Embodiment 1

[0018] A preparation method of Zanthoxylum bungeanum oil dry powder, comprises the steps:

[0019] (1) Take 10 kg of pepper seeds with a moisture content of 15% to 20% and add them to the material tank of the electric air flow puffing machine. After heating until the temperature rises to 700°C and the pressure is 0.5Mpa, the material is extruded and discharged, and the material is added to the In the pulverizer, pulverize for 4 minutes and pass through a 20-mesh sieve to obtain the pepper seed powder;

[0020] (2) Put the Zanthoxylum bungeanum seed powder obtained in step (1) into a material bag, put it in an extraction tank, add 80kg of n-hexane of the Zanthoxylum bungeanum seed powder weight to extract for 8 minutes, after the extraction is completed, place the extraction tank at 5°C Perform rapid cooling, and after the temperature is constant, take out the material bag, place the n-hexane extract in a vacuum rotary evaporator, and treat it for 8 hours at a temperature of 72...

Embodiment 2

[0024] A preparation method of Zanthoxylum bungeanum oil dry powder, comprises the steps:

[0025] (1) Take 10 kg of pepper seeds with a moisture content of 15% to 20% and add them to the material barrel of the electric air flow puffing machine. After heating until the temperature rises to 735°C and the pressure is 0.6Mpa, the puffed seeds are extruded and the materials are added to the In the pulverizer, pulverize for 5 minutes and pass through a 30-mesh sieve to obtain the pepper seed powder;

[0026] (2) Put the Zanthoxylum bungeanum seed powder obtained in step (1) into a material bag, put it in an extraction tank, add 90kg of n-hexane of the Zanthoxylum bungeanum seed powder weight to extract for 9 minutes, after the extraction is completed, place the extraction tank at 8°C Perform rapid cooling, and after the temperature is constant, take out the material bag, place the n-hexane extract in a vacuum rotary evaporator, and treat it for 9 hours at a temperature of 72°C to 7...

Embodiment 3

[0030] A preparation method of Zanthoxylum bungeanum oil dry powder, comprises the steps:

[0031] (1) Take 10 kg of pepper seeds with a moisture content of 15% to 20% and add them to the material tank of the electrothermal airflow puffing machine. After heating until the temperature rises to 800°C and the pressure is 0.8Mpa, the puffed seeds are extruded and the materials are added to the In the pulverizer, pulverize for 6 minutes and pass through a 30-mesh sieve to obtain the pepper seed powder;

[0032] (2) Put the Zanthoxylum bungeanum seed powder obtained in step (1) into a material bag, put it in an extraction tank, add 100kg of n-hexane of the Zanthoxylum bungeanum seed powder weight to extract for 10 minutes, after the extraction is completed, place the extraction tank at 10°C Perform rapid cooling, and after the temperature is constant, take out the material bag, place the n-hexane extract in a vacuum rotary evaporator, and treat it for 10 hours at a temperature of 72...

Abstract

The invention discloses a preparation method of zanthoxylum bungeanum seed oil dry powder. The preparation method comprises the following steps of adding zanthoxylum bungeanum seeds into a bulking machine, bulking, and pulverizing to obtain zanthoxylum bungeanum seed powder; putting the zanthoxylum bungeanum seed powder into an extraction tank, adding n-hexane for extraction, cooling the extraction tank after the extraction is finished, taking out after the temperature is constant, putting the extraction liquid into a vacuum rotary evaporator, and removing the n-hexane to obtain zanthoxylum bungeanum seed oil; heating the zanthoxylum bungeanum seed oil to 40-50 DEG C, adding an oil-soluble antioxidant, stirring for dissolving, adding an oil-in-water emulsifier, stirring for dissolving, cooling to room temperature, adding a protein powder solution, putting into a high-speed disperser, treating for 3-5 minutes under the condition of 8000-10000rpm, and feeding into a vacuum freeze spray dryer for vacuum freeze spray drying and sublimation drying, and drying to obtain the zanthoxylum bungeanum seed oil powder. Compared with the method, the yield of the zanthoxylum bungeanum seed oil and the content of alpha-linolenic acid in the zanthoxylum bungeanum seed oil are increased, and meanwhile, the stability and the health-care effect of the zanthoxylum bungeanum seed oil are effectivelyguaranteed.

Description

technical field [0001] The invention belongs to the technical field of pepper seed products, and in particular relates to a preparation method of pepper seed oil dry powder. Background technique [0002] Zanthoxylum bungeanum is the main by-product in the production of Zanthoxylum bungeanum peel, with an annual output of more than 3 million tons, most of which are discarded as waste, resulting in a serious waste of resources. Saturated fatty acids are mostly saturated, of which the content of α-linolenic acid accounts for 30% of the total oil content of Zanthoxylum bungeanum. It is precisely because of the high content of unsaturated fatty acids that unsaturated fatty acids in Zanthoxylum bungeanum oil are easily decomposed and oxidized during processing and storage. Thereby causing the health care effect of prickly ash seed oil to have a discount greatly. [0003] The development of liquid Zanthoxylum bungeanum oil into powdered oil can improve the stability of Zanthoxylum...
