Abstract

The invention discloses a preparation method of krill-flavor plant blend oil rich in phospholipid. The method comprises the steps of uniformly mixing antarctic krill powder and vegetable oil accordingto the weight ratio of 1:(0.1-1) to obtain a mixture; extracting the mixture through supercritical CO2, wherein the temperature of an extraction kettle is 30-55 DEG C, the pressure of the extractionkettle is 20-35 MPa, the temperature of a first separation kettle is 35-55 DEG C, the pressure of the first separation kettle is 5-15 MPa, the temperature of a second separation kettle is 30-40 DEG C,the pressure of the second separation kettle is 3-10 MPa, and the extraction time is 30-120 minutes; obtaining the krill-flavor plant blend oil rich in phospholipid from the first separation kettle.According to the blend oil prepared by means of the method, the content of the phospholipid is obviously increased, and a soft krill flavor is obtained; meanwhile, the peculiar smell of krill and vegetable oil is removed, the nutritional value and commercial value of finished oil are increased, the phospholipid in the blend oil is pure natural, the absorption and utilization of the phospholipid bythe human body are facilitated, and the nutritional value of the blend oil is further increased.

Description

technical field [0001] The invention relates to an edible blending oil, in particular to a preparation method of a krill-flavored vegetable blending oil rich in phospholipids. Background technique [0002] In recent years, blended oils have become a popular trend in the edible oil industry due to their unique organoleptic properties. Traditionally, blending oils are prepared by directly mixing various finished oils in proportion. In theory, it seems easy to balance various components, but these ignore the problem of whether the oil can be mixed evenly. If the mixing is not uniform, It is very likely that the composition ratio of the oil poured out of the same bottle at different times is very different, thus losing the purpose of true balance. At the same time, due to the relatively large differences in the oil yield and component content of various oils, it is very difficult to directly mix the raw materials to prepare this kind of oil with a balanced ratio, and the proble...
