Abstract

The invention relates to the field of essence preparation and concretely relates to a lemongrass essence extraction method. The method comprises carrying out supercritical CO2 extraction on lemongrass 3-5 times under conditions of extraction pressure of 35-50MPa, an extraction temperature of 25-55 DETG C, a separation temperature of 65-70 DEG C and each-process extraction time of 30-40min. The method has simple processes, can be operated conveniently and can satisfy industrial large-scale production requirements. The product is powder, has high purity and quality and less impurities and can be easily packaged and preserved. The method utilizes a short time static state mode to realize multitime extraction. Compared with the existing extraction method, the lemongrass essence extraction method realizes short time consumption, high extraction efficiency, low energy consumption and a low production cost.

Description

technical field [0001] The invention relates to the field of essence preparation, in particular to a method for extracting essence from citronella grass. Background technique [0002] Lemongrass is a kind of thatch spice that grows in the subtropical zone. Lemongrass itself exudes a natural and strong lemon fragrance, which has the special effect of ventilating the stomach, refreshing the mind and aphrodisiac. It has antibacterial ability and can treat cholera, acute gastroenteritis and chronic diarrhea. It moisturizes the skin and helps women to maintain beauty. It contains a lot of vitamin C and is also a good product for beauty and hairdressing. Regulates oil secretion, good for oily skin and hair, can be added to water to clean skin and promote blood circulation. [0003] The methods for extracting essence from citronella grass generally include steam distillation, pressing, and solvent extraction. These methods are simple in equipment, easy to operate, and low in cost;...
