Embodiment 1

[0037] As a raw material derived from barley, barley bran containing the barley skin discharged during the whitening process of Hokkaido-grown Ryofu, which is barley for brewing, is used. The heat-extraction treatment accompanied by pressurization was performed by an accelerated solvent extraction (ASE) method. In this high-speed solvent extraction method, a Dionex high-speed solvent extraction apparatus ASE-200 (manufactured by Dionex Corporation) was used as an extraction device. Specifically, 150 g of barley bran containing barley skin is loaded into 10 stainless steel tubes (cell) with a capacity of 22 ml, a solvent mixed with hexane and isopropanol at a volume ratio of 3:2 is added, and placed at a high speed. extraction device. Then, under the conditions that the oven temperature is 125°C, the oven temperature rise time is 6 minutes, the set temperature / pressure rest time is 25 minutes, the flushing volume is 60%, the nitrogen purging time is 60 seconds, and the rest cy...

Embodiment 2

[0040] As a raw material derived from barley, barley bran containing the barley skin discharged during the whitening process of Ryofu produced in Hokkaido, which is barley for brewing, is used. The same Dionex high-speed solvent extraction apparatus ASE-200 (manufactured by Dionex) as in Example 1 above was used. Specifically, 150 g of barley bran containing barley skin was loaded into 10 stainless steel tubes with a capacity of 22 ml, a solvent mixed with hexane and isopropanol at a volume ratio of 3:2 was added, and placed in a high-speed extraction device. Then, under the conditions that the oven temperature is 155°C, the oven temperature rise time is 6 minutes, the set temperature / pressure rest time is 45 minutes, the flushing volume is 60%, the nitrogen purging time is 60 seconds, and the rest cycle is 2 times Heat extraction treatment is carried out. The extract liquid obtained by the heat extraction treatment was collected and concentrated under reduced pressure in an ...

Embodiment 3

[0042] As a barley-derived raw material, barley bran of Ryofu from Hokkaido, which is barley for brewing, was used, and 145 g of the above-mentioned barley bran was put into 10 stainless steel tubes with a capacity of 22 ml, and hexane and isopropanol were added at a volume ratio of 3 : 2 mixed solvent, placed in the Dionex high-speed solvent extraction device ASE-200 (manufactured by Dionex). Then, under the conditions that the oven temperature is 100°C, the oven temperature rise time is 6 minutes, the set temperature / pressure rest time is 15 minutes, the flushing volume is 60%, the nitrogen purging time is 60 seconds, and the rest cycle is 2 times Heat extraction treatment is carried out. The extract liquid obtained by the heat extraction treatment was collected and concentrated under reduced pressure in an evaporator to obtain 24.5 g of viscous vegetal glycosphingolipid-containing barley oil of yellowish brown.

Abstract

A method for efficiently manufacturing a vegetable glycosphingolipid having reduced unpleasant odor using a barley-derived starting material is provided. The method for manufacturing a vegetable glycosphingolipid according to the present invention comprises an extraction step (2) for preparing a mixture with a non-halogenated alcohol-based solvent and heating the starting material mixture, and a fatty acid removal step (3) for removing fatty acids from the extract obtained in the extraction step (2).

Description

technical field [0001] The present invention relates to a method for producing vegetable oils containing glycosphingolipids from barley-derived raw materials. Background technique [0002] Animal oil or vegetable oil has been used in many aspects such as food, cosmetics and medicine since ancient times. That is, these animal and vegetable oils are used to improve the physical properties of food or cosmetics, or as solvents and dispersants for food or cosmetics, etc., by utilizing their unique physical properties of showing high-viscosity liquid properties at room temperature. [0003] In recent years, applications of glycosphingolipids contained in the aforementioned animal and vegetable oils to foods and cosmetics have attracted attention. For example, ceramides contained in glycosphingolipids (usually having a structure obtained by amide bonding of a sphingosine base with a long-chain aminopolyol structure and a long-chain fatty acid) and cerebrosides (having a structure ...
