Another chemical reaction that causes major food spoilage is nonenzymatic browning, also known as the Maillard reaction. However, a relative few fungal species are phytopathogenic, cause disease (e.g., infections, allergies) in man, and produce toxins that affect plants, animals and humans. Mold is a non-scientific term for many types of fungi - unwanted, unappealing patches of black, brown, yellow, pink, green, smelly, fuzzy growths.
