The white stuff in soy sauce is usually harmless film yeast, a natural byproduct of fermentation that forms a thin film on the surface, but it can also be solidified amino acids or bacteria, though actual mold is rare in finished, sealed soy sauce; if it's a floating film or sediment, skim it off, but if it looks fuzzy or changes color significantly (especially to black/green), discard it as it might be spoilage, notes Quora and Reddit users.
Well soy sauce is made with koji (a mould). It appears this bottle/batch was compromised. Could be temperature, oxygen, humidity or even a contaminant. Throw it out.
As it oxidizes, you may notice that it turns darker, and the aroma and flavor becomes stronger, while subtler flavors disappear--this is normal, and safe to consume. Brigman warns that ``if a mold should develop, or the soy sauce has an off or foul odor, or has changed in texture, it must be discarded.''
Absolutely not. Throw it away. Any sign of fermentation or mold in tomato (or any high acid) products should immediately be thrown out.

Taste receptors are present in spermatogenic cells during spermatogenesis. They reduce T1r3 expression in Tas1r3 knockout mice and mice fed on high doses of sodium saccharin, reducing sperm viability and causing abnormal sperm morphology. Decrease T1r3 expression subsequently reduced the testosterone and cAMP levels.
Eating moldy foods may cause nausea, vomiting, diarrhea, and abdominal cramps due to the mycotoxins present. Still, some molds may also lead to allergic reactions, such as itchiness, rashes, nasal congestion, sneezing, and runny nose.
To simplify, the straight answer: Yes, heat can kill mold spores, but cooking moldy food doesn't make it safe to eat. Why? Indeed heat (above 140°F or 60°C) can kill most mold spores, especially at boiling (212°F/100°C) or oven temperatures (350°F/175°C or higher). However, mycotoxins are heat-resistant.
Crops that are frequently affected by Aspergillus spp. include cereals (corn, sorghum, wheat and rice), oilseeds (soybean, peanut, sunflower and cotton seeds), spices (chili peppers, black pepper, coriander, turmeric and ginger) and tree nuts (pistachio, almond, walnut, coconut and Brazil nut).
However, its rich flavor might have diminished over time. It's crucial to check for any off-putting smells, mold, or unusual changes in its appearance. While consuming expired soy sauce isn't typically harmful, always be cautious and ensure it hasn't developed mold or become unusually viscous.
If the soy sauce has a rancid smell, is significantly darker in color, or has visible mold, it's no longer safe to use.

In some instances, mold can definitely make you sick, especially if you have allergies or asthma. Some people experience symptoms such as constant migraines, headaches or shortness of breath while others report brain fog as well; some may also develop fatigue and depression.
Some fungi and microorganisms can create spores, which are like seeds that help them survive adverse conditions. These spores can survive cooking, drying and freezing.
SOFT Fruits and vegetables with high moisture content can be contaminated below the surface. Porous foods can be contaminated below the surface. Foods processed without preservatives are at high risk for mold.
What are symptoms and effects of mold exposure?
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.
