Summary
Cassava flour quality degrades due to lipid changes during storage. This study reveals specific lipid alterations and affected metabolic pathways, offering insights for better storage technologies.
Area of Science:
- Agricultural Science
- Food Science
- Biochemistry
Background:
- Cassava is a vital global staple food for over a billion people.
- Lipid oxidation and deterioration during storage significantly impact cassava flour quality.
- Limited research exists on cassava flour's lipid composition and storage-related changes.
Purpose of the Study:
- To conduct a comprehensive lipidomic analysis of cassava flour during storage.
- To identify specific lipids and metabolic pathways affected by storage duration.
- To provide a scientific basis for improving cassava flour storage.
Main Methods:
- Utilized liquid chromatography-mass spectrometry/mass spectrometry (LC-MS/MS) for lipidomic profiling.
- Identified 545 lipids across five classes and 27 subclasses.
- Employed Metware Cloud for statistical analysis of lipid variations.
Main Results:
- Identified 545 lipids, including free fatty acids, diglycerides (DGs), and triglycerides (TGs).
- Observed significant variations in 50 lipid species over long-term storage.
- Found glycerolipid metabolism to be the most affected pathway, with storage-dependent metabolite differentiation.
Conclusions:
- Storage duration significantly alters the lipid profile of cassava flour.
- Specific lipid changes and affected metabolic pathways provide markers for storage time.
- Findings support the development of optimized storage technologies for cassava flour.
