Foodomics Revealed the Effects of Extract Methods on the Composition and Nutrition of Peanut Oil

Abstract

Processing technology has a significant effect on the functional quality of vegetable oil, but the exact mechanism is not yet very well known so far. The purpose of this study was to investigate the effects of extract methods on the composition and nutrition of peanut oil. Peanut oil was prepared by cold pressing, hot pressing, and enzyme-assisted aqueous extraction, and their trace components were determined by liquid chromatography–mass spectrometry (LC–MS). Serum and liver samples from Sprague–Dawley (SD) rats fed with different extract oils were profiled by gas chromatography–mass spectrometry (GC–MS) and LC–MS. The component analysis showed that different process technologies cause differentiation of trace active ingredients. Metabolomics analysis revealed that a high-fat diet causes serum and hepatic metabolic disorders, which can be ameliorated by hot-pressed and hydroenzymatic peanut oil, including downregulation of partial amino acids, fatty acids, phospholipids, and carbohydrates in cold-pressed peanut oil as well as the upregulation of palmitic acid, uric acid, and pyrimidine in enzyme-assisted aqueous oils. Canonical correspondence analysis (CCA) uncovered strong associations between specific metabolic alterations and peanut oil trace components. The data obtained in this study offers a new insight on the roles of oil processing.

Comparison of the effect of extraction methods on the quality of green coffee oil from Arabica coffee beans: Lipid yield, fatty acid composition, bioactive components, and antioxidant activity

“…Heat maps have become an efficient tool for the evaluation of agricultural product quality and can reflect the chemical composition differences of samples prepared by different preprocessing methods [35] , [21] . In this study, to investigate the differentiating power of the indexes used, HCA was performed with 24 analytical indexes, and a heat map was utilized to exhibit alterations of chemical indexes in the four kinds of samples using Euclidean distance as a similarity measure.…”

Metabolomics reveals the impact of the saturation of dietary lipids on the aging and longevity of C. elegans

“…The GC-MS assay was based on a previous method from our laboratory. 37 In brief, the samples were injected into the HP-5MSI column by a batch autosampler system and analyzed by the GCMS-QP2020 system. The temperature of the injection port was 250 °C, and helium was used as the carrier gas at the flow rate of 1.0 mL min −1 .…”

Management Accounting for Healthy Nutrition Education: Meta-Analysis

“…Assessment of the impact of the consumption of products/services of any kind in nature, and its measurement based on the ecological footprint. This is an environmental indicator of the impact that a community, country, region or city has on its surroundings [131,132]. For food, the ecological footprint is expressed as the area necessary to produce the resources consumed by any activity, in addition to that necessary to absorb the waste it generates, regardless of its location [133].…”
