Partition of lipids in the different classes in SF of FO after digestion with or without capsules, evaluated by TLC-FID.
| Not Digested | SF (Digested w/o Capsule) | SF (Digested with Capsule) | p-Value | |
|---|---|---|---|---|
| WEs | 4.19 ± 3.84 a | 0.85 ± 0.81 a (1.38%) | 3.49 ± 4.93 a (5.32%) | 0.55 |
| TAGs | 88.84 ± 3.32 a | 15.57 ± 1.49 b (25.31%) | 12.22 ± 1.55 b (19.20%) | <0.001 |
| FFAs | 2.00 ± 2.83 a | 10.95 ± 0.90 a (17.80%) | 26.26 ± 19.94 a (42.08%) | 0.25 |
| ALCs | 1.90 ± 2.68 | n.d. | n.d. | |
| DAGs | 1.12 ± 1.58 a | 9.53 ± 1.60 a (15.49%) | 7.13 ± 4.21 a (11.08%) | 0.10 |
| AMPLs | 1.59 ± 0.57 a | 21.58 ± 3.05 a (35.08%) | 10.08 ± 9.58 a (15.54%) | 0.09 |
| PLs | 0.36 ± 0.50 a | 3.02 ± 1.50 a (4.91%) | 4.36 ± 2.57 a (6.78%) | 0.19 |
Data are expressed as mg/100 mg of not-digested oil and are means ± SD of 2 replicates. Statistical analysis was performed by Student’s t-test when comparing two values and by one-way ANOVA with Tukey’s test as post-test when comparing three values. p < 0.05 was considered significant. Different letters in the same row indicate statistical significance. The mean percentage contribution of each class to total lipids in SF is reported in parentheses. SF = soluble fraction; WEs = sterol esters and wax esters; TAGs = triglycerides; FFAs = free fatty acids; ALCs = free aliphatic alcohols; DAGs = diglycerides; AMPLs = acetone-mobile polar lipids; PLs = phospholipids and other acetone immobile polar lipids; n.d. = not detectable.
