What Are CRC Extracts?

Color remediation column (CRC) technology is revolutionizing the cannabis industry by introducing a higher standard of purity, potency, and presentation in cannabis concentrates. 

This innovative filtration process removes unwanted flavors and colors from concentrates, as well as impurities, such as waxes, lipids, and chlorophyll, which can detract from the quality and experience of the product. 

CRC technology goes beyond enhancing the safety and aesthetic appeal of concentrates. It also preserves the essential terpenes and cannabinoids that define their therapeutic and sensory profiles. 

As the cannabis market continues to mature, CRC-treated cannabis extracts are becoming a benchmark for quality, offering consumers cleaner, more enjoyable products that reflect the true essence of the cannabis plant.

What Is CRC Technology?

At the heart of the latest cannabis extraction innovation lies CRC tech—a sophisticated filtration process designed to elevate the purity, flavor, and visual appeal of cannabis concentrates. 

By guiding extracted cannabinoids and terpenes through a carefully prepared column that can be filled with a variety of filtration media, CRC technology targets and removes unwanted compounds like waxes, lipids, and chlorophyll. These are the culprits behind the compromised quality of concentrates, affecting everything from taste to appearance.

CRC Filter Media

The effectiveness of CRC technology lies in its use of diverse filtration media, each selected for its specific adsorptive properties. The strategic combination of these diverse filter media within the CRC setup can be customized to meet specific extraction goals.

Here are some of the key CRC media, along with their primary functions:

  • Activated Charcoal: Known for its potent decolorizing abilities, it adsorbs organic compounds and pesticides, improving taste and clarity.
  • Silica Gel: Its high surface area effectively removes impurities, refining the concentrate's texture and consistency.
  • Bentonite Clay: Removes lipids and waxes, contributing to the smoothness and clarity of the final product.
  • Diatomaceous Earth: Traps fine particulates and ensures a high flow rate through the CRC, minimizing yield reduction.
  • Activated Alumina: Adsorbs contaminants without altering the chemical composition, preserving the integrity of cannabinoids and terpenes.
  • Activated Magnesium Silicate: Targets heavy metals and certain pesticides, enhancing the safety and purity of the concentrate.

CRC Process

The road from raw cannabis material to high-quality cannabis extract is both art and science. Here’s how cannabis plant matter undergoes the CRC extraction and filtration process.

  1. Extraction: The initial extraction of cannabinoids and terpenes from the cannabis plant material using solvents like butane, CO2, or ethanol produces a raw extract that contains a mixture of desired and undesired compounds.
  2. Filtration Through CRC: The extract is then introduced to the CRC, passing through layers of carefully selected filtration media. Each media type is chosen for its specific properties, allowing it to adsorb certain impurities without compromising the extract's quality.
  3. Final Product Collection: The refined extract, now free from impurities, is collected and prepared for further processing to achieve the desired product specifications.

Benefits of CRC Extracts

CRC technology has significantly impacted the cannabis concentrate industry by enhancing the product quality and safety. Here’s why both producers and consumers increasingly favor CRC extracts.

Improved Aesthetics

CRC-treated extracts often exhibit a more appealing color, ranging from bright yellow to clear. This visual enhancement results from removing pigments and other impurities, making the product more attractive to consumers.

Enhanced Flavor and Aroma

The selective filtration process preserves the terpenes responsible for the flavor and aroma of cannabis while removing undesirable tastes and smells. This results in a cleaner, more enjoyable sensory experience.

Elevated Purity

CRC technology's ability to strip away non-essential elements like waxes, lipids, and chlorophyll ensures a concentrate of higher purity. This purification process enhances the overall quality of the product and contributes to a smoother consumption experience, free from harshness often associated with impurities.

Common Myths and Concerns About CRC

Despite the clear benefits CRC technology brings to cannabis concentrates, several myths persist that can cloud consumer perception. Let's address a few:

Myth: CRC Removes All Beneficial Compounds

Contrary to this belief, CRC technology specifically targets and removes unwanted substances without stripping away the valuable cannabinoids and terpenes that contribute to the concentrate's effectiveness and sensory profile.

Myth: All CRC Extracts Taste Bad

The flavor of CRC-treated extracts depends significantly on the starting material and the extraction process. Properly processed CRC extracts can retain or even enhance the natural flavors and aromas of the cannabis plant.

Myth: CRC Is Used to Mask Inferior Extracts

Contrary to the myth, CRC technology is not about masking low-quality extracts but refining them. It removes impurities while preserving valuable compounds, enhancing the concentrate's overall quality, flavor, and aroma without serving as a disguise for inferior products.

Concern: Potential Respiratory Risks

Properly processed CRC-treated concentrates do not contain harmful levels of residual filtration media, posing little to no risk to consumer health. The industry's adherence to safety standards further minimizes any potential concerns.

How to Choose Quality CRC Extracts

When selecting high-quality CRC extracts, it's essential to look beyond superficial qualities and understand the nuances of what makes a good concentrate. Here are some tips to guide you:

  • Transparency from Producers: Look for producers who are open about their CRC process, including the materials used in filtration. Transparency is critical to trust and quality assurance.
  • Lab Testing and Certificates of Analysis (COAs): Reputable producers will provide lab testing results, including potency and contaminant tests. COAs ensure that the extract meets safety standards and retains its potency and terpene profile after the CRC process.
  • Appearance and Consistency: While CRC extracts are known for their clarity and purity, good quality concentrates should also have a consistent texture and appearance that reflect careful processing.
  • Flavor and Aroma: High-quality CRC extracts should retain the cannabis plant's natural flavors and aromas. A pleasant and authentic taste is a good indicator of a well-executed CRC process that preserves terpenes.

A New Chapter in Concentrate Quality

It's clear that CRC technology is a game-changer for cannabis concentrates. It focuses on purity and quality without overshadowing the plant's natural essence. As the industry evolves, CRC extracts represent innovation, offering consumers a cleaner, more enjoyable experience. 

It's an exciting time for cannabis enthusiasts and a step forward in ensuring that concentrates not only look and taste better but are also safe and consistent. Looking ahead, the future of cannabis concentrates is bright, with CRC leading the way in quality and innovation.
