Embodiment 1

[0035] 200nm particle size in raw material tank 7, water content 10%, highland barley bran powder 60g (about 200ml) of impurity content 0.2% is put into extraction tank 6, and volume is 1L, and cosolvent water 2g is added extraction tank 6, then The extraction tank was preheated to 35°C. The main solvent carbon dioxide is liquefied from the storage tank 1 to the liquefier 2, and enters the preheater 4 through the high-pressure pump 3. The preheating temperature of the main solvent is the same as that of the extraction tank. After preheating, it enters the extraction tank 6 and is mixed with barley bran powder. Extract together with the co-solvent, the flow rate is controlled at 5L / h, the initial pressure is 80B as the main solvent, and then the pressure of the extraction tank is increased to 260B of the critical pressure. The temperature of the separator and the product storage tank are both 32°C. The pressure of the separator 8 is constant at 220 Bar, and the pressure of the ...

Embodiment 2

[0037] Put the highland barley bran powder 60g (about 200ml) with a particle size of 600nm in the raw material tank 7, a water content of 0.001%, and an impurity content of 3% into the extraction tank 6, with a volume of 1L, and add the cosolvent isododecane 100g into the extraction tank 6 , and then preheat the extraction tank to 80°C. The main solvent carbon dioxide is liquefied from the storage tank 1 to the liquefier 2, and enters the preheater 4 through the high-pressure pump 3. The preheating temperature of the main solvent is the same as that of the extraction tank. After preheating, it enters the extraction tank 6 and is mixed with barley bran powder. Extract together with the co-solvent, the flow rate is controlled at 60L / h, the initial pressure is 90B as the main solvent, and then the pressure of the extraction tank is increased to 200B of the critical pressure, and the temperature of the separator and the product storage tank are both 40°C. The pressure of the separ...

Embodiment 3

[0039] Put 4mm particle size in raw material tank 7, water content 5%, highland barley bran powder 60g (about 200ml) of impurity content 2% into extraction tank 6, volume is 1L, add co-solvent ethyl acetate 20g into extraction tank 6, The extraction tank was then preheated to 65°C. The main solvent ethylene is liquefied from the storage tank 1 to the liquefier 2, and enters the preheater 4 through the high-pressure pump 3. The preheating temperature of the main solvent is the same as that of the extraction tank. After preheating, it enters the extraction tank 6 and is mixed with the barley bran powder. Extract with the co-solvent, the flow rate is controlled at 38L / h, the pressure at the beginning is 30B as the main solvent, and then the pressure of the extraction tank is increased to 90B of the critical pressure. The temperature of the separator and the product storage tank are both 42°C. The pressure of separator 8 was constant at 50Bar, and the pressure of separator 9 was i...

Abstract

The invention provides essential oil extracted from highland barley bran and a processing method thereof. The processing method comprises the steps of selecting highland barley bran, removing impurities, pulverizing, drying, performing supercritical extraction, etc. The inventive essential oil mainly contains fatty acid such as palmitic acid, oleic acid and linoleic acid; and has over 80% of unsaturated fatty acid and over 45% of oleic acid. The essential oil also contains vitamin E, vitamin B group, ceramide, superoxide dismutase (SOD), and essential minerals such as magnesium, phosphate, potassium, zinc, ferrum, manganese, copper, selenium and chromium. The inventive essential oil has the effects of reducing low-density lipoprotein (LDL) cholesterol but not HDL cholesterol, preventing arteriosclerosis, lowering blood pressure, and preventing cardiovascular and cerebrovascular diseases; and can be directly used in the fields of food, health products, pharmaceuticals and cosmetics.

Description

technical field [0001] The invention relates to a highland barley essential oil and an extraction method thereof, in particular to a preparation method of highland barley bran essential oil and supercritical extraction thereof. Background technique [0002] At present, there are many studies on highland barley bran at home and abroad, but most of them focus on functional ingredients such as glucan and polypeptide. In the current literature, including laboratory research, there are almost no literature reports on highland barley bran oil, let alone the development of highland barley bran. The production process of leather oil. The amount of information obtained by searching for "highland barley bran oil" or "highland barley bran essential oil" on Baidu and Google websites is zero. [0003] From our company's preliminary research and development, the highland barley bran oil has the following properties: [0004] The main fatty acids contained in highland barley bran oil are...
