“…The general properties of the enriched oil (Table ) are almost identical to those we reported recently for oil glycerolysis with refined glycerol using heterogeneous catalysis (Ferretti et al, ). Our 1,3‐DAG content is also comparable to those of solvent‐free enzymatic oil glycerolysis with refined glycerol (33–40 wt.%) (Kristensen et al, ; Zhang et al, ) and lower than those reported for oleic or lauric acid enzymatic esterification with refined glycerol (>80 wt.%) (Zhao et al, ; Zhong et al, ). However, regarding the latter, fatty acids are not naturally available and must be obtained previously by oil hydrolysis.…”

Commercial edible vegetable oils in which part of their triglycerides are substituted with 1,3-diglycerides are healthier for human consumption than the original oils. This is because the human metabolism of 1,3-diglycerides is believed to occur through a distinct pathway with less probability of being deposited as fat in the body tissues. To obtain these enriched oils, conversion of triglycerides into diglycerides is carried out by glycerolysis using commercial crude glycerol containing dissolved alkali cations that homogeneously catalyze the reaction. The addition of a food production-compatible MgO as a supplementary solid basic catalyst, shortens the reaction time by half due to a combination of homogeneous and heterogeneous catalysis processes. In either homogeneously or homogeneousheterogeneously catalyzed glycerolysis, the increase of the reaction temperature in the range of 453-493 K increases the final 1,3-diglyceride content. Furthermore, in both glycerolysis processes the triglyceride content can be decreased in more than 60% with the consequent increase of total diglycerides to 50%, 70% of which are the 1,3-isomers. The glycerolysis reaction proceeds without altering the fatty acid distribution of the original oils.

“…410 Diacylglycerol-enriched soybean oil was produced via glycerolysis of soybean oil catalyzed by N435 in a solvent-free system using a modified bubble column reactor. 411 Almost 50% diacylglycerol content was obtained and the enzyme can be reused in 10 cycles. Sardine oil was subjected to glycerolysis to produce mono and diglycerides rich in unsaturated fatty acids using supercritical CO 2 and organic solvents.…”

“…While TAG crystallization produces a volume contraction associated with an exothermic transition, melting yields a volume expansion, characterized by an endothermic process. The thermal profiles of lipids could be complex due to their complex TAG compositions, as well as because of their polymorphism. − DSC from soybean oil (Figure S1) is an example of this complex behavior, which is widely investigated in the literature. − …”

Blends of fully and partial hydrogenated soybean oil, with 50/50 and 80/20 wt %, were chemically interesterified. The composition−texture relationships were investigated and established for the set of investigated materials. The raw materials, the original and interesterified blends, were analyzed in terms of their fatty acid and triacylglycerol compositions by gas chromatography. All materials were characterized by differential scanning calorimetry (DSC), polymorphic forms were characterized by X-ray diffraction (XRD), crystalline structures were characterized by polarized light microscopy (PLM), and textures were characterized by penetration testing. Interesterification caused a rearrangement of triacylglycerol species, reducing the concentration of trisaturated, triunsaturated, and diunsaturated triacylglycerols, increasing the amount of monounsaturated triacylglycerol, and resulting in a lowering of melting points as compared with the original blends. This modification in the chemical composition clearly changed the crystallization behavior, producing reductions in crystal size, alterations in crystalline polymorphism, and increases in plasticity in the blends. Interesterified materials displayed melting and textural characteristics suited for potential mineral wax substitutes.
