Environmental and Genetic Effects on the Composition of Palm Oil From Hybrid Plant Clones of Caiaué and Oil Palm

open access: yesJournal of the American Oil Chemists' Society, EarlyView.
ABSTRACT The interspecific hybrids (IEH OxG) obtained from the crossing of Elaeis oleifera (Eo) and Elaeis guineensis (Eg) are resistant to some diseases that affect Eg in some regions of South America, and commercial growing in several countries has been established.

Influence of Direct Saponification Conditions on Sterol Yield and Composition of the Unsaponifiable Fraction of the Microalga Isochrysis galbana and the Seaweed Ascophyllum nodosum

open access: yesJournal of the American Oil Chemists' Society, EarlyView.
ABSTRACT Saponification is a key step for recovering the unsaponifiable fraction (USF) of lipids, which contains bioactive sterols, tocopherols, and carotenoids. This study optimized direct saponification conditions (50–300 g L−1 KOH; 60°C–100°C) to recover sterol‐rich USFs from the microalga Isochrysis galbana and the brown seaweed Ascophyllum nodosum,

Variation of air--water gas transfer with wind stress and surface viscoelasticity [PDF]

open access: yes, 1995
Previous parameterizations of gas transfer velocity have attempted to cast this quantity as a function of wind speed or wind-stress. This study demonstrates that the presence of a surface film is effective at reducing the gas transfer velocity at ...

Acidogenic fermentation of pretreated food waste under psychrophilic conditions for volatile fatty acids production

open access: yesBiofuels, Bioproducts and Biorefining, EarlyView.
Abstract Mixed‐culture fermentation generally produces volatile fatty acids (VFAs) as a mixture of C2–C6 acids. Among operational parameters, temperature has a distinct effect on the microorganisms' metabolic activity, which can shift the composition of the metabolites.

In Situ Synthesis of Hypercrosslinked Polymer as Stationary Phase for Capillary Gas Chromatography

open access: yesSeparations
Hypercrosslinked polymers (HCPs) constructed by the Friedel–Crafts alkylation reaction of aromatic compounds have emerged as a new class of porous materials with unique merit. Herein, a HCP named HCP-TPB was coated onto a capillary column through in situ

Macaúba (Acrocomia aculeata) pulp oil ethylic biodiesel using lipase from Aspergillus oryzae: kinetic and process parameters

open access: yesBiofuels, Bioproducts and Biorefining, EarlyView.
Abstract Macaúba (Acrocomia aculeata), a native species from Brazilian biomes, has emerged as a sustainable alternative to vegetable oil production. Its fruit presents high oil yield (3–6 ton/ha), extracted from its kernel and pulp. While the kernel is suitable for food and cosmetics application, the pulp oil has been considered as a promising ...

Biogas purification and enrichment: sustainability metrics analysis of dry anaerobic digester with cashew apple bagasse substrate

open access: yesBiofuels, Bioproducts and Biorefining, EarlyView.
Abstract This study hypothesizes that cashew apple bagasse‐based anaerobic digestion, combined with biochar purification, enhances biogas quality and sustainability. This study aims to investigate the performance and sustainability of a biochar‐based biogas purification technology using cashew apple bagasse as a substrate, with a focus on environmental

DESIGN AND USE OF A THERMAL-CONDUCTIVITY DETECTOR AT REDUCED PRESSURE FOR TEMPERATURE-PROGRAMMED CAPILLARY GAS-CHROMATOGRAPHY

open access: yes, 1993
Based on a systematic study of the response characteristics of a thermal conductivity detector (TCD) at reduced pressure, a newly designed TCD was constructed and evaluated for use in temperature-programmed capillary gas chromatography.

Valorization of bark extracts from Cerrado and Amazon species: phenolic characterization, antioxidant capacity, and photoprotective potential for circular bioeconomy applications

open access: yesBiofuels, Bioproducts and Biorefining, EarlyView.
Abstract Tree bark remains an underexploited source of high‐value‐added phenolic compounds with potential circular bioeconomy applications. This work characterized bark extracts from two species of distinct Brazilian biomes, Stryphnodendron adstringens (Cerrado) and Myrcia eximia (Amazon), obtained with three solvents (ethanol, methanol and acetone ...
