Embodiment 1

[0021] The present embodiment provides a method for extracting high-purity Cyperus root oil, comprising the following steps:

[0022] S1. Pretreatment of the rhizomes of the sedge. After the rhizomes of the harvested sedge are cleaned and the roots are removed, they are naturally sun-dried or dried for 1-20 days, and the water content is reduced to 12%;

[0023] S2. Broken, dried or dried sedge rhizomes are broken into 4-9 mesh particles through a crusher, which is 5 mesh in the present embodiment;

[0024] S3. Cold pressing, putting the crushed raw materials into a hydraulic oil press for pressing with a pressing pressure of 15 MPa, a pressing temperature of 35° C., and a pressing time of 2 hours to obtain primary oil.

[0025] S4. After standing for 2-4 hours, separate the sedge root oil from the upper layer.

Abstract

The invention discloses high-purity cyperus esculentus root oil and an extraction method thereof. The extraction method comprises the following steps: S1, taking rootstock parts of harvested cyperus esculentus, conducting cleaning, and conducting natural drying in the sun or drying; and S2, extracting primary oil from the air-dried or dried rootsthock parts in a cold pressing and cold extracting manner to prepare the cyperus esculentus root oil finished product. The essence in the cyperus esculentus root oil is extracted by adopting a low-temperature cold pressing and cold extraction method, no chemical substance residue exists, the purity is high, and the cyperus esculentus root oil can be widely applied to cosmetics and has good market prospects and economic values.

Description

technical field [0001] The invention relates to the technical field of vegetable oil processing, in particular to a high-purity sedge root oil and an extraction method thereof.
