Abstract:
The invention relates to a method for impregnating a support matrix with solid and/or liquid compounds using a compressed gas or a compressed mixture of gases at gas densities ranging from 0.15 to 1.3 kg/l and at least two unsymmetrical pressure changes (pulsations). The method is further characterized in that both a multitude of impregnating substances such as biologically active compounds, technical materials or metal-organic compounds, as well as support matrices of biological origin and organic or inorganic substances can be used that have large inner surfaces and/or inner surfaces that are difficult to access.
Abstract:
The invention relates to a method for obtaining fruit wax from plant constituents, said method being carried out essentially using compressed C 2 -C 4 hydrocarbons. Unlike previous extraction methods with supercritical CO 2 , the inventive method can be carried out at low pressures and with a reduced extraction means throughput. Residues from the fruit treatment, especially peel from the juicing process, are used as starting materials. Preferred extraction agents are ethane, propane, butane and the mixtures thereof, the extraction itself being carried out in batches at pressures of
Abstract translation:基本上借助压实的C 2 SUB 2 C SUB 4 CUB进行根据本发明的用于从蔬菜成分获得果实蜡的方法。 与先前使用的超临界CO 2萃取过程相反,所提出的过程可以在较低的压力下进行并且具有降低的萃取剂通过量。 作为起始原料,来自水果加工的残留物,特别是来自果汁提取物的果皮,成为问题。 优选的萃取剂是乙烷,丙烷,丁烷及其混合物,其中甚至在<50mPa的压力和= 70℃的温度下,在4至20kg / kg的起始材料的萃取剂通过量下分批进行萃取。 提取的果蜡适用于化妆品或药物制剂,特别适用于皮肤的护理和治疗。
Abstract:
The invention concerns a method for stably flavouring drinks by means of solid, solvent-inert, particulate carrier materials loaded with flavouring agents having a large specific surface in which inorganic silicon, aluminium and/or carbon-containing compounds from the group comprising silicates, aluminium oxides and activated carbons, which optionally contain portions of water, are used as carrier materials. Silica gels, kieselguhr, activated and/or calcined clays, gamma-Al 2 O 3 and alumina oxide xerogels are particularly suitable as carrier materials which should have a specific surface between 0.1 and 1000 m 2 /g and a particle size of >=10 mum. Suitable pore sizes of the carrier materials are those between 0.3 and 5000 nm. Suitable flavouring agents are essential oils, citrus oils, fruit essences and flavour extracts, for the loading of which the carrier materials are introduced into liquids containing flavouring agents or are sprayed with these. The method can in particular be used to stably flavour hot drinks for long periods.

Abstract:
The invention relates to a method for the selective isolation of valuable substances with the aid of compressed C2 to C4 hydrocarbons, such as for example ethane, propane, and/or butane, according to which a starting material is used, which contains the valuable substances in an absorbed and/or adsorbed form. Activated carbon, alumina, silicic acids, zeoliths or polysaccharides, which are charged accordingly with the valuable materials, are used as the starting materials for said method, which is carried out preferably in a continuous operation at temperatures of
Abstract:
Procedimiento para la extracción continua de una fase líquida y/o grasa F1 que comprende sustancias aromatizantes, con un gas G1 en estado líquido o supercrítico, (a) mezclándose una corriente continua SF1 de F1 con una corriente continua SG1 de G1 en corriente paralela, mediante lo cual se obtiene una corriente continua S1 de una mezcla de SF1 y SG1; (b) conduciéndose la corriente S1 obtenida en el paso (a) continuamente a través de un reactor R con una superficie interna OI y una superficie externa OA, entrando en contacto S1 con la superficie interna OI del tubo R y extrayéndose de este modo en S1 las sustancias aromatizantes contenidas en SF1 al menos parcialmente en SG1 al atravesar el tubo R, mediante lo cual, después de que S1 atraviesa el tubo R, y tras salida de S1 del tubo R, se obtiene una corriente continua S2 de una mezcla de una corriente continua SF2 a partir de la fase líqúida F2 empobrecida en sustancias aromatizantes frente a SF1, y una corriente continua SG2 a partir del gas G2 líquido y/o supercrítico enriquecido con sustancias aromatizantes frente a SG1, caracterizado por que (c) al menos una parte de la corriente S2 entra en contacto con la superficie externa OA del tubo R al menos parcialmente, de modo que tiene lugar un intercambio de calor entre S2 y S1, y caracterizado por que el sentido de flujo de la corriente S1 en la salida del tubo R está orientado al menos parcialmente contra la fuerza de gravedad.
