The hairy mold is often used in fermentation processes such as curd, hairy tofu, etc. It can produce protease, lipase and other enzyme systems to give food better flavor and nutrition.
Hairy tofu is artificially fermented so that a layer of white fuzz grows on the surface of the tofu, but these white fuzz are hairy molds. Molds, also known as filamentous fungi, come in many varieties, the common ones being Rhizopus, Trichoderma, Aspergillus, Penicillium, and Aspergillus flavus.
