- Novel steps in sequential processing to achieve lipid structuring
Key Points:
| Claim Focus |
Details |
| Reaction Type |
Enzymatic interesterification, chemical interesterification, or combined processes |
| Reaction Conditions |
Temperatures typically ranging between 40–90°C, specific catalyst concentrations, specific reaction durations |
| Product Intermediates |
Lipid intermediates with defined fatty acid positional distribution |
B. Product Claims
While primarily process-oriented, the patent also claims structured lipids characterized by:
| Feature |
Description |
| Fatty Acid Composition |
Specific ratios of saturated, monounsaturated, and polyunsaturated fatty acids |
| Physical Properties |
Melting point, crystallinity, and digestibility characteristics |
| Structural Specificity |
Positional distribution of fatty acids on glycerol backbone processes |
Note: Product claims tend to be narrower, focusing on formulations produced by the claimed process.
C. Territorial Scope
The patent is filed through WIPO under the Patent Cooperation Treaty (PCT), with potential national phase filings in key jurisdictions such as:
