Physically modified starch products are prepared using pressure and heat such as by extruding starting material starch which optionally can be admixed with gums and/or surfactants. The properties of the products can be adjusted by varying the moisture content of the materials in the extruder and the temperature and pressure at a die plate provided at the discharge end of the extruder. The screw elements in the extruder are selected with the goal of using enough mixing elements at the discharge end to keep the pressure in the extruder barrel as high as possible over a short distance. The physically modified starch products are made up of partially to fully cooked starch and some raw starch particles. They are highly dispersible in cold or hot water with hot or cold swelling viscosity.

Starch products having hot or cold water dispersibility and hot or cold

Carrier-type corrugating adhesives are prepared using a carrier phase comprising a combination of tapioca fiber and corn fiber or tapioca fiber and spent germ flake as a substitute for modified or unmodified corn starch to provide an adhesive composition.

Corrugating adhesives employing tapioca fiber

Corrugating adhesives of the carrier, no-carrier and carrier-no-carrier type having excellent dry pin adhesion, green strength and improved water resistance are prepared with solubilized plant fiber as a complete or partial substitute for starch. The adhesive composition contains polyvinyl alcohol, solubilized fiber and, optionally, from about 0.1% to about 99% added starch by weight based on total solubilized fiber and added starch. When the adhesive is the carrier type or the carrier-no-carrier type, the fiber can be solubilized in situ during the process of preparing the carrier phase.

An improved process is disclosed for producing corn fiber having a high total dietary fiber content and a reduced SO.sub.2 content. A dilute aqueous slurry of the corn fiber obtained from the corn wet-milling process is separated by means of a hydroclone to give a fiber fraction of enhanced total dietary fiber content. This fiber fraction is then passed into a first centrifugal paddle screen followed by two stages of washing, including washing with a second centrifugal paddle screen. Fiber from the second centrifugal paddle screen, which is optionally pressed to remove water that contains dissolved SO.sub.2, is dried to make the final product. Heated water can be used during washing to remove additional SO.sub.2 more effectively.

Process for producing a high total dietary corn fiber

A process for producing corn fiber having a high total dietary fiber content. A dilute aqueous slurry of the corn fiber obtained from the corn wet-millng process is separated by means of a hydroclone to give a fiber fraction of enhanced total dietary fiber content. This fiber fraction may then be passed into a centrifual paddle screen to give a product of even higher total dietary fiber content.

A process for the separation of corn fiber from dry-milled corn. The corn fiber is separated frm the dry-milled corn by employing a Multified Electrostatic Separator using dielectrophoresis.
