The invention discloses a process for
cutting rapeseed oil at a low temperature of 120 DEG C, which is used for making scallion and ginger
rapeseed oil, and relates to the technical field of compound
seasoning manufacturing. A special device with a digital pressure pulse hot
processing system is used in a matched manner, ginger and scallion are used for providing
moisture, pressure pulses are generated in a
flash evaporation manner, and
flash evaporation is repeated for 5-7 times at the temperature of 120 DEG C, so that the raw
rapeseed oil is obtained. After
moisture which contains strong raw rapeseed oil
flavor and ginger and scallion
flavor and accounts for 80% or above of the total weight of ginger and scallion is discharged, the temperature in the kettle is reduced to 100 DEG C again, the materials are discharged out of the device, oil residues are separated or not separated, and the ginger and scallion rapeseed oil which is very strong in ginger and scallion
flavor and cooked rapeseed oil flavor is obtained. According to the invention, only the energy of stir-frying ginger and scallion is utilized, two events of
cutting rapeseed oil and stir-frying ginger and scallion are realized at the same time, the efficiency is improved, and the energy is saved. Meanwhile, the
food safety, the production safety and the
environmental protection safety are substantially improved. The whole process is easy to operate, safe, stable, free of
open fire and capable of achieving digital production.
