Method for extracting pepper essential oil and pepper oleoresin from pepper

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...

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, serious loss of essential oil, which does not meet the application requirements of the food industry

For example, the patent application number is 00130396.1 discloses a "preparation method of pepper oleoresin", which uses two or more mixed solvents to extract pepper oleoresin, which will cause more than 50% loss of essential oil in the solvent recovery process , and the obtained pepper oleoresin is relatively viscous and has poor solubility; the pepper essential oil is not effectively retained, and the flavor of the obtained product is greatly reduced
