Problems solved by technology

This method also has defects. First, the problem of solvent residue leads to impure flavor of the product
The second is that the volatilization of the solvent during the heating process increases the product cost virtually, and causes a certain degree of pollution to the atmospheric environment
However, relying solely on the supercritical CO2 extraction method for extraction, the extraction rate of the numbness components in the pepper is low, only 40-50%, and it takes a long time and requires a lot of manpower and material resources.
In order to shorten the extraction time, increase the yield, and reduce the consumption of manpower and material resources, ethanol is usually used as an entrainer in the process of supercritical CO2 extraction of Zanthoxylum bungeanum pepper, and after extraction, it is necessary to carry out desolvation residue treatment, which not only increases the workload, but also in The process of desolvation residue treatment will cause the loss of prickly ash aroma and numbing substances

Abstract

The invention relates to an extraction method of effective ingredients of peppers, in particular relating to an efficient extraction and separation technology for effective ingredients of peppers, comprising the following steps: (1) pulverization: pulverizing pepper raw materials at the temperature of 0-5 DEG C; (2) extraction and separation of the aroma ingredient of the peppers: adding pepper powder into an extraction kettle, and carrying out variable frequency ultrasonic extraction; causing mixed gas to successively enter an analytical kettle 1 and an analytical kettle 2 to collect the aroma ingredient of the peppers; and (3) extraction and separation of the spicy ingredient of the peppers: lowering the pressure of the extraction kettle to be less than or equal to 7.3MPa, then slowly raising the extraction pressure to 25-30MPa, maintaining ultrasonic frequency of 10-50khz, power of 1200w, the pressure of the analytical kettle 1 of 6-8MPa, and the pressure of the analytical kettle 2 of 4-6MPa; and collecting the numb-taste components of the peppers. The extraction method has the advantages that the process is simple, no organic solvent is adopted, and a pure physics method is adopted for extraction, and the obtained product is high in yield and high in unit content.

Description

technical field [0001] The invention relates to an extraction method of active ingredients of peppercorns, in particular to an extraction and separation process of effective ingredients of peppercorns using ultrasonic enhanced supercritical extraction, and belongs to the field of extraction and refining of natural spices. Background technique [0002] The vast majority of Zanthoxylum bungeanum is sold and consumed in the form of whole dried Zanthoxylum bungeanum peels. During storage and sales, Zanthoxylum bungeanum is prone to moisture absorption, mildew, and its aroma is easily lost. The aroma and numbness of the main components gradually weaken with time, making it difficult to preserve. [0003] Processing Zanthoxylum bungeanum into Zanthoxylum bungeanum oil can be conveniently preserved. At present, the production methods of Zanthoxylum bungeanum oil mainly include oil-soluble method, oil immersion method, oil drenching method, organic solvent extraction method, pressing...
