Problems solved by technology

Although the distillation method is simple and convenient, if the plant raw materials are directly heated, it is easy to decompose some components of the essential oil and coke some raw materials, which will affect the quality of the essential oil; the pressing method is suitable for fresh plant tissues, but the product contains moisture, mucilage, etc., and further research is required. Treatment; supercritical fluid extraction method is widely applicable, but the equipment cost is large, and it is not widely used in my country

Embodiment 1

[0017] A method for extracting essential oil from jackfruit peel as a raw material, the steps are:

[0018] 1) Add water twice its weight to the jackfruit peel from which the white skin layer has been removed, crush and squeeze, separate the liquid and filter to obtain a filtrate;

[0019] 2) Stir and mix 40% β-cyclodextrin, 15% sodium sulfate and the rest of water according to the mass concentration to prepare the extractant;

[0020] 3) When extracting, mix the filtrate and extractant at a ratio of 1:1, let it stand at 30°C for 30 minutes, and take the upper liquid phase;

[0021] 4) Stir the upper liquid phase with an aqueous ethanol solution with a mass concentration of 95%, centrifuge at 4000 r / min, and concentrate the phase liquid under reduced pressure to obtain jackfruit essential oil.

[0022] The pineapple essential oil that makes by said scheme has an oil yield of 0.198%.

Embodiment 2

[0024] A method for extracting essential oil from jackfruit peel as a raw material, the steps are:

[0025] 1) Add water twice its weight to the jackfruit peel from which the white skin layer has been removed, crush and squeeze, separate the liquid and filter to obtain a filtrate;

[0026] 2) Stir and mix 35% β-cyclodextrin, 20% sodium sulfate and the rest of water according to the mass concentration to prepare the extractant;

[0027] 3) When extracting, mix the filtrate and extractant at a ratio of 1:1, let it stand at 25°C for 35 minutes, and take the upper liquid phase;

[0028] 4) Stir the upper liquid phase with 90% ethanol aqueous solution, centrifuge at 3800r / min, and concentrate the phase liquid under reduced pressure to obtain jackfruit essential oil.

[0029] The pineapple essential oil that makes by said scheme has an oil yield of 0.194%.

Embodiment 3

[0031] A method for extracting essential oil from jackfruit peel as a raw material, the steps are:

[0032] 1) Add 1 times the weight of water to the jackfruit peel from which the white skin layer has been removed, crush and squeeze, separate the liquid and filter to obtain the filtrate;

[0033] 2) Stir and mix 45% β-cyclodextrin, 10% sodium sulfate and the rest of water according to the mass concentration to prepare the extractant;

[0034] 3) When extracting, mix the filtrate and extractant at a ratio of 2:1, let it stand at 35°C for 25 minutes, and take the upper liquid phase;

[0035] 4) Stir the upper liquid phase with an aqueous ethanol solution with a mass concentration of 92%, centrifuge at 4200 r / min, and concentrate the phase liquid under reduced pressure to obtain jackfruit essential oil.

[0036] The pineapple essential oil that makes by said scheme has an oil yield of 0.192%.

Abstract

The invention discloses a method for extracting essential oil by taking jackfruit peel as a raw material. The method comprises the following steps: (1) adding water in an amount which is 1-2 times the amount of jackfruit peel from which white cortex is removed into the jackfruit peel, crushing, squeezing, separating out liquid and filtering to prepare filtrate; (2) uniformly stirring 35-45 percent by mass of beta-cyclodextrin, 10-20 percent by mass of sodium sulfate and the balance of water to prepare an extractant; (3) mixing the filtrate with the extractant according to the ratio of (1-2):1 during extraction, standing for 25-35 min at the temperature of 25-35 DEG C and taking supernatant phase; and (4) stirring and centrifuging the supernatant phase and 90-95 percent ethanol aqueous solution, taking phase liquid and concentrating under reduced pressure to obtain the essential oil of the jackfruit peel. The extraction method is simple and easy to control, and has high thermal stability and high oil extraction rate; and the prepared jackfruit essential oil has the effects of eliminating phlegm, easing pain, diminishing swelling, fighting bacterium and diminishing inflammation.

Description

technical field [0001] The invention relates to an extraction method, in particular to a method for extracting essential oil from jackfruit peels. Background technique [0002] Jackfruit is a tropical evergreen tree of Moraceae. The fruit matures from June to July. The fruit is huge. It is called the king of fruits. It is rich in carbohydrates, sugar, protein, starch, vitamins, amino acids and various substances useful to the human body. minerals. At the same time, jackfruit also has high medicinal value and the effect of health and longevity. [0003] The nutritive value of the jackfruit peel is equivalent to the pulp and the fruit stone, but people tend to discard the peel after eating the pulp, which wastes resources and cannot reflect the utilization value and nutritional value of the jackfruit peel. After a certain period of time, the jackfruit skin will emit a bad smell, which will easily emulsify bacteria and attract flies, causing environmental sanitation problems....
