Method for extracting taxus chinensis essential oil from taxus chinensis seeds

Abstract

The invention relates to a method for extracting taxus chinensis essential oil from taxus chinensis seeds. The method comprises the following steps: S10, peeling the taxus chinensis seeds; S20, subjecting the taxus chinensis seeds to primary drying treatment, and controlling the moisture in the taxus chinensis seeds subjected to the primary drying to be 15%-20%; S30, grinding the taxus chinensis seeds until the taxus chinensis seeds are cracked and / or crushed; S40, subjecting the taxus chinensis seeds to secondary drying treatment, and controlling the water temperature in the taxus chinensis seeds subjected to the secondary drying to be 1%-8%; S50, stir-frying the taxus chinensis seeds; S60, performing oil squeezing treatment on the taxus chinensis seeds; and S70, standing the squeezed taxus chinensis seed oil, and canning the supernatant obtained after the standing so as to complete preparation and canning of the taxus chinensis seed oil.

Description

technical field [0001] The invention relates to a method for extracting yew essential oil from yew seeds. Background technique [0002] In the prior art, the following process is usually used to prepare yew rapeseed oil: [0003] Step 1: Dehulling the yew seeds. [0004] Step 2: drying the dehulled yew seeds in an exposed environment to remove their moisture. [0005] Step 3: put the dried yew seeds into the frying equipment to fry the yew seeds. [0006] Step 4: Put the roasted yew seeds into an oil press to extract yew seed oil. [0007] Step 5: The yew seed oil is left to stand, and then separated to obtain clarified yew seed oil. [0008] The above-mentioned preparation process in the prior art has the following defects: [0009] 1. The natural drying method is used to remove the moisture in the yew seeds for too long. [0010] 2. The method of natural drying cannot remove the moisture in the central area of ​​the yew seeds to the greatest extent, which not only ne...

AI Technical Summary

Problems solved by technology

[0009] 1. The natural drying method is used to remove the moisture in the yew seeds for too long

[0010] 2. The natural drying method cannot remove the moisture in the central area of ​​the yew seeds to the greatest extent, which not only needs to increase the frying time, but also causes the yew seeds to "pop" due to the large internal moisture during frying

[0011] 3. In order to control the quality of yew seed oil, the frying time should not be too long, which leads to the incomplete removal of the internal level of the yew seeds after frying, and the yew seeds with a certain amount of moisture cannot be maximized in the oil extraction process. get oil yield
