Why does aloevera smell musty?

Aloe vera can have a musty smell due to the presence of certain organic compounds and the natural decomposition of its plant material. When the leaves are cut or damaged, enzymes and microorganisms can create a fermentation process, leading to the development of off-odors. Additionally, if aloe vera gel is stored improperly or for an extended period, it can spoil, contributing to a musty scent.
