Celery seed essential oil has a good inhibitory effect on gram-positive bacteria such as Staphylococcus epidermidis, Staphylococcus aureus and Bacillus subtilis, and its MIC and MBC values are all 5% or less; and for E. coli and Pseudomonas aeruginosa The inhibitory effect of Gram-negative bacteria such as Proteus and Proteus is poor, with MIC and MBC values of 5% or more.
Anti-oxidation
Celery seed essential oil has strong anti-oxidant ability in scavenging free radicals, and as the concentration increases, the ability in scavenging free radicals and anti-oxidation also increases. And compared with the ability of BHA and BHT in scavenging free radicals and antioxidants, celery seed essential oil is stronger than these two traditional synthetic antioxidants in scavenging free radicals or antioxidants.
In summary, celery seed essential oil has shown good ability in antibacterial and sterilization, as well as in scavenging free radicals and anti-oxidation. In addition, it comes from plants, has low volatility and low toxicity. It has broad application prospects in food, medicine, chemical and other fields.
Prevention and treatment of cerebral ischemia
Celery seed contains 50 times the blood pressure and lipid-lowering components of celery. Celery and celery seed oil have preventive and therapeutic effects on brain aging and cerebral ischemia.
Studies have shown that celery seeds are rich in oil and contain a variety of pharmacologically active ingredients, which have the effects of dispelling qi, reducing swelling, diuresis, anti-tumor and anti-aging. It is reported in the literature that Apigenin A and Apigenin B can prolong the sleep time of mouse pentobarbital sodium and have a wide range of anticonvulsant effects. At the same time, it has a certain protective effect on brain cells.
Experiments show that celery seed oil can significantly improve the brain index and brain edema of rats with cerebral ischemia. At the same time, celery seed oil can improve the neurobehavioral symptoms of MCAO rats and reduce the area of cerebral infarction. It shows that celery seed oil can improve the ischemic state of the brain tissue, reduce the ischemic damage of the brain tissue, and achieve the effect of anti-cerebral ischemia.
Notes
- While adding with other essential oil it is better to use celery essential oil in moderation because it has very strong aroma which overpower other essential oil odour.
- The odour of the celery essential oil is quite obstinate and can overpower. It is not a bad idea to consider celery essential oil in aphrodisiac blends where it combines nicely with Cardamom.
- Celery essential oil has less limonene than the essential oil making it safer for skin applications. It is widely used in aromatherapy as calming oil which is good for the relief of tension headaches and it is an excellent anti-inflammatory in massage blends for arthritis, rheumatism, and muscle spasm relief. The combined anti-inflammatory and diuretic properties are recommended in a detoxification body wrap.
- In aromatherapy celery essential oil is used as an anti-inflammatory, anti-arthritic, anti-rheumatic, insomnia, muscle spasms, nervine, relaxation, aphrodisiac, carminative, detoxify, diuretic, headache, sedative and stress relief.
- Celery essential oil is widely used as a combination in massage oil, perfume, skin care, bath and body creams, lotions, gels, soap, candles and spa treatment oils. It is better to avoid during pregnancy or on breastfeeding mothers.
CO2 extraction process of celery seeds
Supercritical CO2 extraction is a widely used method for extracting celery seed oil from the seeds of the celery plant (Apium graveolens). Celery seed oil is known for its distinct aroma and various potential health benefits. Supercritical CO2 extraction offers several advantages over other extraction methods, including its ability to efficiently extract volatile compounds while maintaining their quality and minimizing the use of harsh solvents.
The five steps of CO2 extraction process of celery seeds
The process of supercritical CO2 extraction of celery seed oil typically involves the following steps:
- Preparation of Celery Seeds: The celery seeds are harvested from the celery plant and dried to an appropriate moisture level. Proper drying helps preserve the quality of the seeds and ensures optimal extraction efficiency.
- Loading the Extraction Vessel: The prepared celery seeds are loaded into an extraction vessel or chamber designed to withstand high pressure. The vessel is sealed to create a closed system.
- Extraction: Supercritical CO2 is introduced into the extraction vessel, where it acts as a solvent to extract the desired compounds, including the volatile constituents, from the celery seeds. The supercritical CO2 penetrates the seed matrix and selectively dissolves the target compounds, leaving behind non-volatile components.
- Separation: After the extraction process, the supercritical CO2 containing the dissolved compounds is transferred to a separation unit. Here, the pressure is reduced, causing the CO2 to revert to a gas phase. The celery seed oil, which is insoluble in gas-phase CO2, separates from the CO2 and is collected.
- Post-Processing: The collected celery seed oil may undergo further refining processes, such as filtration or distillation, to remove any residual impurities and obtain a pure and high-quality oil.
Top 4 Pros of CO2 Celery Seed Oil
- Efficient Extraction of Volatile Compounds: Supercritical CO2 extraction allows for the efficient extraction of volatile compounds from celery seeds, including the essential oils responsible for the distinct aroma and potential health benefits. The process preserves the delicate nature of these compounds, ensuring their retention in the extracted oil.
- Selective Extraction: Supercritical CO2 extraction offers selectivity in extracting the desired compounds while leaving behind unwanted components. The operating conditions, such as temperature and pressure, can be adjusted to optimize the extraction of specific compounds.
- Solvent-Free and Safe: Supercritical CO2 extraction is a solvent-free process that utilizes carbon dioxide as the extraction medium. CO2 is non-toxic, non-flammable, and widely recognized as safe for use in food and pharmaceutical applications. This eliminates concerns about residual solvent contamination in the final celery seed oil.
- Environmental Friendliness: Supercritical CO2 extraction is considered environmentally friendly as it reduces the use of harsh organic solvents and minimizes waste generation. CO2 used in the extraction process can be easily recycled and reused, contributing to a more sustainable extraction method.
Conclusion
Supercritical CO2 extraction is a highly effective and selective method for extracting celery seed oil, capturing its distinct aroma and potential health benefits. This extraction process allows for the efficient extraction of volatile compounds while maintaining the quality and purity of the final oil. With its solvent-free nature, environmental advantages, and ability to preserve the delicate volatile constituents, supercritical CO2 extraction is a preferred method for obtaining high-quality celery seed oil for various applications in the food, fragrance, and pharmaceutical industries.
