Purple mold on bread is often a type of fungus, potentially a variant of black bread mold (like Rhizopus stolonifer), a Penicillium species, or a reaction from ingredients like psyllium husk, but generally, moldy bread should be discarded as it can cause health issues, even if it looks harmless. It might also be a harmless discoloration from antioxidants or iron in the flour reacting, but you can't know for sure without testing, so throwing it out is safest, especially with fuzzy, growing patches.
What I found next has likely been experienced by nearly everyone: Bread mold! We've all seen it — that purple-grey, almost greenish fuzz that slowly takes over our various bread products just short of their expiration date. That fuzzy mold is Rhizopus stolonifer, from the fungal order Mucorales.
However, as attractive as the color might seem, purple molds are quite dangerous. Just like black mold, they contain a large percentage of mycotoxins, meaning they can also cause a variety of conditions ranging from allergic reactions to respiratory problems.
As other people said, it's the psyllium husk. Specifically, this tends to happen with older psyllium husk. If you purchase a brand new bottle, that should solve the problem. That said, the purple color isn't harmful!
While less common, purple mold is typically a species of Fusarium and can be found on wood, wallpaper glue, and water-damaged materials. In some cases, it can produce mycotoxins, making it a concern for air quality.
This is what I read It is a sign that the food has gone bad and should be thrown away. The mold may also be found on clothing, furniture, or other surfaces. Purple mold can cause allergies and respiratory problems, so be sure to address the problem as soon as you notice it, or call a professional right away.
While there are many types of mold including mildew, both black mold and toxic black mold spores pose the greatest risk and are most difficult to treat. The different forms of black mold do have various toxicity levels and are identifiably different.
Mold can produce harmful mycotoxins that can make you sick. Consuming moldy bread could cause food poisoning symptoms like nausea, vomiting, diarrhea, or breathing problems. - The mold may also have spread throughout the loaf, even if you can't see it. It's best to discard the entire loaf if any mold is found.
Psyllium husk contains an antioxidant in the outer layer of the psyllium husk seed called anthocyanin that can turn your bread or other baked good purple if too much of the powder is used.
"Whenever the food is soft or semi soft, it's not recommended to cut out the mould because … the toxins that mould produce might penetrate the depth of the food." Dr Vaskoska says its best to throw things like sauces, pastes, and bread away.
If you have mold allergies, black mold can make you sick. Black mold produces spores, which can enter the air.
Mold toxicity warning signs often include persistent fatigue, brain fog (memory/focus issues), chronic sinus/respiratory problems (cough, congestion, wheezing), digestive issues (bloating, IBS-like symptoms), mood changes (anxiety, depression), neurological symptoms (numbness, dizziness, ringing in ears), skin issues (rashes, itching), and inflammation-related pain (joint/muscle aches, night sweats), with symptoms often improving away from home and worsening upon return, indicating an environmental link.
Also, FYI, toasting your bread will not kill the mould on it, so don't even go there.
To simplify, the straight answer: Yes, heat can kill mold spores, but cooking moldy food doesn't make it safe to eat.
Rhizopus stolonifer is commonly known as black bread mold. It is a member of Zygomycota and considered the most important species in the genus Rhizopus. It is one of the most common fungi in the world and has a global distribution although it is most commonly found in tropical and subtropical regions.
The answer has to do with acidity and time. The purple tint appears only in an acidic environment, and most baked goods aren't acidic enough to cause the reaction. But thanks to the acids produced by yeast as it ferments, bread dough does have what it takes.
How can you tell if your loaf of sandwich bread has gone bad? Usually you can tell because it has a sweet smell. This could mean it's gone mouldy with a white invisible mould, before it turns green!
However, there is no substantial scientific evidence to suggest that psyllium husk causes cancer. In fact, the opposite may be true: fibre-rich diets, including psyllium, have been linked to a reduced risk of colorectal cancer.
The average person likely won't get sick from ingesting small amounts of mold, the experts note. However, eating larger quantities of mold may result in nausea or stomach upset. Chances are you won't be able to eat very much mold because humans have a natural aversion to spoiled foods, Wee notes.
So, while your high school science teacher was right about penicillin being made from mold, it is not a good idea to try to get this bacteria-fighting agent from moldy bread. The next time you're craving a PB&J or grilled cheese, check out your bread carefully.
Discard all moldy food except for hard cheese and firm fruits and veggies. In the case of hard cheese and firm fruits and vegetables, you can cut off the moldy area, removing at least 1 inch below the mold. Be sure not to cut through the mold and cross contaminate.
Purple Mold
Purple is not a common color for mold to be, but if you do see it, it's probably a color variant of toxic black mold—Stachybotrys chartarum.
Dead mold appears flaky and powdery, unlike living mold that appears moist and grows in various colors, such as white, black, or yellow.
Mold is a form of fungus that grows both indoors and outdoors and thrives in warm, damp, and humid environments. There are five categories of toxic mold: Cladosporium, Penicillium, Fusarium, Aspergillus, and Stachybotrys.
