摘要:
The invention relates to a method for obtaining value-determining contents, such as flavoring substances, vitamins, and polyphenols, from foods (13), having the following steps: a) providing a food (13), b) adding a plant oil (15) as an extraction means, c) grinding the food (13) and the plant oil (15) into a mash (21), and d) separating the mash into an extraction phase, which is an oil phase (25), and a solid phase (29) as a raffinate phase. The food (13) and the plant oil (19) are ground very finely, said grinding process being defined in that the food (13) together with the plant oil (15) is ground until the oil phase (25) has an average particle size of less than 300 µm, preferably less than 100 µm, particularly preferably less than 20 µm.
摘要:
A plant for producing virgin olive oil comprises at least one crushing device, configured for producing an oily paste, at least one kneading tank, configured for carrying out a gradual heating and a continuous remixing of the oily paste, at least one decanter, configured for carrying out the separation of the oily paste into an oily phase and into a solid and aqueous phase, and at least one separator, configured for carrying out a final removal of the water and solid residues from the oily phase. The plant also comprises at least one first thermal conditioner configured to instantly cool the oily paste provided by the crushing device to a first temperature value in order to reduce degradation of phenolic compounds and/or to increase the formation of volatile compounds influencing the aroma of the virgin olive oil.
摘要:
A method of producing fatty acid esters in situ from microbial biomass such as algae is provided by treating microbial biomass with a solution containing an alcohol and at least one α-hydroxysulfonic acid. Fatty acid ester can be directly recovered from the treated microbial biomass. The α-hydroxysulfonic acid can be easily removed from the treated microbial biomass and recycled.
摘要:
A system and method of extracting essential oils from plant material through the use of a low pressure alcohol-based closed system that includes a solvent chamber connected to a material column that in turn is connected to a recovery chamber. Plant material in the material column and the solvent in the solvent chamber are cooled using a cooling liquid, such as nitrogen. A vacuum pump connected to the recovery chamber creates a vacuum in the recovery chamber to draw the cooled solvent through the cooled plant material and extract essential oils, which are collected in the recovery chamber.

Production Method of Hazelnut Extract Containing Ethyl Alcohol by Supercritical Extraction The present invention relates to a production method for producing hazelnut extract, which method consists of the process steps of roasting the hazelnut fruit, extracting the roasted hazelnuts, with the addition of ethyl alcohol for 45-90 minutes in a supercritical extractor under 300-350 bar pressure, at 40-50ºC temperature and under 100-125g/min supercritical carbon dioxide flow rate, and then, evaporating the ethyl alcohol in the extract.
摘要:
The present invention relates to processes for reducing the amount of phorbol esters in the oil and cake produced from Jatropha curcas seed kernels. The invention also relates to the uses of the products of the process for oil, animal feed and anti-microbial, anti-mollusc, anti-tumor or bio-pesticide agents.
摘要:
The invention relates to a method for producing a concentrate of polymer proanthocyanidins with a concentration of more than 40%, characterised by the use of enzymatic treatments and by the absence of organic solvents and/or the extraction of organic solvents. This concentrate can be used as a functional ingredient, a food supplement, a cosmetic product and a pharmaceutical product.
摘要:
The present invention relates to hydrothermally processed microorganism biomass and a feed or food composition comprising said biomass for use in preventing or reducing the adverse effects of mycotoxinsin animal or human digestive tract.
摘要:
Continuous extraction concentration and isolation units are constructed with at least one extraction chambers containing extractable material. Without disruption of total fluid flow in the unit: an extraction chamber completely depleted of extract can be refilled with fresh extractable material or can be replaced with an extraction chamber containing fresh extractable material. Extract are continuously separated from one or more solvents in expansion chambers and removed. All solvents can be retained within the unit. One or more compressors circulate the fluids through the extraction chambers, the expansion chamber, and a condenser, where the expansion chamber and the condenser can be coupled as a heat exchanger. One or more isolators can be included for selectively removing components that are extracted from the plant material without disruption of the process and provide the removed components in concentrated or pure form.
