Natural Green Food Coloring Sunflower Seeds

Isn’t the dark forest green color of this natural food dye amazing? Can you guess what I used as natural green food coloring? 😀 Hint: It’s not spinach, peas, kale, stinging nettle, avocado or any other vegetable. It’s also not matcha powder, mint leaves, pistachios, pumpkin seeds, pandan leaves, wheatgrass or spirulina. 😉

It’s sunflower seeds! 😀

After baking these great natural green sunflower seed cupcakes, I was so fascinated by the dark green color that I had to experiment a bit more with natural green food coloring made with sunflower seeds.

Sunflower seeds contain chlorogenic acid. Chlorogenic acid turns green in an alkaline environment! Chlorogenic acid is safe to eat. Chlorogenic acid can also be found in tea, coffee, bush beans, beetroot, cabbage, carrots, peas, tomatoes, zucchinis, soy beans and spinach (source, pdf).

Natural Green Sunflower Seeds


  • 1/2 cup sunflower seeds
  • 2 cups water
  • 1/2 tbsp baking soda

Bring sunflower seeds, water and baking soda to a boil – be careful, it’ll foam a lot! Simmer for 20 – 30 minutes. Drain the sunflower seeds: they’re now yellow. Spread them out on a plate and let them oxidize for some hours or overnight. On exposure to air, the sunflower seeds become emerald green, dark forest green and some almost black!

    1. I also didn’t know that sunflower seeds turn green with baking soda until I accidentally found the green sunflower cupcake recipe. 😉
