriminant analyses are performed to establish the
suitability of the measured parameters for authenticity study and a simple
fuzzy logic is implemented based on the findings. Tests are performed,
using rice as an example, to evaluate the performance of the system for
authenticity testing, and encouraging results are achieved
