Abstract In recent years, a novel medium with similar properties to ionic liquids but additional advantages regarding cost, environmental impact, and synthesis has been developed: deep eutectic solvents (DESs). These result from the association between an organic salt (ammonium or phosphonium) hydrogen‐bond donor such as alcohols, acids, amides. To date, availability of green, inexpensive easy handle is almost non‐existent. Therefore, DESs currently arouse growing interest in many research...
Lipid oxidation constitutes the main source of degradation lipid-rich foods, including food emulsions. The complexity reactions at play combined with increased demand from consumers for less processed and more natural foods result in additional challenges controlling this phenomenon. This review provides an overview insights acquired over past two decades on understanding lipid oil-in-water (O/W) After introducing general structure O/W emulsions classical mechanisms oxidation, contribution...
This work reports the first lipase-catalyzed reactions between substrates of different polarities using deep eutectic solvents as a medium. The model reaction consisted lipophilization process based on alcoholysis phenolic esters immobilized Candida antarctica lipase B biocatalyst. Results showed that water could dramatically improve activity and change reactivity substrates. Indeed, very low conversions (<2%) were observed in pure DES, whereas DES–water binary mixtures, quantitative...
Electronic cigarette (EC) usage has increased exponentially, but limited data are available on its potential harmful effects. We tested for the presence of reactive, short-lived free radicals in EC aerosols by electron paramagnetic resonance spectroscopy (EPR) using spin-trap phenyl-N-tert-butylnitrone (PBN). Radicals were detected from all ECs and eliquids (2.5 × 1013 to 10.3 per puff at 3.3 V) eliquid solvents propylene glycol glycerol "dry puffing". These results demonstrate, first time,...
Lipases are versatile enzymes that can be used for various kinds of biocatalyzed reactions. Owing to their selectivity and mild reaction conditions, they often considered as more interesting than classical chemical catalysts. Besides application in oil fat processes, these have proved very attractive other lipase-catalyzed This review discusses the latest results where lipases epoxidation lipid substrates (namely fatty acids derivatives) phenolic compounds. chemo-enzymatic process involves a...
Caffeic, ferulic, and coumaric acids were lipophilized with saturated fatty alcohols (C1-C20). The antioxidant properties of these hydroxycinnamic their alkyl esters evaluated in various assays. Furthermore, the efficiency compounds was a simple o/w microemulsion using conjugated autoxidizable triene (CAT) assay. All phenolipids had radical scavenging, reducing power, metal chelating properties. Only caffeic acid caffeates able to form complex iron via catechol group phenolic ring. In...
Coffee pulp (CP), cocoa husk (CH), and pod (CPH) are the main agro-residues from coffee industries. They sources of useful biomolecules, such as phenolic compounds, fibers, alkaloids, among others. In this study, different compositions deep eutectic solvents (DES) were investigated a green sustainable extraction media, with respect to their capacity. The yields evaluated using heat stirring-assisted (HSE) or ultrasound-probe assisted (UPAE).The results showed an important effect DES...
Natural deep eutectic solvents (NaDES) are new natural in green chemistry that some cases have been shown to allow better extraction of plant bioactive molecules compared conventional and higher phenolic compound absorption rodents. However, there is a serious lack information regarding their vivo safety. The purpose this study was verify the safety NaDES (betaine:glycerol (1:2 mole ratio) water) extract from coffee beans, rich polyphenols. Twelve 6-week-old male Wistar rats were randomized...
The encapsulation β-carotene in whey protein concentrate (WPC) capsules through the emulsion electrospraying technique was studied, using deep eutectic solvents (DES) as solvents. These novel are characterized by negligible volatility, a liquid state far below 0 °C, broad range of polarity, high solubilization power strength for wide compounds, especially poorly water-soluble extraction ability, and stabilization ability some natural products. Four DES formulations were used, based on...
Lipid oxidation is a well-recognized issue in dried food emulsions, such as infant milk formula. Antioxidants can be used to mitigate this issue; however, their efficiency complex systems far from understood. In study, antioxidant polarity varied through the alkyl chain length of gallic acid esters (0-16 carbon atoms) incorporated O/W emulsions that are subsequently spray-dried. During processing and subsequent storage samples, antioxidants with more than eight atoms effective. Both for...
The new generation of designer solvents, such as deep eutectic solvents (DES), are generally claimed to be renewable and environmentally friendly. Nevertheless, this classification depends entirely on the nature selected components. DES derived from choline chloride (ChCl) combined with a safe hydrogen‐bond donor, urea, seemed ideal for design eco‐friendly processes. In mixtures water, it has been successfully used lipase‐catalyzed reactions polar substrates. However, no studies have yet...
Abstract Research on natural sources of polyunsaturated fatty acids (PUFAs) for both food and nutraceutical prospects has significantly grown in recent years. Some plant oils lipid extracts contain carotenoids, xanthophylls, sterols, and/or phenolic compounds that can provoke a hydroperoxides (LOOHs) overestimation when quantifying them using nonselective colorimetric assays. Herein, we have optimized mid‐infrared method Fourier‐transform infrared spectroscopy coupled with attenuated total...
