- The first study on β-cyclodextrin/Danube fish oil complexation was performed.
- Moisture content of β-cyclodextrin/Danube fish oil complexes was evaluated.
- Significant correlations for moisture-related TG-DSC parameters have been obtained.
- Danube fish oil composition influences the water behavior of complexes.
The moisture content of β-cyclodextrin/Danube fish oils complexes (common barbel, Pontic shad, European wels catfish, common bleak) was evaluated by thermal methods. Saturated and monounsaturated fatty acids were the most concentrated in fish oils (25.3-30.8% and 36.1-45.0%). Ï-3 And Ï-6 fatty acids were identified in low concentrations of 2.8-12.1% and 4.1-7.1%. The moisture content was significantly lowered after β-CD complexation, as revealed by thermogravimetric (TG) analysis (13.3% for β-CD, 2.5-6.5% for complexes). These results are consistent with the differential scanning calorimetry (DSC) data for the peaks corresponding to dissociation of water (calorimetric effect of 536 J gâ1 for β-cyclodextrin and 304-422.5 J gâ1 for complexes). Furthermore, both TG and DSC results support the formation of inclusion complexes. This is the first study on the nanoencapsulation of Danube fish oils in β-cyclodextrin.
