Improved sustainable ionic liquid catalyzed production of symmetrical and non ‐symmetrical biological wax monoesters
AbstractBiological wax esters are important commercial products used in various industrial and medicinal fields. These valuable compounds can be synthesizedvia several chemical and enzymatic reactions which have some advantages and more disadvantages. In particular, many strong acid catalysts cause undesirable structural changes in unsaturated fatty acids molecules. In the present study easily accessible 1 ‐hexadecyl‐3‐sulfoimidazolium chloride as ionic liquid was screened as a mild Brønsted acid metal free catalyst for the chemical esterification or transesterification of equimolar amounts of long chain fatty acids...

Extraction of oil from high ‐moisture tuna liver by subcritical dimethyl ether: a comparison with different extraction methods
In this study, subcritical dimethyl ether extraction (SDEE) was applied in the extraction of oil from high‐moisture tuna liver. Besides, other different extraction methods including wet reduction (WR), enzymatic extraction (EE), an d supercritical carbon dioxide fluid extraction (SFE‐CO2) were used for comparisons, to assess the effect of different extraction methods on yield, oil quality, flavour (volatile compounds and sensory assessing), vitamin contents and fatty acids composition. Compared with traditional methods, the high ‐quality liver oil could be obtained with excellent yields by SDEE and SFE‐CO2, because...

Evolution of safety and other quality parameters of the Greek PDO table olives ‘Prasines Elies Chalkidikis’ during industrial scale processing and storage
AbstractThe evolution of safety and other quality parameters of the Greek green table olives PDO ‘Prasines Elies Chalkidikis’ that are prepared according to the Spanish style processing was examined systematically at industrial scale and 12 month storage for two consecutive periods for the first time. Evolution of safety parameters (bacteria/yeasts, pH, acidity) during fermentation in brine and on olives upon storage, changes in olive color and texture during storage and the fate of characteristic hydrophilic and hydrophobic antioxidants (oleuropein, ligstroside and related compounds, ****tocopherol, squalene and sodiu...

A New Statistical Approach to Describe the Quality of Extra Virgin Olive Oils Using Near Infrared Spectroscopy (NIR) and Traditional Analytical Parameters
SummaryNIR prediction models were developed for the determination of relevant parameters to evaluate olive oil quality such as acidity (FFA), peroxide value (PV), UV ‐absorption at 232 nm and at 268/270 nm,p‐anisidine value (AnV), isomeric diacylglycerols (DG), and pyropheophytin A (PPP). In addition a new NIR method to estimate the age of olive oil is presented. The relevant wavenumbers are given for the calculation of the parameters and the precision data are presented in comparison to the chemical reference methods. The calibration and validation of the methods were executed with independent data sets (test in t...

Potential of Nuclear Magnetic Resonance for a discriminant characterization of PDO VOOs
AbstractInterest in virgin olive oil (VOO) is growing among consumers and industry due to its well ‐received sensorial attributes and to its higher oxidative stability, as well as to its healthy effects. Furthermore, attention is being increasingly paid to other quality attributes of VOO, such as sustainability and geographical origin. For these reasons, this oil has an important added value an d is exposed to fraudulent practices. In order to guarantee its origin, the European Union (EU) has developed the Protected Designation of Origin (PDO) quality scheme that links the characteristics of a VOO to its geographical ori...

Diversity assessment of Algerian wild and cultivated olive (Olea europeae L.) by molecular, morphological and chemical traits
AbstractAlgeria has several genetic resources on olive trees, mainly made up of small indigenous cultivars, and a very important wild heritage.We characterized 20 olive samples including eight cultivars and twelve wild trees from the province of Bejaia (Algeria), by combining molecular data (13 SSRs), fruit and pit morphological traits, fatty acids composition and phenolic compounds of the EVOOs. The genetic results based on PCoA, UPGMA and AMOVA analysis demonstrated that olive cultivars and wild trees are mixed suggesting kinship relationships between cultivated and wild olive trees and even the presence of cases of syno...

Evaluation of the oxidative stability of cold ‐pressed rapeseed oil by Rancimat and Pressure Differential Scanning Calorimetry measurement
AbstractCold ‐pressed market rapeseed oils were evaluated for oxidative stability using two accelerated methods: Rancimat and Pressure Differential Scanning Calorimetry. In the study, oils were also determined to their acid, peroxide and p‐anisidine value, fatty acid composition, antioxidants capacity and ph enolic compounds content. Obtained results of oxidative stability have been correlated to determine the possibility of using interchangeably tested methods. To examine the impact of individual quality factors on oil oxidative stability the Principal Components Analysis was applied. Analysed oils wer e characterised...

NMR Studies on Italian PDO Olive Oils and their Potential in Olive ‐Tree‐Derived Products Characterization
Nuclear magnetic resonance spectroscopy (NMR) is used to discriminate Italian Protected Designation of Origin (PDO) extra ‐virgin olive oils (EVOOs) from EVOOs of other countries, Italian PDO EVOOs of different restricted area within the same Italian region, and EVOOs obtained from different cultivars. The chemical constituents of olive‐tree‐derived products are also determined. Results strongly support the use o f NMR by control agencies and regulatory authorities. In Italy, 42 PDO extra virgin olive oil (EVOOs) are present to date, with the chronologically first one registered in late 1996. PDO EVOOs are broadly di...

Application of High Intensity Ultrasound to Accelerate Crystallization of Anhydrous Milk Fat and Rapeseed Oil Blends
In this study, the impact of high intensity ultrasound (HIU) treatment on anhydrous milk fat and milk fat/rapeseed oil blends with 10 –30 w/w% rapeseed oil is examined. Effects of HIU treatment on crystallization kinetics, thermal behavior, microstructure, texture, and oxidation are evaluated. HIU treatment results in an acceleration of the crystallization process, especially for blends with a high rapeseed oil content. HIU tr eatment reduces the crystal size, however, HIU treatment does not have any significant effects on the melting behavior or hardness. No significant effects of HIU treatment on secondary oxidation ...

Comparative chemical composition and bioactivity of Opuntia ficus ‐indica Sanguigna and Surfarina seed oils obtained by traditional and ultrasound‐assisted extraction procedures
This study investigated the seed oils obtained from two different varieties ofOpuntia ficus ‐indica (Sanguigna and Surfarina) growing in Sicily, Italy. Soxhlet and ultrasound ‐assisted extraction procedures were used to obtain the seed oils. The fatty acid profile, γ‐tocopherols, carotenoid content, and the bioactivity in terms of the antioxidant effects (using ABTS, DPPH, FRAP and β‐carotene bleaching tests), and carbohydrate‐hydrolysing enzyme inhibitory acti vity (α‐amylase and α‐glucosidase) were determined. The extraction procedure did not significantly affect the fatty acid composition of the oil, b...

The objectives of this invited paper are to evaluate whether the specific composition and structure of the MFGM and milk polar lipid assemblies, associated with their nutritional and health benefits, could be used to tailor functional emulsions bioinspired by the MFGM ‐coated milk fat globules. Recent knowledge about the structure of the MFGM revealing the heterogeneous distribution of proteins and the formation of ordered lipid domains rich in milk sphingomyelin and cholesterol is presented. The impacts of the unique composition and biophysical properties of m ilk polar lipids on the structure and potential functions of...
