Please in support of the question, I needed to determine colour change for my dried tomato samples with different treatments. Samples colour properties such as lightness and redness increased after drying for the attractive samples, but these parameters decreased for the unattractive sample which was badly affected by processing conditions. The colour change of this unattractive sample now happened to be the smallest compared to the fresh samples because it was more darkened which implies reduced lightness. While those which are attractive had higher colour differences due to improved lightness.
Whereas, on the other hand, the dried control sample had higher lightness index, and when used as the standard gave better correlation of the samples with respect to the human eyes i.e. those that are attractive had lesser colour change in this case in which the unattractive ones had the highest colour change.
With the aforementioned, which one is more justifiable to be used as the standard, the fresh or the dried control?
Thank you.
The L, a, b of fresh tomatoes. You can then calculate change in L, a, b, and calculate color change
@Clinton okonkwo please read the note attached to the question, as it appears I have a peculiar scenario here. Thanks
Hello Mr Obajemihi,
If the pretreatment is same. You can try to calculate it with L, a and b of pretreated sample.
But in general it is calculated with L, a and b of fresh samples.
