What Are the Different Botanical Extraction Techniques?

Consumers and manufacturers love to use and sell products with natural ingredients. Manufacturers can claim that their product is safe and healthy because it has no artificial additives.

On the other hand, consumers enjoy the healthy feeling they get from using these products. But have you ever thought about where these natural ingredients come from?

These natural botanical extracts are plants or parts of plants that scientists remove for other uses. They draw these extracts through several botanical extraction methods.

Using these botanical extraction techniques makes several botanical ingredients available for manufactured products. So, we’ll explore some of the best botanical extraction methods in the guide below!

Freeze-Thaw-Assisted Botanical Extraction

One common botanical extraction method is freeze-thaw-assisted extraction. This is a sustainable botanical herbal extract approach for decomposing plant tissue and cell membranes.

This pretreatment increases the amount of cell membrane permeabilization. This approach makes it easier for chemists to extract items from the plant. Several industries use this technology to enhance their extraction yields.

Pressurized Hot Water Extraction

Pressurized hot water extraction (PHWE) is one of the cleanest and green methods for extracting materials. This approach improves traditional water extraction, which is often inefficient. It also reduces your selectivity.

So, how does this treatment make the process more efficient? PHWE uses water-heated above its atmospheric boiling point. Usually, this technique heats water to 100 degrees Celsius.

But, this doesn’t mean that you can heat the water to any temperature. Your water mustn’t exceed the supercritical limit. The minimum temperature for this is 374 degrees Celsius.

Often, scientists use this technique to access polar extracts. Some companies use them to produce botanical extracts skincare products.

Ultrasonic and Microwave Intensification Techniques

Some scientists use ultrasound and microwave botanical extraction equipment to get greater extract access. These methods make it easier for scientists to extract materials from plant life.

So, how does this work? First, microwave-assisted extraction uses radiation to heat the solvent mixture. This makes the solvent more accessible and speeds up the partitioning process.

Ultrasound extraction uses 20kHz frequency pulses to generate local hotspots at a high scale. This approach produces cavitational bubbles that burst at the plant’s matrix.

This burst breaks down the cell walls and allows several active compounds to enter a solution. These methods often use less solvent and take less time, making them more efficient.

Supercritical Fluid Extraction (SFE)

SFE is the final technique that researchers use. Many believe that this is a promising method of green extraction.

SFE uses fluids with properties between liquid and gas as extraction solvents. This method is safe, green, and affordable for researchers.

As it stands, most companies use this technique for decaffeination. But, many researchers are looking for new ways to use this method.
