Advanced Microbial Oil Purification Technology
Legal Citation
Background and Problem Solved
Microbial oil production has been hindered by inefficient purification methods, leading to inconsistent quality and reduced yields. The original patent (Microbial oil, production method for microbial oil, concentrated microbial oil, and production method for concentrated microbial oil) has limitations in terms of purification efficiency, fatty acid composition, and stability. The present invention addresses these limitations by introducing novel purification modules, multi-stage processes, and treatment methods to produce high-quality microbial oil with improved stability and polyunsaturated fatty acid content.
Novelty and Inventive Step
The present invention introduces novel purification conditions, multi-stage processes, and treatment methods that improve the efficiency, safety, and quality of microbial oil production. The inventive step lies in the combination of these elements to produce high-quality microbial oil with improved stability and polyunsaturated fatty acid content.
Alternative Embodiments and Variations
Alternative embodiments of the invention could include variations in the purification module design, different multi-stage purification processes, and alternative treatment methods for improving stability. Additionally, the invention could be adapted for use with different microbial biomass sources or integrated with existing production systems.
Potential Commercial Applications and Market
The invention has significant commercial potential in the production of high-quality microbial oil for use in food, pharmaceutical, and cosmetic industries. The improved efficiency, safety, and quality of the microbial oil production process make it an attractive solution for companies seeking to reduce costs and improve product quality.
