The invention discloses a sweet oil condiment. The sweet oil condiment is prepared through fermenting two strains, and is prepared in a manner including the steps of processing raw materials, mixing flour and saline water to obtain flour paste, liquifying the flour paste, steaming the liquified flour paste, performing inoculation on the steamed flour paste, and performing heat preservation and fermentation on mixed materials so as to obtain mature soy sauce mash; squeezing the mature soy sauce mash so as to obtain oil materials, performing primary disinfection on the oil materials, blending the oil materials after primary disinfection; and performing secondary disinfection, and discharging sweet oil products. The obtained sweet oil is sweet and fresh, light in color, amber in color, rich in fragrance and pure in flavor. According to the sweet oil provided by the invention, bold innovation is performed on the culture of the strains, the fermentation temperature and the fermentation time in the preparation process of the sweet oil, compared with conventional sweet oil prepared by a conventional technology of weather exposure and natural fermentation, the sweet oil provided by the invention has the advantages that the production cycle is shortened to 20 days from the original 6-12 months, the labor efficiency is improved, the physical labor intensity of workers is alleviated, and all the characteristics of sweet oil products are reserved. According to the sweet oil prepared through heat preservation and fermentation, a liquid enzyme method technology is adopted, the mechanized production and the pipelining production of the sweet oil are realized, and the physical labor intensity of the workers is alleviated. The utilization rate of raw materials is increased, and the labor efficiency is improved. The sweet oil condiment belongs to the innovation of a bio-fermented technique in a brewing condiment trade.
