  • Patent number: 7186431
    Abstract: A composition for sweetening foodstuffs comprises at least one sweetening agent (e.g., polyol, monosaccharide, disaccharide, trisaccharide, and combinations thereof), and inulin, which comprises at least about 25 percent by weight of the combination of sweetening agent and inulin. A foodstuff comprises a sweetening composition comprising at least one sweetening agent (e.g., polyol, monosaccharide, disaccharide, trisaccharide, and combinations thereof), and inulin, which comprises at least about 25 percent by weight of the combination of sweetening agent and inulin.

  • Patent number: 6569488
    Abstract: The process for preparing the novel inulin products includes extracting inulin with water from subdivided plant materials, holding the inulin rich extraction water in a settling tank while maintaining the temperature from about 0° C. to 7° C. which causes higher molecular weight polysaccharides to separate from water soluble lower molecular weight polysaccharides, and separating the higher molecular weight inulin fructose fractions from the more water soluble lower molecular weight inulin fractions.

  • Patent number: 6419978
    Abstract: Novel fractions of inulin are disclosed which have improved water solubility and/or water miscibility at ambient temperatures. The novel fractions are extracted from plant materials containing inulin and have molecular weights below about 2288. The process for preparing the novel fractions includes extracting inulin with water from subdivided plant materials, holding the inulin rich extraction water in a settling tank while maintaining the temperature from about 0° C. to 7° C. which causes higher molecular weight polysaccharides to separate from water soluble lower molecular weight polysaccharides, and separating the water soluble fractions from the higher molecular weight inulin fractions.

  • Patent number: 6399142
    Abstract: Novel liquid food products are disclosed which contain water, and inulin fractions having at least about 75% by weight of polysaccharides extracted from inulin-containing plant materials in which the polysaccharides have molecular weights in the range from about 2288 and below. The food products also may contain sweeteners, for example, artificial sweeteners, such as aspartame, saccharin, sucralose, or one or more of the polyols.

  • Patent number: 5958500
    Abstract: Processes for extracting three sugars, fructose, sucrose and glucose, from dates are disclosed. Pitted dates are frozen and subdivided into particles. The particles are contacted with a heated water solution to extract the sugars from the date fibers. The sugar enriched water solution is separated from the date fibers by passing the water solution through one or more milli-screens. The sugar enriched water solution may be purified, and also may be treated to reduce the water content. The sugar solution containing the three sugars is a novel food product which can be used as a sweetener, for example, for sweetening soft drinks. Alternatively, the liquid product may be freeze-dried, vacuum oven-dried or spray-dried to produce a novel solid product containing the three sugars. The date fibers are dewatered, and admixed with ground date seeds to produce another novel food product.

  • Patent number: 5891433
    Abstract: Small particles and fines included along with larger subdivided solids are treated with water base liquid extraction medium to extract soluble solids therein in a process using milli-screens with milli-sized openings of less than about 0.095 inches across. The milli-screen openings may be kept open for the passage of liquids with specially-designed wipers and/or back-flushing from a liquid compartment and/or rotation of the milli-screen past the matrix of subdivided solids, the subdivided solids themselves acting as a screen cleaner. The invention is useful in batch or continuous diffusers for extracting soluble solids from subdivided solids containing small particles and fines.

  • Patent number: 5824356
    Abstract: There is disclosed method and apparatus for cleaning roots, tubers, bulbs, and the like, for example, sugar beets, chicory, Jerusalem artichokes, dahlia, potato, and onions (hereinafter "articles"). In the apparatus, spaced horizontal rollers have helices on their cylindrical surfaces which scroll the articles laterally to the ends of the rollers where they are deposited on a slide that removes them from the cleaner, or, optionally, returns the articles to the cleaner at strategically located lower positions for stalk removal and/or leaf stripping, or for other desired cleaning. The first sets of rollers are designed to separate small chips, small stones and loose soil from the articles. The next sets of rollers are designed to remove adhering soil and/or mud, weeds, and larger stones. Strategic placement sizing, rotational speed, and direction of rotation of the helices on the rollers are instrumental in removing leaves, stalks, weeds, breaking up dirt clods and mud balls, and cleaning of the articles.
