preparation example Construction

[0034] A preparation method of hemp essential oil, the process route is as follows figure 1 Shown, described method is prepared by following process:

[0035] (1) Hemp seed is dried at low temperature (controlling moisture content 5%-20%), pulverized, and sieved (10-60 mesh);

[0036] (2) Put the sieved powder into the extraction kettle, check the air tightness of the instrument; turn on the supercritical cooling device, and when the temperature drops below 5 degrees, set the extraction carbon dioxide temperature (30-50°C), and open the When the heating switch reaches the set temperature value, gradually adjust the extraction pressure to the specified value (25-45MPa). When the pressure rises to the specified value, open the valve of the collection bottle and adjust the extraction CO 2 Flow rate (4-8L / min), and start to record the extraction time (1-4h), until the extraction is completed;

[0037] (3) The hemp oil after supercritical is decolorized with activated clay (decol...

[0041] A preparation method of hemp essential oil, comprising the steps of:

[0042] (1) Hemp seed pretreatment: place the hemp seed in an environment of 60° C. and dry until the water content is 10%, pulverize, pass through a 20-mesh sieve, and obtain hemp seed powder;

[0043] (2) Extraction: put the hemp seed powder into the extraction kettle, turn on the supercritical cooling device, and when the temperature drops below 5°C, set the extraction CO 2 The temperature is 39.32°C, and the heating switch is turned on. When the set temperature value (39.32°C) is reached, the extraction pressure is gradually adjusted to 36.6MPa. When the pressure rises to the specified value (36.6MPa), the valve of the collection bottle is opened to adjust the extraction CO 2 The flow rate was 7.02L / min, and the extraction time was recorded, and the extraction was finished after 3.5h to obtain hemp oil;

[0044] (3) decolouring: the hemp oil after extraction is decolorized with active clay, the d...

[0048] A preparation method of hemp essential oil, comprising the steps of:

[0049] (1) hemp seed pretreatment: place the hemp seed in an environment of 55° C. and dry until the water content is 15%, pulverize, pass through a 30-mesh sieve, and obtain hemp seed powder;

[0050] (2) Extraction: put the hemp seed powder into the extraction kettle, turn on the supercritical cooling device, and when the temperature drops below 5°C, set the extraction CO 2 The temperature is 32°C, and the heating switch is turned on. When the set temperature is reached, the extraction pressure is gradually adjusted to 40MPa. When the pressure rises to the specified value, the valve of the collection bottle is opened, and the extraction CO is adjusted. 2 The flow rate is 6L / min, and the extraction time is recorded, and the extraction ends after 2 hours to obtain hemp oil;

[0051] (3) decolorization: the hemp oil after extraction is decolorized with activated clay, the decolorization time is 20min...

Abstract

The invention discloses a preparation method and application of hemp essential oil, belonging to the technical field of hemp deep processing. The preparation method comprises the following steps: (1) hemp seed pretreatment: drying the hemp seed, crushing and sieving to obtain the hemp seed powder; (2) extraction: putting the hemp seed powder into an extraction kettle, Carry out supercritical extraction of carbon dioxide to obtain hemp oil; (3) decolorization: decolorize with activated clay; (4) deacidify: use alkaline clay for deacidification; (5) purification: use molecular distillation to purify to obtain hemp essential oil. The preparation method of the invention can solve the problems that the hemp oil prepared by the traditional method has many impurities, deep color, low oil yield, loss of natural flavor, poor stability and the like. The hemp essential oil prepared by the invention has good stability and can be added to cosmetics for use.

Description

technical field [0001] The invention relates to the technical field of hemp processing, in particular to a preparation method and application of hemp essential oil. Background technique [0002] Hemp seed, also known as hemp seed, hemp seed, hemp seed, pock seed kernel, etc., is the dried mature fruit of the moraceae plant hemp or the seed kernel with the peel removed. It is sweet, flat, and returns to the spleen, stomach, and large intestine meridian. , Runchang, Tonglin, blood circulation. Hemp seed is rich in protein. Hemp seed protein can improve nutrition, regulate blood sugar, promote brain tissue germination, enhance the body's anti-fatigue and immune function, and have a certain anti-aging effect. Various essential amino acids, so it has very rich nutritional value and can be used as an ideal protein resource in the food industry. Hemp seed is rich in oil. Hemp seed oil has the effects of lowering blood pressure, diuresis, syringe, anti-inflammation, anti-thrombosi...
