Effect of the Enrichment of Corn Oil with - or -Tocopherol on Its Digestion Studied by H NMR and SPME-GC/MS; Formation of Hydroperoxy-, Hydroxy-, Keto-Dienes and Keto--epoxy--Monoenes in the more -Tocopherol Enriched Samples. | LitMetric
The aim of this study is the analysis of the digestion of corn oil, and of the effect of its enrichment with three levels of - and -tocopherol, by using, for the first time, H nuclear magnetic resonance (H NMR) and a solid phase microextraction followed by gas chromatography/mass spectrometry (SPME-GC/MS). The attention is focused on the hydrolysis degree, the degradation of oil's main components, the occurrence of oxidation reactions and main compounds formed, as well as on the bioaccessibility of oil's main components, of compounds formed in the oxidation, and, of - and -tocopherol. The lipolysis levels reached are high and show a similar pattern in all cases. The oxidation of corn oil components during digestion is proven, as is the action of -tocopherol as an antioxidant and -tocopherol as a prooxidant. In the more -tocopherol enriched samples, hydroperoxy-, hydroxy-, and keto-dienes, as well as keto-epoxy-monoenes and aldehydes, are generated. The bioaccessibility of the oil's main components is high. The compounds formed in the oxidation process during digestion can also be considered bioaccessible. The bioaccessibility of -tocopherol is smaller than that of -tocopherol. The concentration of this latter compound remains unchanged during the digestion of the more -tocopherol enriched oil samples.
This study examined the possible defensive role of coenzyme Q10 (CQ10) against the impact of cadmium (Cd) and titanium dioxide nanoparticle (TNP) exposure on rat kidneys. Distilled water (1 mL/rat), corn oil (1 mL/rat), 10 mg CQ10/kg b.wt, 50 mg TNP/kg b.

: The beneficial effects of ω-3 fatty acids on the cardiovascular system have been observed in many epidemiological studies; however, their effects on the skeleton and in particular on postmenopausal bone loss appear to vary. The present study's purpose was to investigate the effects of oral fish oil (rich in ω-3 fatty acids) consumption on bone, plasma, and inflammation parameters in the ovariectomized (Ovx) rat model of osteopenia. : Four Groups of ten rats each were separated into Non-Ovx receiving fish oil (2.
In this study, thymol-loaded nanoemulsion (THYNE) was incorporated into a mixture of egg white protein and hyaluronic acid to prepare antibacterial biopolymer coatings. The oil phase of the nanoemulsion (NE) was prepared by mixing different mass ratios of thymol and corn oil. NE was formed using ultrasonic emulsification, and the physicochemical properties of the NE were investigated.
The objective of this study was to investigate the effects of retrograded resistant starch (RS3) (0, 2%, 4% and 6%; /) on the emulsion gel properties stabilized by myofibrillar proteins (MPs) and in vitro protein digestibility of the gels. The RS3 was prepared from corn or potato starch using the gelatinization-ultrasound-retrogradation method. The results showed that the addition of RS3 decreased the surface hydrophobicity ( < 0.
