Problems solved by technology

[0004] Because the essential oil content in plants is very small, and the obtained essential oil components are complex, it is difficult to purify
Solvent extraction of essential oils is a commonly used extraction method. Although the equipment is simple, cheap, and high in yield, it requires a large amount of organic solvents and contains many impurities; supercritical CO 2 Although the fluid extraction method has the advantages of high efficiency, low temperature, high yield, greenness, and no solvent residue, it has large equipment investment, high technical requirements, and great limitations.

Embodiment 1

[0024] Crush white pepper through a 120-mesh sieve, weigh 50.00 g and place it in a 2000 mL three-neck flask, soak it in 150 mL distilled water for 6 hours, add 100 mL of diethyl ether, 8 times the amount of solvent, add distilled water, and inject steam into the steam generator for 12 hours. Control the extraction temperature below 100°C. The extracted product was fully cooled, extracted with 10 mL of ether each time until the liquid was colorless, dried with anhydrous sodium sulfate, and collected by rotary evaporation to obtain a yellowish transparent liquid, namely white pepper volatile oil, with an extraction rate of 2.6535%.

Embodiment 2

[0026] Crush white pepper through a 120-mesh sieve, weigh 50.00 g and place it in a 2000 mL three-neck flask, soak it in 150 mL distilled water for 8 hours, add 100 mL of ether, add distilled water to 9 times the amount of solvent, and inject steam into the steam generator for 14 hours , control the extraction temperature below 100°C. The extracted product was fully cooled, extracted with 10 mL of ether each time until the liquid was colorless, dried with anhydrous sodium sulfate, and collected by rotary evaporation to obtain a light yellow transparent liquid, namely white pepper volatile oil, with an extraction rate of 2.6615%.

Embodiment 3

[0028] Crush white pepper through a 140-mesh sieve, weigh 50.00 g and place it in a 2000 mL three-necked flask, soak in 150 mL of distilled water for 4 hours, add 100 mL of diethyl ether, add distilled water to 8 times the amount of solvent, and extract with steam for 14 hours , control the extraction temperature below 100°C. The extracted product was fully cooled, extracted with 10 mL of ether each time until the liquid was colorless, dried with anhydrous sodium sulfate, and collected by rotary evaporation to obtain a yellowish transparent liquid, namely white pepper volatile oil, with an extraction rate of 2.7510%.

Abstract

The invention relates to a method for extracting white pepper volatile oil. The method comprises the steps of picking new white pepper, steeping for decrustation, airing, cold-storing, smashing the dried white pepper, extracting with a steam distillation-diethyl ether extraction combination method for a plurality of hours, salting out, drying with a drying agent, and recovering a solvent under reduced pressure to obtain the white pepper volatile oil. According to the method, the operation is simpler, the extraction time is shorter, meanwhile, the problem of a traditional steam distillation method that the extraction rate is affected due the fact that part of the volatile oil is adsorbed on the wall of an extractor is avoided, and the method is widely applied to extraction of white pepper and other volatile components at present, and is a new technology for extracting the white pepper volatile oil.

Description

technical field [0001] The invention relates to a method for extracting white pepper volatile oil. Background technique [0002] Volatile oil is also called essential oil, essential oil or aromatic oil. The composition of essential oil is mainly composed of terpenoids (mainly monoterpenes and sesquiterpenes), as well as non-terpenoid aromatics and aliphatics. Volatile oil (essential oil), as one of the effective components of pepper, has a variety of biological activities and physiological effects, and has shown gratifying effects on the cardiovascular and cerebrovascular systems, nervous system, and digestive system. Because it has a good inhibitory effect on a variety of bacteria and fungi, it can accelerate blood circulation in local tissues and promote epithelial cell regeneration, so it can play a role in detoxification, weight loss, beauty and moisturizing; in addition, it can be used in food processing industry, As a food preservative and flavoring agent, it can impr...
