Very good question! The truth is, it is very important for every consumer to understand how the nutrition label works, and how to interpret apparent and not-so-apparent bits of information.

Very interesting question,

I actually did some research online and found this Japanese journal article, and what I can say is that I am actually quite skeptical. There are a few reasons for my skepticism.

Colors in Plants: Chlorophylls

color-plantsThe colors that we observe in fruits and vegetables are attributed by 4 primary pigments: chlorophylls, carotenoids, anthocyanins, and betalains. Today we will be focusing on chlorophylls. Chlorophylls are green and blue pigments found naturally in the chloroplasts of plants and algae, as well as in photosynthetic cyanobacteria such as spirulina and chlorella. One molecule of chlorophyll contains one molecule of the mineral magnesium, which makes green fruits and vegetables decent sources of magnesium. Notice the long hydrocarbon tail (Fig. 1) of chlorophyll. This chemical feature gives chlorophylls a high solubility in oils and poor solubility in aqueous solutions like water.
