Products Description
Coffee oil extraction process extracting advantages:
1. High yield: The subcritical extraction technology can significantly increase the yield of coffee oil, with the yield usually above 20%.
2. Active ingredient protection: The low-temperature extraction process can effectively protect the active ingredients in coffee, avoiding the destruction of nutrients by high temperatures.
3. Solvent recovery: The solvent can be recycled and reused, reducing solvent loss and lowering costs.
4. No solvent residue: The product has no solvent residue, ensuring high safety and suitable for large-scale industrial production.
Coffee oil extraction Process Flow
Raw material preparation
Usually, dried coffee beans or coffee grounds are used as the raw materials. The drying process is generally carried out at a temperature of 40℃ to 60℃ for 2 to 10 hours.
Solvent selection
Common subcritical solvents include liquid propane, butane, isobutane or dimethyl ether.
Extraction conditions
Conduct combined extraction under the conditions of extraction temperature ranging from 20℃ to 60℃, extraction pressure ranging from 0.2MPa to 0.6MPa, and ultrasonic frequency ranging from 15KHz to 30KHz. The extraction time is 30 minutes to 60 minutes.
Post-treatment
After the extraction process is completed, the solvent is removed through low-temperature desolventization and thin-film evaporation, resulting in coffee oil.
Products Features
Advantages of subcritical fluid coffee oil extraction process:
1. Low-temperature extraction, preserving active ingredients
Principle: Supercritical fluids have high solubility at low temperatures and low pressures, enabling the extraction of active ingredients at lower temperatures.
Advantages: Low-temperature extraction can effectively protect heat-sensitive ingredients and prevent the destruction of nutrients by high temperatures.
2. Efficient extraction, increased yield
Principle: The solubility of subcritical fluids is relatively strong, enabling rapid dissolution of the target components, resulting in high extraction efficiency.
Advantages: Compared to traditional extraction methods, subcritical extraction technology can complete the extraction process in a shorter time, significantly increasing the yield of the extract.
3. No solvent residue, high safety
Principle: The solvents (such as carbon dioxide, butane, etc.) used in the extraction process by subcritical fluids can be completely removed after the extraction is completed, and will not remain in the extract.
Advantages: There is no solvent residue in the extract, which complies with food safety and pharmaceutical safety requirements, and is particularly suitable for the production of food, health supplements and pharmaceuticals.
