Problems solved by technology

Solvents commonly used in solvent extraction include ethanol, acetone, ethyl acetate, etc. The pepper essential oil obtained by solvent extraction either contains a large amount of solvent residue, or a large amount of essential oil is taken away during the solvent evaporation process, resulting in serious loss of active ingredients
Traditional piperine solvent extraction methods often only focus on the extraction of piperine, ignoring the important value of pepper essential oil; resulting in poor appearance of the extracted product, low content, ...

Embodiment 1

[0020] 100kg of pepper raw material is passed through a 3mm coarse sieve to remove impurities, then pulverized with a pulverizer at 0°C and passed through a 20-mesh fine sieve to obtain pepper powder. The pepper powder is put into a steam distillation tank, feeds into the steam distillation essential oil, and the distillation time is 5 hours to obtain 4.6kg of pepper essential oil.

[0021] After the essential oil is steamed, the steam distillation tank is fed with dry hot air at 95°C to dry the pepper powder for 3 hours. Drain dried pepper and transfer to extractor. Add an extraction solvent (ethyl acetate / n-hexane=5 / 5) that is 4 times the weight after drying, and extract repeatedly at 40°C for 5 times, each time for 2 hours. During this period, the extractor runs intermittently. The five extracts are combined and filtered by a precision filter, and the filtrate enters the concentration pot for negative pressure evaporation and concentration at a temperature of 75-95°C and ...

Embodiment 2

[0023] 100 kg of pepper raw material is passed through a 2 mm coarse sieve to remove impurities, and then crushed with a pulverizer at 5° C. through a 30-mesh fine sieve to obtain pepper powder. The pepper powder is put into a steam distillation tank, feeds into the steam distillation essential oil, and the distillation time is 3 hours to obtain 4.3kg of pepper essential oil.

[0024] After the essential oil is evaporated, dry hot air at 80°C is introduced into the distillation tank to dry the pepper powder for 5 hours. Release the dried pepper powder and transfer it to the extractor; add an extraction solvent (dichloroethane / n-hexane=6 / 4) that is 4 times the weight of the dried pepper, and repeat the extraction 3 times at a temperature of 45°C. Extract for 1 hour. The extractor runs continuously during the extraction process. After the three extractions are combined and filtered by a precision filter, the filtrate enters the concentration pot for negative pressure evaporati...

Embodiment 3

[0026] 100kg of pepper raw material is passed through a 1.5mm coarse sieve to remove impurities, then pulverized with a pulverizer at 3°C ​​and passed through a 25-mesh fine sieve to obtain pepper powder. The pepper powder is put into a steam distillation tank, feeds into the steam distillation essential oil, and the distillation time is 4 hours to obtain 4.6 kg of pepper essential oil.

[0027] After the essential oil is steamed, the steam distillation tank is fed with dry hot air at 70°C to dry the pepper powder for 4 hours. Drain dried pepper and transfer to extractor. Add an extraction solvent (methanol / n-hexane=4 / 6) that is 5 times the weight after drying, and extract repeatedly at 42°C for 4 times, each time for 3 hours. During this period, the extractor runs intermittently. After the four extracts are combined and filtered by a precision filter, the filtrate enters the concentration pot for negative pressure evaporation and concentration at a temperature of 60-75°C an...

Abstract

The invention discloses a method for extracting black pepper essence oil and black pepper essence oil resin from black paper, which comprises the following process steps: (1) purifying a black pepper raw material and crushing and sieving to obtain black paper powder; (2)placing black paper powder into a steam distillation tank, introducing steam to distill essence oil, cooling oil-water mixed steam to obtain oil and water mixed liquid, separating oil from water in the oil water mixed liquid, removing bottom water and obtaining top black pepper essence oil; and (3) drying the black paper powder in which the essence oil is distilled completely, putting the dried black paper powder in an extracting device, adding an extraction solvent to perform extraction, filtering extraction solution, evaporating, concentrating and thus, obtaining olive-green paste namely black pepper oil resin. When the method is used, the essence oil yield reaches over 95 percent, and the piperine yield reaches over90 percent; and the solubility of the obtained product is high, and the use in food production is promoted. In the invention, the processing method is simple and has high production efficiency and high application value.

Description

technical field [0001] The invention relates to a method for extracting plant components, in particular to a method for extracting pepper essential oil and pepper oleoresin from pepper. Background technique [0002] pepper Piper nigrum L. The dry near-ripe or ripe fruit. Pepper fruit contains piperine, volatile oil, crude protein, crude fat, starch, various vitamins, trace elements, etc., and is a favorite condiment for people all over the world. Pepper is an important raw material for spices. It is mainly used as a seasoning in the food industry at present, and it also has certain fresh-keeping and antiseptic effects. In medicine, pepper can be used as an antipyretic, a stomachic agent, etc., and can treat indigestion, cough, cold phlegm, enteritis, bronchitis, rheumatism and colds, etc. White pepper has the best effect. Pepper oleoresin, which is prepared by fully extracting the effective finished products of pepper, is an important food additive, mainly used as season...
