Embodiment 1

[0027] A kind of extraction process of perilla oil, comprises the following steps:

[0028] (1) The perilla leaves are crushed at a low temperature at -50°C, and the particle size after crushing is 30 mesh, and the perilla powder is obtained, wherein the moisture content of the perilla leaves is 7%;

[0029] (2) Put the perilla powder in the extraction kettle, add 2 times the weight of the extraction agent soybean oil, soak for 30 minutes, turn on the vacuum pump, wait until the pressure in the extraction kettle reaches -0.1Mpa, and use the pressure difference between the extraction kettle and the solvent tank to make it The solvent butane in the solvent tank is injected into the extraction kettle. Under the conditions of extraction temperature of 55°C and extraction pressure of 0.9MPa, after extraction for 8 hours, the extract enters the separation tank;

[0030] (3) The extract is separated in the separation tank at a temperature of 55 °C and a pressure of -0.1 MPa for 5 min...

Embodiment 2

[0034] A kind of extraction process of perilla oil, comprises the following steps:

[0035] (1) Perilla leaves were crushed at a low temperature at -70°C, the particle size after crushing was 40 mesh, and perilla powder was obtained, wherein the moisture content of perilla leaves was 9%;

[0036] (2) Put the perilla powder in the extraction kettle, add 3 times the weight of the extraction agent soybean oil, soak for 30 minutes, turn on the vacuum pump, wait until the pressure in the extraction kettle reaches -0.1Mpa, and use the pressure difference between the extraction kettle and the solvent tank to make it The solvent butane in the solvent tank is injected into the extraction kettle. Under the conditions of extraction temperature of 60°C and extraction pressure of 1.0MPa, after extraction for 7 hours, the extract enters the separation tank;

Abstract

The invention discloses an extraction process of perilla oil, which belongs to the technical field of essential oil extraction and comprises the following steps: (1) pulverizing perilla leaves to obtain perilla powder; (2) placing perilla powder in an extraction kettle, adding 2‑5 times the weight of the extractant, extracted with subcritical butane to obtain the extract; (3) the extract was separated to obtain the solvent and perilla mixed oil, the solvent was recycled into the solvent tank, the perilla mixed oil was collected, and the After further processing, perilla oil is obtained. By improving the extraction process, the loss of perilla essential oil is small and the extraction rate is high.

Description

technical field [0001] The invention relates to the technical field of essential oil extraction, in particular to an extraction process of perilla oil. Background technique [0002] Perilla, which is pungent and warm in nature and has the aroma of perilla, is mainly used in medicine and food industry. Among them, perilla oil is also rich in α-linolenic acid, which has significant health care and medicinal effects on the human body. The extraction process of perilla oil in the prior art includes low-temperature pressing process, supercritical fluid extraction process and the like. [0003] Chinese Patent Publication No. CN106135466A discloses a high-efficiency extraction process of perilla oil, which includes the following steps: Step 1: After the perilla seeds are harvested, they are air-dried or dried to make the water content of the seeds lower than 8%; the raw materials are selected and removed, Make the grain cleanliness reach more than 99%; Step 2: Use a double-screw ...
