Abstract

The invention relates to the technical field of sea buckthorn, in particular to sea buckthorn seed oil and a preparing method thereof. The sea buckthorn seed oil is obtained according to the following preparing method, and the preparing method comprises the first step of carrying out CO2 extraction on raw sea buckthorn seed oil for 1.5h-2.5h through supercritical / subcritical equipment in a temperature of 38 DEG C to 42 DEG C under a pressure of 18MPa to 22MPa and obtaining extractive matter after extraction and the second step of obtaining the sea buckthorn seed oil after the extractive matter is primarily separated and secondarily separated. Compared with a traditional solvent extraction method, the preparing method is low in energy consumption and short in extracting time. Meanwhile, the linolenic acid content and the linoleic acid content in the obtained sea buckthorn seed oil are greatly improved, the content of moisture and volatile is greatly reduced, and residual organic solvent is avoided. Thus, the sea buckthorn seed oil completely meets a quality standard of 'sea buckthorn seed oil' of national water conservancy industry SL 493-2010, and the quality of the sea buckthorn seed oil is greatly improved.

Description

technical field [0001] The invention relates to the technical field of seabuckthorn, and relates to seabuckthorn seed oil and a preparation method thereof. Background technique [0002] Seabuckthorn is a deciduous shrub or small tree belonging to the genus Hippophaeaceae. It has strong adaptability to various complex climate conditions and soil conditions, and has strong reproductive ability. After five or six years of planting, it can gradually form a dense forest. Grass community with a coverage of over 80%. The ecological benefits of seabuckthorn are very obvious. It has a very significant effect on soil improvement, water and soil conservation, windbreak and sand fixation, and can promote the development of biodiversity. With the improvement of our country's awareness of ecological environment protection, seabuckthorn, as one of the main tree species for water and soil conservation, has been developed as an ecological industry in some areas. The development and utiliza...
