Embodiment 1

[0020]Embodiment 1: Take an appropriate amount of dried bitter melon seeds, remove the outer shell of the bitter melon seeds with a sheller to obtain bitter melon seeds, remove impurities, wash, dry at room temperature, and pulverize to obtain bitter melon seed powder greater than 40 mesh. Turn on the power of the supercritical extraction equipment, turn on the cold cycle switch and the heating switch, set the temperature of the extraction cylinder to 32°C, the temperature of the separation cylinder I to 50°C, and the temperature of the separation cylinder II to 40°C, and crush the bitter melon seeds Pour the powder into the barrel and put it into the extraction cylinder, start the carbon dioxide circulation system, adjust the pressure of the extraction cylinder to 35MPa, the pressure of the separation cylinder I to 5.5MPa, the pressure of the separation cylinder II to 4.0MPa, the cylinder to be extracted, the separation cylinder (I , II) When the temperature and pressure reach...

Embodiment 2

[0021] Example 2: Take an appropriate amount of dry bitter melon seeds, remove the outer shell of the bitter melon seeds to obtain bitter melon seeds, remove impurities, wash, dry at room temperature, freeze and pulverize below 30°C, and obtain bitter melon seed powder larger than 40 meshes. Turn on the power of the supercritical extraction equipment, turn on the cold cycle switch and the heating switch, set the temperature of the extraction cylinder to 36°C, the temperature of the separation cylinder I to 55°C, and the temperature of the separation cylinder II to 45°C, and crush the bitter melon seeds Pour the powder into the barrel and put it into the extraction cylinder, start the carbon dioxide circulation system, adjust the pressure of the extraction cylinder to 38MPa, the pressure of the separation cylinder I to 5.0MPa, the pressure of the separation cylinder II to 5.0MPa, the cylinder to be extracted, the separation cylinder (I , II) When the temperature and pressure rea...

Embodiment 3

[0022] Example 3: Take an appropriate amount of dry bitter melon seeds, remove the shell of the bitter melon seeds to obtain bitter melon seeds, remove impurities, wash, dry at room temperature, freeze and pulverize below 30°C, and obtain bitter melon seed powder larger than 40 meshes. Turn on the power of the supercritical extraction equipment, turn on the cold cycle switch and the heating switch, set the temperature of the extraction cylinder to 40°C, the temperature of the separation cylinder I to 53°C, and the temperature of the separation cylinder II to 42°C, and crush the bitter melon seeds Pour the powder into the barrel and put it into the extraction cylinder, start the carbon dioxide circulation system, adjust the pressure of the extraction cylinder to 40MPa, the pressure of the separation cylinder I to 6.0MPa, the pressure of the separation cylinder II to 4.5MPa, the cylinder to be extracted, the separation cylinder (I , II) When the temperature and pressure reach the...

Abstract

The invention discloses a method for supercritical extraction of balsam pear oil using carbon dioxide, which is aimed at solving the problems of solvent recovery and solvent residual for the conventional solvent method employed in balsam pear oil extraction. The method for supercritical extraction of balsam pear oil can be carried out at normal temperature.

Description

technical field [0001] The invention relates to a method for extracting active ingredients from plant seeds or kernels, in particular to a method for extracting bitter melon oil from bitter melon seeds. Background technique [0002] Bitter gourd (monordica charantia L.), also known as bitter gourd, golden litchi, mangy gourd, etc., is an annual vine herb of the family Cucurbitaceae. Native to India, widely distributed in tropical, subtropical and temperate regions. It was introduced to Yunnan and other places in my country during the Southern Song Dynasty, and it was not eaten by southerners until the middle and late Ming Dynasty. It is still cultivated in South China. In recent years, it has been gradually cultivated and widely eaten in northern regions. Bitter gourd has crisp and tender flesh and moderate bitterness. It has the highest content of vitamin C in melons. In recent years, as the pharmacological effects of bitter gourd on immunity, anti-tumor, antibacterial, h...
