Embodiment 1

[0030] As shown in Fig. 1, a kind of ultrasonic-assisted method for extracting pepper oleoresin comprises following extraction steps:

[0031] Step 1. Clean 100 kilograms of selected white pepper dried fruits, dry or dry them, crush them, and pass through a 40-mesh sieve to make pepper powder;

[0032] Step 2, put the pepper powder obtained in step 1 into 800 kilograms of 95% ethanol and soak for half an hour, and the soaking temperature is 40° C. to obtain a soaking solution;

[0033] Step 3. Put the soaking solution obtained in step 2 into an ultrasonic device for ultrasonic enhanced extraction, wherein the ultrasonic extraction frequency is 40KHz, and the ultrasonic intensity is 20W / cm 2 , the extraction temperature was 48° C., and the extraction time was 50 minutes to obtain extract I;

[0034] Step 4, the extract I obtained in step 3 is subjected to solid-liquid separation by vacuum filtration to obtain a liquid phase and a solid phase, and the obtained liquid phase is t...

Embodiment 2

[0038] A method for ultrasonically assisted extraction of pepper oleoresin, comprising the following extraction steps:

[0039] Step 1. Clean 120 kilograms of selected white pepper dried fruits, dry or dry them, crush them, and pass through a 60-mesh sieve to make pepper powder;

[0040] Step 2, put the pepper powder obtained in step 1 into 1000 kilograms of acetone solution and soak for 40 minutes, and the soaking temperature is 50° C. to obtain the soaking solution;

Abstract

The invention provides a method for ultrasonic-assisted extraction of pepper oil resin which comprises the following procedures: peppers are cleaned, sundried or oven-dried, and pulverized into pepper powder; the pepper powder is put into the extraction solvent for dipping treatment to obtain the dipping solution; the dipping solution is put into ultrasonic equipment for ultrasonic enhanced extraction to obtain an extract I; the extract I is made a solid-liquid separation to obtain a liquid phase and a solid phase, and the liquid phase is the extract liquid I; the solid phase is put into the ultrasonic equipment for second ultrasonic enhanced extraction to obtain an extract II, then the extract II is made the solid-liquid separation, the obtained liquid phase is the extract liquid II; the extract liquid I and the extract liquid II are merged, then are made a pressure-reducing distillation, the extraction solvent is separated, and the brown pasty fluid, namely pepper oil resin, can be obtained. The method has simple operation, strong practicability, short time used to extract the pepper oil resin, convenience and quickness, high extraction yield, short production cycle and low cost.

Description

technical field [0001] The invention relates to a method for extracting pepper oleoresin, in particular to a method for ultrasonically assisted extraction of pepper oleoresin. Background technique [0002] Pepper is an evergreen small tree plant, which is divided into white pepper and black pepper. It has a specific aroma and a strong spicy taste; the main components of pepper are piperine, piperine and other amides. It is the volatile oil of components such as piperonal and dihydrocarveol, that is, essential oil. [0003] In the food industry, according to the No. 4 Document of the Ministry of Health of the People's Republic of China in 2003, pepper oleoresin and pepper oil were approved as new varieties of food additives; pepper oleoresin is a natural extract of white pepper or black pepper, which is low in cost and easy to store , transportation, European and American countries have a long history of use. [0004] Traditionally, pepper oleoresin is prepared by simple im...
