The present application is directed to the preparation of low viscosity bio-oils from the hydrothermal liquefaction (HTL) of lignocellulosic biomass in the presence of a crude glycerol and water mixture achieving a high biomass conversion ratio. The modified HTL process allows the direct use of crude glycerol as an effective solvent for biomass liquefaction creating a highly efficient and cost-effective process. Furthermore, the resulting bio-oils containing liquefied biomass, crude glycerol and water, were successfully applied as an inexpensive green substitute in the preparation of bio-based phenol formaldehyde (BPF) adhesives which retain bonding strengths (dry or wet strength) as required by ASTM standard and free formaldehyde emission levels at the F*** and F**** level according to the JIS standard.

A method for producing a high viscosity, low volatiles blown stripped plant-based oil is provided. The method may include the steps of: (i) obtaining a plant-based oil; (ii) heating the oil to at least 90C; (iii) passing air through the heated oil to produce a blown oil having a viscosity of at least 200 cSt at 40C; (iv) stripping the blown oil from step (iii) to reduce an acid value of the blown oil to from 5 mg KOH/g to about 9 mg KOH/g; (v) adding a polyol to the stripped oil from (iv), and (vi) stripping the oil from step (v) to reduce the acid value of the oil to less than 5.0 mg KOH/g or less.

A multi-stage homogenization method for degumming triglyceride oil is used to increase oil yield and reduce impurities. Two high-pressure homogenizers are used in series. The homogenizers have multiple flow constrictions to finely disperse reagents in the oil while simultaneously suppressing cavitation in the fluid. A separation step can be used to remove the phosphatides and other impurities from the treated oil to form a purified oil product.

Disclosed is a chromatographic process complex for the refining of krill oil extract including desalting, removal of impurities such as trimethylamine oxide (TMAO), and the production of krill oil products including desalted krill oil extract, polar lipid products having polar lipid contents greater than 50 wt-% on a dry or solvent free basis, neutral lipid streams for biodiesel production and astaxanthin. The refinery includes a continuous desalting zone, a fixed bed polar lipid extraction zone to adsorb neutral lipids and astaxanthin to provide a polar lipid extract stream comprising solvent and polar lipids and being essentially free of neutral lipids and astaxanthin, and an astaxanthin separation zone to recover essentially pure astaxanthin and provide a neutral lipid stream. The enriched products of the krill oil refinery are essentially free of TMAO and salt and provide products which can be used as dietary supplements and as medicinal additives.

A method for producing hemp oil, comprising decarboxylation of CBDA in hemp oil; short-path evaporation of CBD from the decarboxylated hemp oil to produce CBD oil; selective THC to CBN conversion performed on the decarboxylated hemp oil.

The process for extracting carboxylic acids having from one to nine carbons, produced by microorganisms (M) in a fermentation reactor (1) by anaerobic fermentation from fermentable biomass (S), said extraction being of liquid-liquid type, which comprises at least the following steps: a) choosing an endogenous extraction solvent among at least one of the carboxylic acids produced during the anaerobic fermentation, such that the number of carbons of the solvent is greater than or equal to the number of carbons of the carboxylic acid to be extracted, having a density below that of water and the boiling point of which is above 70 C. under normal conditions of pressure, b) bringing the extraction solvent chosen into contact (2) with the fermentation medium, without interrupting the fermentation, outside the fermentation reactor (1), c) separating (6) the fermentative metabolites from the extraction solvent by means of at least one distillation, d) collecting and storing or using (14) the fermentative metabolites obtained in step c). The invention also relates to a facility for carrying out the process.

A method for extracting oils from sauces while simultaneously determining fat content, peroxide value, and acid value is disclosed. The method is simple to operate and requires uncomplicated equipment. It features a short testing cycle and high efficiency, and suitable for the extraction of oils from oil-rich emulsified encapsulated sauces (such as salad dressings) with high extraction rates. The determination of peroxide value and acid value is not affected by pretreatment methods, ensuring more representative results. It addresses the challenges of difficult oil separation and extraction from oil-rich emulsified encapsulated sauces and solves significant issues encountered when using acid hydrolysis and alkaline hydrolysis methods to determine peroxide value and acid value. It enables the simultaneous monitoring of three physicochemical indicators (fat content, peroxide value, and acid value). This high-efficiency method is particularly suitable for tracking and monitoring during the production process, thereby enhancing production efficiency and reducing production costs.

The present disclosure describes methods for reducing the content of minerals, metals, ions, and/or other undesirable contaminants in vegetable oil, such as corn oil, obtained from fermentation of ground vegetable material. In one aspect, the methods herein produce distiller's corn oil having low amounts of minerals, metals, ions, and/or other contaminants rendering the corn oil more suitable for various further uses, such as biofuel production, with little to no additional refining.

The present invention relates to isolated polypeptides having phospholipase C activity and isolated polynucleotides encoding the polypeptides. The invention also relates to nucleic acid constructs, vectors, and host cells comprising the polynucleotides as well as methods of producing and using the polypeptides.

A centrifugation device includes a feeding tube defining a longitudinal axis, and a plurality of centrifugal plates extending longitudinally and radially around the feeding tube and rotatable about the longitudinal axis. The centrifugal plates have coarse surfaces coated with one or more layers of polymer material. A centrifugation tank is disposed coaxially with the feeding tube and around the centrifugal plates. A sidewall of the tank is provided with micro/nano filters. Methods for isolation of algal biomass from an algae and aqueous mixture, and extraction of oil from kitchen residue and/or microalgae are also disclosed.
