Advanced Microbial Oil Purification Technology
Legal Citation
Background and Problem Solved
The original patent disclosed a microbial oil composition with high contents of arachidonic acid (ARA) and Mead acid. However, the production and purification process of the microbial oil had limitations, such as low yields and inefficient purification methods. The present invention addresses these limitations by introducing a novel rectification column with optimized temperature and pressure conditions, enabling real-time monitoring and control of the purification process.
Novelty and Inventive Step
The novelty of the present invention lies in the combination of the rectification column with optimized temperature and pressure conditions, and the real-time monitoring and control of the purification process. This invention provides a significant improvement over the original patent by enhancing the yield and quality of the microbial oil, while improving the efficiency and safety of the process.
Alternative Embodiments and Variations
Alternative embodiments of the invention may include different types of purification columns, such as packed columns or tray columns, and varying temperature and pressure conditions. Additionally, the invention may be adapted for use with different types of microorganisms or starting oils.
Potential Commercial Applications and Market
The invention has significant commercial potential in the food, pharmaceutical, and cosmetic industries, where high-quality microbial oil is in high demand. The improved yield and quality of the microbial oil, combined with the enhanced efficiency and safety of the process, make this invention an attractive solution for companies seeking to produce high-value products.
