The invention discloses a method for preparing ceramide through emulsification and fermentation and application of the ceramide. The method comprises the following steps: inoculating yeast cells intoa fermentation medium for emulsification culture, adding olive oil every day on the 3rd-6th day of emulsification fermentation culture to obtain an emulsified bacterial liquid mixture; carrying out solid-liquid separation, and carrying out demulsification separation on the obtained liquid to obtain a ceramide-like extract A and an emulsion-like water phase; carrying out extraction separation on the emulsion-like water phase to obtain a ceramide-like extract B; combining the obtained ceramide-like extract A and ceramide-like extract B, and conducting drying to obtain the ceramide-like extract.With the emulsification fermentation method, a large amount of ceramide-like substances Mels can be secreted into fermentation liquor, so any derivatization process is not needed, operation is simple,extraction and separation are convenient, fast action is realized, and the limitation of regional climate is avoided; and most importantly, the produced ceramide-like extract is high in safety and low in production cost, can be industrially produced on a large scale, and can replace high-cost ceramide to be applied to the fields of cosmetics and the like.
