Harvesting and Freezing Fresh Cannabis
The foundation of high-quality live resin lies in the immediate preservation of fresh cannabis plants after harvest. To maintain the terpene profile and cannabinoid integrity, the plant material must be frozen promptly, minimizing degradation caused by heat, oxygen, and light exposure.
Once the cannabis plants reach optimal maturity, they should be harvested carefully to avoid bruising or damaging the trichomes, which contain the essential oils and cannabinoids. After cutting, the fresh plant material is trimmed to remove large fan leaves, which contain fewer cannabinoids and terpenes, focusing on preserving the sugar leaves and buds.
The freshly trimmed cannabis is then flash-frozen using either dry ice or a blast freezer, which rapidly lowers the temperature to -20°C (-4°F) or below. This rapid freezing halts enzymatic activity and preserves the volatile terpene compounds that are often lost during traditional drying and curing processes. Keeping the plant frozen until extraction is critical to producing true live resin.
Extraction Process for Live Resin
Live resin extraction involves using solvents to separate cannabinoids and terpenes from the frozen plant material while maintaining the delicate terpene profile. Butane and propane are the most commonly used hydrocarbons in live resin extraction due to their low boiling points and ability to preserve aromatic compounds.
The frozen cannabis is loaded into an extraction column, and the solvent is passed through the material under controlled temperature and pressure. This process dissolves cannabinoids and terpenes without extracting unwanted chlorophyll or plant waxes. The solvent mixture containing cannabinoids and terpenes is then collected and purged of residual solvents through vacuum ovens or closed-loop systems.
Key factors during extraction include:
- Maintaining low temperatures to preserve terpene profiles
- Using closed-loop extraction systems for safety and purity
- Employing vacuum purging to remove residual solvents without degrading cannabinoids
Post-Extraction Purging and Refining
After initial extraction, the crude live resin contains residual solvents and impurities that must be removed to ensure safety and product quality. Vacuum purging is the preferred method, where the extract is placed in a vacuum oven at low heat to evaporate solvents gently.
The purging parameters are carefully controlled:
- Temperature typically ranges from 30°C to 45°C (86°F to 113°F)
- Vacuum pressure is adjusted to expedite solvent removal without boiling off terpenes
- Duration varies depending on batch size and solvent concentration, often several hours to days
Some producers further refine live resin by winterization, where the extract is dissolved in ethanol and cooled to precipitate fats and waxes, which are then filtered out. This step improves the clarity and flavor of the live resin but may also reduce some terpene content if not carefully managed.
Comparison of Extraction Solvents
Choosing the right solvent is essential to achieving the desired live resin quality and safety profile. The table below compares common solvents used in live resin extraction:
| Solvent | Boiling Point | Terpene Preservation | Safety Considerations | Common Use |
|---|---|---|---|---|
| Butane (C4H10) | -0.5°C (31°F) | High | Highly flammable; requires closed-loop systems | Standard live resin extraction |
| Propane (C3H8) | -42°C (-44°F) | Very high (better terpene retention than butane) | Extremely flammable; specialized equipment needed | Used in blends for enhanced flavor |
| CO2 | 31°C (supercritical) | Moderate | Safe and non-flammable; expensive equipment | Alternative extraction; less common for live resin |
| Ethanol | 78°C (172°F) | Lower (terpene loss likely due to heat) | Flammable; food-grade ethanol preferred | Winterization and refinement, not primary live resin solvent |
Understanding the Live Resin Extraction Process
Live resin is a type of cannabis concentrate known for its preservation of terpenes and cannabinoids, resulting in enhanced flavor and potency. The key to producing high-quality live resin lies in the extraction process, which begins with fresh, flash-frozen cannabis rather than dried and cured flower.
The process can be broken down into several critical stages:
- Harvesting and Freezing: Cannabis plants are harvested at peak maturity and immediately flash-frozen to preserve the terpene profile and cannabinoid content.
- Preparation of Biomass: The frozen plant material is kept at low temperatures to prevent degradation and is prepared for solvent-based extraction.
- Extraction: A hydrocarbon solvent, typically butane or propane, is passed through the frozen biomass to dissolve cannabinoids and terpenes.
- Purging: The solvent is carefully removed via vacuum purging to yield a viscous, terpene-rich concentrate.
- Post-Processing: Final adjustments may include whipping or crystallization techniques depending on the desired consistency and product type.
