      So this is weird. I cracked an egg today and put it in the compost. I also put some sunflower seeds in. Two sunflower seeds landed in the eggshell which had some egg white residue still in it. When I picked up the eggshell later, I noticed the white around the seeds turned a vibrant green. Here’s why…
      Sunflower seeds have a high chlorogenic acid (CGA) content (1.9–3.1%). Under moist and alkaline conditions, CGA-quinones covalently bind with proteins to form green trihydroxy benzacradine (TBA) derivatives.
      Very interesting!

        This is an interesting phenomenon! It turns a very intense green. Do you have a picture?
