The invention belongs to the technical field of fat or
grease oil refining, and discloses a production method of functional
walnut oil rich in biological organic
selenium. The production method comprises the following steps: selecting
mildew-free walnuts, removing shells of the walnuts by using a shell removing
machine, conveying obtained walnut kernels with shells to a walnut kernel
skin removingmachine to remove walnut kernel skins, and producing qualified high-quality refined
walnut oil by using high-tech physical
walnut oil squeezing equipment and high-tech physical refined oil refining equipment; under a sterile condition, adding biological organic
selenium or biological nano-
selenium into the refined oil in a 55-75 DEG
C constant-temperature heating stirrer, and uniformly stirring;and bottling by using a filling
machine, filling
nitrogen and sealing to form the functional walnut oil rich in biological organic selenium. The qualified high-quality refined walnut oil is obtained,the taste and quality of the walnut oil are remarkably improved, and the
impurity content of the walnut oil is greatly reduced; meanwhile, biological organic selenium or biological nano-selenium is added to form a new organic-selenium-rich functional walnut oil commodity which has market requirements and is beneficial to
human health, and the quality and additional value of the walnut oil are improved.
