It is intended to produce highly water-soluble inulin having a high added value from these plants. It is also intended to produce an agave syrup, tequila, an alcoholic drink or highly water-soluble inulin from the squeezed residue. Agave plant bulbs (several tens kg) having been employed in producing tequila called pina are cut into small pieces and enzymes therein are inactivated and the texture is softened either at room temperature or under heating. Next, the pieces are squeezed to give a liquid extract which is then refined by using an adsorbent resin.

    Abstract: A method and an apparatus for performing a continuous reaction with at least one liquid reaction phase incorporating at least one starting compound in the presence of at least one solid-phase catalyst, wherein the phases to be contacted are circulated through at least one pulsed reaction column (1). The liquid reaction phase is continuously fed into the middle or lower portion of the pulsed column (1), the liquid phase is circulated upwards through the pulsed column (1), and a counterflow made up of lumps (9) of a solid selective extraction compound is continuously circulated. Furthermore, each solid catalyst is continuously circulated through the pulsed column (1) in contact with the liquid phase.

  • Patent number: 5932015
    Abstract: Provides an economical method for manufacturing high-value added crystalline maltitol and crystalline mixture solid containing this by means of a process wherein a syrup with a maltose content of 40 to 75% by weight in the solid component is subjected to catalytic hydrogenation, the sugar alcohol syrup is then subjected to chromatographic separation to produce a maltitol-containing syrup fraction with a high maltitol content in the solid component, and the maltitol-containing syrup fraction is then subjected to chromatographic separation.

  • Patent number: 5925190
    Abstract: Inulins are pyrolyzed to di-D-fructose dianhydrides in good yield by heating at atmospheric pressure to a temperature sufficiently high to melt the inulin, or pyrolyzing in the presence of a hydroxy carboxylic acid such as citric acid, to melt temperatures of the mixture. The pyrolyzed inulins are used in foodstuffs to increase the relative proportions of bifido bacteria in the digestive tracts of humans and domesticated animals.

  • Patent number: 5904941
    Abstract: The present invention is directed to a viscosifier prepared by enzymatically hydrolyzing a ungelatinized, granular starch or flour. Such starch or flour is useful as an ingredient in food products, particularly fruit- or vegetable-based products, as a viscosifier and may be used to replace pectin or tomato solids.

  • Patent number: 5837060
    Abstract: The invention relates to a process for the manufacture of a starch hydrolysate of low polymolecularity index which may be used in particular in continuous ambulatory peritoneal dialysis. This process consists essentially in acid and enzymatic hydrolysis of a waxy starch milk and then chromatography on macroporous strong cationic resins of the hydrolysate obtained. The starch hydrolysate is essentially characterized by a polymolecularity index of less than 2.8, a weight-average molecular weight between 5,000 and 22,500 daltons and a number-average molecular weight below 8,000 daltons.

  • Patent number: 5820687
    Abstract: A economically viable method for producing sugars using concentrated acid hydrolysis of biomass containing cellulose and hemicellulose is disclosed. The cellulose and hemicellulose in the biomass is first decrystallized and then hydrolyzed to produce a hydrolysate containing both sugars and acid. Silica present in the biomass can then be removed for further processing. The remaining solids are then subjected to a second decrystallization and hydrolyzation to optimize the sugar yields. An improved method for separating the sugars from the acid in the hydrolysate is also disclosed. The resulting sugar stream can then be fermented, using an improved method which allows both hexose and pentose sugars to be fermented simultaneously.

  • Patent number: 5782982
    Abstract: A method of removing silica or silicates from solids results from the acid hydrolysis of materials containing cellulose and hemicellulose is disclosed. The method includes the steps of treating the solids with a metal hydroxide solution to produce an extract, reducing the pH of the extract to produce silicic acid, and removing the silicic acid from the extract.
