RED PEPPER POWDER COLOR MEASUREMENT BY USING AN INTEGRATING SPHERE …<br />

The CIELa*b* characteristics and C, h* color attributes (Fig. 4) show<br />

that the data are close to that obtained from the reflectance spectrum, as<br />

reference data. The differences are within the error of <strong>de</strong>terminations. We<br />

can conclu<strong>de</strong>, that the use of integrating sphere and digital still camera is<br />

suitable system for the precise <strong>de</strong>termination of the color characteristics,<br />

and based on it, the quality assessment of different pepper pow<strong>de</strong>r brands.<br />
