Fragrant bioethanol: A valued bioproduct from orange juice and essential oil extraction
2018
Abstract We identify the composition of a less known, yet important bioproduct obtained in relatively high amount during orange fruit processing for juice and essential oil extraction comprised of bioethanol dissolving valued terpenes. Green cosmetic, perfume and biosolvent applications are anticipated.
Abnormal mitotic spindle assembly and cytokinesis induced by D-Limonene in cultured mammalian cells
2013
D-Limonene is found widely in citrus and many other plant species; it is a major constituent of many essential oils and is used as a solvent for commercial purposes. With the discovery of its chemotherapeutic properties against cancer, it is important to investigate the biological effects of the exposure to D-Limonene and elucidate its, as yet unknown, mechanism of action. We reported here that D-Limonene is toxic in V79 Chinese hamster cells in a dose-dependent manner. Moreover, to determine the cellular target of D-Limonene, we performed morphological observations and immunocytochemical analysis and we showed that this drug has a direct effect on dividing cells preventing assembly of mito…
Identification of highly effective antitrypanosomal compounds in essential oils from the Apiaceae family
2018
The Apiaceae family encompasses aromatic plants of economic importance employed in foodstuffs, beverages, perfumery, pharmaceuticals and cosmetics. Apiaceae are rich sources of essential oils because of the wealth of secretory structures (ducts and vittae) they are endowed with. The Apiaceae essential oils are available on an industrial level because of the wide cultivation and disposability of the bulky material from which they are extracted as well as their relatively cheap price. In the fight against protozoal infections, essential oils may represent new therapeutic options. In the present work, we focused on a panel of nine Apiaceae species (Siler montamon, Sison amomum, Echinophora spi…
Aroma transfers in and through plastic packagings: orange juice andd-limonene. A review. Part II: overall sorption mechanisms and parameters—a litera…
1997
Nowadays, the quality of foodstuffs has more than ever included the notion that packaging1 contact is not always wholesome. It can alter the packaged food product by flavour scalping and can also affect the food by off-flavour release. Much research has been carried out to better understand the mass transfers involved with various synthetic polymeric films. Orange juice and one of its major volatile constituents, d-limonene, were probably amongst the first food products to be thoroughly studied. Yet, no extensive literature review has been undertaken in order to obtain a general and accurate description of the sorption and diffusion phenomena. This review underlines the effects of packaging…
Aroma transfers in and through plastic packagings: orange juice andd-limonene. A review. Part I: Orange juice aroma sorption
1997
Orange juice and one of its major volatile constituents, d-limonene, were probably amongst the first food products to be thoroughly studied. Yet, no extensive literature review has been undertaken in order to obtain a general and accurate description of the sorption and diffusion phenomena. This review underlines the effects of packaging on the organoleptic quality of citrus juices; it therefore presents a focused interest on d-limonene mass transfer experimental results with a variety of plastic polymers. Part I deals with first, loss of organoleptic quality of orange juice during storage and d-limonene sorption is discussed. Second, generalites are presented concerning volatiles transfer …
Poly (lactic acid)/D-limonene/ZnO bio-nanocomposites with antimicrobial properties
2022
[EN] Antimicrobial films of poly (lactic acid) (PLA)/D-limonene/zinc oxide (ZnO)-based bio-nanocomposites were prepared via melt compounding and subsequent thermocompression. D-limonene was incorporated at concentrations of 10 or 20 wt%, and ZnO pure nanoparticles and those organically modified with oleic acid (O-ZnO), with an average diameter of 13.5 nm, were included at concentrations of 3, 5, and 8 wt%. The plasticizing effect of D-Limonene was corroborated by a decrease in the glass transition temperature compared to pure PLA. The presence of ZnO and O-ZnO in the PLA matrix promoted a slight increase in the degree of crystallinity due to its nucleant performance. Although ZnO and O-ZnO …
Vitamin D3 in fish oil extracted with limonene from anchovy leftovers
2020
Abstract Aiming to identify and assess the amount of fat-soluble vitamins in anchovy oil extracted with d-limonene from anchovy fillet leftovers via the UHPLC–HESI–MS advanced mass spectrometry analytical technique, this study shows that only vitamin D3 is present in anchovy by-product oil. The sum of the quantities of the three isomers of vitamin D3 amounts to 0.0815 μg vitamin D3 per g oil, namely a 81.5 μg/kg content, in good agreement with the typical amounts of vitamin D3 in fish oils (ranging from 18 to 350 μg/kg).
Theoretical study of the OH addition to the endocyclic and exocyclic double bonds of the d-limonene
2005
Abstract The initial step of the d-limonene + OH gas-phase reaction mechanism was investigated by means of ab initio calculations. We have considered eight different possibilities for the OH addition, corresponding to the two C–C double bonds, the two C atoms of each double bond, and the syn or anti orientation, with respect to the isopropenyl group (endocyclic attack) or the ring cycle (exocyclic attack). Activation energies calculated at the QCISD(T)/6-31G(d)//UMP2/6-31G(d) level, show that there are preferred orientations for the OH addition under atmospheric conditions of temperature and pressure.
