The wheat germ oil is prepared by extracting wheat malt as a raw material at low temperature, integrates the nutrition essence of wheat, is rich in vitamin E, linoleic acid, linolenic acid, octa-carbon alcohol and various physiological active components, is a valuable functional food, and has high nutritional value. In particular, vitamin E is contained in the crown of vegetable oil, and is known as a functional oil with nutrition and health care effects.

The existing wheat germ oil is basically produced by squeezing or leaching, and in the production process, due to various factors such as different maturity degrees of raw materials of the wheat germ oil, the processing temperature, excessive added reagent amount and the like, some odorous substances in the obtained crude oil are not completely removed, so that the quality of the wheat germ oil is influenced.

The deodorization is a technological process for removing the odor substances by steam distillation under the conditions of high temperature and high vacuum, and the deodorization can not only remove the odor substances in the oil, improve the smoke point of the oil and the flavor of the oil, but also remove peroxides and decomposition products thereof. The crude oil deodorization process can make unsaturated fatty acid in the oil produce isomerization reaction to produce trans-fatty acid, so as to increase the content of trans-fatty acid in the vegetable oil. However, the traditional wheat germ oil deodorization equipment has the defects that the treatment time is too long, or the oil temperature is too high, and researches show that the higher the oil temperature is, the more trans-fatty acid is increased; the longer the deodorization time, the more trans fatty acids increase.
