The Rad Extracts Sub Zero Extraction Process

Looking for the best quality, most effective CBD extract products? RAD Extracts is here to help!

Our CBD extracts are exactly what your business needs to offer consumers CBD products that maximize benefits and encourage customers to keep coming back to your brand for their CBD needs. As an organic extract manufacturer, one of the secrets to our success lies in our extraction process: sub-zero extraction.

What Is Sub Zero Extraction and Why Is It So Great?

Sub Zero Extraction involves freezing the plant to around -20 degrees for about 24 hours. The extraction process consists of first, soaking the frozen hemp with frozen Food-Grade, USDA organic sugar cane alcohol, next using a centrifuge, the alcohol tincture mixture is separated from the plant. The alcohol tincture mixture now has CBD, other cannabinoids, terpenes, and flavonoids in the alcohol and is filtered to remove any plant particulates. The last step is pumping the alcohol tincture mix through a falling film, heated column, which evaporates off the alcohol and leaves behind the high-quality, ready-to-use full-spectrum extract.

An advantage of this extraction method is that a high-quality hemp plant can become a full spectrum extract without further extractions, which means it likely benefits the most from the entourage effect.

Why? Because the plant components are working together synergistically increasing the beneficial properties provided by the extract [2]. These high-quality full spectrum extracts that are processed in our organic extract manufacturing facility are a promising choice for therapeutic benefits [3].

That’s the gist of the process, but the most compelling part is the amazing benefits of Sub Zero Extraction:

  • Get a concentration of 61-70% CBD
  • Produces a higher quality full-spectrum oil- More minor cannabinoids such as CBG, CBC, and other minor cannabinoids, also has more terpenes, flavonoids and other beneficial Phyto-chemicals present to create the entourage effect.
  • CBD extract with no plant lipids or chlorophyll present
  • The natural terpene profile is preserved

Essentially, Sub Zero Extraction provides a higher quality full spectrum CBD when coupled with high quality input hemp material. This effective, high-quality extract can be leveraged for a variety of different products.

Whether it’s tinctures, edibles, or topicals, the effective, full spectrum, and entourage effect quality of this type of extraction make it ideal for a diverse array of CBD extract products.
