Data are given as mean ± standard deviation. Discrete lowercase letters (a–d) in the same row are used to explain statistical differences (p < 0.05). SSF: Simulated saliva fluid. SGF: Simulated gastric fluid. SIF: Simulated intestinal fluid. H2: Hydrogel containing essential oil alone. HNL1: Hydrogel containing NL1 lecithin: 0.20 M; essential oil to total oil (%): 14.23). HNL2: Hydrogel containing NL2 (molar ratio of lecithin to maltodextrin: 0.80; essential oil to total oil (%): 20). HNL3: Hydrogel containing NL3 (molar ratio of lecithin to maltodextrin: 0.40; essential oil to total oil (%): 25). HNL4: Hydrogel containing NL4 (molar ratio of lecithin to maltodextrin: 0.20; essential oil to total oil (%): 33.33). nd: not detected.
