Abstract

The invention discloses a supercritical CO2 extracting almond oil technology that adopts supercritical extracting device, which includes CO2 gas holder, purifier, refrigeration system, high pressure pump, extracting kettle, and circulating system. The process includes the following steps: smashing the almond, filtering, adding to extracting kettle, taking pressurization, when reaching 20MPa-45MPa, adjusting the pressure and the flux of CO2 at 12L / h-28L / h, keeping the temperature and pressure, extracting for 1h-4h, collecting the extract every 30min, weighting, calculating the oil tapping ratio. The method lays the foundation for almond oil industry producing.

Description

technical field [0001] The present invention relates to a kind of extraction technology of grease, particularly a kind of supercritical CO 2 Almond oil extraction process. Background technique [0002] Bitter almonds are rich in fatty oils, which contain a large amount of oleic acid and linoleic acid, which have important physiological effects and medicinal value on the human body; almond oil is a non-drying oil, which remains clear at -10°C, It can be solidified when it is dry, and it has great application value in nutritional food, medicine and light industry. of cooking oil. [0003] At present, the industrial production of almond oil is mostly extracted by maceration and cold pressing. Product color is not ideal; supercritical CO 2 Extraction has the advantages of low operating temperature, strong dissolving ability, non-toxic, non-polluting, no solvent residue and easy separation of products; it overcomes the shortcomings of solvent extractio...
