Embodiment 1

[0022] Firstly, the shelled hemp seeds are put into a constant temperature drying box, dried at 50° C. for 12 hours, and then the dried hemp seeds are put into a pulverizer to be pulverized into hemp seeds powder. Weigh 20.1g of hemp seed powder into a stoppered Erlenmeyer flask, add 100mL of 25wt% ethanol solution to soak for 2 hours, and adjust the ultrasonic power to 240W for 20 minutes in a water bath at a temperature of 25°C, then place the mixture at room temperature and centrifuge , get the upper layer oily liquid to obtain hemp seed oil.

[0023] The obtained hemp seed oil is a yellow-green clear transparent liquid, and the measured hemp seed oil extraction rate is 19.78%.

Embodiment 2

[0025] Firstly, the shelled hemp seeds are put into a constant temperature drying box, dried at 60° C. for 10 hours, and then the dried hemp seeds are put into a pulverizer to be pulverized into hemp seeds powder. Weigh 20.0g of hemp seed powder into a stoppered Erlenmeyer flask, add 200mL of 50wt% ethanol solution to soak for 3h, and adjust the ultrasonic power to 180W for 30min in a water bath at a temperature of 40°C, then place the mixture at room temperature and centrifuge , get the upper layer oily liquid to obtain hemp seed oil.

[0026] The obtained hemp seed oil is a yellow-green clear transparent liquid, and the measured hemp seed oil extraction rate is 20.15%.

Embodiment 3

[0028] Firstly, the shelled hemp seeds are put into a constant temperature drying box, dried at 70° C. for 9 hours, and then the dried hemp seeds are put into a pulverizer to be pulverized into hemp seeds powder. Weigh 20.0g of hemp seed powder into a stoppered Erlenmeyer flask, add 200mL of 75wt% ethanol solution to soak for 1h, and adjust the ultrasonic power to 130W for 20min in a water bath at a temperature of 50°C, place the mixture at room temperature, and centrifuge , get the upper layer oily liquid to obtain hemp seed oil.

[0029] The obtained hemp seed oil is a yellow-green clear transparent liquid, and the measured hemp seed oil extraction rate is 18.42%.

Abstract

The invention discloses fructus cannabis oil and a water extraction method thereof. The method comprises the following steps: dehydrating unshelled fructus cannabis at a constant temperature and drying the fructus cannabis until the weight of the fructus cannabis is constant; crushing the fructus cannabis, soaking the crushed fructus cannabis in a solution, performing ultrasonic extraction on a mixed solution obtained by soaking, performing centrifugal separation, taking a supernatant, and conducting canning to obtain the fructus cannabis oil. Compared with a common method, the process has the advantages that the oil yield is increased, the resource utilization rate is increased, and the active ingredients of the fructus cannabis oil are protected; and meanwhile, the whole process is simple, an organic solvent difficult to treat is not introduced, and the high-quality hemp seed oil rich in unsaturated fatty acid is obtained.

Description

technical field [0001] The invention relates to hemp seed oil and a water-substituting leaching extraction method thereof, belonging to the technical field of vegetable oil extraction. Background technique [0002] Hemp seed is the dry and mature seed of Cannabis genus Moraceae. It is widely distributed in all parts of my country, mainly concentrated in North China, South China, Northeast China and other places. effect. The content of fatty acids in hemp seeds is 25% to 45%, the content of protein is 20% to 25%, including 8 kinds of essential amino acids for human physiological metabolism, and the content of carbohydrates is about 10% to 20%. In addition to being rich in protein, oil, cellulose and vitamins, hemp seeds also contain minerals, polyphenolic compounds, pigments and volatile oils required by the human body. These ingredients have anti-inflammatory, blood pressure, blood lipid, diuretic, The effects of treating constipation, improving memory and anti-oxidation ar...
