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).
Determination of trace elements in gluten-free food for celiac people by ICP-MS
2014
Abstract This paper is the first analytical approach to the study of twenty heavy metals in the gluten-free foods for celiac people. Only the ICP-MS technique was used. One of the advantages about the use of ICP-MS for this characterization is the high sensitivity that improved the limits of quantification levels for some elements that are present at low quantities in some samples. The concentration values of As, Ba, Cd, Co, Cr, Cu, Fe, Hg, Mn, Mo, Ni, Pb, Sb, Se, Sn, V and Zn in seventeen gluten-free food samples are reported. The highest arsenic and molybdenum levels were measured in Rice noodle from China (0.088 and 0.47 mg kg − 1 , respectively). The highest concentrations of some metal…
High Yields of Shrimp Oil Rich in Omega-3 and Natural Astaxanthin from Shrimp Waste
2020
A valued marine oil rich in omega-3 lipids and natural astaxanthin is obtained with remarkably high yield (up to S wt %) extending to pink shrimp waste (head and carapace) using the approach to extract fish oil from fish processing byproducts using D-limonene. Biobased limonene is an excellent solvent for both unsaturated lipids and astaxanthin-based carotenoids preventing oxidative degradation during the extraction cycle including solvent separation at 85 degrees C. Explaining the deep red color of the shrimp oil obtained, computational simulation suggests that D-limonene is also a good solvent for natural astaxanthin abundant in shrimp.
Volatile Compounds of Lemon and Grapefruit IntegroPectin
2020
An HS-SPME GC-MS analysis of the volatile compounds adsorbed at the outer surface of lemon and grapefruit pectins obtained via the hydrodynamic cavitation of industrial waste streams of lemon and grapefruit peels in water suggests important new findings en route to understanding the powerful and broad biological activity of these new pectic materials. In agreement with the ultralow degree of esterification of these pectins, the high amount of highly bioactive &alpha
Omega-3 Extraction from Anchovy Fillet Leftovers with Limonene: Chemical, Economic, and Technical Aspects
2019
International audience; We investigate selected chemical, technical, and economic aspects of the production of fish oil rich in polyunsaturated omega-3 fatty acids from anchovy filleting leftovers using d-limonene as the extraction solvent at ambient temperature and pressure. Entirely derived from the orange peel prior to orange squeezing for juice production, the bio-based solvent is easily recovered, affording a circular economy process with significant potential for practical applications.
Superior Antibacterial Activity of Integral Lemon Pectin Extracted via Hydrodynamic Cavitation
2020
Abstract Pectin extracted via hydrodynamic cavitation in water only from waste lemon peel and further isolated via freeze drying displays significant antibacterial activity against Staphylococcus aureus, a Gram positive pathogen which easily contaminates food. The antibacterial effect of the new IntegroPectin is largely superior to that of commercial citrus pectin, opening the way to advanced applications of a new bioproduct now obtainable in large amounts and at low cost from citrus juice industry's waste.
