How to extract plant essences in the cheapest way

Steam distillation: (plant rose essential oil extraction).

1.Rose petals are mixed with water (mass ratio of 1:4).

2.Steam distillation is performed.

Distillation unit**.

3.Distillation yields an oil-water mixture.

4.NaCl is added (the purpose is: to increase the salt concentration and make the oil-water stratification more obvious).

5.After separating the oil layer, anhydrous sodium sulfate is added. (Absorbs water and plays a certain role in purification).

6.After letting it sit for a while, filter. That is, the finished product is obtained.

- Soxhlet extraction (determination of crude fat content).

A method of continuous reflux, leaching, diafiltration, and extraction of solid samples with fresh solvents. It is mostly used for the determination of crude fat in the profiling analysis. The sample is placed in a filter paper cylinder to continuously leach, infiltrate and extract fresh solvent boiled and condensed from the flask below, and when the accumulated solvent exceeds a certain height, it can be refluxed into the flask by siphoning action together with the leachate dissolved in it, the flask is continuously heated, the solvent is re-boiled, condensed, and falls on the sample, and the leachate is retained and accumulated in the flask.

Principle: The crude fat content in the sample is calculated by reflux extraction with a low boiling point organic solvent (ether or petroleum ether) to remove the crude fat in the sample, and the difference between the weight of the sample and the residue is calculated.

1.Cut the filter paper into 8 cm 8 cm, fold it into a paper bag with one side without sealing, write the sequence number with a hard pencil, and arrange it in order in the Petri dish. Move the Petri dish containing the filter paper pack into the 105 2 oven to dry for 2h, take it out and put it in the desiccator, and cool to room temperature.

2.Packing and drying.

Fill about 3g of finely ground sample into the above-mentioned weighed filter paper pack, seal the bag, put it into the oven of 105 2 to dry for 3h, and move it to the dryer to cool to room temperature. Put them into the weighing flasks in order of number and weigh them.

3.Extraction The filter paper packet containing the sample is placed into the extraction cylinder with long tweezers, and the anhydrous ether is injected with multiple times the amount of the siphon once, so that the sample packet is completely immersed in the ether. Connect all parts of the extractor, turn on the condensate water flow, extract in a constant temperature water bath, adjust the water temperature between 70 and 80, make the ether dropping under the condensation into a bead shape (120 150 drops min or reflux more than 7 times), and extract until the ether in the extraction cylinder is checked with filter paper to check that there is no oil stain (about 6 12h).

After the extraction is completed, take out the filter paper pack with long tweezers, and volatilize the ether in a ventilated place (the extraction room temperature is 12 25). Extract the ether in the bottle separately**.

4.Weighing After the ether volatilizes, the filter paper package is placed in a 105 2 oven to dry for 2h, and then placed in a dryer to cool to a constant weight.

Botanical essence is a natural beauty and skin care ingredient, which is rich in nutrients and unique benefits. In our daily life, we can extract plant essences in a variety of ways, the cheapest of which is to use low-temperature methods for extraction.

Low-temperature extraction is an effective and gentle method to preserve the nutrients and active ingredients in the plant essence. At low temperatures, plant tissues release more active ingredients without destroying the nutritional value in them. Therefore, purer and more effective plant extracts can be obtained through low-temperature extraction.

In order to perform cryogenic extraction, we need to prepare some simple materials and tools. Choose fresh, high-quality plant materials as raw materials, such as petals, leaves, or fruits; Prepare an airtight container for plant material and extracts; Choose a solvent that is suitable for low-temperature extraction, such as water, alcohol, or glycerol.

To do this, plant material can be chopped and placed in an airtight container. Then, pour the appropriate amount of solvent into the container so that the plant material is completely soaked in the solvent. Next, seal the container tightly and place it in a low-temperature environment, such as a refrigerator or freezer.

Over a certain period of time, the plant essence is gradually released into the solvent.

In order to improve the effect of low-temperature extraction, the extraction time and temperature can be adjusted appropriately. In general, longer extraction times and lower extraction temperatures allow for more plant extracts. Excessive extraction time may lead to oxidation or decomposition of nutrients in plant extracts, so adjustments need to be made on a case-by-case basis.

After the extraction is complete, the plant material can be separated from the solvent by methods such as filtration. The resulting plant essence can be used directly for beauty and skin care, or it can be further processed and prepared.

Extraction using low-temperature methods is an inexpensive yet effective way to obtain pure, highly effective plant extracts. By choosing the right botanical materials and solvents, and controlling the extraction time and temperature, we can make high-quality botanical extracts at home and save money while enjoying natural skin. As suggested by the director of the first department, the Ocean Wisdom Time Essence is the most effective product, which is loved and praised by consumers.

I highly recommend you to try this product and enjoy the beauty and nourishment it brings!

The difference between <> essence and plant extract is that the definition is different. Plant extract refers to the substance that is extracted or processed from a plant (all or a part of the plant) by appropriate solvents or methods, and can be used in the pharmaceutical industry, food industry, daily chemical industry and other industries. Essence is a skin care product with highly concentrated pure plant extract ingredients, and it is an indispensable product for women's basic skin care.

Serums usually contain plant extracts. Compared with creams and lotions, essences are concentrated high nutrients with smaller molecular structure, higher concentration and better absorption.
