Description

Technical Field

[0001] The present invention relates to the technical field of deep processing of ginseng plants, and particularly to a method for removing pesticide residues from extracts of ginseng plants. Background Art

[0002] Scientific research has found that the main component of the extract of ginseng plants is "ginsenoside", whose main functions are to enhance heart function, promote metabolism, improve immune ability, delay aging, maintain a youthful appearance, etc., and it is mainly used as raw and auxiliary materials for medical and health care, beauty and body care products, etc. Due to the high use value, wide application range and broad development prospects of the extract of ginseng plants, it is necessary to remove pesticide residues before using ginseng plants. The existing removal methods have problems that impurities on the plant surface are likely to affect the removal effect during the process of removing pesticide residues and it is inconvenient to remove multiple plasticizers during the process of removing residues. Summary of the Invention

[0003] In order to solve the above technical problems, the present invention provides a method for removing pesticide residues from extracts of ginseng plants, which aims to clean the impurities on the plant surface during the removal process to prevent the impurities on the plant surface from affecting the removal effect and to perform multiple removal methods during the removal process to improve the removal effect.

[0004] A method for removing pesticide residues from extracts of ginseng plants specifically includes the following steps:

[0005] Step 1: Sort the plants. After digging out the plants to be removed, transport them to the processing workshop and perform sorting and stacking work.

[0006] Step 2: Rinse the plants. Use a booster pump to rinse and clean the neatly stacked plants.

[0007] In Step 2 of rinsing the plants, the first step: Fix the plants. Place and fix the stacked plants in a suitable position or on a fixing device to prevent the plants from rolling during the rinsing process and affecting the rinsing effect.

[0008] The second step: Select the equipment. According to the types of plants to be rinsed, select a suitable booster equipment and use clean water to rinse the plants.

[0009] The third step: Brush the plants. Use tools such as brushes to brush the surface of the plants during the rinsing process.

[0010] The fourth step: Rinse the plants. After brushing the plants, perform a secondary rinsing work on the surface of the plants.

[0011] Step 3: Clean the residues. After rinsing the plants, perform an immersion removal work on the plants.

[0012] In step three of cleaning residues, the first step: prepare acid water by mixing mature vinegar with water or soak the plants with their surfaces rinsed clean in mature vinegar for removal work;

[0013] The second step: prepare tea polyphenol solution by soaking tea leaves to obtain tea polyphenol solution, and move the plants soaked in acid water into the container of tea polyphenol solution for secondary soaking;

[0014] The third step: soak in warm water. After the previous two soakings, briefly dry the plants and then soak them in warm water;

[0015] The fourth step: rinse the surface. After soaking, use clean water rinsing tools to rinse and clean the plants;

[0016] Step four: dry the plants. Move the soaked and rinsed plants into the drying equipment for surface drying work, and then carry out the plant sun-drying work;

[0017] In step four of drying the plants, the first step: surface drying. Move the rinsed clean plants into the appropriate drying equipment to carry out drying and water-draining work on the plants;

[0018] The second step: plant sun-drying. After drying and draining the water from the plants, move the plants to a sunny place for sun-drying;

[0019] The third step: sampling and testing. During the sun-drying process, use sampling tools to sample the plants and carry out testing work on the samples;

[0020] Step five: plant packaging. Move the sun-dried plants to the packaging location, and use processing equipment and packaging equipment for processing and packaging after passing the testing.

[0021] Preferably, in the first step of step two, when fixing the plants, lay the plants flat for fixation to prevent interference between plants during the rinsing work.

[0022] Preferably, in the third step of step two, when brushing the plants, use a soft brush to prevent damage to the surfaces of the plants.

[0023] Preferably, in the first step of step three, when soaking the plants with acid water, control the soaking time between twenty minutes and forty minutes.

[0024] Preferably, in the second step of step three, when soaking with tea polyphenol solution, control the soaking time between ten minutes and thirty minutes.

[0025] Preferably, in the third step of step three, when soaking with warm water, control the temperature between thirty degrees and sixty degrees, and control the soaking time between ten minutes and twenty minutes.

[0026] Preferably, in the fourth step, in the first step, when drying the surface of the plant, the temperature is controlled between 35°C and 55°C and the drying time is controlled within one hour.

[0027] Preferably, in the fourth step, in the second step, when drying the plant in the sun, it is controlled within six hours in a sunny place.

[0028] Compared with the prior art, the present invention has the following beneficial effects: Since a method for removing pesticide residues from ginseng plant extracts of the present invention is widely applied to the deep processing field of ginseng plants. The present invention provides a reasonable removal process, which can remove more than 96% of the pesticide residues in the plants, so that the pesticide content and phthalate content in the plants are respectively lower than the pesticide residue limit indexes of 7.0% of CAC and 0.3% of the phthalate detection standard GB / T / T267. At the same time, during the removal process, through the brushing work on the surface of the plant in the second step, part of the pesticide residues and phthalates are removed during the process of removing the surface impurities of the plant. Then, through the third and fourth steps, the plants are soaked multiple times with different liquids, and the water evaporation is accelerated by drying, so as to carry away most of the phthalates and pesticide residues, and the removal work is carried out again during the drying process, so as to achieve the purpose of removing pesticide residues and phthalates from the plants.
