Brassica napus L., the third most important oil crop in the world after maize and oil palm, has a unique history among those crops that are targets of breeding and genetic modification. Effective tools of processing, biotechnology, and agronomy are essential to produce rapeseed oil with a high amount of bioactive compounds and continue to be employed in strengthening the product versatility.

Of the table olives and olive oils already registered with Protected Designation of Origin (PDO), there are eight products belonging to the five main regions of Portugal (Trás-os Montes, Beira Litoral, Beira Interior, Ribatejo, and Alentejo). Furthermore, these PDO products are linked to the history and cultural heritage of these places, being crucial for some local producers and for consumers.

Oregano, laurel, and rosemary essential oils can be used as antioxidants in peanut products and foods with high lipid content.

The fatty acid composition of microalgae has been proven as a potential tool for the identification of microalgal taxa. Application of fatty acid composition as a fingerprinting tool requires fast, reliable, and precise methods. A rapid and routine direct transesterification method for the evaluation of the fatty acid composition of microalgae biomass is presented in this paper. The transesterification is being done in two steps as sonication assisting base-catalyzed methanolysis followed by BF3 methylation reactions. Heating in boiling water bath for 2 min is required at both steps to improve the reactions.

The pseudo ternary phase diagram method is used to screen the optimum composition of liquid self-emulsification delivery system. Then, this liquid system is converted into solid state using the solid absorbent carrier by simple physical mixing.

A flash gas chromatography electronic nose (FGC E-nose) is applied to measure flavor quality changes and monitor the oxidation process of rapeseed oils during frying. Partial least squares regression is applied to determine the relationship between total polar compounds and some volatile compounds determined by FGC E-nose in frying rapeseed oils.

The effect of ultrasound technology parameters is investigated from the point of phenolic compounds by searching their relation to enzymes in Chemlali and Memecik cvs. olive paste. In addition, the effects of stone removal during extraction are also studied in terms of enzymes in Chemlali and Memecik cvs. olive paste and phenols in olive oil.

The gap of 68 amu between the molecular ion (333) and m/z 265 indicate the location of cyclopentyl ring at C14, which is first determined in heated soybean oil.

A comprehensive characterization of edible vegetable oils mechanically extracted from the mesocarp of fresh Acrocomia aculeata fruit is carried out to consider the assessment of different temperature conditions and subsequent pressings. Quality, composition, and identity characteristics of the crude oil are obtained to set up standards also on health-related topics.

The seed oils of Apiaceae species contain a variety of specific phytochemicals. The most common fatty acid is petroselinic acid, with 2-methoxyethyl esters known to allow quantification of this acid. The mass spectra of fatty 2-methoxyethyl esters are reported.

Compositional shift among total PL subclasses and neutral lipids.

Consumption of poly unsaturated fatty acid fortified soy yogurt results in a significant reduction in the liver total cholesterol of hypercholesterolemic mice when compared with soy yogurt (control) only.

Enzymatic production of structured TAGs enriched in EPA and DHA is done in a two-step reaction from a natural source of omega-3 ALA, camelina oil, studying reaction kinetics and characterizing isolated products.

The VesiCAT assay may represent a routine test for antioxidant ranking, with additional information regarding the antioxidants distribution and the evaluation of their capacity to interact with oxidant species in different cell regions.

This study evaluates the influence of supplementation of rats’ diet with pomegranate seed oil separately or jointly with bitter melon extract on fatty acid, cholesterol, malondialdehyde, and tocopherols concentrations in femoral muscles. After 21 weeks of supplementation, muscles are subjected to either gas or liquid chromatographic analyses. Supplementation of diet with pomegranate seed oil decreases cholesterol and malondialdehyde contents.

The aroma-active compounds of Moroccan argan oil are sensorily and instrumentally analyzed via gas chromatography-mass spectrometry-olfactometry (GC-MS-O). The purge and trap extraction (PTE) method is used for the extraction of volatile components. A total of 19 aroma compounds are detected as aroma active by AEDA method among 35 volatiles. Characteristic odor notes in argan oil are found to be roasty, nutty, fatty, earthy, and cheesy.

A method based on EC changes in the aqueous phase extracted from water–oil mixture is used to determine the extent of edible oil oxidation. At a water–oil (v/v) ratio of 5, the EC model can be divided into three regions: ECs of less than 6.9 µS cm⁻¹ representing non-oxidized oils, ECs within 6.9–8.9 µS cm⁻¹ representing suspected oils, and ECs of over 8.9 µS cm⁻¹ representing oxidized oils. The total identification rate of the model in validation samples is 94.1%.

The antioxidant potential of pitanga leaf extracts, including UPLC-DAD-MS/MS phenolic profile, antioxidant activities, and their effects on canola oil stability after accelerated storage conditions, are evaluated.

Evalution of oxidative markers under accelerated conditions in crude and stripped flaxseed oil treated with hydrophilic antioxidant mixture (HM) and lipophilic antioxidant mixture (LM), comparing the effectiveness with artificial antioxidant mixture (ART), to choose the best mixture for food industry application. It can be observed that HM improved oxidative stability in crude oil while LM improve oxidative stabilty for stripped oil. This could be explained by the presence or absence of minor componentes.

The use of protease from seabass pyloric caeca in combination with repeated freeze-thawing cycles increases the production efficiency of virgin coconut oil.

Both docosahexaenoic acid – phosphatidylcholine (DHA-PC) forage and liposome shows benefits in alleviating Alzheimer's disease development in senescence-accelerated prone 8 mice by inhibiting β-amyloid generation, oxidative stress, apoptosis, neural inflammation, and enhancing neurotrophins pathway in different degrees.

Our preliminary study investigates the changes in intramuscular phospholipid (PL) composition in beef and venison after postmortem aging. Postmortem aging decreases the phospholipid levels in meats. The 20:4n-6 is released from the meat phospholipid during postmortem aging. The two above-mentioned are considered due to hydrolyzation of the diacylglycerophospholipids in meats. The hydrolysis of phospholipid may depend on meat cuts and breed.

The physicochemical characterization of stigmas from the non-sterile Crocus serotinus plant indicates their potential as alternative sources of the bioactive crocetin, a lipophilic apocarotenoid that is primarily obtained from the secondary metabolites of C. sativus plant stigmas, known as saffron.
