BHO Extraction

by Ajda | Jun 2, 2024 | Extractor

What is BHO Extraction?

BHO (Butane Hash Oil or Butane Honey Oil) is a concentrated cannabis extraction known for its high cannabinoids concentration, reaching up to 90%. The concentration depends on the strain of the cannabis flower.
This makes BHO extracts some of the most potent marijuana concentrates globally. BHO extracts are used to create various products, including topical treatments, vape juices, edibles, and more.

The BHO Extraction Process

BHO extraction involves using a high-purity butane gas to separate cannabinoids and terpenes from the raw cannabis plant material. During the BHO extraction process, butane gas passes through cannabis in a sealed cylinder, effectively extracting these valuable compounds. The raw extract’s golden color and viscous texture can be further processed to create different products like shatter, budder, and wax.

BHO extraction uses hydrocarbons as a solvent to extract resin from the cannabis plant. This resin, known as butane hash oil, or shatter, consists of purified cannabinoids and terpenes. Compared to other extraction methods, BHO extraction captures a comprehensive profile of cannabinoids, THC, terpenes, flavonoids, phenolic amides, and sterols, representing the original plant in a concentrated form.

Why Choose BHO Extraction?

Professional extraction companies prefer instrument-grade butane for its purity and low boiling point, enabling more complete cannabis extraction than solvents like carbon dioxide or ethanol. Properly conducted BHO extraction results in higher cannabinoid content, a broader terpene profile, lighter color, and better flavor compared to other methods.
Another important factor affecting the decision of the extraction process is the price. The price of BHO extraction is lower compared to other extraction methods, especially supercritical CO2 extraction.

When butane gas contacts the cannabis plant during BHO extraction, it extracts THC and terpenes from the plant matter. This process can produce different textures, ranging from oils and waxes to hard, brittle forms like shatter.

The Advantages of BHO Extraction

BHO extraction, when executed with professional equipment in a certified lab, offers numerous advantages:

Efficiency in cannabis extraction
Cost-effectiveness
Safety in commercial extraction
Great-tasting final products
Safety and enjoyment for consumers

Safety is an aspect that has to be considered. BHO extraction is very safe when all the safety regulations are applied. Besides having the equipment that is safe and tested,also the operator has to be educated on proper and safe use of the extractor.
You can find extractors on the market without any certificates and without safety measurements prepared for safe use.

These benefits explain why many consumers prefer BHO extracts and why businesses choose Exeat extractors for their BHO extraction needs. Exeat extractors can be custom-made to meet specific demands, with options from our regular offerings.

The Role of Closed-Loop System in BHO Extraction

Modern BHO extraction methods are incredibly safe, utilizing closed-loop systems that capture and recycle residual butane, preventing gas leaks and ensuring no butane is left behind. Commercial-grade closed-loop systems contain all flammable solvents, minimizing the risk of explosions and allowing for solvent recycling. This process is safer, more controlled, and more effective than open-loop extraction.

In closed-loop BHO extraction, butane is loaded into a pressurized tank, and the cannabis is placed in an extraction tube. Clean, odorless, and tasteless butane passes through the plant, extracting terpenes and cannabinoids.

Exeat produces closed loop extractors Extractors can be customised to fit individual needs or can be bought prebuild. They are produced according to relevant standards and approved by independent third party inspectors and institutions.

BHO Extracts: Use and Processing

BHO extracts are primarily used to create concentrated oil for vaporization cartridges or as dabbable concentrates sold by the gram. The oil can also be activated and incorporated into edibles, topicals, or distilled. Proper storage is crucial to maintain the potency and flavor of BHO concentrates, which can last for a year or more if kept in a cool, dry, and dark place.

Decarboxylation, Dewaxing, and Winterization

BHO concentrates require decarboxylation, the process of heating the substance to activate chemical acids into their parent cannabinoid compounds. Heating cannabinoid acids like THCA and CBDA converts them into the therapeutic THC and CBD compounds. Consuming raw BHO is not only dangerous, but also won’t contain any activated compounds. Without decarboxylation consumers will not feel the effect of the cannabis or hemp plant.

Dewaxing is the process of removing waxes and lipids from the final extract. Waxes and lipids can speed up the nucleation process and significantly affect the flavor and smoothness of the concentrate.

Winterization is one method of de-waxing. During winterization, BHO is dissolved into a polar solvent, usually ethanol, at sub-zero temperatures. The cold temperatures force lipids to the top for streamlined filtration.

Conclusion

BHO extracts and concentrates are popular due to their accessibility, portability, and versatility. They provide a user-friendly experience with various consumption options, making them suitable for different needs and preferences. BHO extraction, with its full spectrum extraction, addresses consumer demands better than other methods, offering a fast and efficient way to produce highly potent cannabis products.

While there are risks associated with BHO extraction, proper execution in a controlled environment ensures safety and quality. Partnering with a trusted provider like Exeat ensures you leverage the best in BHO extraction technology. Our machines have certificates to comply with the most stringent norms.
Instruction manual should be followed besides your state laws and the ATEX directive 2014/34/EU.

Terpenes in hemp flower

by Ajda | Mar 25, 2024 | Extractor, Impregnation machine

Introduction

We will explain what are terpens in hemp flower, what are the most known terpens, their qualities and usage.
We will also explain the correalation between terpens and cannabinoids. And for the end, we will tell you more about terpene preservation in vacuum infusion with cannabinoids.

What is hemp

Hemp (Cannabis Sativa L.) is a broadly grown plant worldwide. In the last years, the cannabidiol (CBD) and terpenes in hemp have had increasing research interest due to their human health benefits and pharmaceutical values.

There are two types of hemp plants:

the fiber type;
cannabinoids type hemp plant: rich in cannabinoids.

Depending on the level of tetrahydrocannabinol (THC) in the plant, the hemp can be further classified into industrial hemp (THC < 0.3%) and marijuana (THC > 0.3%).

What are terpenes

Terpens are organic, aromatic compounds found in plants in the form of oils. Essentially they are what gives a plant its unique flavour and aroma.

The most distinct characteristic of terpenes is the smell, which depicts the unique aromatic characteristics of hemp plant and is used by the plant to repel and defense against herbivores, attract pollinators, and inhibit the microbial growth.

There are currently more than 120 terpenes already identified in hemp. Terpenes are found in lots of fruits, vegetables and herbs and are recognized as safe for human consumption. Terpenes are used in a wide variety of foods and cosmetic products.

These fragrant oils are responsible for each strain’s unique smell and taste, but they also have a range of physiological and therapeutic effects. Such as anti-anxiety, pain-relief, relaxation promotion, anti-inflammation and antimicrobial activities.

The difference between cannabinoids and terpenes

What gives hemp its “character” are the hundreds of chemicals it contains. Among them are cannabinoids, terpenes and flavonoids.

While terpenes don’t get you high, they do influence the effects of other plant compounds such as THC and other cannabinoids.

Most common terpenes found in hemp

Most common therapeutic effects and benefits found in terpenes are:

antiviral,
antidepressant,
pain relieving,
anticancer,
antimicrobal.

Myrcene

One of the most common terpenes found in cannabis is myrcene. Myrcene is also found in hops and is responsible for the peppery, spicy, balsam fragrance in beer. It’s also expressed in lemongrass. Myrcene is a potent analgesic, and has great antioxidant and anti-inflammatory activities.

Caryophyllene

The terpene caryophyllene is present in many herbs and spices, including black pepper, basil, and oregano, and cannabis strains with high levels of it deliver a spicy, funky warmth to the nose, similar to cinnamon and cloves. Caryophyllene is an excellent analgesic agent and antispasmic in muscles.

Linalool

Linalool refers to two enantiomers of a naturally occurring terpene alcohol found in many flowers and spice plants such as lavender. Linalool is a colorless oil. Linalool shows sedative, anti-influenza, antimicrobial and neuroprotective effects.

Pinene

Pinene is an aromatic compound commonly found in cannabis that smells a lot like a forest of pine trees. But pinene can bring more to a strain’s experience than just flavor. Pinene has memory improvement, anti-inflammatory and anti-microbial functions.

Limonene

Limonene is a colorless liquid aliphatic hydrocarbon and is the major component in the oil of citrus fruit peels. Limonene shows good antiviral, anti-bacteria and antidiabetic properties.

Terpinolene

Terpinolene is found in lilacs, nutmeg, cumin, and apples.

Humulene

The subtle earthy, woody and spicy notes that give hoppy beers their distinct taste and aroma are also partly responsible for giving cannabis its unique scent. Hops and cannabis share a common terpene: humulene. It is very similar to Myrcene.

Eucalyptol

Eucalyptol has a fresh mint-like smell and a spicy, cooling taste. It is insoluble in water, but miscible with organic solvents. Eucalyptol makes up 90% of eucalyptus oil.

Terpineol

Terpineols are monocyclic, monoterpene tertiary alcohols that are naturally present in plant species. It has a pleasant odor, similar to lilacs, and is a common ingredient in perfumes, cosmetics, and aromatic scents.

Ocimene

Ocimene is the terpene responsible for some of the sweet and herbaceous flavors of certain cannabis strains, and it can also add citrusy and woody undertones. It may also offer a wide array of medicinal properties, as well as uplifting effects.

How can terpenes affect the effects of cannabis?

Terpenes can enhance or alter psychoactive and medicinal properties of hemp. This phenomenon is know as “entourage effect”.
It can be thought of as working as follows: the sum of all the compounds present in cannabis is greater than the sum of its parts. In other words, a special synergy of the whole plant occurs when cannabinoids and terpenes are consumed together, as opposed to when they are consumed separately.

Preserving terpens

Preserving terpens while using processing technologies to enrich the quality and compound of hemp is of great importance. Achieving high processing efficiency with minimal loss of bioactive compounds is necessary to ensure the quality and safety of hemp plants after harvest.

With vacuum impregnation machine API 3.0, it is possible to have an effect on cannabinoids composition and concentration, without altering the terpenes. That means that you can infuse hemp flower with our API 3.0 machine and preserve the terpenes. Without terpenes, cannabinoids would be far less effective, and far less flavorful.
