Table 1: Lipolysis extent. Molar percentages of triglycerides (TG), diglycerides (1-2-DG and 1,3-DG), monoglycerides (1-MG and 2-MG), and glycerol (Gol) in relation to the total glyceride structures in virgin flasseed oil samples (F), in the digestate of this oil (DF), and in the samples enriched in dodecyl galate, hydroxytrysool acetate, and gamma-tocopherol (DFCG\({}_{1}\), DFCG\({}_{2}\), DFHTA\({}_{1}\), DFHTA\({}_{2}\), DFY\({}_{1}\), DFY\({}_{2}\), DFY\({}_{3}\) and DFY\({}_{4}\)). Bioaccessibility of oil main components after in vitro digestion (B\({}_{\text{OMC}}\)), defined by the ratio (mol [FA] + [MG])\({}_{0}\)/mol ([FA] + [AG])\({}_{0}\). In contrast to this, and although the differences were not significant, a slightly smaller percentage of triglycerides, and a slightly higher percentage of glycerol in the digestates of the enriched samples than in the nonenriched sample was observed. This could suggest a slightly greater hydrolysis extent as a consequence of the enrichment in these phenolic compounds. In Vitro Bioaccessibility of Oil Main Components and Influence of the Enrichment with Different Phenolic Compounds  
The in vitro bioaccessibility of the main components of virgin flaxseed oil depends of both the extent and the pattern of lipolysis. As mentioned, of all the glyceryl species released during digestion, only fatty acids (FA) and monoglycerides (MG) are able to be absorbed by the intestinal wall. For this reason, the in vitro bioaccessibility of the oil main components is described by the ratio between the concentration of these absorbable species and all fatty acids (FA) plus acyl groups (AG) present in the corresponding digestate. This parameter is defined by the equation \(\text{B}_{\text{OMC}}=([\text{FA}]+[\text{MG}])_{\text{D}}\) /([FA]+[AG])\({}_{\text{D}}\), as in previous studies [14].
