Since the quality and safety of food highly depend on its preservation and protection, the use of food packaging materials increases the risk of chemical contamination of the packaged food by migration. Herein, we focused on antioxidants, photoinitiators, UV absorbers and plasticizers which are extensive additives used in food packaging materials. In the present study, a rapid, simple, green and reliable method was developed and validated for the determination of twelve chemical additives in edible vegetable oils using SFC together with a modified QuEChERS procedure. Under the optimum conditions, twelve additives were separated within 10 min, and the consumption of the organic solvent was significantly reduced, which improved the environmentally friendliness. The performance of the developed method was evaluated. Good linearity (r > 0.999) was obtained in the range of 0.20–20.0 µg/mL and 0.50–20.0 µg/mL, respectively. The limits of detection and limits of quantification of the twelve additives in vegetable oils were 0.05–0.15 µg/mL and 0.15–0.50 µg/mL, respectively. Recoveries of all the chemical additives for the spiked samples were between 60.9% and 106.4%, with relative standard deviations (RSD) lower than 9.9%. The results demonstrated that the proposed method was efficient, reliable and robust for the routine analysis of additives in edible vegetable oils and can be an alternative to the multi-residue analysis of chemical additives for other packaged foods.Keywords:antioxidants;photoinitiators;UV absorbers;plasticizers;edible vegetable oils;QuEChERS;supercritical fluid chromatography

A new route to synthesize a covalent interaction-based molecularly imprinted polymer (MIP) material for 3-chloro-1,2-propanediol (3-MCPD) inside the nanopores of anodic alumina oxide (AAO) is presented. A series of adsorption experiments showed MIP had good extraction capacity and selectivity for 3-MCPD. In order to evaluate the usability of the MIP nanotubes membrane, a method combining AAO@MIP membrane extraction with gas chromatography – mass spectrometry (GC–MS) detection was developed for determination of chloropropanols. The limits of detection for the proposed method were 0.072 and 0.13 µg·L −1 , respectively, for 3-MCPD and 1,3-DCP. The average recoveries of 3-MCPD and 1,3-DCP spiked oil samples at three concentrations (0.01, 0.05 and 0.1 mg·kg −1 ) were in the range of 75.6–101.0% with a RSD of 3.3–8.4%, indicating the method would be suitable for determination of chloropropanols in vegetable oils.

A simple, rapid and accurate method was developed to quantify DAGs by UHPLC-MS/MS. • Florisil SPE sorbent was used to extract and purify DAGs in lipid samples. • The SPE procedure could be achieved in 30 min with less volume of organic solvents. • All anaytes were chemical labelled under mild conditions with high efficiency. • The proposed method was used for the determination of DAGs in complicated matrices. s In the present study, a simple, accurate and simultaneous determination of diacylglycerol (DAG) compounds in vegetable oils were proposed by solid-phrase extraction (SPE) coupled with chemical labelling-based UHPLC-MS/MS. The experimental conditions of SPE purification, chemical labelling and UHPLC-MS/MS were investigated. Under the optimized parameters, the limit of quantification ranged from 4 μg kg -1 to 25 μg kg -1 , and the limit of detection ranged from 1 μg kg -1 to 7 μg kg -1 . Acceptable recoveries of all analytes were obtained ranging from 67.4% to 106.1% with the intra-day and inter-day precisions less than 14.8%. The validation results indicated that nine 1,3-DAG compounds were found at the concentration ranging from trace level to relative high amount in four types of edible oils. The proposed method simultaneously analyzed 16 DAG compounds in complicated matrix and accurately profiled the content and distribution of functional components in vegetable oils.

Aflatoxin-contaminated vegetable oils pose severe threats to human health. Although magnetic graphene-based materials can be used for aflatoxins (AFs) removal, their current preparation methods involve complex, multi-step procedures and are time-consuming. Herein, we proposed a simple, efficient and solvent-free mechanochemical approach for one-step synthesis of magnetic graphene composite (MGC) directly from graphite and Fe 3 O 4 . The MGC was used as an adsorbent to remove four AFs from vegetable oils, and the adsorption mechanism was further explored by conducting batch adsorption experiments. The results demonstrated that MGC could simultaneously remove 85.8–100 % of AFs from 13 types of oils within 60 min at 30 °C. The detoxification process exhibited low cytotoxicity towards HepG2 cells, and has little effect on the quality of oils. Thus, MGC exhibited promising application potential for vegetable oil detoxification in food industry due to its facile scalable production, efficient detoxification capability, good biosafety, and easy recovery and regeneration.

Liquid chromatography‒mass spectrometry employing porous graphite carbon columns and an n-octane-isopropanol mobile phase was utilized for the separation of triacylglycerols (TAGs) in various edible oils, aiming to identify lard adulteration in soybean, corn, and sunflower seed oils. Experiments were conducted using a Hypercarb column (2.1 mm × 100 mm, 5 µm) and an n-octane-isopropanol (70:30, V/V) mobile phase at a flow rate of 0.25 mL· min −1 and a column temperature of 60 °C. Detection was achieved through atmospheric pressure chemical ionization-mass spectrometry. Analysis of diverse edible oil samples revealed that oils of the same type shared similar TAG compositions, while different types exhibited distinct TAG profiles. Distinct variations in triglyceride composition were observed across different edible oils. Based on liquid chromatography‒mass spectrometry analysis, the characteristic component 1-stearic acid-2-palmitic acid-3-oleic acid glyceride (SPO), which may also include PSO, was identified in lard through principal component analysis and orthogonal partial least squares discriminant analysis. This component served as a marker for detecting as low as 0.1% lard adulteration in soybean, corn, and sunflower seed oils. The technique offers a precise and effective approach for the identification of lard adulteration in these edible oils. Graphical abstract

Replacing animal fat with vegetable oil occurred extensively in the meat products, but whether these replacements will affect the nutrition of meat protein was seldom revealed. Effect of substitution of back fat (BF) by vegetable oils or their oleogels in emulsion-type sausage on the digestion process of meat protein was investigated. Replacement of BF with vegetable oils and their oleogels decreased the G'/G" values of meat paste, and oleogels largely weakened the structure of sausages. The substitution significantly reduced the liberation of -NH 2 during the initial gastric and intestinal digestion, and resulted in bigger digests in CLSM images. The reduced gastric digestibility induced by substitution was shown to be related to the reduced stability of gastric digests, which can be attributed to the larger particle size and reduced viscosity of digests. These results highlighted stability of digests as a key point changing the digestion process of meat protein.

A fast, simple, and sensitive analytic method was proposed for the simultaneous quantification of aflatoxins (AFTs) and capsaicinoids in vegetable oils by immunomagnetic sorbent coupled with ultra-performance liquid chromatography coupled with tandem mass spectrometry. The immunomagnetic solid phase extraction (IMSPE) sorbents were synthesized with the monoclonal antibodies via cyanogen bromide magnetic sorbents, which could modify the surface magnetic sorbents under mild synthetic condition. The IMSPE procedure had the following aspects such as ease manipulation, easy disperse, quick isolation, eco-friendly, and cost-effective. The major conditions of IMSPE procedure were systemically studied, and the optimized pretreatment was accomplished in 15 min avoding complicated condition or sophisticated equipment. Excellent linearities were achieved by the correlation ( R 2 ) more than 0.9983. The limits of quantifications of all analytes ranged from 0.03 to 0.20 µg kg −1 , and the recoveries were satisfactory ranging from 75.7% to 124.0% with the intra-day and inter-day precisions less than 10.1%. Additionally, the proposed method was used to analyze AFTs and capsaicinoids in retail oil samples. Overall, 25% of soybean and peanut oils and 12.5% of corn and blended oil were detected with AFTs, and no capsaicinoid was found. The content of AFTs was under the MRLs set by EU and China regulation for food quality and safety. The validated results indicated that this method could be utilized for a rapid, efficient, and accurate quantification of AFTs and capsaicinoids in complex lipid-based matrix.

3-Monochloropropanediol esters (3-MCPDEs) and glycidyl esters (GEs) with high toxicity have drawn global concerns due to their widespread occurrence in refined oils and oil-based foods . The effect mechanisms of organic chlorine compound lindane, inorganic chlorine compounds tetra- n -butylammonium chloride (TBAC) and sodium chloride (NaCl) on the formation of 3-MCPDEs and GEs were investigated in model oils and chemical models at 240 °C. Results showed that 3-MCPDEs contents increased with the addition of lindane and TBAC, whereas, surprisingly, GEs presented the same tendency as the results of 3-MCPDEs. This suggested that although chlorine compounds were not involved in the formation reaction of GEs, they could also promote GEs formation. Chemical model experiments confirmed that the presence of chlorine compounds led to the transformation of GEs to 3-MCPDEs and conversely 3-MCPDEs could also transform to GEs. The latter transformation rate from 3-MCPDEs to GEs was higher than the former, which might account for the fact that chlorine compounds promoted GEs formation. Additionally, it was also observed that solid NaCl did not induce the increase of 3-MCPDEs and GEs levels in chemical models, suggesting that the chlorine in NaCl, different from lindane and TBAC, was not available for 3-MCPDEs formation. The present findings give novel insights into the interactions between 3-MCPDEs and GEs formation mechanisms, which offer the theoretical basis for efficient and simultaneous inhibition of 3-MCPDEs and GEs.

A hybrid composite featuring an iron-based metal-organic framework Material of Institute Lavoisier-88(Fe) and graphene oxide (MIL-88(Fe)/GO) was synthesized and used as the solid-phase microextraction (SPME) coating. The SPME fiber was prepared by covalent bonding of the MIL-88(Fe)/GO composite onto the stainless steel substrate. The fiber had a good durability and allowed >100 replicate extractions. The developed method, which combined the MIL-88(Fe)/GO coated fiber based SPME with gas chromatography-flame ionization detection (GC-FID), achieved low limits of detection (0.5–2.0 ng g −1 , S/N = 3) and good linearity ( r 2 > 0.994) for the phthalic acid esters (PAEs) from various vegetable oil samples. The repeatability and fiber-to-fiber reproducibility were in the range of 4.0–9.1% and 5.7–11.4%, respectively. The method was successfully applied to the analysis of PAEs from vegetable oil samples with good recoveries (83.1–104.1%) and satisfactory precisions (RSDs < 10.5%), indicating that the MIL-88(Fe)/GO hybrid composite is a good coating material for the SPME of PAEs.

The formation of three toxic reactive aldehydes, malondialdehyde (MDA), 4-hydroxy-hexenal (HHE), and 4-hydroxy-2-nonenal (HNE), is investigated in five commonly consumed vegetable oils using a method based on the Schaal oven test. HHE is only detected in linseed oil (LO) and rapeseed oil (RO), while MDA and HNE are found to be present in all tested oils. The formation potential of MDA, HHE, and HNE in the tested oils is closely related to the initial polyunsaturated fatty acid (PUFA) content in the oil. Correlation analyses reveal low correlation coefficients for MDA, determining its unsuitability to evaluate the oxidation of oils with low PUFA content, such as palm oil and camellia oil; in contrast, HHE and HNE show sufficient correlations with other oxidation indices in all tested oils. Furthermore, regression analysis indicates that HHE content can predict the oxidation of ω-3 type oil, while HNE content can estimate oxidative deterioration of ω-6 type oils. Particularly, HNE content can also evaluate the oxidation of ω-9 type oils such as PO and CLO with relatively low PUFA level for the high correlations (>0.991, P < 0.01) toward the total oxidation value (TOTOX). Practical Applications : Edible oil consumption continues to increase worldwide. Therefore, it is very important to understand the conditions under which potentially health-damaging compounds are formed in these oils and to develop methods to inhibit their formation or eliminate them from the oils. This study investigates the formation of three toxically reactive aldehydes, namely MDA, HHE, and HNE, through lipid oxidation, specifically PUFA peroxidation. The application of these aldehydes as oxidation indicators for different vegetable oils is also explored. This work could prove beneficial for the quality control of vegetable oils in the edible oil industry. The formation of three toxic aldehydes, MDA, HHE, and HNE in different types of vegetable oils is investigated. Considerable amounts of MDA, HHE, and HNE is found in all the tested oils. The results show the formation of these three aldehydes is competitive. Besides, MDA content is not appropriate to evaluate the oxidation of oils with low PUFA content, such as PO and CLO; while HHE and HNE can characteristically depict the oxidation of ω-3 and ω-6 type oil.

Vegetable oils with different unsaturated degrees (corn > peanut > olive > palm > coconut) and corresponding enzymatic hydrolysis-thermal oxidation (ENTH) oils were added into D-xylose and L-cysteine Maillard reaction (MR) system, respectively, for potential meaty aroma production. Results indicated that coconut oil and palm oil had lower peroxide, p -anisidine, total antioxidant values, and malondialdehyde content after ENTH and MR. Corn, peanut, and olive oils after ENTH could significantly promote MR because they caused the lower pH, higher reactants depletion, and higher browning degree in the water phase separated from the oil-Maillard reaction system. Additionally, the volatiles were mainly formed from oil phase. Corn, peanut, and olive oils were beneficial to volatiles formation in the oil-MR system due to fatty acid oxidation, especially oleic acid and linoleic acid. Meanwhile, compared to raw oils, adding ENTH oils to the MR system could reduce the content of oxygen, nitrogen, and sulfur-containing heterocycles.

Authentication of walnut oil (WO) is challenging due to the adulteration of high-linoleic acid vegetable oils (HLOs) with similar fatty acid composition. To allow the discrimination of WO adulteration, a rapid, sensitive and stable scanning method based on supercritical fluid chromatography quadrupole time-of-flight mass spectrometry (SFC-QTOF-MS) was established to profile 59 potential triacylglycerol (TAGs) in HLOs samples within 10 min. Limit of quantitation of the proposed method is 0.002 µg mL −1 and the relative standard deviations range from 0.7% to 12.0%. TAGs profiles of WO samples from various varieties, geography origins, ripeness, and processing methods were used to construct orthogonal partial least squares-discriminant analysis (OPLS-DA) and OPLS models that were highly accurate in both qualitative and quantitative prediction at adulteration levels as low as 5% (w/w). This study advances the TAGs analysis to characterize vegetable oils and holds promise as an efficient method for oil authentication.
