The correlation between speck count and semolina color determined by tristimulus method using flatbed scanner

الملخص EN

In this study, Tristimulus color coordinate measurements were performed with Minolta spectrophotometer on thirty-nine semolina samples, and computed using digital image analysis (DIA).

Both L* Minolta reading and L* computed values by DIA were negatively correlated with brown, black, and total speck counts.

The highest correlation was at resolution of 200 dpi.

For a*, there was no significant correlation between a * Minolta reading and brown, black, or total speck counts, but there was a positive and significant correlation (P < 0.05) between a* computed values by DIA and brown, black, and total speck counts.

The highest correlation was at resolution of 200 dpi and 400 dpi.

Both b* Minolta reading and b*computed values by DIA were negatively correlated with brown, black, and total speck counts.

The highest correlation was at resolution of 600 dpi.
