Microwave-Assisted Extraction of Curcuma longa L. Oil: Optimization, Chemical Structure and Composition, Antioxidant Activity and Comparison with Conventional Soxhlet Extraction
(MDPI, 2021-03-10)
Curcuma root (Curcuma longa L.) is a very important plant in gastronomy and medicine for its unique antiseptic, anti-inflammatory, antimicrobial and antioxidant properties. Conventional methods for the extraction of curcuma ...
Fractionation of non-timber wood from Atlantic mixed forest into high-value lignocellulosic materials
(Taylor & Francis, 2020-03-10)
[EN] The forestry industry in the Basque Country has experienced an abandonment of small-sized forests in which native and introduced species tend to regrow if unattended; thus, requiring an intervention under which proper ...
Extraction of flavonoid compounds from bark using sustainable deep eutectic solvents
(Elsevier, 2021-12)
[EN] The use of green solvents in extraction processes, especially for applications of lignocellulosic biomass, has been extensively studied over the last years. Among the range of different green solvents, deep eutectic ...
Renewable biopolyols from residual aqueous phase resulting after lignin precipitation
(ACS, 2021-02-19)
The aim of this work was to obtain two biopolyols from the liquid residue resulting from the precipitation of lignin contained in two different black liquors, Eucalyptus globulus organosolv black liquor (EOBL) and Pinus ...
Multiproduct biorefinery based on almond shells: impact of the delignification stage on the manufacture of valuable products
(Elsevier, 2020-07-22)
In this work, an integral valorisation of almond shells through a biorefinery approach was studied. The three main components of almond shells were extracted, isolated and characterised. The autohydrolysis process permitted ...
Techno-economic analysis of different integrated biorefinery scenarios using lignocellulosic waste streams as source for phenolic alcohols production
(Elsevier, 2021-02)
The whole process of lignin extraction from a lignocellulosic waste streams (almond shell) by sulfur-free methods and its depolymerization by base catalyzed or solvolysis reactions have been addressed in this work. In ...
Hydrothermal treatments of walnut shells: a potential pretreatment for subsequent product obtaining
(Elsevier, 2020-10-08)
Walnuts are nowadays widely consumed. Since the edible part of walnuts does not account more than 50-60% of their total weight, the total amount of shells produced annually is huge. However, as walnut shells are part of ...
Simultaneous Microwave-Ultrasound Assisted Extraction of Bioactive Compounds from Bark
(2020-08-22)
Larix decidua is one of the fastest growing conifers and one of the most important coniferous tree species in Europe with high importance at wood-based industry; however, the bark generated from the debarking process is ...
Study of a renewable capping agent addition in lignin base catalysed depolymerisation process
(Elsevier, 2020-07-13)
The aim of this work was to study the influence of a renewable capping agent (CA) in the production of monomeric compounds from the depolymerization of an organosolv lignin (Pinus radiata) by a base catalyzed depolymerization ...
Synthesis of advanced bio-based green materials from renewable biopolymers
(Elsevier, 2021-01-30)
Polymeric materials such as hydrogels have become necessary in our daily lives. Hydrogels are three-dimensionally cross-linked polymeric networks that can absorb large amounts of water. Thanks to their properties, hydrogels ...
