Description
Haiyi Yu and co-authors study how storage conditions affect a toxin that a common mold makes on apples. Their 2025 paper isolates the fungus Penicillium expansum from an apple and grows it on apple puree agar. The toxin, patulin, is a food safety concern in apple products, so the team varies acidity, temperature, and humidity to see what drives its production.
The mold made the most patulin at fifteen degrees with high humidity and strong acidity. It grew fastest at warmer temperatures under similar moisture. Almost no toxin appeared at five degrees even after two weeks of slow growth. The authors conclude that cold storage below five degrees can hold patulin risk down after harvest. Their findings give packers a clear, testable storage rule.
