  • Patent number: 8840760
    Abstract: The object of the process of the invention is to increase the retention of starch in the sheet of paper in order to reduce operating costs and increase the physical characteristics of the paper. To that end, it has been envisaged that trivalent cationic salts are added, metered into the slurry or in the process for obtaining starch in powder form or by mixing a percentage of trivalent salts in powder form with the starch in powder form, seeking the solution of said salts in the slurry, so that they dissolve during the dispersion of the slurry in the process for obtaining the sheet of paper. Organic polymers such as polyacrylamides, polyvinylamides and polydadmacs could optionally be applied in addition to said salts.

  • Publication number: 20140141480
    Abstract: Mixtures of ethanol and water are dehydrated using starch pearls to adsorb and remove water. Vapor-phase adsorption equilibrium capacities of cassava starch pellets (tapioca pearls) having different particle sizes are disclosed, and tapioca pearl particles are shown to be surprisingly more effective for dehydrating 88 to 97% w/w feed ethanol than corn grits. The adsorption equilibrium curve and BET surface area measurement show that the adsorption capacity of tapioca pearls is a function of surface area available to water molecules. SEM images demonstrate that the particle architecture required for the adsorption and dehydration properties is that of a core-shell configuration with pre-gel starch acting as a central scaffold holding together other particles to the outer layer of the particle. The outer surface area of the pearls, populated with dry starch granules, is the main factor determining the adsorption capacity of the pearls.

  • Publication number: 20120266869
    Abstract: Disclosed is a cold-water soluble starch and a process for preparing same. Generally, the process comprises providing a hydroxyalkyl starch and applying a shearing force to the starch in an extruder in the presence of moisture, the force and the moisture each being sufficient to gelatinize at least substantially all of the granules of the starch to thereby form a sheared starch. The starch is heated to its gelatinization temperature after the starch has passed partially through the barrel of the extruder, with the moisture being maintained at a level sufficiently high to allow gelatinization but sufficiency low to protect the starch from becoming too sticky to extrude. The extruded starch product thus formed may be used in connection with a number of film-forming, coating, and other applications.

  • Patent number: 7815876
    Abstract: The reactor pump for hydrolytic splitting of cellulose is configured to pump cellulose, under high pressure, with low availability of sugar into a reactor. The reactor has an upstream transition segment connected to a downstream reaction chamber. The transition segment has an inlet that is smaller than the outlet. The inner walls taper outward. The chamber has an inlet that is larger than the discharge outlet. The inner walls taper inward. The transition segment outlet has an area that is substantially the same as the area of the chamber inlet. Back pressure in the chamber forms a cellulose plug within the inlet of the transition segment. The plug stops cellulose from escaping out the inlet. High pressure pumping forms a cellulose plug within the discharge outlet of the chamber. The plug slows downstream movement of the cooking cellulose giving the cellulose time to cook. Cooking cellulose begins to breakdown under heat and the injection of acid, if required.

    Abstract: The present invention discloses a process for modifying starches comprising subjecting a non-pregelatinised starch and/or flour to a superheated steam treatment, wherein said superheated steam treatment is carried out in a reaction chamber of a reactor, said reaction chamber having at least one inlet and at least one outlet, and wherein the temperature of the superheated steam at the inlet of the reaction chamber is in the range of 150 to 650° C., preferably 250 to 550° C., more preferably 350 to 450° C., and wherein the temperature of the superheated steam at the outlet of the reaction chamber is in the range of 105 to 155° C., preferably 115 to 140° C., more preferably 115 to 125° C. The invention further refers to the starches obtained and baby foods, infant foods, sauces, soups, puddings, dressings, bakery creams, gravies and beverages comprising said starches.

  • Publication number: 20080230050
    Abstract: The present invention relates to a method for the physical treatment of starch (derivatives) using densified gases, in which essentially the starting material is treated at process temperatures between 20 and 200° C. and at process pressures between 50 and 800° C. for at least one minute, the density of the densified gas (mixture) being >180 kg/m3. Suitable starting materials are, in particular, native plant starches, starch from genetically modified plants, or physically and/or chemically modified starches. The treatment with, in particular, densified carbon dioxide, can be carried out under defined pressure change sequences, for which, in particular, liquid aids, such as water or suitable organic solvents, can also be added.

  • Patent number: 7422638
    Abstract: Sago-based gelling starches and the use thereof. Such modified starches exhibit exceptionally fast gelling properties, high gel strengths, and exceptional elasticity. These properties allow for significantly reduced processing times, including reduced hold times. Further, the higher gel strength allows for reduced starch levels without loss of final product gel strength integrity or texture. The instant gelling starches are particularly useful in food systems of the type that gel upon standing, such as pie and cream fillings, puddings, spreads, and jellies.

  • Patent number: 7276126
    Abstract: A process for producing alpha-amylase resistant starch comprises extruding a feed starch at a temperature in the range of about 60-220° C., thereby producing a product alpha-amylase resistant starch. The feed starch can be in the form of an aqueous slurry or paste that has a dry solids concentration of at least about 50% by weight. The process optionally can include the additional step of heating the product starch to a temperature of at least about 90° C. in the presence of moisture, to increase further the alpha-amylase resistance of the product.

  • Patent number: 7189288
    Abstract: A process for producing an enzyme-resistant starch uses an aqueous feed composition that comprises (i) starch that contains at least about 50% by weight amylose, (ii) water, and (iii) alcohol. The concentration of starch in the feed composition is between about 5% and about 50% by weight, and the pH of the feed composition is between about 3.5 and about 6.5. In a first heating step, the feed composition is heated to a temperature between about 130–170° C. for about 0.1–3.0 hours. The feed composition is cooled to a temperature between about 4–70° C. for about 0.1–6.0 hours. In a second heating step, the feed composition is heated to a temperature between about 110–150° C. for about 0.1–10.0 hours. The starch is separated from the majority of the water and alcohol and is dried.
