What makes carrot bits turn green in carrot pineapple bread? (And are they safe?)
Sometimes, a couple of days after its cooked, the carrot bits inside a carrot pineapple bread turn green.
Normally, I'd assume that a food that doesn't start green and winds up that way is moldy, but, A) it's only happening to the carrots, and B) it's happening inside the loaf, not on the outside, and it doesn't look like mold- more like the carrots themselves are changing color.
What's causing this, and is it still ok to eat?
In case it matters, the other ingredients are vegetable oil, cinnamon, salt, eggs, sugar, baking soda, baking powder, flour, and vanilla.

Here is a super in-depth analysis of what may cause the carrot to turn green:

Unfortunately, it doesn't come to any hard conclusions. It does make it clear that it's not simply pH though, as a carrot will remain green even in a 0.1 M solution of sodium hydroxide.
It does provide an anecdote about a baker that had a similar issue, and how they solved it:
[they overcame] it with a change in formula of baking powder and a good clean out of equipment.
Perhaps this could apply in your case? It might be a reaction from your cookware in combination with other factors? What if you remove the pineapple? Does it still happen? Perhaps trying a different brand of baking powder may work.
One thing is for sure, it's definitely not mold, and I'm very confident that it's harmless.

Why did my carrots in my carrot cake turn green?
Harold McGee, author of On Food and Cooking, explains that carrots turn green when the batter \u201ccontains too much baking soda, or when the soda isn't evenly mixed in the batter.\u201d Carrots contain pigments that are sensitive to changes in pH balance.Why is there green in my carrot?
What it is: The carrot was likely exposed to the sun, causing chlorophyll to develop and color the flesh green. Eat or toss? The orange part of the carrot is fine; as for the green top, it's said to not taste so great, so go ahead and chuck it in the compost.Why does pineapple turn green?
All of a pineapple's sugar comes from the starches in the stem of the plant. Once that source is cut off, the pineapple cannot make more sugar on its own. Green pineapples will usually change color as well. It's possible that the pineapple will become even more acidic if stored too long.Why did my muffins turn green?
This happens when the muffin mix contains a lot of baking soda or also when the baking soda is not mixed properly in the batter. This could result in formation of some alkaline pockets throughout the batter which gets in contact with the fruits. Blueberries are rich in anthocyanin pigment especially under their skin.More answers regarding what makes carrot bits turn green in carrot pineapple bread? (And are they safe?)
Answer 2
This can commonly happen with carrots, blueberries and sunflower seeds. It's due to having a batter that's too alkaline or not having the baking soda evenly mixed throughout the batter. Anthocyanin and other food color pigments are sensitive to pH level. When they are in contact with more alkaline surroundings they will change color. While maybe a bit unappetizing in color, it's still safe to eat.
Either make sure your baking soda is completely mixed with the dry ingredients and evenly moistened, or try decreasing the soda slightly.
Answer 3
I made scones two days in a row with the exact same ingredients minus the lemon juice on day 2. The carrots turned green. Also, the first day, I mixed ingredients with the kitchen aid mixer and on the second day I hand mixed. I'm thinking lemon juice.
