摘要：
The invention refers to products obtained by fractionation of an aqueous extract of agave, consisting in branched fructanes of agave separated by size of molecular chain or degree of polymerization into two types: a) short-chain fructanes (fructo- oligosaccharides) with a degree of polymerization of about 3 to about 10 monomeric units, and b) long-chain fructanes with a degree of polymerization higher than 10. The process through which these products are obtained uses the cores of agave as raw material, which contain fructanes of different degrees of polymerization, and consists in washing the cores of agave, crushing and tearing the fiber thereof for being lixiviated with hot water and obtaining an aqueous extract containing the soluble solids of agave. The extract is clarified by coagulation, sedimentation and filtration for separating the insoluble solids present therein and for being purified by ion exchange and activated carbon. The purified extract is fractioned by tangential ul trafiltration. The obtained products have nutraceutical properties, thus they can be used as food supplements or functional ingredients in the manufacture of food products.Esta invención se refiere a los productos obtenidos por fraccionación de un extracto acuoso de agave, consistentes en fructanos ramificados de agave separados por tamaño de cadena molecular o grado de polimerización en dos tipos: a) fructanos de cadena corta (fructo-oligosacáridos) con un grado de polimerización entre 3 y 10 unidades monoméricas, y b) fructanos de cadena larga con un grado de polimerización mayor a 10. El proceso mediante el cual se obtienen estos productos utiliza como materia prima las piñas o cabezas de agave las cuales contiene fructanos de diferentes grados de polimerización y consiste en lavar las piñas de agave, triturarlas y desgarrar la fibra que las constituye para lixiviarla con agua caliente y obtener un extracto acuoso que contiene los sólidos solubles del agave. El extracto se clarifica
