【摘要】：目的采用氣相色譜法測(cè)定沙棘籽油中甾醇含量,考察低甾醇沙棘籽油(sea buckthorn seed oil,SBSO)的制備工藝。方法采用皂化萃取法、絡(luò)合法、脫膠堿煉法和吸附法分別制備低甾醇沙棘籽油,以注射用大豆油中甾醇含量為對(duì)照,通過(guò)氣相色譜法對(duì)沙棘籽油中甾醇含量進(jìn)行檢測(cè)。結(jié)果硅膠吸附法制備的低甾醇沙棘籽油總甾醇含量顯著降低,與沙棘籽毛油相比,占總甾醇90%左右的β-谷甾醇由19.56%降至6.31%。皂化萃取法、絡(luò)合法、脫膠堿煉制備的低甾醇沙棘籽油甾醇含量均有不同程度的降低,β-谷甾醇含量分別為13.46%、8.22%和9.36%。結(jié)論硅膠吸附法精制的沙棘籽油總甾醇含量顯著降低,該制備工藝操作相對(duì)簡(jiǎn)易,除雜效率高。
[Abstract]:Objective to establish a GC method for determination of sterol content in seabuckthorn seed oil of seabuckthorn seed oil, low sterol (sea buckthorn seed oil, SBSO) in the preparation process. Using the method of saponification and extraction method, complex method, were prepared with low alkali refining sterols of seabuckthorn seed oil degumming method and adsorption method, the injection of sterol content in soybean oil for the control, detection of sterol content in seabuckthorn seed oil by gas chromatography. The total sterol content low sterol seabuckthorn seed oil prepared by silica gel adsorption decreased significantly, compared with the sea buckthorn seed oil, accounting for about 90% of the total sterol beta sitosterol from 19.56% to 6.31%. saponification and extraction method, complexation, reduction of alkali refining degumming preparation of low sterol sterol content of seabuckthorn seed oil in varying degrees, sitosterol content were 13.46%, 8.22% and 9.36%. conclusion silica gel adsorption refining of seabuckthorn seed oil total sterol content decreased significantly, the preparation process. It is relatively simple, with high removal efficiency.
