“…They are known to be an essential dietary requirement for humans and may also play a critical role in the economy of several countries (in Tunisia 1.7 million ha are planted with olive tree, producing 4% of the olive oil production worldwide; Jabeur et al, 2014). Given their economic value, adulteration with cheaper oils is a common problem (Salah and Nofal, 2021) sometimes resulting in serious effects on consumers health as in the case of the Spanish oil toxic syndrome (Gelpí et al, 2002). In this section, we will review the results of clinical studies carried out with the different commercially available edible oils.…”

Bioactive Compounds in Edible Oils and Their Role in Oxidative Stress and Inflammation

et al. 2021

Diet and inflammatory response are recognized as strictly related, and interest in exploring the potential of edible fats and oils for health and chronic diseases is emerging worldwide. Polyunsaturated fatty acids (PUFAs) present in fish oil (FO), such as eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), may be partly converted into oxygenated bioactive lipids with anti-inflammatory and/or pro-resolving activities. Moreover, the co-presence of phenolic compounds and vitamins in edible oils may prevent the development of chronic diseases by their anti-inflammatory, antioxidant, neuroprotective, and immunomodulatory activities. Finally, a high content in mono-unsaturated fatty acids may improve the serum lipid profile and decrease the alterations caused by the oxidized low-density lipoproteins and free radicals. The present review aims to highlight the role of lipids and other bioactive compounds contained in edible oils on oxidative stress and inflammation, focusing on critical and controversial issues that recently emerged, and pointing to the opposing role often played by edible oils components and their oxidized metabolites.

“…The quality of edible oil is closely related to public health and food safety and the choice of edible oils affects the nutritional balance of the human body [2]. However, the quality of edible oils is frequently subjected to adulteration, contamination, deterioration, and re-use problems in production process [3,4], which greatly affects their edibility. The external features of edible oils are easily tampered by physical and chemical means, it is more difficult to discriminate the quality of edible oils based only on color, smell, and taste [5,6].…”

The composition and content of fatty acids are critical indicators to identify the quality of edible oils. This study was undertaken to establish a rapid determination method for quality detection of edible oils based on quantitative analysis of palmitic acid, stearic acid, arachidic acid, and behenic acid. Seven kinds of oils were measured to obtain Vis-NIR spectra. Multivariate methods combined with pretreatment methods were adopted to establish quantitative analysis models for the four fatty acids. The model of support vector machine (SVM) with standard normal variate (SNV) pretreatment showed the best predictive performance for the four fatty acids. For the palmitic acid, the determination coefficient of prediction (RP2) was 0.9504 and the root mean square error of prediction (RMSEP) was 0.8181. For the stearic acid, RP2 and RMSEP were 0.9636 and 0.2965. In the prediction of arachidic acid, RP2 and RMSEP were 0.9576 and 0.0577. In the prediction of behenic acid, the RP2 and RMSEP were 0.9521 and 0.1486. Furthermore, the effective wavelengths selected by successive projections algorithm (SPA) were useful for establishing simplified prediction models. The results demonstrate that Vis-NIR spectroscopy combined with multivariate methods can provide a rapid and accurate approach for fatty acids detection of edible oils.

“…Morphological markers have limitations because they are only able to distinguish visual diversity. Therefore, other markers are needed to provide more accurate results, namely biochemical markers through the chromatography method (Salah and Nofal 2020).…”

Abstract. Habsyah TS, Basyuni M, Siregar LAM, Afandi D, Syahputra I. 2021. Distribution of polyprenol and dolichol in oil palm genotype (Elaeis guineensis) involving lipase activity. Biodiversitas 22: 830-837. The aim of this study was to determine the pattern of chemical compounds from the polyisoprenoid group in oil palm plants that were contributing to the lipase activity. The study was conducted in two locations. A sampling of leaves and fruit mesocarp from 90 progenies was conducted at PT. Socfin Indonesia Aek Loba Plantation, Asahan District, North Sumatra, Indonesia. Biochemical analysis of polyisoprenoid was carried out at the Forest Biotechnology Laboratory, Faculty of Forestry, University of Sumatera Utara, Medan. The results showed that the total lipids in leaves tissue ranged from 0.40 to 1.032 mg/g, with the lowest total lipid found in SL-4966 progeny and the highest total lipid found in SL-9737 progeny. Polyisoprenoid values ranged from 1.63 to 10.82 mg/g dry weight. The highest polyisoprenoid content was obtained in SL-10682 progeny, and the lowest was in SL-5045 progeny leaf tissue. The polyisoprenoid in fruit mesocarp tissue ranged from 1.79 to 4.14 mg/g. The lowest polyisoprenoid content (1.79 mg/g) of fruit mesocarp was found in SL-4233 progeny, while the highest (4.14 mg/g) was found in SL-5010 progeny. Dolichol and polyprenol are equally dominant in palm leaves. Carbon polyprenol chain lengths ranged from C45-C105, and dolichol ranged from C50-C110. The polyprenol carbon chain lengths in the mesocarp tissues were C65-C120 and dolichol was C65-C125. Polyisoprenoid analysis on oil palm leaf and fruit mesocarp tissue showed that lipid patterns of oil palm leaf and mesocarp were categorized as type II lipid patterns. It provides important information for selecting genotypes of low lipase activity of oil palm plants.
