Problems solved by technology

Lemongrass essential oil is often extracted by open steam distillation, supercritical, etc. The steam distillation extraction temperature is high, and the volatile components obtained have a low boiling point and have a cooking smell. The product obtained by supercritical extraction contains a large amount of lipid wax components , the product state and flavor are not good, and it is not convenient to use

Embodiment 1

[0020] (1) Preparation of lemongrass crude oil: Grind lemongrass, add 20 times the mass of water, mix well and add to the extraction kettle, and heat the extraction kettle until the liquid temperature in the kettle reaches 55°C, then turn on the vacuum pump to make the extraction kettle Form a vacuum state, the degree of vacuum is subject to the boiling of the body fluid in the extraction kettle, then close the passage between the extraction kettle and the vacuum pump, and make the extraction kettle, condenser, buffer tank, pervaporation system and cold trap form a passage, and start pervaporation Ginkgo biloba essential oil is roughly extracted, and the permeate collected in the cold trap is lemongrass crude oil; the pervaporation uses a PDMS organosilicon composite membrane for separation operation;

[0021] (2) Prepare the water phase: take 2 parts of decaglycerol monooleate, dissolve it in 80 parts of glycerin at 40°C, stir and dissolve evenly, then add 8 parts of deionized...

Embodiment 2

[0024] (1) Preparation of lemongrass crude oil: Grind lemongrass, add 100 times the mass of water, mix well and add to the extraction kettle, and heat the extraction kettle until the liquid temperature in the kettle reaches 65°C, then turn on the vacuum pump to make the extraction kettle Form a vacuum state, the degree of vacuum is subject to the boiling of the body fluid in the extraction kettle, then close the passage between the extraction kettle and the vacuum pump, and make the extraction kettle, condenser, buffer tank, pervaporation system and cold trap form a passage, and start pervaporation Ginkgo biloba essential oil is roughly extracted, and the permeate collected in the cold trap is lemongrass crude oil; the pervaporation uses a PDMS organosilicon composite membrane for separation operation;

[0025] (2) Prepare the water phase: take 4 parts of octaglycerol monostearate, dissolve in 60 parts of sorbitol at 60°C, stir and dissolve evenly, then add 12 parts of deionize...

Embodiment 3

[0028] (1) Preparation of lemongrass crude oil: Grind lemongrass, add 60 times the mass of water, mix well and add to the extraction kettle, and heat the extraction kettle until the liquid temperature in the kettle reaches 60°C, then turn on the vacuum pump to make the extraction kettle Form a vacuum state, the degree of vacuum is subject to the boiling of the body fluid in the extraction kettle, then close the passage between the extraction kettle and the vacuum pump, and make the extraction kettle, condenser, buffer tank, pervaporation system and cold trap form a passage, and start pervaporation Ginkgo biloba essential oil is roughly extracted, and the permeate collected in the cold trap is lemongrass crude oil; the pervaporation uses a PDMS organosilicon composite membrane for separation operation;

[0029] (2) Prepare the water phase: take 3 parts of decaglycerol palmitate, dissolve it in 70 parts of glycerin at 50°C, stir and dissolve evenly, then add 10 parts of deionized...

Abstract

The invention discloses lemon grass essential oil emulsion and a preparation method thereof. The preparation method of the lemon grass essential oil emulsion comprises the following steps: performing coarse extraction on lemon grass to obtain a mixed penetrating fluid which contains an oil phase and a water phase; then, adding an emulsifying agent to perform shear emulsification, and preparing and obtaining the uniform and stable lemon grass essential oil emulsion. The less grass essential oil emulsion disclosed by the invention is water-soluble; moreover, the flavour is fresh, a warmed-over flavour is avoided, and the flavour is rich and real; the lemon grass essential oil emulsion disclosed by the invention is stable, has the self-stabilizing capacity, can be applied to various beverage systems, including a neutral beverage, an acid beverage, a high-sugar beverage, particularly, a carbonated beverage, can keep stable, can avoid demulsification, and can also prevent the beverage into which a fat-soluble component is added from generating floating oil; the lemon grass essential oil emulsion can be applied to a washing product, and can promote the degreasing capacity besides providing fresh lemon flavour; particularly, when the lemon grass essential oil emulsion is applied to the products, such as a dishwashing liquid, liquid soap, a laundry detergent and the like, the degreasing capacity can be improved by 10 percent; the lemon grass essential oil emulsion can be applied to cosmetics, such as facial cleansers and facial masks.

Description

technical field [0001] The invention relates to a method for preparing an additive, in particular to a method for preparing a lemongrass essential oil emulsion. Background technique [0002] Lemongrass is the fresh or dry whole grass of the genus Lemongrass of the grass family Citronella. The scientific name is Citronella, also known as Lemongrass, Lemongrass. Lemongrass has a strong lemon fragrance and can replace lemon as an important spice to a certain extent.
